With the changing leaves and cooler temperatures in autumn, performing some routine HVAC maintenance before winter ensures your system stays efficient and functions properly. While a professional HVAC service can thoroughly inspect and repair any issues, there are several ways to prepare the system at home. Below are some strategies to help you get your furnace and air conditioner ready.

What HVAC Maintenance Issues Should You Handle During Fall?

1. Change the Air Filter

The filter in your HVAC system traps dust, dander, hair, and other airborne contaminants before they can circulate throughout the house. Over time, this debris accumulates and clogs the filter, restricting the airflow. This forces the furnace to work harder to push air through, leaving your home colder and accelerating wear and tear on the appliance. Before you turn the furnace on for the season, swap the filter. Then, check it monthly and replace it when debris clogs the screen.

2. Clean the Outdoor Unit

While the falling, colorful leaves are picturesque, this organic debris tends to accumulate around the outdoor HVAC unit. The buildup of leaves and twigs can get lodged in the openings on the unit, restricting the airflow. This makes it harder for your system to draw in air during a heating or cooling cycle. In extreme cases, dry leaves could even pose a fire hazard, as they are more flammable than healthy, moist leaves. Clean and clear the area around your outdoor unit to avoid potential repair issues from overworking the system.

3. Check Thermostat Settings

As the outside temperature drops, adjust your thermostat accordingly. If you have a programmable thermostat, set the system so that it won't run as frequently when everyone is away at work and school. Also, make sure the unit is set to transition from air conditioning to heating. If your thermostat is old and doesn't provide an accurate temperature, an HVAC service can upgrade it to a smart model that you can control from your phone, improving your family's comfort and the energy efficiency of the home.
