Air Conditioning System Maintenance

SAN JOSE — When properly installed, a home air conditioning system should last for at least 20 years. However, in order for the system to reach its expected lifespan, ongoing maintenance must be observed. In addition to prolonging the system’s operating lifespan, maintenance will help prevent problems and sustain energy-efficient performance. Consider the following maintenance steps:

1. Clean out the condensate drain line on a regular basis. This small, plastic pipe conveys condensation created by the air conditioning unit to the outside of the home. Typically, a condensate drain line has an access point that’s located near the unit. Find the access point and pour half a cup of bleach down into the line. This will clean the drain line and prevent clogs or bad odors caused by mold/mildew buildup.

2. Every couple of years, have your air conditioner’s freon level checked by a professional. When freon gets low, the system’s compressor must work harder, which wastes energy.

3. Every two to three years, wash the condenser coils in your air conditioning unit. Since condenser coils work more efficiently when they’re clean, this step can help you save on your electricity bills.
