Why is my air conditioner leaking? - Mykawartha.com
If your air conditioner is leaking, it's a sign that there is a problem with it. Finding the source of the leak can be challenging, especially if the leak is sporadic or if it seems to be leaking from different places.
An air conditioner doesn't just blow cool air into your home it also removes the humidity from your home. As the humid air passes through the air conditioner, condensation occurs and water forms on the evaporator coil. This water then travels to a drain pan, then down a drain line into your plumbing or outside of your house. If the flow of water is interrupted or stopped, this will cause your air conditioner to leak.
The drain line can become clogged with dirt, bugs, lint, pet hair, etc. If you can see the clog, you can try to remove it. If it's too far down the line, it's best to call the experts at Eakins Heating & Cooling to remove it.
Another source of the leak could be the drain pan. If it's rusted or damaged, water can escape before it heads down the drain line. The drain pan will need to be replaced by a professional to stop the leak.
Another potential cause of a leak is if your air conditioner is "icing up." This happens when the evaporator coil freezes, then melts, the influx of water may overflow out of the drain pan. The evaporator coil can freeze if the air filter is dirty or if your air conditioner is low on refrigerant.
If your air conditioner was installed recently, improper installation could be the cause. If the condensation trap was not installed properly, leaks can occur.
