6 Signs You Need To Schedule An Appointment For AC Repair Service | Charleston, SC

Summer in Charleston, SC can get very hot and humid; therefore, you rely greatly on your air conditioning system. On an average summer day, the temperature can reach 88 degrees. When you combine the humidity with the heat, it feels a lot hotter. It is more comfortable to stay in your air-conditioned home on days like this than it is spending time outdoors. If your air conditioner breaks down, it will be very difficult to stay cool and comfortable.

The best way to prevent a complete air conditioner breakdown is to recognize the signs that you need AC repair service early. If you can recognize the signs early, you can prevent a small issue from becoming something major that would require an expensive repair.

#1 Thermostat Issues

The thermostat in your home is your HVAC system’s brain. It tells your system when to cool and heat your home. It also tells the system when to turn on and off and the desired temperature. If your thermostat isn’t functioning properly, your air conditioner won’t register the set commands. There are a few signs to let you know that your thermostat is failing.

  • No power to the thermostat, even after you changed the batteries.
  • The thermostat isn’t responding
  • Nothing happens when you turn on the AC
  • The air conditioner comes on and stays on even after your home has reached the desired temperature.
  • The air conditioner cuts out before the desired temperature has been reached.

When you schedule an appointment for an AC repair service, the tech will inspect your thermostat. If they find that it has failed, you should discuss your options. Over the last several years, thermostat technology has improved. You can purchase a programmable thermostat, a Wi-Fi thermostat, or a smart thermostat. Each of these can help you save money and can make controlling your thermostat easier and more convenient.

#2 Warm Air Coming From the Vents

One of the most obvious signs you need to call a professional in AC repairs is if the air coming from the vents in your Charleston, SC home is warm. Before you call your local HVAC company, make sure your thermostat is set correctly. First, the thermostat needs to be set to the cooling mode. Next, make sure that the temperature in the house is warmer than the temperature setting. If the thermostat is set correctly, you should schedule an appointment for an AC repair service. There are a few issues that could be causing the problem.

  • A faulty thermostat
  • The Freon level is low
  • There is an issue with the system’s compressor
  • The AC has reached its maximum lifespan and needs to be replaced.

Because there are so many issues that could be causing this problem, you will need a professional in AC repairs to determine the source of the problem so the necessary repair can be made.

#3 Poor Airflow

If the airflow coming from the vents in your Charleston, SC, home is poor, it will be difficult for your home to reach the desired temperature. The system will need to work harder to keep your home cool, which can cause an increase in your energy bills. In addition, the excess strain on the system can reduce the system’s lifespan. There are a couple of issues that could be causing the issue.

  • Clogged air ducts: You can clean your home daily, but dust, dirt, and other debris will still end up in your air ducts. When large amounts of debris accumulate in the air ducts, it can restrict the airflow. Also, when your AC is running, the debris will circulate in the air and affect your home’s air quality.


  • Damage to the air ducts: If there is a crack in the air ducts, the cold air will escape through the crack, reducing the airflow coming from the vents.


  • Damaged blower: Your AC system’s blower is responsible for pushing the cold air to the vents. If the blower is damaged or not functioning properly, you will have poor airflow.

When you schedule an appointment for an AC repair service, the tech will inspect your air ducts and the system to find the source of the problem.

#4 Strange Sounds

If the AC in your home is functioning properly, it should be relatively quiet. You may hear a soft clicking sound when the system kicks on and off and nothing more.

Strange sounds coming from the system signify an issue that would require AC repair service. The sounds often signify a loose or broken part. If you hear a high-pitched screaming, turn off the system immediately and call a professional in AC repairs. This sound indicates dangerously high pressure, and you shouldn’t use the AC until the problem has been resolved.

#5 Strange Smells

If you smell something strange when your air conditioner is running, you should schedule an appointment with an AC repair professional. The issue with the AC depends on the smell.

  • Mold: A moldy smell could mean that there is mold growth in the air ducts. This is a serious issue because the mold spores will circulate through the air when the system is running. Breathing in mold spores can cause allergy symptoms, respiratory issues, and a weakened immune system. An AC repair professional can remove the mold using an antimicrobial fogger. There could also be mold in the system itself, which may require an AC replacement.


  • Burning: If you smell something burning, turn off your air conditioner at once and call an AC repair professional. The smell is likely due to an electrical issue that can cause an electrical fire if you ignore the issue.

#6 Moisture Around the Unit

There should never be moisture or fluid pooling around your air conditioner. If there is, you should call an AC repair service immediately. You could have a loose or disconnected condensate hose, or the system could be leaking Freon, which is a serious issue.

It is best to schedule an appointment for an AC repair service as soon as you discover the moisture.

Benefits Of Annual Heating And AC Service | Charleston, SC

Your HVAC system plays an important role in keeping your house comfortable for you and your family throughout the year. During winter, the heating unit takes the responsibility of heating the air to keep you and your family warm. During summer, the air conditioner takes over and starts pumping out the excessive heat and humidity from your house to keep the rooms cooler than the weather outside. For your HVAC system to keep working as it should, you must subject it to routine maintenance. In other words, you need to be in touch with a dependable HVAC company that offers routine heating and AC service. Below are the benefits you can expect from subjecting your HVAC system to routine maintenance.

