If you notice your AC’s condensate pan overflowing, you should immediately get it inspected. Mold, corrosion, or damage to the air conditioner’s electrical components are a result of an overflowing condensate pan.
To prevent an overflowing condensate pan, it’s important to understand why it happens. Trusted heating and cooling services provider W.E. Beavers Jr. Heating & Cooling discusses three common reasons why an AC condensate pan overflows.
1. Clogged Drain Line
Algae and other mineral deposits may accumulate in the drain line due to a constant flow of water from the condensate pan. The accumulation of these deposits will eventually restrict the flow of water, causing it to back up and overflow into the drip pan. Flushing the buildup with a pipe-cleaning solution can resolve the problem.
2. Excessive Flow
Excessive condensate can be drained through the drain line. However, if there has already been a significant accumulation of condensation, it affects the rate at which the line is draining condensate — which can result in an overflow.
Typically, condensate pans are designed with a floater, which shuts the system off before the pan overflows. To reset the floater switch and address any issues that led to the overflow, make sure to contact a trusted cooling and heating services provider.
3. Broken Condensate Pump
It’s normal for there to be a small amount of water in the AC drip pan. The warm air that passes over the chilly coils causes the moisture vapor to condense into water, which then flows through a small pipe and into the drip pan. When it comes into contact with water, the condensate pump will typically start to operate. But if the condensate pump fails, water will spill out instead. Fortunately, condensate pumps are easy to replace. Call your trusted technician to help you fix the component.
