3 Signs That It’s Time to Clean the Evaporator Coil

The Importance of Professional Evaporator Coil Cleaning 

After a summer like this one, it’s easy to see how much work the air conditioner puts in. Sure it gets a few months off in the winter, but it makes up for it when the temperatures rise. All that hard work can take a toll on the air conditioner that requires some maintenance occasionally to ensure it is always operating at peak efficiency. One of the most important steps of seasonal AC maintenance is evaporator coil cleaning. The evaporator coil is the workhorse of the air conditioner; when it is compromised, the entire system can suffer.  

In contrast to the consequences of a dirty evaporator coil, there are some clear benefits of getting it cleaned as a part of a maintenance plan. Among the benefits of AC coil cleaning are:

  • Lower utility bills
  • Shorter cooling cycles
  • More comfortable home

Here are three major signs that an evaporator coil cleaning is overdue. 

Loss of Cooling Function cooling

An air conditioner works by allowing a chemical called a refrigerant to boil or evaporate. This process causes the refrigerant to become very cold quickly. This process occurs in the evaporator coil inside the air conditioner as warm air is blown through it. The result is that the warm air becomes cool by giving its heat to the evaporated, cold refrigerant. 

When this process is impeded, the air conditioner can lose cooling power. The most common way this happens is by blocking airflow from a dirty coil. Thus, cleaning coils can restore cooling power to an air conditioner. 



Frost and Frozen Coils

An air conditioner is a finely-tuned machine. Refrigerants must be kept at specific pressures, and airflow must be kept unimpeded, or the whole system can suffer. The goal of the evaporator coil is to get as close to freezing temperatures as possible to stay efficient without freezing. 

However, when evaporator coils are dirty, airflow is impeded and can’t keep the coils above freezing. Instead of removing moisture from the air and draining away the resulting condensation, the moisture will freeze to the coil instead. This compounds the airflow problems, and frost on the coil will lead to a frozen evaporator coil. 

Longer Cycles to Cool the Home 

The air conditioner is one of the biggest energy hogs in the home, so it makes sense to spend some time and energy keeping it efficient. When evaporator coils are dirty and frozen evaporator coils are a consistent problem, the air conditioner loses efficiency and can’t keep the home cool like it once did. Energy bills will spike because the air conditioner must use longer cycles to cool the house. 

Simply schedule evaporator coil cleaning and routine maintenance from a reliable AC maintenance contractor to restore lost cooling power. In a quick visit, technicians can restore lost cooling power and save homeowners money. While most homeowners try to get this done in the spring, it is never too late to clean the coils, especially if a home is heated and cooled by heat pumps.
