Schedule a Professional Tune-Up

Fall is the ideal time for a professional HVAC tune-up. A certified technician will inspect all components, check for wear and tear, test safety controls, and ensure your system is running at peak performance. If you haven’t already, make sure to schedule your yearly furnace inspection to prevent unexpected breakdowns when you need heat the most.

Check Your Thermostat Settings

Reprogram your thermostat for cooler weather. Lowering your home’s temperature when you're away or asleep can lead to significant energy savings. If you don’t have a programmable or smart thermostat, fall is a great time to consider installing one.

Seal Drafts and Inspect Insulation

Prevent heat loss by sealing gaps around doors, windows, and ductwork. Also check attic and wall insulation levels. Proper sealing helps your HVAC system maintain desired temperatures more efficiently.

Clean Around Outdoor Units

Remove leaves, dirt, and debris from around your outdoor AC or heat pump units. At least two feet of clearance around the unit is recommended for proper airflow. This step also helps extend the lifespan of your system.

Inspect Ductwork for Leaks

Leaky ducts can waste a significant amount of heated air. Consider scheduling a duct inspection and sealing service if you notice uneven heating or higher-than-normal utility bills.

Don’t Forget About Your Dryer Vents

While you're doing fall maintenance, don’t forget about your dryer vents. Clogged vents can reduce appliance efficiency and pose fire hazards and fall is a great time to clear them out.
