Stay Cool With A Clean AC Evaporator Coil

AC Evaporator Coil
How A Clean Evaporator Coil Benefits You

The evaporator coil is an essential part of any air conditioning unit. The evaporator coil is found inside a metal compartment attached to the unit or is found inside the air handler or AC unit itself. It consists of several copper tubes, through which the compressor pumps cooled refrigerant. As the blower forces warm air over the coil, the refrigerant draws heat from the air and dissipates the heat through the outdoor condenser unit.

This article explains the effects of a dirty evaporator coil and what you can do to improve its function.

The Effects of a Dirty Evaporator Coil

Allowing dirt and debris to collect on the evaporator coil could lead to clogs in the condensate drain that removes moisture from the AC unit. A clogged drain can result in leaks and expensive water damage.

You may also experience a reduction in air quality, as a dirty evaporator coil can cause dust and other pollutants to circulate through the AC unit and out the vents. It could also harbor harmful bacteria and pathogens.

Most of all, a dirty evaporator coil prevents the air from cooling. A layer of dirt and debris on the coil acts as insulation, preventing the refrigerant from drawing heat from the air. As a result, your home will not get as cool as it should. Instead, it will be uncomfortably warm and humid. Plus, your AC unit will have to work much harder to bring the temperature down, causing your electric bill to skyrocket.

Cleaning Your Evaporator Coil

In maintaining your AC unit, there are some items you can “do-it-yourself,” but cleaning the evaporator coil is not one of them. A quick online search will result in videos and articles describing how to clean the evaporator coil, as well as products specifically designed for the job. But cleaning the evaporator coil yourself can be harmful to the unit and even dangerous for you. Evaporator coils are filled with refrigerant, which is toxic and corrosive. In fact, you must have a license to handle refrigerant, so it’s best to let the professionals deal with it.

Fiddling with the evaporator coil compartment may void any warranties you have on the AC unit. By attempting to disassemble and clean the coil yourself, you could damage the parts beyond repair, and they are expensive to replace. Most HVAC companies are happy to send a certified technician to your home to diagnose and repair your AC for you.