Improve the Lifespan of Your HVAC System

Your HVAC system is not designed to last forever. However, for it to serve you for as long as the manufacturer intended, it must always be working at its optimum level. However, your HVAC is not a system that you install and forget. Indeed, for it to continue operating optimally, it must be subjected to annual maintenance. Otherwise, some parts of your HVAC system could get subjected to unnecessary stress that might cause the system to wear out more rapidly and suffer terminal damage sooner than expected. Regular heating and AC service will keep your HVAC system working optimally and consequently extend its lifespan.

Improved Comfort

As mentioned above, your HVAC system needs routine maintenance to continue working optimally. Therefore, routine maintenance has an effect on the efficacy of the system. If you decide to ignore routine heating and AC service, your HVAC system will gradually become less effective in keeping your house comfortable. For instance, if there are unchecked leaks in the ductwork, you may realize that some rooms will not be warmed or cooled according to your wishes. On the other hand, routine HVAC service will ensure that any mechanical or electrical issues that might negatively affect the performance of your HVAC system are corrected quickly to keep your house comfortable throughout the year.

Save Energy

If you live in Charleston, SC, then your HVAC system might be one of the most significant consumers of energy in your house. If you do not pay attention to routine heating and AC service, your system might even consume more energy and cause your energy bills to skyrocket. On the other hand, regular HVAC service will go a long way in minimizing your energy consumption. In other words, by ensuring that your HVAC system is properly maintained, you can keep it running optimally and efficiently, which is good for both the environment and your bank account.

Prevent Emergency HVAC Breakdown

Like any other electrical and mechanical system, your HVAC system is prone to breakdown. But have you ever thought of what would happen if your HVAC system broke down on a hot summer afternoon or a cold winter night? Of course, you do not want to have such an experience. The good news is that you can do something to prevent it. Through routine heating and AC service, you can ensure that any developing HVAC issues are identified and fixed before getting out of hand and cause your system to malfunction when you need it most. In other words, routine HVAC service will prevent you from having to call an HVAC company for emergency services, which tends to cost more.

Keep Your House Healthier

In addition to keeping your home’s temperatures within a comfortable range throughout the year, your HVAC system is also responsible for the quality of your home’s indoor air. Unfortunately, in the absence of routine heating and AC repair service, the system might end up making your indoor air quality worse. For instance, lack of adequate HVAC system maintenance can cause dust, pathogens, pollen, and other allergens to fill the air ducts. When this happens, some of the pathogens and allergens will end up in your house and eventually lead to allergy flare-ups and other illnesses. On the other hand, routine heating and AC service will keep the filters and the air ducts clean, and consequently make your house a healthy dwelling for you and your family.

Improved Safety

Some HVAC issues could be hazardous. For instance, if your furnace is not burning fuel efficiently, it could produce carbon monoxide, which can be fatal. Besides, there are electrical faults that could lead to a fire, posing a serious safety issue in your house. The good news is that such calamities can be avoided by simply ensuring that your HVAC system is subjected to routine maintenance. During the routine heating and AC service, your HVAC services provider will thoroughly check your system for any signs of safety concerns and ensure that they are fixed before they can put your home and family in danger.

The Bottom Line

Overall, it is apparent that for your HVAC system to continue running efficiently and safely throughout the years, you need to subject it to routine maintenance. Some benefits you can expect from routine heating and AC maintenance include improved comfort and air quality. Besides, ensuring that you get regular heating and AC service can help you save money and keep your family healthy. If you are looking for a dependable heating and AC service expert in Charleston, SC, Carney & Son 72 Degrees Air Conditioning and Heating is an excellent HVAC company to consider. We have a team of highly experienced HVAC experts committed to ensuring that our client’s HVAC systems are running efficiently and optimally throughout the year.

Air Conditioning And Heating Service | Charleston, SC

We have all suffered an air conditioning or heating breakdown at some point and desperately needing quick air conditioning and heating service. Not having your AC unit working on a hot humid summer’s day in Charleston, SC. can make life unbearable and dangerous.

Without a constant supply of cool air from your AC, there is a greater chance of suffering from heat exhaustion, dehydration, and heatstroke. We do not get many extremely frigid days during the winter months, but you will want a working heater or furnace to keep warm during those chilly evenings.

It is important for the people of Charleston, SC to be able to turn to a reliable air conditioning and heating service company. They want a company with the best-trained technicians, available 24/7 and ready to help sort out their problems quickly. So, they turn to us at Carney & Son 72 Degrees for an air conditioning and heating service.

When Do You Need an Air Conditioning and Heating Service in Charleston, SC?

It should come as no surprise that the busiest time for our technicians is the period between late fall and the early summer. The best thing you can do for your peace of mind is schedule an air conditioning and heating service during the shoulder seasons when the climate is more moderate.

Carney & Son 72 Degrees Heating and Air Conditioning offer a subscription service that automatically tells us when your climate appliances need a check-up. It is an affordable way to increase the efficiency of your furnace or air conditioner and it catches problems while they are still small and easily repairable. Without a regular air conditioning and heating service, there is an increased chance that your AC unit or furnace could break down.

If you have not had a service in a while, then your environmental appliances may experience some of these symptoms.

  • Frost and Ice Forming on the Evaporator Coil – To work efficiently the evaporator coil needs a constant supply of warm air to be blowing over it.


  • Normally, warm air is extracted from your home by a fan – Then blown over the coil. Liquid coolant in the coil absorbs the heat from the warm air and cools it. Then, the cooler air is now blown back into your home.


