When you turn on your air conditioning system, it uses a number of different components to remove the heat from inside your home. The evaporator coil is one of the most important parts of the whole system and there are a number of common things that can go wrong with it. We wanted to put together a quick explanation of what the evaporator coils do and what some of the common problems it may have. If you’re experiencing any of the issues below, don’t hesitate to call Air Conditioning Experts for air conditioning repair in Atlanta.
How Evaporator Coils Work
In order to lower the temperature of your home’s air, your AC has to remove heat and exhaust it outside. To accomplish that, your air conditioner circulates a compressed refrigerant between two series of coils: the evaporator coils (which are located in the inside unit of your AC system) and the condensing coils (located in the outdoor unit).
The evaporator coils get very cold and a large fan in the indoor unit pulls in warm, moist air from your home and passes it over the cold coils. The refrigerant in the coils absorbs the heat from the air and then get circulated to the outdoor condensing coils where that heat is exhausted. The newly-cooled air continues past the coils, into your ducts and then into your home.
Evaporator Coil Problems
Here are a few common issues that could happen to your evaporator coils. If you’re experiencing any of these issues, call for air conditioning repair in Atlanta.
- Dirt and dust – All of the air that travels into your home during cooling season has to pass over the evaporator coils. Any dirt or dust that is in the air can get caught on the evaporator coils, which prevents them from cooling effectively.
- Moisture – If you’ve ever taken a cold glass outside on a hot day then you’ve had experience with condensation as water starts to collect on the glass. The same thing happens when the warm air from your home passes over the cold evaporator coils. This moisture can attract dirt, dust, bacteria and even sometimes mold if it is not properly drained.
- Freezing – What causes your evaporator coils to freeze? It could be that you have low refrigerant in your system. But it could also be that the flow of air over the coils is insufficient. This can be caused by a clogged air filter or if the fan motor isn’t working well. Frozen coils can cause inadequate cooling and put extra strain on your system. If it is severe enough, it can prevent your AC from working at all.
