The condensate drain pan in your Birmingham, AL heating and cooling system allows moisture to exit the equipment and your home. A properly functioning condensate drain pan protects your HVAC equipment and your home from water damage. Know how your condensate pan works and when to call KS Services for help.

How a Condensate Drain Pan Works

During operation, heating and cooling equipment generate condensation. As your AC extracts moisture from indoor air, condensation forms. This is as a result of heat transfer. The condensate drain pan’s purpose is to collect this water as it drips from your air conditioner’s evaporator coils.

The condensate pan is attached below the evaporator coils. It must be correctly fitted to catch moisture without leaks. Moisture flows to the condensate drain line and out of your home.

Condensate Drain Pan Problems

Problems with condensate drain pans often cause a water leak within HVAC equipment and water damage in the home. If you have regular AC tune ups with KS Services, our technicians inspect your system’s condensate pan. They look for issues such as:


If not correctly fitted within the system, water leaks outside the air conditioner. This leads to water damage to the surrounding area if the issue is ignored.


Due to the moist environment, mold and mildew may grow. These contaminants, as well as particles in the air, clog the drain pan. This stops the flow of moisture to the drain line and out of the home.

Moisture backup results. Depending on the orientation of your HVAC equipment, water backs up into the system. This leads to component damage. In this case, water also spills over the edges of the condensate drain pan and damages the area around your HVAC system.

Don’t risk water damage and mold. These are often expensive restoration projects.


Your condensate drain pan experiences wear and tear just like other HVAC components. Damage allows water to leak. An obvious sign of a damaged drain pan is water or water damage around your HVAC unit.
