Quick Repair Solutions for Your Leaky Air Conditioner

Most AC repair service calls that we receive are related to leaky units. We’re always happy to take care of any issue a client has, but in the interest of saving money, we’d also like to offer some insight on what causes leaks in your HVAC system and how to address the problem.

Check Your Overflow Pan

A major cause for a leaky AC unit is an issue with the overflow pan. The overflow pan catches condensation and guides it down the condensate line to the drain. However, if you notice a leak, it could mean that the pan is cracked or damaged. While small holes can be repaired with epoxy glue, it is best to have an AC technician come out to replace the overflow pan if it’s significantly damaged.

Unclog or Change Your Filter

Your AC filter should be changed once a month or every other month to keep it working its best. If your home is subject to excess dust or pet hair, it should be changed even more frequently. Otherwise, clogs can occur that will result in ice forming on the evaporator coils. When the ice melts, you will end up with a leaky AC. Be sure to check your filter frequently during the cooling season to prevent unnecessary leaks.

Clean out the Condensate Line

A clogged condensate line is one of the most common culprits for leaks. The condensate line is responsible for draining condensation away from the overflow pan. If dust and other debris build up within the line, the moisture will get backed up into the overflow pan, resulting in an overflow. If your unit is equipped with a sensor that detects water overflow, it will automatically shut down the system. If your AC unit is shutting itself off or leaking, check the condensate line first to make sure there are no clogs.

Of course, some repairs require professional analysis and completion. Anything beyond a minor leak could have more serious issues to blame, like:

  • Improper installation – if the original installation was not done properly, that can lead to leaks due to unevenness, incorrect pressures, and more.
  • Fault air seals – when the sealant around your air conditioner isn’t tight, warm air can seep in and create condensation within the unit.
