5 Signs That You Need A Heating And AC Service | Charleston, SC

Heating and AC services are required to keep your heating and cooling system in working order. Sometimes it is difficult to determine whether or not you have to hire a contractor to repair your furnace or air conditioner. The sooner you realize that there is a problem, the sooner you can get it fixed. The sooner it gets fixed the less money you will be wasting on ineffective equipment that uses a lot more energy than it is supposed to. Carney & Son 72 Degrees Air Conditioning & Heating in Charleston, SC would like to inform you of five signs that your heating and air conditioning system is in need of a service.

1. It Is Not Working

This is one of the most obvious signs but if your heating or air conditioning system stops working then it is time for you to call your heating and AC service provider to come take a look at what is causing the malfunction. There are a variety of different reasons why your heating and AC system might not be functioning thus it is best to get a professional to take a look at it. They will be able to identify the cause of the malfunction and advise you on possible ways to repair it. They will also be able to repair or replace any problematic components. If your heating system or air conditioner stops working then it is best to call a service provider immediately because you do not want to be left without heating during the winter or without cooled air during the summer.

2. Strange Sounds

When something that is supposed to be silent makes a noise then that is a sign that there is something wrong with your furnace or air conditioner. It is normal for there to be a slight sound when you start up your heating and cooling system but if the sound gets louder or persists then you should hire a heating and AC service provider. If there is a squeaking or grinding sound then you should turn off the system immediately. Something could have broken off and gotten stuck in your system. If you keep the system on then you run the risk of damaging the other components. Carney & Son 72 Degrees Air Conditioning & Heating in Charleston, SC always recommend hiring a professional to come to inspect your heating or AC system. They will know what to look for and how to repair it which will save you a lot of time and effort.

3. Air Flow Problems

Your air conditioner or heating system should be producing treated air at a steady pace. When the airflow becomes irregular or there is no airflow at all then something is amiss. Sometimes certain rooms are hotter or colder than other rooms or it feels like your home is never hot or cold enough. If this is the case then something in your system is faulty and the air conditioner or heating system will work harder than normal to produce the same amount of treated air. This will cause more wear and tear on your system which will lead to more frequent repairs. If you are experiencing any airflow problems then it is best to hire a heating and AC service provider to come to take a look. Sometimes it’s as simple as replacing the filters in the ducts or other times it can be a more serious problem.

4. Foul Smells

There is nothing worse than having your house smell moldy or like burnt dust. You would like your house to smell fresh and clean. If your air conditioner or furnace starts producing a smell then you should call a heating and AC service provider as soon as possible. If there is a slight dusty smell when you first turn on your air conditioner after the winter or your furnace after the summer then it is normal. It is only abnormal when the smell persists for hours or days. The ducts that allow the treated air to flow into your home might be dirty. If you smell mold then there is a chance that moisture got trapped in your system which caused mold to grow. Mold spores can exasperate the symptoms of a person with lung disease. It can also be difficult to remove all traces of mold that is why it is best to hire a professional heating and AC service provider.

5. The System Is Cycling On and Off Frequently

When the air conditioner or heating system has produced enough treated air so that the house is at the ideal temperature, the system will shut off to conserve some energy and will only turn back on when it is required to produce more air for a comfortable temperature. If your air conditioner or heating system turns off and on too frequently then it could be an indication that the thermostat is not working properly. Some of the common things that can cause your system to turn off and on too frequently are low refrigerant levels, clogged filters or the evaporator coil is dirty. It is important to get a heating and AC service provider to do an inspection when your systems are not working as they should. This will prolong the system’s shelf life and spare you some money in the long run.

Now that you know the signs of when you should hire a heating and AC service provider, you can make informed decisions about your heating and cooling system. Carney & Son 72 Degrees Air Conditioning & Heating in Charleston, SC provides a wide range of services that will keep your air conditioning and heating system run at full speed.

Air Conditioner Repair Service: What You Need To Know About Your Air Conditioning System | Charleston, SC

How well do you know your air conditioning system? Do you know how old it is or when it was last serviced? Do you know what signs to look for and when to contact a professional air conditioner repair service provider for assistance? Not many people do. These are important things to be aware of. The better you know your air conditioning system and when to call for help, the better your air conditioning system will be. The best way to care for your air conditioning system Is to hire an HVAC technician for recurrent maintenance services, however, there will be times when an urgent repair is needed. In cases, of a serious air conditioning system malfunction, it is important to have a reputable and effective HVAC technician on hand. If you live in or around the Charleston, SC, area, contact the staff at Carney & Son 2 Defrees Air Conditioning and Heating for all of your air conditioner repair and service needs.

