In the summer, air conditioners suck hot air from inside of your house through a series of cooling coils, called Condenser Coils. The coils turn the warm air into cool air using a freezing agent (Freon). The cold of the coil causes water to collect (condensation) on the outside of these coils, much like a glass of ice water will “sweat.” This condensation is then collected in a pan located just beneath the coils, which drips into a line (the Condensate Line or “CLine” for this article). The CLine is designed to process the water overflow, directing it to an outer part of the house.
If your AC unit is on top of your roof, your CLine will drain onto the roof. If your AC unit is in an attic, the CLine is located in the attic as well. Often, what happens is the Catch Pan and/or the CLine grows algae, just like a pool or any other standing water. This will clog and eventually cause the Catch Pan or CLine to overflow and/or not flow properly. Two easy ways to prevent overflow:
Clean the pan and CLine regularly (or at least at the beginning of the summer season).
Install an EZ-trap or a rubber float switch that shuts the AC unit off once the CLine is full to a certain point. These should be installed by a professional.
