- Confirm they carry a minimum of $2 million in commercial liability insurance.
- Get at least three written quotes that include equipment model numbers, warranty terms, and permit costs.

Frequently Asked Questions \u2014 HVAC Contractors in Ontario
How much does a new furnace cost in Ontario in 2026?
A new furnace installed in Ontario in 2026 costs $3,500–$6,500 for standard efficiency (80% AFUE) or $4,500–$8,000 for high-efficiency (96%+ AFUE). High-efficiency models qualify for Greener Homes Grant rebates up to $5,000, making the net cost competitive with standard units.
Do HVAC contractors need a TSSA registration in Ontario?
Yes. Any contractor performing gas work—furnace installation, boiler repair, water heater service—must hold a valid TSSA registration. Verify at tssa.org. Hiring unregistered contractors voids equipment warranties and violates Ontario law.
What is the difference between a heat pump and a furnace?
A heat pump transfers heat from outdoor air and can both heat and cool your home. A furnace burns natural gas to produce heat. Heat pumps are more energy-efficient but may need a gas backup below -20°C. Many Ontario homeowners are switching to hybrid systems that combine both.
How often should I service my HVAC system?
Service your furnace annually in the fall and your AC annually in the spring. Regular maintenance extends equipment life by 5–10 years, maintains warranty coverage, and can reduce energy bills by 15–20%. Most Ontario HVAC companies offer maintenance plans for $150–$300 per year.
Is the HVAC directory free to use?
Yes. Homeowners and business owners can browse, compare, and contact any HVAC contractor in our directory at no cost. There is no registration or sign-up required.