  • There could be several reasons for frost and ice appearing on your evaporator coil.


  • Problems with the fan – A faulty fan will not be able to supply enough airflow over the evaporator coils. It won’t be capable of producing enough air to extract from the warm air.


  • The air filters are dirty – A dirty air filter will also restrict the airflow over the evaporator coil.


  • Air filters haven’t been cleaned or replaced regularly.


  • Low coolant levels – Without an ideal level of coolant in the air conditioner, frost and ice will form on the evaporator coil. Less coolant will mean a decrease in the air conditioner’s efficiency and a hotter home or office.


  • Dirty evaporator coil –dirt will accumulate on the evaporator coil over time. The dirt will act as an insulating layer and reduce the rate at which the warm air transfers its heat to the coil and coolant. Any dirt on the coil needs to be removed during cleaning.


  • As the evaporator coil freezes it causes other components in the air conditioner to overwork to keep the required temperature steady. This increases the wear and tear on the unit and your energy bills. An air conditioning and heating service from Carney & Son 72 Degrees Air Conditioning and Heating will stop these problems from occurring.
  • The furnace is incapable of reaching the set temperature.


  • Knocking, clunking, or other unusual noises from the heating unit.


  • A complete lack of heating in the house.


  • Weird smells or smoke are serious indicators, leave the house and call a professional, and do not go back inside until an authority in heating and gas appliances says it is safe to do so.

Problems with the Furnace

The furnace is the largest component in your HVAC or heater system. The furnace has a fan that draws fresh air through air vents from the outside into a combustion chamber and is mixed with gas or other fuel, to produce heat. The fan now blows the hot combustion gases over a heat exchanger, which then heats fresh air which is blown through the home’s air ducts.

Common issues with furnaces include:

  • Dirty air filters -these will restrict airflow into the combustion chamber and cause a weak flame.


  • Dirty or blocked air vents – the vents supply fresh air for combustion and expel exhaust gases such as carbon dioxide, and carbon monoxide back out. Failure to do either will prevent combustion.


  • Faulty electronics – A faulty pressure switch will shut the furnace down. It makes sure the inducer fan is running and ensures there is enough airflow to allow combustion.


  • An air conditioning and heating service are needed to ensure the smooth running of your furnace.

The Vital Role Of Heating And AC Service Professionals In Energy Efficiency And Environmental Protection | Charleston, SC

Air conditioning produces a lot of greenhouse gases. Almost 50% of energy consumption for an average household in Charleston, SC, is used for heating and cooling systems. Over 90% of American homes use air conditioners to some extent, and air conditioners use approximately 6% of all energy consumed by the entire United States each year. This means that air conditioning releases about 100 million tons of carbon dioxide annually. Heating and AC service professionals can have a significant impact on energy efficiency and carbon emissions.

Energy Efficiency Ratings

Most air conditioning units are rated for energy efficiency. ENERGY STAR rated units include SEER, or seasonal energy efficiency ratio, ratings. SEER ratings indicate how much cooling is produced for the amount of energy used. Traditional central air units may be rated up to 27.5 SEER, while ductless units may be up to 33.1 SEER. Heating units may be rated for heating seasonal performance factor, or HSPF, and annual fuel utilization efficiency, or AFUE. A heating and AC service professional can explain what each rating means in practical terms.

Units with high energy efficiency ratings use less electricity or gas than less efficient models to achieve the same results. Improved energy efficiency is good for the environment and lowers the cost of heating or cooling a home. Ask your local heating and AC service provider about a new Energy Star qualified system if the system in your home is over 10 years old or you notice unexplained increases in the electric bills.

HVAC Zoning

An HVAC zoning system, also known as zoned HVAC, may be beneficial for your home as well. A zoning system tracks your household heating and cooling preferences and trends and helps you create customized temperature zones throughout the home. Some zoning systems include programmable thermostats that can be set and monitored with a tablet or smartphone. This helps the system maintain comfortable temperatures without constantly watching and adjusting a more conventional thermostat. A heating and AC service technician can install dampers in the ductwork to regulate or redirect air to specific rooms.

Zoned HVAC systems reduce wasted energy by limiting the amount of cooled or heated airflow to unused rooms. Most households can benefit from an HVAC zoning system. Almost all of us can think of a room that seems to be too hot or too cold on a regular basis. Family members may have different ideas regarding comfortable temperatures. Although energy savings vary, some home or business owners may use up to 35% less energy after installing zoning systems. Your local heating and AC service provider can install an HVAC zoning system and help you customize it to fit your household needs.

Some homeowners may see a very noticeable difference by switching to a zoned HVAC system. These systems are especially beneficial for homes with large windows or top floors that are always warmer than rooms on ground level. Zoning systems may also improve the air quality in rooms that always feel oppressive and stuffy, and zoning is perfect for maintaining appropriate temperatures in home offices or gyms that may require cooler temperatures than the rest of the house.


Changes in refrigerants are also lessening the environmental impact of HVAC systems. R-22 refrigerant, used by many older AC units, is harmful to the environment and may have a negative impact on the ozone layer. Older refrigerants are being replaced with other types of refrigerants, such as R-410A, which also leads to energy savings for homeowners. Your local heating and AC service technicians can help you integrate energy efficient technologies in your home.

