How to Clean Your Air Conditioner’s Condenser Coils

With summer in full swing, it’s likely that your central AC could use a little TLC. Many of our clients would like to perform routine maintenance on their AC units, but are unsure of what to leave to the professionals. While we recommend professional attention for most of your HVAC needs, one task homeowners can do to keep the AC running effectively is a spot cleaning of the unit’s condenser coils. Read on for information and advice on tackling this task.

What Are Condenser Coils?

Condenser coils are essential to your central AC’s operation. They are located in the outdoor unit of the system, and they facilitate the transfer of heat from your indoor environment to the outdoors. But when they are coated with dirt or dust, they cannot do this as efficiently. Regular cleaning, at least once a year but preferably more often, will maximize the effectiveness of your condenser coils. By extension, this will prolong the lifespan of your AC system. In turn, your energy bill and overall energy usage will be lower, as will the need for repairs and replacements.

The Right Time to Clean Condenser Coils

Summer presents the right opportunity to clean your condenser coils. The environmental burden on your outdoor unit is higher than ever in the summer, as debris and dirt will be in the air due to frequent lawn mowing and more construction projects. If your outdoor unit is in close proximity to traffic in your neighborhood, it is exposed to even more dust and debris.

How to Clean Your Condenser Coils

While a thorough cleaning of your condenser coils should always be performed by a professional, it is a good idea to perform basic maintenance to ensure smooth operation between deep cleanings.

  • Turn your unit off. Never attempt to do any maintenance on an HVAC system without taking this crucial first step, to prevent harm to both yourself and the unit.
  • Visually inspect the condenser coils.
  • Remove any large debris, such as leaves or garbage that may have blown onto the unit.
  • Use a broom to sweep away grass cuttings or other debris near the bottom of the unit.
  • Cut back any bushes that may be growing too close to the unit.

These simple steps will ensure that your condenser coils can work as efficiently as possible between professional cleanings. To schedule a cleaning and ensure that your system stays in tip-top shape this summer, contact us using the form below.
