As the summer ends, it’s a great time to take stock of your air conditioner’s performance. If you have been using your A/C all season, a routine check-up is in order before retiring it for the colder months. Here are some end of summer air conditioning maintenance tips to ensure your cooling system is in optimal shape for next summer:

Inspect and replace the air filter

Checking your filters to see if they need cleaning or replacing can help improve air quality significantly and provide proper airflow. You may also want to use this time to upgrade from a fiberglass filter to a pleated or an electrostatic filter. Pleated air filters offer almost the same filtration performance as a true HEPA filter. In contrast, electrostatic filters use static electricity to attract and trap more dust and allergens.

Check electrical connections

It’s essential to check the unit’s electrical system to avoid a potentially hazardous situation. Look for any dislodged, stripped, or pinched wires. If you find any damage, you may need a technician to replace the wiring or insulation.

Observe your unit

The first thing you will want to do is check for unusual sounds, appearances, or smells, such as rattling or hissing sounds, visible moisture on the unit or around the tubing, and odd odors of possible mildew or mold. Those are all signs that your A/C needs servicing.

Clean the condenser and evaporator coils

Cleaning and unclogging all coils of dirt and debris can extend the life and efficiency of your unit and decrease energy costs. Plus, you will prevent the spread of mildew throughout your system. You may also need to clean the area around the air conditioner if it’s near any tall grass, weeds, or broken branches, which can block the airflow.
