10 Easy HVAC Tips to Help Homeowners Save Money Year-Round

Your home’s heating and cooling system is one of the biggest contributors to your energy bill. The good news: a few simple changes can cut those costs without sacrificing comfort. Here are ten easy, mostly free HVAC tips to help you save all year long.

1. Change Your Air Filter Regularly

A dirty filter makes the system work harder, burns more energy, and invites breakdowns. Replace it every one to three months — more often with pets or allergies. It is the cheapest win on this list.

2. Install a Programmable or Smart Thermostat

A smart thermostat adjusts temperatures around your schedule so you are not heating or cooling an empty house. Used correctly, it can trim a meaningful share of your heating and cooling costs.

3. Schedule Annual HVAC Maintenance

A yearly tune-up keeps the system efficient, extends its life, and catches small problems before they become expensive repairs. Book the AC in spring and the furnace in fall — our furnace maintenance tips cover what to do between visits.

4. Seal Air Leaks

Gaps around windows, doors, and ductwork let conditioned air escape and waste energy. Caulking, weather stripping, and professional duct sealing all help keep the air you paid for inside.

5. Use Ceiling Fans to Circulate Air

Fans don’t cool the air, but they make you feel cooler, letting you raise the thermostat a few degrees in summer. In winter, reverse the fan direction to push warm air down from the ceiling.

6. Close Vents in Unused Rooms (Carefully)

If you rarely use a room, partly closing its vents and door reduces the area your system has to condition. Don’t overdo it, though — closing too many vents can throw off airflow balance in some systems.

7. Upgrade to a High-Efficiency System

If your equipment is over 15 years old, a new ENERGY STAR-rated unit uses significantly less energy and may qualify for current rebates through the Home Renovation Savings Program. Our guide on what SEER2 ratings mean helps you compare efficiency.

8. Keep Vents and Registers Clear

Make sure furniture, rugs, and curtains aren’t blocking your vents. Blocked airflow makes the system work harder. Aim for at least 12 inches of clear space around each vent.

9. Use Curtains Strategically

In summer, close curtains during peak sun to block heat. In winter, open them by day to let warmth in and close them at night to keep it. Simple, free, and surprisingly effective.

10. Don’t Crank the Thermostat

Setting the thermostat way up or down doesn’t heat or cool faster — it just runs the system longer. Pick a steady, efficient setpoint:

• Winter: 20°C (68°F) at home, 17°C (62°F) away or asleep
• Summer: 24–25°C at home

The takeaway: clean filters, a smart thermostat, sealed leaks, and steady setpoints deliver most of the savings — no major spending required.
