Professional Evaporator Coil Cleaning 

AC coils are an important part of how an HVAC system operates. The air conditioner uses fans to blow air over the evaporator coils, which cools down the air using refrigerant. The refrigerant is inside the coils. When the AC coils are dirty, the air conditioner can not efficiently perform its job. 

One of the reasons why evaporator coils get dirty is because the air filters have not been changed often enough. Air filters remove particles of dust and other airborne contaminants from the air before it gets sucked into the air conditioner. Homeowners should be changing out their air filters every one to three months. 

Grime can build up on the AC evaporator coils over time, leading to inefficient performance. This blog post discusses three warning signs of dirty evaporator coils that need to be cleaned. Coil cleaning can be performed during bi-annual HVAC maintenance appointments or more often if needed. 

A Loss of Cooling Function

coolingOne of the first signs of a malfunctioning air conditioner that homeowners notice is a loss of cooling function. When the air conditioner coils are dirty, they can not efficiently cool the air. This means that the air conditioner may not be able to cool the home to the desired temperature, even if it is constantly running. 

Cleaning the AC coils can instantly improve the function of the air conditioner. The HVAC technician will remove the air conditioner, clean the coils with soapy water and a towel, and then reassemble the unit. Afterward, the air conditioner should be able to quickly and efficiently cool the home to the perfect temperature. 

Frost On the Air Conditioner

coilOne of the things that can happen if the inside of the air conditioner gets too dirty is frozen evaporator coils. A layer of grime and dust on the AC coils can interrupt the heating and cooling process that the air conditioner usually goes through. Because the coils are too dirty to cool efficiently, the moisture from the air freezes to the surface of the coils and forms frost. 

It is important for homeowners not to ignore signs of frozen evaporator coils. The coils can become corroded by the moisture if left frozen for too long. Tiny pinholes can begin to form in the metal due to prolonged exposure to corrosive materials from the grime and frost. 

Longer Cycles

Because the air conditioner can not produce enough cold air to lower the home's temperature, it may have to run for longer cycles at a time. Homeowners may notice that the air conditioner is always running but never seems to hit the ideal temperature. 

Cleaning the air conditioner coils can help improve the unit's performance so that it can reach the desired temperature in a normal amount of time. Longer cycles also mean more energy spent and higher utility bills. Keeping AC coils clean is an important part of HVAC maintenance for homeowners.
