Hi, this is Wayne with Sears Parts Direct. Is your central air conditioner not keeping things as cool as it should be? Here’s something to check before you make that call for service. Many central air conditioners have a drain float switch that shuts the system down if the drain is clogged and water backs up under the evaporator. If this switch trips, the air conditioner will shut down to avoid water damage. If this well under the switch is full, then it's time to unclog the drain line. You may be able to remove the clog with a shop vac. If not, you can use a plumber's snake to clear the drain line. To keep this thing from clogging up in the future, pour a cup of liquid bleach down the drain vent tube every month. The bleach kills mold and mildew that can build up inside the drain pipe and hose. To keep from killing the grass in your yard, stick a pan under the drain hose outside to catch the bleach as it runs out. And always remember to protect your eyes and skin when handling bleach and other harsh chemicals. You can get in the habit of doing this at the same time you change your air filter.
