Window air conditioning systems are typically reliable and effective tools for helping you beat the summer heat. Unfortunately, they are also prone to some malfunctions. If you are struggling with moisture problems and water leaking from your window-mount air conditioner, here are a few tips to narrow down the source of the problem and help dry things out.
Check the Installation
In order for a window air conditioner to function as intended, the installation must be precise. Check the balance of the air conditioner to make sure that it is slightly pitched toward the exterior of the house. This angle will encourage proper drainage of any condensation that may accumulate from the inner coils of the air conditioner.
If the air conditioner is installed on an improper angle, the water dripping from the coils is likely to run back into your home's interior. In order to determine if this is the problem, watch to see where the water is coming from. If it's dripping from the front of the unit, that means that the water channels are backed up and draining in the wrong direction. Tilt the unit upward a bit to drain the water outside.
Inspect the Filter
The air filter installed on the front panel of the air conditioner keeps particles and contaminants out of the air conditioner and away from the coils. If the air filter gets clogged, it can inhibit the air flow, which may cause the system to condensate inside. Make sure that you keep the filter cleaned or replaced regularly to make sure that the air flow is sufficient through the system.
Test for Air Gaps
Another common problem for window air conditioners is air leaks. If warm air from outside is seeping in around the cool air from inside, you're going to have condensation form on the outside of the air conditioner. This can lead to drips inside the house. Cover the area around the air conditioner with some foam insulation material to prevent the air transfer indoors.
Clean the Coils
Any time you run a window air conditioner with a dirty air filter for a long time, the coils run the risk of contamination. You'll have to check out the site and keep the coils clean in order to keep the air conditioner functioning properly. In order for the air conditioner to function as intended, you need to keep the coils as clean as possible, otherwise the condensation will build up and drain inside the house.
Unplug the air conditioner and pull the front grille off. Remove the filter to access the coils. Wipe the coils down with a lint-free rag soaked with warm water and a mild detergent. The detergent will help to clean the coils and so that the system will function properly.
Clear the Condensation Drain
The condensation drain pan collects all of the moisture that falls from the coils as the system runs. The accumulated water will drain from the pan to the drain lines. If the drain pan and lines get clogged from debris, you'll need to clean it out to prevent water from draining inside the house. Take the pan out of the air conditioner, then clean it with a damp cloth. Rinse it with a vinegar and warm water solution to remove any bacteria. Dry it thoroughly, then replace it.
Air conditioning systems require a delicate balance to function as intended. With the tips presented here, you can spot the cause of water leaks in your home as well as inefficiencies in the operation of the air conditioner itself. Keep the system clean and maintained to keep things cool and protect your home from leaks.
