Do you need to do some air conditioning troubleshooting? If you have a puddle under the AC unit, the answer is yes. Keep reading to consider some of the possible issues to help you determine if it’s something that requires professional service.
What Level of Condensation Is Normal?
A small amount of condensation is normal for any air conditioning unit. As it works to cool your home, it pulls in hot air and passes it over the evaporator coil to cool it. The humidity is pulled from the air and it creates condensation, just like the condensation on a glass of ice water on a hot summer day. The trick is that the condensation should drop into a drain pan and down a drain line. It should not leave a puddle under the unit itself.
What Could Be the Problem?
If you find a pool of water under your AC unit, take a look at some of the more common causes:
- A clogged drain pan or drain line will cause water to back up and overflow the pan and collect under the AC equipment. If you clean the drain and clear the way for the water, it could stop the leaking.
- A frozen evaporator coil will eventually melt and the water will end up under the unit instead of in the drain pan. The cause could be a dirty air filter or low refrigerant. You can check and change the filter yourself to possibly fix the problem, but low refrigerant requires professional service.
- A condensation trap or drain that is improperly installed can cause leaks leading to pooling water. This problem would require maintenance by an HVAC technician.
- Improper insulation can cause condensation to build up on the pipes and leak down. This is another issue that would require a professional to fix.
Although condensation is a normal part of a properly functioning air conditioner, water that is leaking and pooling under the unit is not. For help with troubleshooting as well as professional repair, if needed, contact the pros at Universal Heating and Cooling.
