Water dripping from air conditioners may be a common sight whenever you pass by a row of houses in your neighborhood, but have you ever considered that it could be bad news? If you find the same thing happening to your air conditioner at home, you should be aware that you could be facing a problem — one that could cost you a significant amount of money as well as a considerable amount of hassle if left unchecked.
Leaky air conditioning units are the subject of almost 90 percent of all calls made to HVAC specialists. You have to know the signs of a leaking air conditioner so that you can get immediate help before the issue becomes more serious.
Does my AC have a leak?
Air conditioners can leak for a number of reasons, but there are a few major causes that you can specifically look out for to help identify the problem:
You know you should be regularly changing your unit’s air filters, but there will be times when this task will quite easily slip your mind because of other responsibilities. Check if the filter has become dirty, and if it does, be sure to change it promptly. Ice will form on the evaporator coils of your unit when there is a dirty filter, and naturally, this ice will melt and cause water to drip.
Damaged overflow drain pans
This is one of the most likely causes of leaks; the pan is designed to catch all condensation from your air conditioner, so if water is getting out of this pan, there may be a hole or a crack in it. Follow the spots where water is dripping, and inspect the sides of the pan directly above or around these spots. You can use epoxy glue to patch up minor cracks and holes, but if there is greater damage, it’s best to replace the old pan with a new one.
A blocked condensate line
This air conditioner component takes the collected condensation from the overflow drain pan to the house’s exterior or into a drainpipe. If this line becomes stopped up, the pan will be flooded and leak.
Improper unit installation
Some HVAC technicians may incorrectly install a unit, such that the unit is slightly lower in the rear than it is in front. The water that an air conditioner takes from a room will then drain toward the back of the unit. On the other hand, if the unit is installed so that it is lower in front, the water will flow into the room instead of outside.
Air leaking around the air conditioner.
It’s also possible that your unit is leaking because warm air from outside is finding its way into the house, through spaces around the air conditioner itself. This causes warm air to meet cool air, which creates condensation.
Sometimes the issue is not the instillation itself, but a faulty part on the origional air conditioner unit. One of the more common parts that may fail under warranty is a coil. An HVAC technician can help you determine if this is the case.
Some of these causes of air conditioner leaks can be resolved using simple methods, but if the problem persists or if the leaks are affecting the way your unit is functioning, it’s best to call in your trusted local HVAC specialists to take a look at the unit and get it back into shape.
