Regular HVAC maintenance, like cleaning filters and checking thermostats, can improve efficiency, lower gas bills, and prevent costly repairs during colder months.
At a Glance:
- Regular HVAC maintenance prevents inefficiencies that can lead to higher energy bills and costly repairs.
- Small issues like dirty filters and clogged drains can increase energy use, making your system work harder and less efficiently.
- Upgrading your HVAC, your thermostat and checking for refrigerant leaks can lead to significant energy savings over time.
As fall approaches and temperatures start to drop, many homeowners see their energy bills increase. While rising energy costs play a role, often the root cause is hidden in your HVAC system’s inefficiencies. To avoid unnecessary costs and ensure your system runs smoothly, performing regular maintenance checks is key.
Here are 10 essential maintenance tasks for HVAC systems—whether you have a furnace, boiler, air conditioner, or heat pump—that should be done before fall.
1. Replace or Clean Air Filters
Why: Dirty filters restrict airflow, forcing your system to work harder and reducing its efficiency.
How: Replace disposable filters or clean reusable ones at least every 1-3 months, especially before heavy heating season use. This simple task can significantly improve performance and lower energy costs.
2. Check Thermostat Settings
Why: A properly functioning thermostat ensures your system isn’t running unnecessarily, keeping your home comfortable without wasting energy.
How: Test both cooling and heating modes to confirm your thermostat responds correctly. Consider upgrading to a programmable or smart thermostat for more efficient control.
3. Inspect the Heat Exchanger (Furnaces and Boilers)
Why: A cracked heat exchanger can lead to carbon monoxide leaks, which are hazardous to your household.
How: Have a professional inspect the heat exchanger for signs of wear, corrosion, or cracks. This is a critical safety check for anyone using a gas furnace or boiler.
4. Clean and Inspect Ductwork
Why: Blockages or leaks in your ducts can prevent air from circulating properly, reducing the efficiency of your HVAC system.
How: Check for dust buildup and visible leaks in your ductwork. If you notice issues, hire a professional to perform a more thorough inspection and cleaning.
5. Check and Clear Outdoor Units (ACs and Heat Pumps)
Why: Dirt, leaves, and other debris can block airflow, making your system work harder and reducing its efficiency.
How: Turn off the power to the unit and remove any debris around it. Ensure there’s at least 2 feet of clearance around your outdoor unit to promote proper airflow.

6. Inspect the Condensate Drain
Why: A clogged condensate drain can cause water damage and increase indoor humidity, which can make your heating system less efficient.
How: Check for any blockages in the drain and ensure it’s draining properly. Use a wet vac if necessary to clear clogs.
7. Check Refrigerant Levels (ACs and Heat Pumps)
Why: Low refrigerant levels can cause your system to cool inefficiently, even in the fall when temperatures fluctuate.
How: Have a professional check the refrigerant levels and address any leaks immediately. This helps maintain system performance and prevent costly breakdowns.
8. Test Ignition Systems and Pilot Lights (Furnaces and Boilers)
Why: A faulty ignition system or pilot light can prevent your heating system from turning on when needed.
How: Test your system’s ignition or pilot light and ensure it starts up without issues. If you notice delays or failures, call a professional for further inspection.
9. Inspect Belts and Pulleys (Furnaces and AC Units)
Why: Worn belts or pulleys can make your system less efficient or cause it to break down.
How: Look for signs of wear, such as cracks, fraying, or slack. Listen for squealing noises, which indicate belt issues, and replace them as needed.
10. Clean or Replace Burner Jets (Furnaces and Boilers)
Why: Dirty burner jets reduce heating efficiency, causing uneven heating throughout your home.
How: Inspect the burner jets for soot or debris. Clean them carefully, or have a professional do it to ensure your system runs smoothly.
Conclusion:
Taking the time to complete these maintenance tasks before the colder months set in can help lower your gas bill, improve energy efficiency, and prevent breakdowns during peak usage. By keeping your HVAC system in top shape, you’ll avoid costly repairs and ensure a comfortable home all fall and winter long.
