In humid South Texas your A/C will produce a lot of water from the dehumidification process. However, pooling or leaking may indicate a more serious problem. There are several possible causes of pooling, and most of them must be fixed for your unit to run efficiently.
Why Your A/C is Leaking Water
Broken Condenser Pump: If your system has a condensate pump test to see if it is working by pouring water into the condensate pan. If it’s functioning, it will pump excess water out. If it fails to remove the water, find out if the pump has power. If it does, the problem may lie with the motor or the condenser. Get an HVAC professional to examine your system.
Bad Installation: Poor installation can cause air conditioning units to leak water. For example, if it’s not level or if the pressure is too much, pooling may result. First, find out if your unit is level, then look for closed vents in your house if levelness is not the issue. In some cases, added pressure can cause valves to leak.
Blocked Drain: If a drain is blocked, water has nowhere to go, but back into your home. So, make sure to check if algae or debris has blocked your drain. Once you clear it, the pooling should stop.
Low Outside Temperature: Cooler temperatures outdoors can cause your A/C to leak. Cooler temperatures result in extra water that doesn’t evaporate normally. If there’s not much water, then you might be able to ignore it. Once temperatures rise again, there will be no extra water.
Leaking Air: If A/C seals are not sufficiently tight, warm air can enter your unit, and the moisture will condense when it combines with the cold air inside your A/C.
