The Value of Cleaning Your AC Condenser Coils


Your air conditioner is a reliable workhorse that functions for you throughout the summer to keep you as cool and comfortable as possible. An essential part of the air conditioning unit is the condenser coil system. The condenser coils have the critical job of releasing hot air out of the air conditioning unit and into the air. For this reason, they are part of the outdoor unit of your air conditioner, leaving it vulnerable to weather elements to accumulate dirt, dust, and debris. When your unit gets covered with these elements, your heat cannot escape the condenser coil, and the heat process is blocked. Therefore, coil cleaning should be a part of regular maintenance.

AC Coil Maintenance

Why Is AC Condenser Coil Maintenance So Important?

If you rarely or have never cleaned your AC condenser coils, your air conditioner will use more energy while also reducing its ability to cool your home. Failure to clean your air conditioning coils drives up your energy bills. In other words, you’ll be paying more for a unit that is doing less.

If your air conditioner condenser coil malfunctions or is full of residue, then the entire system will be affected. Residue can impede the efficiency of your air conditioner. Cleaning your AC condenser coil and regular maintenance are the best ways to extend the life of your air conditioner.

How Often Should You Clean AC Condenser Coils?

Your outside condenser coil should be cleaned at least once a year, especially here in the Westwood area, where we rely on our air conditioners for months at a time. Fortunately, condenser coil cleaning is a standard part of air conditioner preventive maintenance at Suburban HVAC, so if you’re taking good care of your unit, an HVAC technician will perform this task for you.

How to Prevent Dirty Coils

Because condenser coils can easily be bent, it is recommended to leave the coil cleaning to an expert. This is something that is performed during routine maintenance.

Between visits, you can periodically look at your outdoor unit from time to time. To clean the outdoor unit, remove any debris from around the unit, and make sure that the surrounding areas are clear. Trim away any foliage that might find its way into the unit or restrict adequate airflow. Try to keep a two-foot area around the area free of any obstructions.

During your routine maintenance visit, your Suburban technician will also straighten out any of the condenser’s fins that may have bent from the weather elements. Bent fins can limit airflow, so adjusting them can help maximize the efficiency of your condensing unit.
