As outdoor temperatures gradually cool down, you’ll likely rely less on your air conditioner. Even without running it as frequently, you should prepare the heating and cooling system for fall so that it continues to function efficiently when you need it. Here are some ways to prepare your air conditioner for the autumn months.

4 Tips to Get an Air Conditioner Ready for Fall

1. Remove Obstructions

Condenser units pull in warm air from the outside before cooling it and circulating it throughout your space. However, fallen branches and leafy debris may block the outdoor unit, forcing it to work harder to pull in air through the blockage. This also provides a hospitable environment for mold growth, which can contaminate the air in your system. Remove these obstructions to keep your indoor areas comfortable and prevent elevated utility bills.

2. Change the Filter

Filters remove dirt, dust, pollen, and pet dander from the air before it can circulate throughout the home. Even when you don’t run your heating and cooling unit, the filter will continue to collect debris from passive airflow. Change the filter at least once a month to minimize allergy flareups and improve the quality of your indoor air.

3. Calibrate the Thermostat

Since outdoor temperatures fluctuate in the fall, you might change the settings on your thermostat more frequently. However, this throws off the calibration, preventing your heating and cooling system from reaching an accurate temperature. Maintain precise readings by removing the thermostat cover and cleaning off any debris and corrosion that you see. Also, if you have an older, mechanical thermostat, have an HVAC contractor adjust the calibration screw, heat anticipator, and mercury levels.

4. Clean the Ducts 

When vents collect dirt and dust, the air from your heating and cooling system picks up this debris and spreads it throughout the home. To prevent this, vacuum the vents with a handheld attachment or long-handled brush. This will remove debris from the cover and help to prevent allergy flareups. Additionally, unscrew the vents and clean out the interior.
