The primary function of your air conditioner’s condensate pan is to collect dripping condensation and carry it out of the unit via a drain line. Without this integral component, the condensation could find its way to the system’s inner workings and cause damage. The same thing can happen if it overflows. Routine inspections and maintenance can help rectify this issue.
Here Air Pro Inc., your local air conditioning replacement contractor, lists three reasons why the condensate pan of an AC unit overflows.
Condensation occurs when warm air passes over the cold coils, turning water vapor into water. This water then moves toward a small pipe and into the drip pan. The condensate pan turns on automatically as the water rises in the drip pan, preventing issues with overflowing. If it’s broken or damaged, it needs to be replaced as soon as possible to protect the interior unit from damage. A replacement condensate pump is relatively inexpensive, though installing it requires the expertise of a certified technician.
Algae, calcium and other mineral deposits can form inside the drain line due to the constant flow of condensation. Too much of this blocksage can hinder proper water flow, causing it to back up and overflow into the drip pan. Air conditioning repair pros recommend using a pipe-cleaning solution to clean the inside of the drain line.
Your AC unit can still experience an overflow at the condensate pan even when the drain line isn’t clogged. Low refrigerant levels lead to ice formation on the evaporator coils. As this ice melts, more water gets collected by the pan, preventing the line from draining condensation out of the system. Reach out to a certified technician who can inspect and fix the issue right away.
