Why Do I Need an AC Coil Cleaning?

With warmer temperatures upon us, there’s no better time to gain some knowledge of your air conditioning system, starting from the inside out! Knowing just a few details about how your commercial HVAC system works can help you decide what to do when it’s not working like it should.

So, first we need to understand what air conditioner coils are and what they do!

What Are Air Conditioner Coils?

There are two types of air conditioning coils which make your system work: evaporator coils and condenser coils.

What’s an Evaporator Coil?

An air conditioning system’s evaporator coils are the indoor air-cooling coils which removes heat from the space, creating a comfortable environment we know and love!

What are Condenser Coils?

The condenser coils are another vital part of your air conditioning system. These coils pull heat from the inside of your building, then exhaust it outside.

What Happens if Air Conditioner Coils Aren’t Cleaned?

Dirty evaporator and condenser coils make up the bulk of the service calls we receive. When neglected, these maintenance needs can become costly and cause damage to your air conditioning system.

Evaporator Coil Maintenance

When evaporator coils become dirty or clogged, the system, the coil will freeze up.  This will not allow air flow across the coil. A service technician will need to turn off to allow coil to defrost, chemically cleaned and perform a full operations check on the system.

Stored maintenance practices can help alleviate issues with your system’s evaporator coil, and regular filter and belt replacements are essential to your system.

Evaporator coils, with proper filter changes and coil brush downs during maintenance should only require chemical cleanings every 5-7 years, depending on run time and other variables, such as construction or particles or solvents in the air.



Air-Cooled Condenser Coil Maintenance

When your condenser coil becomes dirty or clogged, it will take your air conditioning system longer to bring the temperature down, costing you more money to get comfortable. If left unattended, the condenser coil will not allow air flow across coil, which will cause system to shut down on high pressure safety control. This will require a service technician to perform a chemical power washing to remove the dirt that accumulates in the coils to allow airflow through the coil, and perform a full operations check on the system.

Standard air-cooled condenser coils should be chemically power washed at least once a year in the Spring.

More frequent cleanings may be necessary if excessive dirt in the air gets trapped in the coils from construction or traffic.
