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.

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.

Air Conditioning And Heating Service: What You Need To Know About Heating And Air Conditioning Units | Charleston, SC

According to the U.S. Department of Housing and Urban Development, 84 percent of all homes in the United States have some air conditioning. We live in the modern age of technology, where everything has been created for our convenience and comfort. As a result, our homes, offices, shops, and other places where we spend much of our time are fitted with heating, ventilation, and air conditioning systems, commonly known as HVAC systems. These unique temperature-controlled systems create comfortable working and living environments and are serviced by an air conditioning and heating service.

What Are the Components of an HVAC System?

An HVAC system is one of the most complicated and sophisticated systems you can have in your home or working places. As such, should a breakdown occur, only an experienced and certified air conditioning and heating service maintenance company like Carney & Son 72 Degrees Heating & AC service should handle its inspection, maintenance, and repairs. Some of the parts prone to wear and tear and which may need routine replacement and maintenance include:

Air Return

This is the starting point of the ventilation system of the HVAC system. It sucks the air, draws it through a filter before it passes it into the central system. Ensure that you or an air conditioning and heating service dusts the air return regularly since the debris and dust that piles up over time can quickly build up on your filters and cause massive damage.

The Filter

The filter is the second part of the air return unit. Filters need routine replacement to guarantee optimal performance. Depending on the manufacturer's manual, have the filters changed by a professional air conditioning and heating service as regularly as possible.

The Ducts

These are the channels that provide the passage of heated or cooled air. It is recommended that you have an air conditioning and heating service professional clean your ducts every two years to sustain a good working condition of your heating and air conditioning system.

The Exhaust Outlets

An exhaust vent in the system expels all the utilized air. Ensure that you consult an air conditioning and heating service to check on your vent stack or chimney flue at least once a year and tune it up when necessary.

Electrical Fittings

This part ensures your system is supplied with adequate amounts of power for uninterrupted performance. Problems associated with heating and air conditioning systems often originate here. If your system stops working, check for expired batteries in your thermostat or a tripped breaker.

Outdoor Unit

This is the main part of the system you are likely to consider when an HVAC system is mentioned. It holds the fan, which aids airflow. Always ensure that you keep your unit clear of vegetation and debris since it can cause severe problems if your fan sucks in.


Being part of the outdoor unit, the compressor is capable of transforming refrigerant from gas to fluid before sending it to the coils. Therefore, inspect your compressor regularly since many system malfunctions originate from this point.


The coil is another integral part of the outdoor unit, which chills the air as it flows through. Inspect the coil frequently to ensure it is in good working condition. If you realize they are freezing up, you should adjust refrigerant levels and the filter.


The blower pulls in warm air through the central section of the unit. Ensure the air progresses through this part efficiently to enhance the durability of your heating and air conditioning system.

What Are the Most Common Problems that Occur in HVAC Systems?

Owing to their structural complexity, heating and air conditioning systems harbor particular problems that may occur in their lifetime. Most of these problems can be resolved by our highly trained and experienced professionals at Carney & Son 72 Degrees heating and AC service. The following are some of the most common issues that tend to occur in the heating and air conditioning systems:

Filter Blockage

Filters can get clogged because of the dirt that accumulates after several months of usage. When this problem occurs, filters need to be cleaned or changed for your system to work optimally.

Faulty Thermostats

This is a major problem that you should be prepared to face if you have a heating and AC system at your home or office. A thermostat is regarded as the heart of the system. If the thermostat has an issue, then the whole operation of the HVAC system is entirely stalled.

If your thermostat is an older version, then you should think of replacing it with a new digital one. If you have a modern digital thermostat and that still fails to function as intended, check if batteries have become weak and replace them. If this malfunction persists, then there might be a different problem that requires a professional's touch. Call Carney & Son 72 Degrees heating and AC service to fix the problem.

Clogged Drain

Each heating and air conditioning system has a drainage system with a drain pan that collects the excess moisture drained out by a drain pipe. With time, this drainage system is blocked by dirt and impurities. If this blockage is not addressed early enough, the drain can expel the moisture on undesired areas of the unit and jeopardize its functioning.

Leakage of the Refrigerant

The refrigerant is a liquid that cools the air in the system to provide cool temperatures. The refrigerant may produce a leakage characterized by a sharp pungent smell. This leakage can damage other sensitive parts of the HVAC unit. Turn off your heating and air conditioning system as soon as you notice this leakage and consult a skilled air conditioning and heating service.

Failure of the Furnace to Heat up

The furnace is the primary heat-generating source of the heating and air conditioning system often fails to heat up. If this occurs, the entire room lacks heat, causing a freezing temperature. Sometimes the furnace fails to heat up as a result of the pilot light being off. If you cannot easily detect the cause of the failure, call Carney & Son 72 Degrees Heating & AC service for professional help with your air conditioning and heating service needs.