Knowing What to Look For

Preventive maintenance services are typically all you need to care for from your air conditioning system. Your preventive maintenance HVAC technician will periodically inspect, repair, and maintain your air conditioning appliance to ensure optimal operations and fewer breakdowns occur. You can assist with your air conditioning system’s preventive maintenance care by paying attention to your appliance and reporting any anomalies to your local air conditioner repair provider.

In order to know what to look for, you need to know what you are seeing. The air conditioning system is complex. There are many important parts to the air conditioning systems, however, there are some that matter more than others. The most important components of the air conditioning system are the coils, vents, air ducts, compressor, refrigerant, and fans. These components are responsible for the functioning of your air conditioning system. If any of these components become faulty or fail for any reason, contact an emergency air conditioner repair service provider for urgent assistance. The faster you fix a malfunction, the less damage will occur, and the faster you can get back to properly air-conditioned air.

Vents and Air Ducts

The vents and air ducts are needed to take in and push out air. The take-in vents help remove heat and humidity by pulling in the hot air. The Return vents are needed to return cool air back into your home’s atmosphere. Each vent is typically attached to a channel or air duct. This air duct is responsible for channeling air to and from the air conditioner system in a safe and controlled environment. These components are easy to maintain with the help of an air conditioner repair service provider. Preventive maintenance for air conditioning vents and air ducts typically involves cleaning and replacement of the air filters.

If a hole or opening were to form in your air ducts, your air conditioning system will start to work less efficiently. If you notice weathering around your air conditioning system air ducts or opening, contact your local air conditioner repair service provider. If you live in or around the Charleston, SC, area, contact the staff at Carney & Son 72 Degrees Air Conditioning and Heating for professional air conditioner repair service in the cases of a fault with your air ducts or vents.

Refrigerant & Coils

The refrigerant may be the single most important feature of the air conditioning system. Although other components are needed in order to make the refrigerant work the way it was intended, air conditioning wouldn’t be possible without this special chemical. Refrigerant is a compound that can typically be found in liquid or gas form. The state in which refrigerant is found is completely dependent on the surrounding temperature. Refrigerant has an extremely low boiling point, of around 40° to 50° degrees. This compound can absorb the heat in the air. The intake vents in your air conditioning system, take in the warm air from your home’s atmosphere. As the air passes by the refrigerant, the heat and humidity are absorbed. If your air conditioning system is removing heat and humidity from the air, it could have something to do with these components, contact your local HVAC technician for urgent air conditioner repair service and inspection.

Refrigerant is always in liquid or gas form. The coils are used to contain refrigerant in their gaseous and liquid state. The evaporator coils are used to allow the refrigerant to absorb the heat. The compressor coils compress the vapor refrigerant back into liquid form by compressing it. Once the refrigerant is cooled and compressed it is then sent back through this process in order to remove all heat and humidity from your home’s atmosphere. Things such as refrigerant leaks and compressor failure can cause issues with your air conditioning system’s ability to cool air. If your air conditioning system seems to be leaking a coolant-like liquid or is straining to operate, contact your local heating and air conditioning repair company for urgent air conditioner repair service.


The fans are also an extremely important component of the air conditioning system’s ability to generate cool air. The fans help push air and cultivate cool air to be returned to you via the return vents. If you are having issues with your fans, you may notice the absence of a breeze coming from your air conditioning system. If your fans stop working, it could be due to a connectivity issue, or other problem. Without a fan, your air conditioning system will not be able to force air out or effectively generate cool air. If you recognize the signs of fan failure in your air conditioning system, contact your local air conditioner repair service provider.


The compressor is a mechanical device within the air conditioning system, that moves the refrigerant from the evaporator coils to the compressor coils. This is another important component that could affect the functionality of an air conditioning system if it wasn’t working properly. You may be able to recognize signs of compressor failure by the sound of your air conditioning system, or lack of cool air. If the air coming out of your air conditioning system is still humid or hear a strained mechanical noise coming from your air conditioning system, it could be due to an air conditioning system failure. Contact a local and reputable HVAC repair company for air conditioner repair service and maintenance.

If your air conditioning system is experience malfunction or failure, it could be due to one of the previously mentioned components failing or malfunctioning. In the case of an air conditioning system issue contact a licensed professional to help. If you live in or around the Charleston, SC, area, contact the staff at Carney & Son 72 Degrees Air Conditioning & Heating for professional air conditioner repair service and maintenance.

Where To Go For An AC Repair | Charleston, SC

Do you know that Charleston, SC has a humid subtropical climate? Of course, you did, this means wet, mild winters and hot, humid summers. Summer temperatures are usually in the 90s and can even reach over 100 degrees. When temperatures reach this high, homeowners will make more use of their air conditioners.

