Top 5 furnace tune-up tips


Seal the leaks

Don’t force your HVAC system to 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.


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 clean.


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.


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.


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 877-467-4724 or check out the contractor locator portal.

Is it time for a new furnace?

While high-efficiency units tend to have a higher purchase price, lower operating costs mean you will spend less over time.

Quiet Performance
Better warranty protection

Use less energy

Think about upgrading if:

The air in your home is too dry or dusty
Your system is more than 15 years old
It’s unusually noisy
Rooms served by the furnace are chilly
You need major parts replaced or repaired

Look for the high AFUE rating

The Annual Fuel Utilization Efficiency (AFUE) rating, found on the official Canadian EnerGuide label, is a measure of how efficient your furnace is. The higher the rating, the more efficient the model.
