Air ConditioningWhy Is a Dirty Evaporator Coil a Problem?

The summer season here in Washington is certainly not as hot and intense as, say, that in Arizona. That does not mean that you can afford to put the operational quality of your air conditioning system at risk, though. There are a number of things that can go wrong with even the best air conditioning systems on the market. Far too often, we find that the repairs that we are doing could have been avoided had the homeowner taken earlier action. Today we’ll talk about why the evaporator coil must be clean, and how you can spot some warning signs that will help you to avoid the need for AC repairs in Everett, WA.

What Does the Evaporator Coil Do, and Why Must It Be Kept Clean?

The evaporator coil is very aptly named, as this is the point in your air conditioning system where refrigerant is evaporated. An air conditioner does not manufacture cool air, but instead removes the existing heat in the air in your home. This is completed via the refrigerant cycle, specifically in the evaporation of refrigerant as it absorbs heat from the air surrounding this coil.

If the evaporator coil is very dirty, then it is not going to be able to successfully absorb that heat. This can lead to a number of different problems. Best case scenario, your system is going to struggle to cool your home effectively, and will operate less efficiently as a result. However, a dirty evaporator coil can also ice over, as it gets too cold and the condensation on it freezes up. This can cause damage to the system, and even to your home, as ice melts and can cause water damage.

If you suspect that your coil or any other part of your AC is in trouble, give G & S Heating Cooling & Electric a call right away.
