Why an Air Conditioner May Leak Water
The condensation pump removes condensation from the unit, so leakages can happen if it's not working correctly.
One of the functions of an air conditioner's function is to remove excess moisture from indoor air. The resulting condensation drains away without incident under normal operation, so a puddle around the unit indicates a mechanical issue. Consider the five possible reasons why an air conditioner leaks water to identify the source of the issue.
Blocked condensate drain
Dirt, algae, and other debris can block the condensate drain where excess moisture inside the home is supposed to drain. If this happens, water can pour over the sides of the drain pan and pool around the unit. Stick a straightened coat hanger into the condensate drain to clear the blockage. If it continues to be a problem, hire a professional to apply an algaecide treatment that stops future microbial growth.
Incorrect installation
Never attempt to install an AC unit without professional help. A poor job could cause the unit to leak water if it's not properly leveled or is overcharged during installation. Hire a professional to level out the unit or fix its charge to reduce pressure on the system's valves and stop the leaking.
Broken condenser pump
The condensation pump removes condensation from the unit, so leakages can happen if it's not working correctly. First, ensure the condenser pump receives power to determine if this is the problem. Test the pump by pouring water into the condenser pan; if the water lingers without being pumped away, then the pump is the culprit and must be replaced by a professional.
Air leak
Under regular operation, air conditioners are sealed to prevent warm air from entering the system. When this happens, water vapor in the warm air condenses as it comes in contact with cool air cycling through the unit. This extra moisture could cause a leak, which a professional can fix.
Cold outside temperatures
If the A/C runs while outdoor temperatures drop, excess water can build up around the unit because it's not hot enough to evaporate. Stop the problem and save money by opening windows instead of running the air conditioner as it cools off outside.
Like any machine, air conditioning units are susceptible to mechanical issues. If water starts to pool around the machine's base, consider these causes to try and resolve the issue. Always contact a professional when in doubt, as expert care is the quickest and most effective way to repair an air conditioner to working order and keep the house cool.