Heat Pumps

Some popular traditional heating and cooling systems include gas furnaces, boilers, electric baseboard heat, and split system air conditions. Heat pumps may not sound very familiar, but a heat pump is another type of HVAC system for heating or cooling. Heat pumps use mechanical energy to pull heat from the air and move it. Although heat pump technology has been around for a while, it’s only recently improved enough to use in areas where temperatures may drop below 20 degrees Fahrenheit on a regular basis.

Air source heat pumps absorb heat from indoor air and move it outside to provide air conditioning. They remove heat from outdoor air and moves it inside to provide heating. This may sound ludicrous on the surface, but air always contains some level of heat, even in frigid temperatures. Other types of heat pumps absorb heat from water instead of air, and geothermal heat pumps use heat from deep underground to heat water pipes. Both water and geothermal pumps are extremely energy efficient, but they can’t be installed everywhere. An air source heat pump works almost anywhere. Your local heating and AC service provider can tell you which type of heat pump is possible in your location.

Heat transfer requires much less energy than heat generation, which explains why heat pumps are much more energy efficient than most conventional heating methods. In some ways, heat pumps are technically more than 100% efficient because the energy produced in the form of heat is larger than the amount of energy needed to power the pump.

The pump does have to work harder to get heat from cold air, so heat pumps still aren’t very common in northern states with cold climates, However, they work well in Charleston, SC. If you decide a heat pump is right for your home, there are several types to choose from, such as split system pumps, packaged heat pumps, and ducted or ductless pumps. Consult a heating and AC service technician to decide which type is best for your home.

Contact Carney & Son 72 Degrees Air Conditioning and Heating in Charleston, SC, if you’re interested in improving energy efficiency in your home. The experienced heating and AC service professionals at Carney & Son can provide assistance to find appropriate energy efficient units for your home. They could help you set up an HVAC zoning system to fit your needs.

Is It The Right Time For An Air Conditioner Replacement? | Charleston, SC

Once you have installed an air conditioner, the unit will need routine maintenance to continue operating optimally. Repairs may also be necessary from time to time. However, no AC unit is designed to last forever, and no matter how much care to give your unit, there will come a time when it will need to be replaced. Unfortunately, the right time to replace an air conditioner is not obvious in most cases. There are many factors to be considered and telltale signs to watch out for, and therefore, the average homeowner may find it difficult to tell if it is time to repair or replace their AC units. Below are some signs indicating that you need an air conditioner replacement.

Your AC Is Older Than Ten Years

As mentioned earlier, air conditioners are not made to last forever. On average, the lifespan of older air conditioners ranges between 10 to 12 years. Newer models can last between 15 and 20 years. As your AC approaches the end of its lifespan, it will become less efficient and require more attention from an HVAC repair expert. If you are not sure when your AC was manufactured, you can pick its manufacturing date from the serial number. If you don’t know how to interpret the serial number, you can ask an HVAC expert to assist you. If you find that your unit is older than a decade and is showing signs of inefficiency or physical deterioration, it is wise for you to start thinking of seeking air conditioner replacement services.

Your AC Requires More Frequent Repairs

Like any other electrical equipment, your air conditioner will need repairs from time to time. However, under normal circumstances, AC repairs should be few and far between. Therefore, if your air conditioner keeps breaking down, forcing you to call an AC repair company every few weeks, there is a serious problem. In such as case, you need to start talking to your HVAC company about the need for a replacement, especially if your AC is older than ten years. This is because frequent AC breakdowns can be quite costly and inconvenient.

The AC Is Becoming Less Effective

Nobody else understands the effectiveness of your air conditioner than yourself. Therefore, when there is an anomaly in how it works, your will certainly know. For instance, if your air conditioner is well maintained, but it is not cooling your entire home evenly, then it could be getting less effective due to age or some other factors. In such a situation, it makes sense for you to start thinking of an air conditioner replacement in Charleston, SC because the system will eventually become completely unable to regulate the temperatures in your home, and consequently make your home uncomfortable for you and your family, particularly during summers and winters when temperatures can go the extremes.

Your Energy Bills Have Skyrocketed

Of course, the HVAC system is one of the most significant consumers of energy in your house. Unfortunately, your AC can become quite inefficient with age, and consequently push your energy bills up. Therefore, if your energy bills have skyrocketed but your utility company has not increased its cost per unit, your AC could be consuming more energy than it should. If you are not sure, you can consult your HVAC services provider to determine if there is something that can be done to restore your air conditioner’s initial levels of efficiency. If nothing can be done to correct the issue, then it is imperative for you to ask your HVAC services provider to guide you on air conditioner replacement.

Your AC Uses R-22 Freon

In the past, some manufacturers of air conditioners would use R-22 Freon as a refrigerant. However, after it was discovered that Freon is a threat to the ozone layer, the government resolved to ban the importation and production of Freon in the United States from January 2020. Therefore, if your air conditioner uses R-22 Freon, it is important for you to know that you will not find the appropriate refrigerant for it should it need a refill. As such, if the refrigerant level goes down for some reason, you could be forced to live under sweltering heat until you can replace your unit. Therefore, it is advisable for homeowners who own older air conditioners that use R-22 Freon as a refrigerant to start thinking of seeking air conditioner replacement services.

