An overflowing condensate pan can be caused by several factors. If left unaddressed, this can turn into a serious hazard where the excess water will saturate your home’s ceiling and lead to rot and mold. You should also know that this type of issue often goes unnoticed unless your system is regularly inspected. As a homeowner, inspecting your attic regularly isn’t difficult to do as you can look for leaks in the AC drip pan as well as other signs of moisture buildup. And to help you out, our residential and commercial AC maintenance specialists at Air Products & Services share some of the biggest causes of an overflowing condensate pan.
Even if the drain line of your unit gets rid of excessive condensate, the water will still flow at a certain rate. If the condensation buildup exceeds the drain line’s ability to remove the water, it will overflow. This also happens when low refrigerant levels create ice on the evaporator coil. When it melts, it creates additional water that may be too much for the drain system to handle.
Water from the condensate pan that constantly flows down through the drain line can lead to buildups of algae, calcium and other deposits. These eventually restrict the water from flowing normally and cause it to back up and overflow in the pan. If you think that this is what’s causing your condensate pan to overflow, try flushing it out with a pipe cleaning solution or contact an experienced residential AC technician for assistance.
A functional HVAC system has its condensate pump on automatically whenever the water in its drip pan reaches a certain point. But if it overflows, that means that the condensate pump probably didn’t turn on as it should. While small amounts of water in your AC’s condensate pan are perfectly normal, if you notice that it’s overflowing, it may be due to a faulty pump.
