Air Conditioner is dripping water

If the air conditioner is dripping and after reading this article a problem still found, contact a service professional.

Possible Causes: Water condensating from the evaporator coil is draining into the home instead of out the rear of the unit through the drain tube. The pan is not sloping down toward the exterior, but rather into the home.

Possible Solutions: Correct the slop of the unit so that it drains to the exterior and slopes slightly downward toward the exterior.

Room size can be a factor in over loading an air conditioner - causing frost or ice build up and melting.

There are times when the hot weather is so brutal that an air conditioner is on 24 hours a day, 7 days a week. That's perfectly fine, unless the air conditioner is leaking into the home and causing water damage. Here are a few ways to stop an air conditioner from dripping water inside of the room.

• Ensure the air conditioner is installed properly. Window units should have the front slightly higher than the rear of the air conditioner. A 1 to ¼-inch difference between the front and the rear is sufficient for proper draining. This allows the water to roll out the back of the unit. If the front is lower than the back, then water can drip into the home.		• Prevent a warm airflow from settling around the front of the air conditioner. If an air conditioner is in a position where there is a flow of warm air, condensation occurs. The condensation can cause a buildup of water that may drip inside a room.

		• Check for icing. If the cooling coil is icing up, the melting ice may drain into a house. Remove the front cover and check your air conditioner's cooling coil (evaporator). If ice is found forming, check the room size and BTU rating of the air conditioner or contact a service professional.

• Unblock the air conditioner's drain hole. The back of an air conditioner has a hole or groove that allows water to escape and drain off. If it clogs, the water cannot flow and may back up dripping inside the home.
