Fall HVAC Maintenance Checklist

Fall is officially here, which makes it the perfect time to get your HVAC system ready for the colder months. Proper HVAC maintenance is key to extending the life of your system and ensuring it performs at its best. Below is our go-to fall HVAC maintenance checklist to help you get the most out of your heating system this season.

1. Replace the Air Filter Regularly

Air filters should be changed every 1-3 months to avoid them getting clogged, restricting airflow and forcing your furnace to work harder. If you want to take it a step further, opting for a high-efficiency filter can improve indoor air quality by trapping even microscopic pollutants.

2. Optimize Your Thermostat Settings

For energy savings, set your thermostat to 70 degrees or below at home and around 62 degrees when away or sleeping. If that’s too chilly, adjust to your comfort, changing one degree at a time to stay efficient. A smart thermostat can automate these adjustments for extra control and savings.

3. Clean and Inspect Air Vents

Check all air duct registers throughout your home. Use a vacuum with a brush attachment to remove dust from vents and ensure no furniture, rugs, or curtains are blocking airflow. Closing vents in unused rooms may seem like a cost-saving move, but it can disrupt airflow and increase energy costs. Keep at least 80 percent of your registers open for proper circulation.

4. Seal Leaks in the Ductwork

Leaky air ducts can waste energy and drive up your heating bills. Duct tape isn’t a permanent fix, so it’s best to have an HVAC professional seal them properly. Doing so can make your home more comfortable, lower your energy costs, and even improve indoor air quality.

5. Prevent Heating-Related Fires

Keep flammable items at least three feet away from heaters, fireplaces, furnaces, and other gas appliances. Never leave a running space heater unattended or plug it into an extension cord. If you notice unusual noises or smells, turn off your system and contact an HVAC professional immediately.

6. Keep the Utility Room Clear

Furnaces need space to operate safely. Keep at least 10 to 15 feet clear around your unit. In small utility closets, store only your HVAC equipment and keep flammable items like paint and cleaning supplies separate.

7. Test Smoke Alarms and Carbon Monoxide Detectors

Test these safety devices monthly to ensure they work correctly and replace the batteries annually. Only remove batteries if you are replacing them immediately.

8. Schedule Professional HVAC Maintenance

Some maintenance tasks can be done yourself, but a professional provides a thorough inspection, cleaning, and tune-up. Preventive HVAC maintenance keeps your system running efficiently and reduces the risk of emergency repairs.

9. Consider Replacing Your HVAC System

Furnaces over 15-20 years old may operate at only 60 percent efficiency. Instead of waiting for a complete failure, consider replacing your system. A new high-efficiency furnace can convert up to 97 percent of fuel to heat, providing immediate energy savings and long-term comfort.