You Are Facing Expensive Repairs

As mentioned above, it is not unusual for your air conditioner to need some repairs. However, some air conditioner repairs do not make economic sense. For instance, if your air conditioner’s air compressor is irredeemably damaged, replacing it can be quite an uneconomical decision, especially if your unit is almost a decade old. In such a situation, air conditioner replacement could be more economical compared to investing in a replacement air compressor.

The Bottom Line

Overall, it is apparent that your conditioner is not going to serve you forever. If it is well maintained, it should serve you for 10 and 20 years. But even before the official expiry date of your air conditioner, there are several factors that can make it necessary for you to consider air conditioner replacement. For instance, if your AC has become less effective and more inefficient, in spite of doing all the necessary maintenance and tune-ups on time, then you may have to replace the unit to save money in the long run. Similarly, if your air conditioner is having issues that are forcing you to call your HVAC repair company every few weeks or months, then it should be replaced as soon as possible for you to enjoy your peace of mind. If you need an HVAC company offering air conditioner replacement services in Charleston, SC, Carney & Son 72 Degrees Air Conditioning and Heating is an excellent choice.

  • The HVAC not supplying enough hot or cold air.
  • You notice odd smells coming from the HVAC.
  • Hearing strange noises emerging from the HVAC.

You Start to See Frost and Ice and Frost Forming on the Evaporator Coils

Frost and Ice forming on the coil is not a good sign. The evaporator coils are a vital component in your HVAC, as it absorbs the excess heat and humidity from the air in your home. Fans blow the warm air from your home over the coil.

The heat is extracted from the warm air by the coolant in the coil. The coolant is pumped around the HVAC by the compressor unit, passes through the condenser and cooling fins located outside your home. Here the heat is radiated to the outside air and the coolant continues its journey back to the coils.

Any restriction of the warm air been blown over the coils could cause frost and ice to form. These restrictions can be due to dirty filters or faulty fans not blowing enough warm air.

Low coolant levels can also cause frost and ice to form as well as dirt layers forming on the coil. Ignoring the frost and ice building up could lead to a call to a heating and AC repair company.

The Condenser and Cooling Fins Are Dirty

When the coolant reaches the condenser and cooling fins the excess heat from inside your home is radiated to the outside air. As they are located outside a layer of dirt and grime will accumulate on them. This dirt acts as an insulating layer and reduces the rate at which heat is radiated. This will reduce the cooling effect of the HVAC.

The condenser and cooling fins need to be cleaned regularly, and this is also part of a regular service. Moss and weeds can grow on the condenser and fins. These will also need to be removed as they restrict the flow of outside air over them, further reducing the cooling effect. Without cleaning, the condenser could overheat and burn out, leading to a visit from a heating and AC repair company.

Uncalibrated and Poorly Positioned Thermostat

An uncalibrated thermostat or poorly positioned one will increase your energy bills. One placed in direct sunlight or near an open window will miscalculate the temperature and cause the HVAC unit to work harder than it needs.

Close Windows and Doors

The best way to keep your home cool in the summer with the air conditioner on is to keep your windows and doors closed. It is also the best way to keep your room warm in the winter. Open windows and doors will create different temperature regions in your home and cause the HVAC to work harder to compensate.

Heating and AC Repair Company May Need to Check the AC Drain Line

People often forget the AC drain line, if it is blocked for any reason, it may cause the HVAC to shut down. Any water from the warm humid air is collected in the drip pan. This then flows outside via the AC drain line. Moss and Mildew could grow inside the line and block it.

The water now has nowhere to exit the HVAC, it builds up in the drip pan and then overflows into the HVAC and then onto your floor. Any increased humidity and even the smell of mold may be explained by this. Before you ring a heating and AC repair company it may be worth checking to see if the drain line is blocked.

As you can see a problem with one component can impact others. A faulty component will cause the other components to work harder to compensate. Overworked components use more energy and are more likely to overheat, burn out, and need a visit from a heating and AC repair company.

Heating And AC Service Near You | Charleston, SC

Charleston, SC represents one of the largest cities in the state of SC, with the city seated in the Metropolitan Statistical area. Founded in 1670, Charleston is one of the oldest cities in SC.

Families move to Charleston due to its mild weather, proximity to beaches, as well as its unique historical background. Charleston residents have access to three beaches within a 20-minute drive from the downtown area. If you’re looking for beaches that aren’t as congested, then you also have easy access to the beaches in Sullivan’s Island and the Isle of Palms.

Why Are People Choosing To Live in Charleston?

Realtor.com has recently predicted that Charleston would be one of the top leading real estate markets for buyers who want affordable housing. The forecast for a strong real estate market in Charleston turned out to be accurate, as the local real estate market continues to break records.

In several years, it is projected that Charleston, SC will represent one of the top 10 housing markets in the United States, with the Charleston Regional Business Journal explaining that the Charleston real estate market is empowered due to its consistent economy, low unemployment rate, and flourishing cash flow markets. It’s no surprise that many families want to move to Charleston.

However, the reality is that many homes are going to be several decades old. While AC systems are designed to last, some homes may need Heating and AC Services. Regular servicing maximizes the life of your AC and heating system, it is also the best way to obtain optimal and efficient performance from your cooling equipment. When properly taken care of, your AC system will work more efficiently, allowing you to save more money on electric bills and ensure a comfortable indoor environment year-round.

