10 Ways to Lower Your HVAC Energy Bills

HVAC: Your Biggest Energy Expense

Heating and cooling accounts for 40-50% of the average home's energy bill. Small improvements can add up to hundreds of dollars in annual savings.

1. Change Your Air Filter Regularly

A dirty filter makes your system work harder and use more energy. This simple task can reduce energy use by 5-15%.

Action: Check monthly, replace every 1-3 months.

2. Use a Programmable or Smart Thermostat

Set temperatures higher when you're away or sleeping to save money automatically.

Savings: 10-15% on heating and cooling bills.

3. Seal Air Leaks

Gaps around windows, doors, and ductwork let conditioned air escape.

Action: Use weatherstripping, caulk, and duct sealant.

4. Keep Your Outdoor Unit Clear

Debris, plants, or fencing too close to your AC restricts airflow and reduces efficiency.

Action: Maintain 2 feet of clearance around outdoor unit.

5. Use Ceiling Fans

Fans don't cool air, but they make you feel cooler, allowing you to raise the thermostat setting.

Savings: Each degree higher saves about 3% on cooling costs.

6. Close Blinds During Hot Days

Direct sunlight through windows can raise indoor temps significantly.

Action: Close blinds on south and west-facing windows during afternoon.

7. Don't Heat or Cool Empty Rooms

Close vents in unused rooms (but don't close more than 20% to avoid system strain).

Better option: Zone control or mini-splits for targeted comfort.

8. Schedule Annual Maintenance

A well-maintained system runs 15-20% more efficiently than a neglected one.

Action: Schedule tune-ups in spring (AC) and fall (furnace).

9. Check Your Ductwork

Leaky ducts can waste 20-30% of your conditioned air.

Action: Have ducts inspected and sealed professionally.

10. Upgrade Old Equipment

Systems over 10-15 years old are significantly less efficient than modern equipment.

Savings: New high-efficiency systems can reduce energy use by 20-40%.
