The AC Is Leaking Water Inside Your House – What To Do Now?
Rainier Heating & Cooling, LLC • October 20, 2025

If your AC is leaking water inside your house, you should turn it off and clean up the water that has dripped. Water can start to damage your home quickly during leakages, so you will want to protect your house from any potential harm while figuring out what’s causing it.

Water damage is a costly affair to fix, and once your AC starts leaking, it would not take long to destroy your furniture, carpet, and walls.

Here are some of the most common reasons why your AC is leaking inside your house:

Dirty air filter

All air conditioners contain an air filter. This air filter removes fine dirt particles from the outdoors, allowing only clean air to enter your home. As a result, the AC filters must be cleaned regularly. If the air filter gets blocked up, the air conditioner’s evaporator coils will freeze, causing the excess water droplets to spill inside your home.

Broken condensate tray

The water condensed from evaporator coils is collected in the condensate tray of your air conditioner. By any chance, if the tray is fractured, rusty, or damaged, water will leak out of it when the air conditioner is turned on. In this case, you need to contact an air conditioner repair Puyallup and get the tray replaced as soon as possible.

Blocked drain pipe

Water backs up into your home if the drain line becomes clogged with mold, dirt, or fungus. You will have to unclog it in that situation. Unclogging the drain line can be done in many ways. For example, you could use a dry or wet vacuum on the condensate line. However, it is always best to use professional help and get it cleaned safely.

Faulty installation

If your air conditioner is new or has recently been serviced, you should check to see if the installation was done correctly. Incorrect or poor AC installations frequently cause water leakage. The condensed water will start trickling into the room if there is a gap between the unit and the condensate tray. So be cautious when installing the air conditioner and ensure that heating and air conditioning reviews in Puyallup are good enough before you contact them for service.

Low refrigerant levels

The refrigerant in the air conditioner must be at appropriate levels. The AC pressure may drop if the refrigerant levels are low. As a result, the evaporator coils will freeze, and water will seep in. So make sure that you add the proper amount of refrigerant to the air conditioner as recommended by your manufacturer.