Importance of Heating and AC Service

  1. Heating and AC Services Help Your Family Save money. Preventative maintenance will prevent costly breakdowns, reduce your energy bills, extend the life of your equipment and system, and will ensure that you stay protected under warranty.
  2. Heating and AC Services Improve air quality. The EPA reports that the indoor levels of airborne pathogens can be almost 5 times higher than outdoor levels. This is particularly significant since we spend so much time in our homes. Indoor allergens can be concentrated indoors due to air circulating within a confined space. These allergens range from ordinary household dust that may heighten respiratory issues, to cigarette smoke, mold, and pollen. If you suspect accumulation of mold, then it is best to contact an HVAC technician so that air ducts can be professionally cleaned.
  3. Heating and AC Services Improve comfort. Regular maintenance helps your system produce and distribute cool and warm air throughout the home without any obstructions. Proper maintenance reduces the odds that you’ll come home from work during a hot summer day and find that the cool setting of your HVAC system is not responding anymore.
  4. Heating and AC Service Will Keep Your Home Safer. You’ve heard the horror stories — the home that has unfortunately burned down due to the accumulation of dust in the vents from years of neglect. Or the family who came home after winter break to find a frozen severely damaged home due to a malfunctioning condenser. Preventative HVAC maintenance will safeguard your family against the risk of carbon monoxide, the odorless gas that can potentially be deadly. One of the main reasons why carbon monoxide may spread within a home is due to a failed heat exchanger. Regular HVAC maintenance typically includes a carbon monoxide test that will detect any potential hazards.

Heating and AC Service Maintenance Schedule for Charleston Residences

  • Yearly maintenance. Ensure that you remove any shrubbery, and trim back trees and plants, to ensure that they are at least 3 feet away from any outside equipment. Debris can get trapped in the equipment and affect its efficiency. Keep furniture, garden supplies, and any other home equipment several feet away from AC units. Visually inspect the outside condenser units for any cracks, discoloration, or dirty coils and evaporators. Pay attention to any strange sounds that may emit from outside AC units.


  • Quarterly maintenance. This is the time to schedule an inspection with your HVAC contractor. You may need to have your air filters changed, have the thermostat recalibrated, as well as have electrical components inspected. Broken connections compromise a system’s efficiency and safety.

HVAC Services for the summer and winter months? In the fall, hire a contractor for your heating system’s annual maintenance. During the inspection, our technicians will check the electrical connections, condensate drain, and voltage. Carbon monoxide detectors will also be inspected if you use natural gas or oil for your heating system.

For the summer months, our HVAC technician will inspect the AC for properly working fins, refrigerant levels, and blower system components. The refrigerant lines — the lifeline of your AC system — will also be inspected. Typically your AC system will have two copper lines that go into the AC condenser and a larger line with insulation covering it. During the hot summer months, this line will feel cold to the touch or have condensation on it due to proper refrigerant levels. If the line does not have condensation, then an HVAC technician will need to be called to replace and replenish refrigerant levels.

Why Are We The Best Air Conditioning And Heating Service Company? | Charleston, SC

If you have lived in Charleston, SC, you will know that the summers are often long and hot. By hot we mean that they are often above 90 degrees with humidity levels to match. This is not a good time to have your air conditioner break down, especially if you are looking after young children or older relatives. It is also very stressful if your furnace or water heater has decided to die on a cold day.

In an emergency, you need a dependable air conditioning and heating service company; one that operates 24/7, on weekends and holidays. An air conditioning and heating service company that has many trained technicians available and carries many spare parts for most AC and HVAC manufactured products. You need Carney & Son 72 Degrees Air Conditioning and Heating of Charleston, SC. We provide the highest standards of work at very affordable prices.

Do You Need an Air Conditioning and Heating Service?

We at Carney & Son 72 Degrees Air Conditioning and Heating, highly recommend that you have an annual air conditioning and heating service from one of our many skilled technicians at least once a year.

A regular service will ensure that your air conditioner, heater, or HVAC are working safely and efficiently. You will also get peace of mind knowing that there is less risk the key appliances in your home will break down when you need them most. We suggest that you book your service during quieter periods like during the late spring or autumn.

Be on the Lookout for Any Problems

Even the best-maintained HVAC will break down periodically, but there are some warning signs that you can be on the lookout to avoid that expensive repair.

  • Larger than anticipated energy bills
  • Reduced airflow and cooling effect
  • Reduced air quality
  • Strange smells
  • Strange noises
  • Water pooling around the unit

Larger Than Anticipated Energy Bills

A component in your HVAC can be affected if there is a problem with the other components. For example, if the airflow over the evaporator coil is reduced for any reason, frost and ice can start to form on the coil and it could even completely freeze.

This will cause the coil and other components to have to work harder to maintain the cooling effect. This increases the risk they will overheat and break down. Harder working components will use more energy and drive up your energy bill.

Reduced Airflow and Cooling Effects

A coolant leak means you can expect a reduced cooling effect and a warmer home during the summer months. Less coolant means less cooling. The coolant is in a liquid form in the evaporator coil and changes to a hot gas after it absorbs the heat from the warm air from your home that is blown over it.

The warm air is now cooled and blown back into your home. Without enough coolant, the warm air will not have a chance to be cooled enough resulting in less cool air entering your home. Topping up coolant levels is part of a regular air conditioning and heating service from Carney & Son.

If the fan blowing the air is damaged, then frost and ice can also start to form on the coil, further reducing its effectiveness and reducing the airflow coming from your AC unit.

