Upgrading to a high-efficiency furnace in Ontario can feel like a big investment, but is it worth it? If you’re a homeowner in Mississauga or anywhere in Ontario, you’ve likely heard buzz about these systems saving energy and lowering heating bills. Let’s break it all down.
What is a High Efficiency Furnace?
A high efficiency furnace operates at 90% AFUE (Annual Fuel Utilization Efficiency) or higher. That means 90 cents of every fuel dollar directly heats your home. The older units? They might only hit 60–70%, letting 30–40% of your fuel go up in smoke—literally, through the chimney.
Are New Furnaces More Efficient?
Absolutely. Modern furnaces are equipped with modulating gas valves, variable speed motors, and sealed combustion. These features optimize both comfort and efficiency. Compared to older units, new electric furnaces are more efficient and require far less maintenance.

Are Electric Furnaces Energy Efficient?
They sure are—especially in well-insulated homes. Electric furnaces have nearly 100% efficiency, meaning no fuel is wasted. The trade-off is energy costs. In Ontario, natural gas is cheaper per BTU than electricity. So while electric is technically more efficient, it might not always be more cost-effective.
Are High Efficiency Furnaces Quieter?
Yes, and it’s a noticeable difference. High efficiency furnaces come with multi-speed blowers and sound-dampening insulation, which means less rumble and more peace. If your current unit sounds like a freight train, it’s probably time to consider upgrading.
Can You Still Buy Mid Efficiency Furnaces in Canada?
Not anymore. Since 2010, Canada has phased out mid-efficiency furnace installations. So, unless you’re buying a used unit (not recommended), you’ll be shopping from high-efficiency models only.
Can You Vent a High Efficiency Furnace Through the Chimney?
Short answer: nope. These furnaces use PVC piping for sidewall venting, not traditional chimneys. That’s because the exhaust is cooler and needs to be safely vented outside without causing moisture damage.
If your current setup only allows chimney venting, a liner or upgrade to sidewall venting may be needed.
Are There Any Government Rebates for High Efficiency Furnaces?
Yes, Ontario residents can take advantage of several rebate programs. These change frequently, but currently include options like:
- Canada Greener Homes Grant (up to $5,000)
- Enbridge Gas Rebate Programs
- Home Efficiency Rebate Plus (HER+)
Always check with a certified HVAC provider for the latest info, or see what rebates are currently available at HVAC Group Mississauga.

High efficiency furnaces are ideal for:
- Homes with rising energy costs.
