Common Reasons Why an AC’s Condensate Pan Is Overflowing

Algae and minerals can clog the condensate drain, causing water to overflow. Flushing with a cleaning solution clears the buildup.

When an AC’s condensate pan overflows, it should be inspected immediately. An overflowing condensate pan can lead to mold, corrosion, or damage to the air conditioner’s electrical components.

Understanding the reasons behind an overflowing condensate pan is crucial for prevention.

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.

Excessive Flow

Excessive condensate can be drained through the drain line. But, if there has already been a considerable accumulation of condensation, it affects the rate at which the line is draining condensate, potentially resulting in an overflow.

Typically, condensate pans are designed with a floater, which turns the system off before the pan overflows. Contact a trusted cooling and heating services provider to reset the floater switch and solve any issues that led to the overflow.

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 a trusted technician to fix the component properly.
