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.

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.
