Why is my AC drain pan overflowing?

An AC drain pan usually overflows because the condensate drain line is clogged with dirt, algae, mold, or other debris, preventing condensation from draining properly.

Can mold or algae grow inside an AC drain line?

Yes, mold, algae, and other organic buildup can grow inside an AC drain line because it is a damp environment where moisture collects during normal air conditioning operation. Over time, this buildup can clog the drain line, cause the drain pan to overflow, reduce HVAC efficiency, and potentially lead to water damage if left untreated.

What causes an AC drain line to become clogged?

An AC drain line can become clogged when dirt, dust, mold, algae, sludge, or other debris accumulates inside the condensate line over time, restricting the flow of water. Dirty air filters, inadequate air conditioning cleaning, high humidity, and a lack of routine HVAC maintenance can also contribute to blockages and cause the drain pan to overflow or lead to water damage.
