End-of-Season HVAC Checks for Whittier Residents

With the summer heat winding down, it’s a great time to take a closer look at your HVAC system. You want to be sure your heating system is prepared for the winter ahead and your AC is ready for next summer. An HVAC filter change in Whittier, CA, and these preventive maintenance tips can help protect your HVAC system.


Change Your HVAC Air Filter

The first thing you should do at the end of the season is check your air filter. Central air systems often have one filter for both the AC and heating. That means a blocked filter will impact performance for both. Most filters should be checked every three months and replaced as needed.


Clean Around Your Outdoor AC Unit

Watch out for leaves building up around your outdoor AC unit. Not only can they work their way inside and damage internal components, but they also hold moisture that can cause corrosion. Trim any plants that are getting too close to the outdoor unit, and take care of any other clutter in the area.


Book a Professional HVAC Tune-Up

A professional tune-up is a great option during the fall. You can ensure your heating system is prepared for the season ahead and avoid potential breakdowns. Technicians can identify any problems before they get worse, ensuring your system continues to run smoothly for years to come.


Make Sure Your Thermostat Is Working

The end of the season is a good time to check your thermostat, as it has a huge impact on cooling and heating performance. Make sure your system is capable of reaching the specified temperature and that it does so accurately. Double-check using a separate thermometer, and look at the temperature in more than one spot to ensure consistency.
