What Causes an HVAC Evaporator Coil to Leak? 


If your evaporator coil is corroded and leaking, you will notice your AC is less efficient, taking longer to cool the air. You may also need to top off the refrigerant more often. Either way, you should contact our reliable HVAC techs to inspect your unit, pinpoint what’s causing the problem and perform necessary repairs.

Corrosion: Corrosion occurs when formic acid accumulates on the coil due to the interaction of moisture, copper and volatile organic compounds in your indoor air. One way to avoid coil leaks is to reduce the VOCs you use in your household, such as by switching to all-natural cleaning products.

Mold buildup: Mold and biofilms can also damage your evaporator coil, eroding the copper’s integrity.

Vibrations: If you have an older AC unit, its vibrations can cause the aluminum fins to punch holes in the copper tubing.