Reduced Air Quality

A dirty air filter will also reduce the airflow over the evaporator coil, compounding the effects of low levels of coolant and faulty fans. A dirty air filter will not stop as many dirt or pollen particles from entering the AC unit and then your home. This will degrade air quality, increasing the stress on sufferers of chronic breathing conditions such as Asthma. Dirty air filters will be replaced during a regular air conditioning and heating service from Carney & Son.

Strange Smells

During an air conditioning and heating service, one of Carney & Son’s technicians will check for any loose electrical connections, solder, and other signs of damage. A loose connection may cause a short and explain any burning smell. If one of the components is overworking, it will heat up and may give off a burning smell. If you smell any burning, you should call Carney & Son straight, there is now an increased risk of a fire.

Strange Noises

Any strange noises coming from your unit can be disconcerting. A faulty fan can often be the source of that strange noise. Loud screeching sounds could mean a worn-out fan belt or bearings in the fan’s motor. A bent blade could be striking a part of the unit and create a chunking sound. Odd noises are never a good sign and need investigation. Hoping a problem will go away will only lead to an expensive repair.

Water Pooling Around the Unit

People forget that there is an AC drain line. The excess moisture in the warm air is collected in a pan located in the AC unit. It then flows outside through the drain line. Because of the humidity in the line, moss and algae can grow in the drain line and block it. The water in the pan has nowhere to go and overflows into the AC unit and on the floor.

Other Problems Related to Air Conditioning and Heating Service

The condenser and cooling fins need a clean to remove any layers of dirt and any moss or weeds that have grown. These reduce the transfer of heat to the outside and airflow over the condenser and fins.

A poorly calibrated or positioned thermostat will increase your energy bills. If placed in direct sunlight or near an open window it will misread the temperature and cause your AC or HVAC to work harder than it should.

The Top Air Conditioning and Heating Service Company.

Carney & Son understands how worrying it is for families to have their AC or HVAC fail. We put you and your family’s safety first. Our team will respond quickly to any emergency call and all the work will be finished safely and to your total satisfaction.

Knowing The Signs That You Need AC Repair | Charleston, SC

When the temperatures start to climb in Charleston, SC you rely on your air conditioner. During the historic heatwaves now facing the nation, AC units are being pushed to their limits, so they tend to break down and need AC Repair. Sadly AC problems always seem to happen at the worst possible time, when we need them during a hot summer day. Did you know that oftentimes you can avoid a complete AC breakdown by learning to know the signs that your AC is on the verge of a breakdown? It turns out our AC units often tell us that the unit is in need of some attention from an air conditioning company. You can avoid costly AC breakdowns by learning to tell when your AC unit needs some love and care, you just have to learn what your air conditioner is trying to tell you.

The heat is on now in Charleston, SC, so you might want to think about preventive care for your AC unit. Just like your car or truck, so too does your AC unit need preventive care to ensure that it works properly. Cars need an oil change, AC units need things like a filter change. Yet your AC needs more than just the filters changed. The inside unit needs to be cleaned yearly, parts like your condenser coils can build up dirt and grime on them. While it might not seem like a little dirt and grime could end up with you needing AC repair this is exactly the case. Dirt and grime for example building up on the condenser coil can cause the coil to freeze over, which prevents heat transfer, resulting in a slew of problems for your AC unit.

You should have your AC tuned up every spring when Charleston, SC AC companies are the least occupied with service calls for broken down AC units. However, it is never too late to call Carney & Son 72 Degrees Air Conditioning and Heating for an AC tune-up. You might be wondering what exactly happens during an AC tune-up. Your HVAC technician will check your air filter and replace it if it is dirty or clogged up with pet hair. They will also ensure your thermostat is calibrated correctly. They will clean your blower components and your condenser and evaporator coils. The technician will maintain all of the many moving parts of your AC unit, helping you to avoid costly repair. Your technician will also check your refrigerant levels and refill your refrigerant if it is low. Your technician will also determine your voltage and amperage is correct. They will also check over all of the many electrical connections and electronic parts of your system. Your repair technician will also check your blower motor over as well as the blower belt. Pretty much every working part of your system gets inspected, cleaned, and maintained. Any problems that could lead to costly AC repair will likely be caught early or prevented by servicing the unit with an AC tune-up.

Now that we have clarified how important an AC tune-up is to prevent costly AC repair, let us discuss the signs of AC failure or the need for AC replacement. Your air conditioner will likely warn you via sounds, smells, or other signs that it needs servicing or AC repair. Most times if you catch an AC repair early you can avoid costly repairs due to complete breakdowns. Here are the top signs that you are in need of a repair for your home.

Strange Sounds

This is the number one sign you are in need of AC repair for your home. Your AC unit should only emit a low and steady blowing sound indoors. Your outdoor unit will make some loud noises, you just need to learn what noises are normal for the outdoor unit and which ones signify that the unit needs AC repair. Let’s discuss some of the sounds you might hear from an AC unit that signify your unit may need a repair in Charleston, SC.

Banging Sounds

If you are hearing banging noises you are likely dealing with an internal part that has come loose. It might be a component that has shifted out of place. It could be just a matter of a few screws or bolts that need to be tightened. It could also be a faulty spring. You want to attend to this issue before it causes a complete breakdown resulting in the need for costly AC repair.