Creaking Noises

The HVAC system experiencing mechanical hitches produces weird sounds when it is turned on. The blower fan or any other structural component of the system could be faulty. To avoid further mechanical problems, act swiftly and engage a professional from Carney & Son 72 Degrees heating and AC service to fix it for you.

Air Conditioning And Heating Service: How To Tell When It's Time to Replace Your Air Conditioner | Charleston, SC

For any Charleston, SC homeowner it is a tough decision on when to replace your air conditioner. In fact, due to the high cost of an AC unit, it is one of the toughest decisions you will face as a homeowner. A new air conditioner is a huge investment. Homeowners must decide whether or not to keep repairing older inefficient AC units or to replace them with a newer more energy-efficient model. Today's Air Conditioning and Heating service companies offer an array of high-efficiency models.

Deciding when to replace your air conditioner is not an easy task. Carney & Son 72 Degrees Air Conditioning and Heating of Charleston, SC has you covered with this advice on when it might be time to call an HVAC service for air conditioner replacement. Below are some of the most tell-tale signs that you need a new air conditioner.

Your Air Conditioner Is More Than 10 Years Old

Most air conditioning units were designed to last ten to twelve years. That is only if they are well maintained with AC tune-ups every year and well cared for. Units that do not see regular maintenance will not last as long. It is vital that you do tune-ups every year on your air conditioning unit if you want to see the full life span of your unit. Some well-maintained units can last longer than twelve years but this is not the norm. If your air conditioner is needing constant repairs and your unit is ten-plus years old, it might be time to call Carney & Son 72 Degrees Air Conditioning and Heating for a new unit. This is even more true when you consider the advancements in energy efficiency in the last five years alone with central air conditioners. Older unit parts are more costly to replace than newer units is another factor to consider here with an aging unit.

Your Air Conditioner Uses Freon

If your air conditioner uses Freon, chances are it is using R-22 Freon. R-22 Freon production has been phased out by the United States federal government as of January 1st, 2020. You can still have Freon added to your air conditioner when needed, but it is now extremely costly to do so. Add on to that the cost of repairs and you might well have your answer about when it's time to make that call to an Air conditioning and heating service. If your older AC unit uses freon you will eventually need to replace it with a unit that uses the newer R410A refrigerant. You can even use a Heat Pump to go even greener. Despite the name Heat Pump, it actually will cool your home. Basically, if your unit still uses Freon it is time to consider making that call to an air conditioning and heating service for a new unit replacement.

Your Air Conditioner Is Energy Inefficient

If your air conditioner has a low SEER Rating it will cost you a lot of money to operate every year. The SEER rating, also known as the seasonal energy efficiency ratio, has a minimum standard SEER rating of 13 for AC units. The maximum efficiency for AC units is a SEER of 21 SEER. The size of your AC unit along with the size of your home will also determine the efficiency of your system. Your ductwork even comes into play for the efficiency of your system. If your air conditioner's SEER rating is below 14 you are paying a lot of extra money to the utility company every year just running your AC unit. We recommend that our customers seek out SEER 20 or 21 models for maximum energy efficiency. If your AC unit has a SEER of 13 or below it is not an energy-efficient model and should be replaced with a newer model. You can always call your local Air conditioning and heating service if you are unsure of your unit's SEER rating.

Extensive and Expensive Repairs

If your air conditioner is facing a rather expensive repair, you might consider making that call to an Air conditioning and heating service such as Carney & Son 72 Degrees Air Conditioning and Heating. Simply weigh the costs of the heavy repairs against the cost of a new unit. Also factor in the current unit cost per year to operate based on its maximum efficiency. Keep in mind its maximum efficiency will only be at its maximum if you provide yearly maintenance such as an AC tune-up every year. Now weigh the two costs together and determine what the best path forward for you is. If you have multiple signs on this list of tell-tale signs then it is definitely time to make that call to an air conditioning and heating service.

Frequent Breakdowns

Is your air conditioner breaking down often? Are you constantly calling up an Air conditioning and heating service to make expensive air conditioner repairs? Are you calling Carney & Son 72 Degrees Air Conditioning and Heating to often address ever-mounting problems with your air conditioner? Repair costs will quickly add up, so if you are experiencing frequent AC repairs, it might be more worth your money to invest in a new air conditioner. You might save money in the long run by simply replacing the old unit with a high-energy efficient unit.

Your Home Is No Longer Comfortable

Does it seem as if you can never keep your home cool anymore? Your AC may be failing and only a matter of time before it breaks down completely. There is also the chance that your air conditioner size is the wrong size for your home and ductwork. You need your AC unit to do its job and cool down the house. If your air conditioner is no longer cooling the home it may be time to make the call to an Air conditioning and heating service in Charleston, SC such as Carney & Son 72 Degrees Air Conditioning and Heating service.

If you have any of the signs on this list you may want to consider investing in a new AC system. Carney & Son 72 Degrees Air Conditioning and Heating can replace your aging AC unit with ease. Call us today for a quote.
