A new high-efficiency gas furnace in Ontario typically costs between $2,900 and $5,500 installed, depending on the brand, efficiency rating, and complexity of the installation. HVAC Ontario currently offers $500 off furnace installations, with combo deals saving up to $1,000 when paired with an air conditioner. Financing from $49/month with $0 down is also available.

Top-rated furnace brands in Canada include Lennox, Goodman, Bosch, York, and Amana. HVAC Ontario installs all of these brands and will recommend the best model for your home size, budget, and efficiency goals. All installations come with a 10-year parts and labour warranty.

We do not recommend single-stage furnaces for Canadian homes. Most Canadian homeowners choose two-stage or variable-speed furnaces, and we recommend the same — since your furnace runs for roughly 8 months of the year, the added efficiency and comfort pay off. Two-stage furnaces adjust output for better efficiency, while variable-speed furnaces modulate continuously for the most consistent temperatures and quietest operation.

A hybrid system combines a cold-climate heat pump as the primary heating source with a gas furnace as backup. The heat pump handles most heating days efficiently using electricity. When temperatures drop below the heat pump's optimal range, the furnace automatically takes over. This combination reduces gas consumption by 30–50% while ensuring reliable heat even at -30°C.

Most furnace installations in Ontario take 3–5 hours for a standard replacement. HVAC Ontario offers same-day installation for most models, and our technicians carry a full inventory so there are rarely delays due to parts. We also remove and dispose of your old furnace at no extra cost.

All furnaces installed by HVAC Ontario come with a manufacturer's parts warranty of up to 10 years. Extended labour coverage of up to 10 years is also available, giving you complete protection against repair bills. The Lifetime No Hassle Unit Replacement warranty is included on our Gold and Platinum combo packages.
