Wait—Is My AC Leaking Water?

Have you made the surprising discovery of a pool of Leaking Waterwater surrounding your indoor AC unit? If so, you may be a bit confused. After all, the AC cannot be leaking water because it does not use water in its operation. Right? Well … sort of. No, that water is not the result of a “leak” in the terms that you are likely thinking of. However, this actually does not mean that your air conditioner is not the source of the water.

This water not only may be coming from your air conditioning system, but could also suggest that you are dealing with a very serious problem. Or it could be something very benign that you can resolve on your own. Like most air conditioning issues, there are various reasons why you may encounter this particular symptom. Getting to the source of the issue is the best way to protect your property and your air conditioner in Wellington, CO.

Dirty Filter

What could a dirty air filter possibly have to do with the water surrounding your air conditioning system? Well, a very dirty air filter could significantly restrict airflow through your home cooling system. When that happens, the evaporator coil will struggle to draw a sufficient amount of heat out of the air. This will cause the coil to get much colder than it should, which could cause the condensation on the coil to freeze up. When that happens, the ice melting off could overwhelm the drainage system and leave water all over the floor.

Refrigerant Leak

This is a much more serious issue than a dirty air filter, but can result in the same icing of the evaporator coil. The condensation that is removed from the air during the cooling process collects on the evaporator coil. If there is not enough refrigerant in your system due to leaks, that coil won’t effectively remove heat from the air. The remaining refrigerant stays too cold, ice develops, ice eventually melts, and you wind up with a puddle around your system. Your AC does not consume refrigerant, remember, so low levels suggest a leak. Continuing to run your system in this condition could prove fatal to your AC.

Drainage Issues

Your air conditioner’s primary function is, obviously, to cool your home. However, it does have a dehumidifying effect on the air that it cools. The moisture removed from the air condenses on the evaporator coil, drips off, and is drained out of your home via the condensate drain line and drain pan.

If the pan is corroded, or even if it is just misaligned, this water may leak out into your property. The drain line could also be backed up—an issue that you can resolve with a wet vac, some rags, and a homemade vinegar solution. If you have any questions about your condensate drain assembly, or if you think you need to replace the pan or the hose, just give us a call.