When an air conditioner breaks down for any reason life will soon get unbearably hot and sticky causing even more trouble for people with illnesses like asthma, COPD, and allergies, and for those looking after young children or elderly relatives, it is going to get stressful trying to quickly find a reputable AC repair company.

With so many AC repair companies claiming to offer a quality AC repair service, it is not easy to know which one to pick. A reputable AC repair will offer a 24-hour emergency call-out service. It will also have highly trained technicians who are licensed, bonded, and insured, and offer a labor warranty and 100 percent customer satisfaction guaranteed, luckily you’ve found such an AC repair company that is the team at Carney & Son 72 Degrees Air Conditioning and Heating.

The Most Frequent AC Repair Problems in Charleston, SC.

The period running from late spring to the end of summer is when we use our air conditioners the most. It is also the time when they are most likely to break down. Carney & Son 72 Degrees Air Conditioning and Heating will always advise our customers to have their air conditioners regularly serviced during the shoulder seasons to avoid delays or endure any waiting time.

This routine service is the best thing you can do for your unit. It will make sure that everything is working safely. Your air conditioner will also run more efficiently and save you money on energy bills. We also suggest that you schedule your service appointment long before the summer heatwave begins.

This will give you greater peace of mind from the risk of a breakdown and catch any issues before the hot weather begins. Subscribing to regular check-ups, understanding when to schedule an AC repair, and keeping an eye out for any possible problems will help you avoid expensive repairs and long wait times.

  • Icy Evaporator Coils: Warm air from within your home is extracted by a fan and is then blown over the evaporator coils. Coolant within the coils absorbs the heat from the warm air and the cooler air is blown back into your home. Restricting the airflow over the coils will cause the evaporator coils to freeze over. There are several reasons why the airflow could be restricted.


  • Dirty Air Filters: if the air filters are not cleaned or replaced regularly, they will limit the amount of warm air being blown over the coils. Dirty air filters will allow more dirt and other pollutants to enter your home.


  • Coolant leaks: An air conditioner will need an ideal level of coolant in it. A leak will cause this level to drop. Less coolant in the air conditioner will mean less cooling effect from the unit as less heat from the warm air will be absorbed. This will increase the risk of freezing the coil.


  • The Evaporator Coil is Dirty: Dirt has an insulating effect and if the coil is not cleaned it will reduce the amount of heat absorbed by the coolant.


  • Defective fan: An underpowered fan will not blow as much warm air over the coil.

Some of these tasks, like replacing or cleaning the air filters you can do yourself. But a routine service from a technician from Carney & Son 72 Degrees Air Conditioning and Heating cover all the tasks included in your chosen package. Ignoring a problem with your AC whether it be the fan or the evaporator coil will eventually freeze the components of the AC and at the very least you will need to turn the air conditioner off to allow it to thaw. Nor something you want to do on a hot summer’s day!

Low Levels of Coolant & Signs of a Coolant Leak Includes

  • It is important to have the right level of coolant in the air conditioner for it to work efficiently.


  • If you hear hissing sounds, you probably have a coolant leak and need an AC repair.


  • Big energy bills are a result of not having enough coolant in the air conditioner. This means that less heat is absorbed by the evaporator coil. This has a knock-on effect on the rest of the components in your air conditioner. They will need to work harder to keep the correct temperature, and as they work harder, they will use more and more energy, thus increasing your electricity bill.


  • Any component that works harder is going to get hotter, so it is more likely to overheat, burn out, and be replaced.


  • Less coolant will mean less cool air. Without enough coolant, the evaporator coil does not remove as much heat, so the expelled air is warmer.


  • Humidity levels are higher because warmer air will carry more moisture than cooler air., so the air blown back into your home will be humid.

AC Drain Line Troubles

As we have said earlier warmer air contains more moisture than cold air, so the hotter it is the more humid it is. The excess moisture removed from the warm air gathers in the drip pan and then flows outside through the AC drain line.

If the drip pan or drain line becomes blocked for any reason you could experience the following issues

  • Increased humidity in your home – a blocked AC drain, or drip pan will increase the humidity levels in your home.


  • Puddles of water around the air conditioner – a blocked drip pan or drain line will not allow the water to escape your home. The drip pan will fill up and overflow, into your air conditioner and onto your floor.


  • Mold or mildew is growing in the drain line – any smell of mold inside your home could be due to mold growing in the drain line or drip pan. These need to be cleaned regularly.


  • Any blockage could cause the air conditioner to shut down, so it is worth checking to see if the drain is blocked, by dirt or leaves.

Keeping Charleston, SC Cool and Safe.

Having your air conditioner break down during a hot spell will be a very stressful experience. That is why we have highly trained technicians available 24/7. If you need an AC Repair, then please call Carney & Son straight away.

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.

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.
