10 In-Home Tips to Maximize Your HVAC System’s Efficiency

Keep Your HVAC System Running at Peak Performance Year-Round

Your HVAC system works hard to keep your home comfortable—whether it’s cooling you off in the summer or keeping you warm in the winter. But if it’s not running efficiently, it could be costing you money and wearing out faster than it should.

The good news? You can take simple steps right at home to get the most out of your system. Here are 10 in-home HVAC efficiency tips to reduce your energy bills, improve indoor air quality, and prolong the life of your heating and cooling equipment.

1. Change Your Air Filters Regularly

A clogged air filter restricts airflow, forcing your system to work harder and use more energy.
Tip: Replace filters every 1–3 months, depending on your system and household needs (especially if you have pets or allergies).

2. Keep Vents & Registers Clean and Unblocked

Blocked or dirty vents reduce airflow and efficiency.
Tip: Make sure furniture, curtains, and rugs aren’t covering your vents, and dust them regularly to prevent buildup.

3. Use a Programmable or Smart Thermostat

A smart thermostat automatically adjusts the temperature based on your schedule, cutting down on energy use when you're away.
Tip: Set it to raise or lower temps during work hours or overnight to save on heating and cooling costs.

4. Seal Air Leaks Around Windows and Doors

Drafty windows and doors let conditioned air escape and outside air in, making your system work overtime.
Tip: Use weather stripping or caulking to seal leaks and improve insulation.

5. Keep Heat-Producing Appliances Away from the Thermostat

Lamps, TVs, and other electronics can make your thermostat think the room is warmer than it is.
Tip: Place these items away from the thermostat to get more accurate temperature readings.

6. Use Ceiling Fans to Support Airflow

Ceiling fans help distribute heated or cooled air more evenly throughout your home.
Tip: Set fans to spin counterclockwise in summer and clockwise in winter.

7. Close Curtains During Summer & Open Them in Winter

Sunlight can drastically change your indoor temperature.
Tip: In hot months, keep curtains closed during the day. In cold months, open them to let in natural heat.

8. Schedule Annual HVAC Maintenance

Even if your system seems fine, small issues can go unnoticed and lead to costly repairs.
Tip: Schedule a professional HVAC tune-up at least once a year—ideally in spring and fall.

9. Check and Seal Ductwork

Leaky ducts can waste up to 30% of your system’s air output!
Tip: Have your ductwork inspected and sealed to ensure maximum efficiency.

10. Upgrade to Energy-Efficient HVAC Equipment

If your system is more than 10–15 years old, it may be costing you more than you realize.
Tip: Consider upgrading to an ENERGY STAR® certified system to lower energy use and increase home comfort.

Final Thoughts: Small Changes, Big Savings

Maximizing your HVAC efficiency doesn’t have to be complicated. With just a few small changes around your home, you can make a big difference in your comfort, system lifespan, and energy bills.
