How Often and Why Do AC Condenser Coils Need Cleaning?

January 4th, 2022

A properly maintained HVAC system can deliver years of comfortable climate control and healthy indoor air quality in Hawaii. Cleaning AC condenser coils is one of the best ways to keep your AC unit functioning properly. Many home and business owners know the basics of changing air filters and keeping vents clear. However, most of them are unfamiliar with the importance of AC coil cleaning.

This maintenance step provides comfort year-round, avoids costly repairs, and even prevents the need to replace an entire AC unit.

Benefits of Keeping Condenser Coils Clean and Free From Grime

The AC condenser coil exchanges heat for cool air in your home and removes humidity. When dust, dirt, or other debris builds up on the air conditioning coils, it reduces your unit’s efficiency. This can cause higher energy bills, overheating, and even instances of complete breakdown.

AC coils are inside your air conditioning unit and protected from the elements. Nevertheless, they are still exposed to a buildup of dirt, dust, and pet fur that are filtered out of your indoor air. If the evaporator coils are dirty and unmaintained, it will take longer to cool air inside your home.

Regular Air Conditioner Coil Cleaning Schedule​​

An annual coil cleaning is sufficient in most cases, but Hawaii’s humid conditions can cause some air conditioning systems to require more maintenance. It’s essential to consult with a local professional HVAC technician to develop and implement a comprehensive AC maintenance routine.

The location of your AC unit can also affect your cleaning schedule, so you should inspect your coils every couple of months to see if it’s time to get professional AC coil cleaners to give your system a tune-up.

Damage and Malfunction Caused by Dirty AC Condenser Coils

Most homeowners aren’t familiar with the issues that dirty AC coils can cause. Dirty coils can result in a shorter lifespan for your entire HVAC system. Having dirty condenser coils increases strain on other components, which goes beyond daily wear and tear if not addressed. It’s also important to note that older condensers can accumulate dirt and dust more easily than newer AC units, so you should consider replacing your condenser if it’s more than twenty years old.

Coil Fin Sensitivity and How to Avoid Damage

Coil fins are engineered for maximum efficiency and can be easily damaged if improperly cleaned. If you scrub too hard, you can damage them. Also, harsh chemical cleaners can harm their exterior coating. 

Because of their placement in your condenser, it’s best to have them professionally cleaned to avoid damaging the fins or exposing yourself to dangerous chemicals. Without professional help, there is a risk of shock and fire when cleaning AC condenser coils.

HVAC Preventative Maintenance can Save you Money

One of the best ways to avoid frustrating DIY projects, costly repairs, or the need to replace your whole AC unit is to conduct proper preventative maintenance. Professional AC coil cleaning is far more cost-effective than waiting for a malfunction that needs immediate repair. 

Routine maintenance performed by a licensed HVAC professional pays for itself when you consider your energy bill savings and the performance aspects delivered by a properly maintained unit. Additionally, clean AC coils will help keep your ducts, vents, and other components of your AC system working at peak performance in every season and climate.
