Top 5 furnace tune-up tips

Keep your home heating system in tip-top shape with these helpful hints

With leaves falling and temperatures dropping, it’s time to rev up your home heating. Since your Heating, Ventilation and Air Conditioning (HVAC) system accounts for almost two-thirds of your home’s energy consumption, you’ll want to make the most of your home heating budget. Keep your HVAC system in tip-top shape with these five tips from our energy experts.

1. Seal the leaks


Don’t let your HVAC system work overtime to compensate for poor insulation or drafty windows. If your home’s thermal envelope — the exterior barrier that keeps you warm in winter and cool in summer — is compromised, seal in the heat with insulation, caulking and draft-proofing.

2. Clean the vents

For maximum efficiency, clean your heating and cooling system every three to five years. Turn off the power on your HVAC. Unscrew the air duct covers from walls, floors and ceilings, and clean the grates with a brush. Use the accessories hose on your vacuum to give your ducts a thorough cleaning.

3. Replace the filters

Clogged furnace filters diminish your home’s air quality. Plus, they consume more energy and force the system to work harder. Check the furnace filters monthly, and remember to clean or replace them every 90 days, depending on whether they’re disposable or permanent.

4. Listen for noises

Clanging, knocking or popping sounds may be signs of worn-out or loose parts in your heating system. If you hear any unusual noises from your furnace, it may be time for repairs. Call a certified HVAC technician to inspect your system.

5. Have it checked

Once a year, invest in a tune-up with a qualified HVAC technician to ensure your system is running at optimal efficiency. Preventative maintenance will help spot potential issues before they become bigger problems.

To find a qualified licensed technician, call the Heating Refrigeration and Air Conditioning Institute of Canada (HRAI) at 1-877-467-4724 or check out the contractor locator portal.

The Romans invented the first central heating system, called a “hypocaust.” This system used hot air, warmed underfloor by a fire or furnace, to heat the room above.


10 tips to tune up

FaLl MainTenance checklist
  • 1

  • Book a check-up
  • Schedule servicing every fall to keep your heating system running safely and efficiently.

  • 2

  • Inspect your detectors
  • All systems that burn fuel give off gases, so put a fresh battery in your carbon monoxide detector.

  • 3

  • Clear the clutter
  • Keep the area around your furnace clear and keep flammable items well away.

  • 4

  • Change or clean furnace filters
  • Do this to improve air quality and airflow. Refer to your owner’s manual to see how often you should do this.

  • 5

  • Wrap your tank
  • Add an electric water heater blanket to insulate and reduce energy loss by up to 40 per cent.

  • 6

  • Set to save
  • Set your thermostat to 21°C when you are at home. Lower it when you are sleeping (18°C) or away from home (16°C).

  • 7

  • Blow hot air
  • Set your ceiling fan to spin clockwise to circulate the hot air downwards.

  • 8

  • Seal the leaks
  • Caulk, seal or weatherstrip drafts around doors and windows to reduce heating costs up to 30 per cent.

  • 9

  • The deal with ducts
  • About 20 per cent of your airflow is lost to leaky or disconnected ducts. Seal holes and cracks with mastic sealant or foil tape (avoid “duct" tape as it does not last long).

  • 10

  • Control humidity
  • Keep humidity levels at 30 per cent to 40 per cent to keep your home feeling warmer and more comfortable.
