How to Stop Leaking From the Front of a Sears Window Air Conditioner

Whether you use your Sears air conditioner only during the hottest part of the summer or for the entire season, it is a good idea to have some basic troubleshooting skills. While Sears air conditioners are designed to be largely maintenance-free, there are a few things you need to be aware of when running your unit. Making sure the air conditioner is properly installed and knowing where to look for leaks is the best way to keep your unit operating smoothly.

Instructions

- 1
  Check for air leakage around the sides, top and bottom of the Sears air conditioner. Look for any visible holes and cracks in the sides of the air conditioner and patch any you find. Test for more subtle air leakage by running the air conditioner for 30 minutes, then shining a flashlight along the bottom. If you see water droplets forming there, you need to install additional foam insulation around the unit to prevent air from leaking and condensing at the front.

  Examine the drain hole at the back of the air conditioner. If the drain hole is blocked, use a small stick or piece of wood to dislodge any debris.
- 3
  Pull the drain pan out of the air conditioner and empty it. Check the drain pan on a regular basis. If water accumulates inside the drain pan and is not regularly emptied, it can condense and drip out the front and onto the floor.
