How Dirty AC Coils Affect Your Cooling

Wondering why your air conditioner is not operating very efficiently in the middle of the summer? There could be a number of reasons for low efficiency and poor performance from your cooling system, but one of the most common is actually something that’s relatively easy to fix. Learn about how dirty AC coils make your air conditioner run less efficiently—and what these coils are meant to do—below.

Why Clean Coils Are So Important

Your air conditioner cools your home by heat exchange. It absorbs heat from the air in your home using a chemical blend called refrigerant. This refrigerant evaporates indoors and absorbs heat from the home—but then it needs somewhere to go.

The condenser coil outdoors is where refrigerant releases heat into the air around the system. As refrigerant condenses (turns from a gas to a liquid) it’s able to release heat with the help of a very large fan and carefully engineered fins. But it can only effectively and efficiently release heat if the coils are clean.

Dirty Condenser Coils

When the condenser coils are dirty, you may come across a number of issues with your AC system. Heat cannot effectively release from the system, which means:

  • Other components may become overworked and break down.
  • Efficiency is lowered.
  • The air conditioner may not cool your home completely.

Clean Coils Regularly

So what can you do to ensure your outdoor coils stay as clean as possible? For one thing, we recommend clearing away large debris and shrubbery from the outside unit.

In addition, schedule maintenance once a year with professional technicians. You may be able to clean off the coils yourself, but we highly recommend professional service so that your entire system gets inspected and in shape for the summer. And when you notice a cooling issue, call a technician ASAP!