Buzzing Sounds

If you hear a buzzing noise from your AC chances are you are in need of AC repair for your home. The two most common causes of a buzzing sound coming from your unit are motor problems and capacitor problems. You could also be dealing with loose parts, debris inside of the unit ( which is removed during an AC tune-up!), a dirty condenser coil (Coils are cleaned during a tune-up!), or possible electrical problems. Since you could be dealing with electrical problems you want your AC unit seen as soon as possible to avoid the potential for fire.

Hissing Sounds

This is a sound you do not want to hear. It could signify that you are dealing with a refrigerant leak, as refrigerant escaping the system makes a hissing sound. You want to call your local AC repair company right away if you hear this sound. It can also be an internal valve leak inside of your compressor. You could also be dealing with a compressor problem, so if you hear hissing from your unit yes it is a serious issue.

Bubbling or Gurgling Sounds

If you hear bubbling or gurgling sounds from your AC unit your compressor may have a refrigerant leak. You do not want to be dealing with a refrigerant leak as this can be dangerous for you and your family. If you hear this noise call your local AC repair company right away.


If you hear this noise coming from the outside unit it is often the sign of either loose hardware or a failing motor. The louder the sound is the more serious the problem is in most cases. This sound can also be caused by debris inside the unit. We should point out that any debris inside of the unit is removed during an AC tune-up.

Screeching, Screaming or Squealing

This is the top sign to call your local AC repair company. It can oftentimes signal that components like your blower wheel or fan motor need replacement. If you hear screeching it can also be the sign of damaged belts or bearings inside of your unit. Rarely it can indicate that your unit has a dangerous pressure buildup, which is an emergency situation. If you hear this sound you should turn off the AC unit right away and make that call for AC repair.

Strange Smells

If your air conditioner is starting to emit a strange smell you have a problem. If you are smelling a rotten egg smell coming from your air conditioner you might be dealing with a gas leak, which can be dangerous if left unattended. If you smell an electrical or burning smell you should shut the unit off right away and call your local AC repair company for emergency AC repair service. You do not want to deal with an electrical fire or risk further damage to your AC unit. If you are smelling a musty smell coming from your AC unit you are likely dealing with mold or mildew inside of the unit and/or your ductwork. Mold is a toxic fungus that you do want you and your family to breathe in. Sometimes mold develops due to a clogged duct or excessive moisture inside of your AC unit.

Reduced Air Flow

If your AC unit has reduced airflow you are dealing with a serious problem. For starters your AC unit will have to work extra hard to try and cool down your home, resulting in higher than normal utility bills. Reduced airflow can have many possible causes. One possible cause is a dirty air filter (Which is changed during an AC tune-up, see a pattern here? AC tune-ups are important!), which is a simple matter to fix. Another cause is a frozen evaporator coil. Your evaporator coil is responsible for cooling your home. If the coil gets too cold, ice can form on the coil if the moisture is high. This ice will hinder the flow of air into your home. Frozen evaporator coils happen most often due to two causes, either low airflow from a dirty air filter blocked vents or a blower that is malfunctioning. The other cause is low refrigerant levels. If you have low refrigerant it is most often due to a leak. If you have reduced airflow, call your local AC repair company for service before your unit breaks down completely!

Air Isn’t Cold

If your AC unit is not blowing cold air you have a problem and need to call your local AC repair company for service. The problem likely rests with either your thermostat or low levels of refrigerant in your system. You will want to check your thermostat settings to see if you have the house set to cool down to the right temperature. If everything seems fine with your thermostat the thermostat could be broken or you could be dealing with a refrigerant leak. You do not want to be dealing with a refrigerant leak as this is a gas that is dangerous to you and your family. If you suspect that you are dealing with a refrigerant leak you should call for emergency AC repair service as this is a dangerous situation. You could be dealing with a lesser issue however as some AC units shut down if the AC air filter is clogged. This precautionary measure is to prevent damage to your AC system. Many people do not know how serious an issue a dirty AC filter actually is. You should change your AC filter every 3 months, sooner if you have pets as pet hair can clog an AC filter rather quickly. You can also have warm air blowing from your system if the AC unit has an ice buildup inside of it. If your coils get dirty or your filters get clogged, or if you have a low refrigerant level you could have ice build up in your system. If your AC unit drains get clogged you can also get warm air blowing into your ducts as the AC unit will shut down due to an AC safety feature. If your AC unit’s compressor becomes dirty you can also be dealing with warm airflow. If your refrigerant levels dip too low you can also be dealing with warm air flooding your home through the vents. Only a technician from a licensed AC Repair company can get to the bottom of the issue and make the needed repairs.

Little Air Blows Out of Vents

If you have very little airflow you have a serious problem and will need a local AC repair company to get to the bottom of the issue. This problem is similar to your air not blowing cold. Oftentimes customers report that they feel cool air coming through the vents but the airflow is weak. This problem is likely due to one of two causes. The first cause is a problem with your ducts. Perhaps the ducts have become blocked with dust, grime, and pet hair. If this is the case your ducts will need to be cleaned by a professional AC repair company. In Charleston, SC, Carney & Son 72 Degrees Air Conditioning and Heating specialize in cleaning out clogged ductwork. The other potential issue causing low airflow is if you have a failing compressor. You will need to hire a professional to be sure of the exact cause of your low airflow.

If you have any of the above signs of trouble with your central air conditioner, call the professionals at Carney & Son 72 Degrees Air Conditioning & Heating of Charleston, SC.
