How the Evaporator Coils in Your AC System Might Be the Reason Your System is Not Running Properly

A central air conditioning unit contains many important parts, including the evaporator coils, which are located inside the indoor part of your system. If these coils are not working properly, you may experience problems with your air conditioning system. Here are three things you should know about the evaporator coils in your AC system.

The Purpose of the Coils

The evaporator coils are typically located behind a panel or door on your AC system. These coils are there for one main purpose, which is to catch the heat your AC system removes from your home.

When you run your AC system, the system will pull air from inside your home, and this air will run through the coils. The coils are able to extract the heat from the air with the help of the coolant, which continuously circulates through the coils when the system is on. The system will then send the cooled air back into the home and the hot air outside. If something disrupts this process, you may experience trouble cooling your house.

Issues That Prevent the Evaporator Coils From Working

There are several different things that can stop the coils from completing this job. The first thing involves dirt. As you use the system, the coils can become dirty with dust and debris. When this occurs, the coils are not able to work as efficiently, which means your AC system may run more than it should to try to keep your house as cool as you would like.

Cleaning the coils with a wire brush is a great way to solve this problem. Another good step to take is replacing the furnace filter on a regular basis. Most experts will tell you to replace your air filter at least once every three months; however, you may need to replace yours more often depending on how much you use your system.

A second problem that can occur with the evaporator coils is freezing. Because there is coolant circulating through the coils, the coils tend to get really cold. When this mixes with the condensation produced during the process, the result can be frozen coils. Here are three of the main reasons coils freeze up:

  1. The coolant level in the system is low. Without enough coolant, the system is unable to absorb the heat from your home. When the coolant level is low and heat cannot escape, condensation builds up and causes the cold evaporator coils to freeze.
  2. The fan blower in the system is not working properly. If the fan is not working properly, the system may have a hard time pushing the cold air into the home. This will trap the air in the system, and it may leave the coils colder than usual.
  3. There is something restricting the airflow in the system. The coils will freeze up if something gets trapped inside your device. This could be dirt, bugs, rodents, or other types of debris.

When the coils freeze up, you will be able to see ice on them, which makes this problem easy to detect. Frozen coils can cause your AC system to run inefficiently, and they can also cause the system to stop running completely. To fix this problem, you will need to hire a company that offers air conditioning repair.

Living without a good-working AC system in the summer can make life miserable. If your system is not working as well as it should be, or if your system is not working at all, you should call an air conditioning repair company, such as C B Lucas Heating & Air Conditioning, to schedule an appointment for them to diagnose and fix your system today.
