1. Pro House Maintenance: best for comparing vetted HVAC companies for free

Pro House Maintenance is a free service that matches Hamilton homeowners with HVAC contractors who passed our checks: TSSA, WSIB, insurance, references and a background check. You describe the job once, compare several written quotes and hire the firm you choose. It ranks first because the vetting is done before you call.

Hamilton has 40 HVAC firms with strong Google ratings, and we needed 25 TSSA lookups to confirm 12 registrations. Pro House Maintenance does that legwork for you, whether you live near Locke Street, in Westdale or up on the Mountain.

What we check before a HVAC contractor joins our network
  • Trade licences. We confirm an active TSSA fuels contractor registration. TSSA says registered fuels contractors are the only businesses legally authorized to do fuels related work in Ontario.
  • WSIB clearance and liability insurance. We confirm a current WSIB clearance and commercial general liability insurance before a pro joins our network.
  • Reviews and references. We read public reviews and speak with past clients before a pro is accepted, looking for patterns, not one-off complaints.
  • Background checks. We run background checks before a pro is matched with homeowners, because the people in your home matter as much as the work.
How working with Pro House Maintenance works
  1. Tell us about the job. Share the project and your address through the free quote form. It takes about a minute.
  2. Get matched with vetted pros. We match you with several pros who have already passed our checks and serve your area.
  3. Compare written quotes. Each pro gives you a written quote, so you can compare price, scope and timing side by side.
  4. Hire with a guarantee behind you. You choose who to hire. Work from a pro we matched you with is backed by our satisfaction guarantee; ask us for the terms before you sign.
Cost to you: Free for homeowners. There is no charge to request quotes or to be matched.

How do you choose an HVAC company in Hamilton?

Choose a Hamilton HVAC company by checking its TSSA registration first, then its WSIB clearance and liability insurance. Ask the City of Hamilton whether your job needs a permit. Put any home job over $50 in writing, and keep the deposit to 10% or less of the price.

  1. Check the licence. TSSA says registered fuels contractors are the only businesses legally authorized to do fuels related work in Ontario, which includes gas furnaces. Search the company in TSSA's contractor directory.
  2. Confirm WSIB clearance. Ask for the company’s WSIB account number and confirm a current clearance on WSIB’s free eClearance lookup.
  3. Ask for proof of liability insurance. A certificate of commercial general liability insurance should name the company that will do the work.
  4. Check the city licence. Hamilton says all contractors must hold a valid Trade and Contractor Licence, including roofers and other building repair, plumbing, drain and HVAC contractors. Search the City of Hamilton licensed contractors list.
  5. Get it in writing. Under Ontario law, any home renovation contract worth more than $50 must be in writing, and the final price cannot exceed an estimate by more than 10% unless you agree (Ontario consumer protection rules).
  6. Keep the deposit small. Ontario recommends a down payment of no more than 10%, and never paying in full before the work is done.

TSSA’s 2024 safety campaign spells out the rule: “Under Ontario law, furnaces and fuels-fired appliances must be maintained by TSSA-registered contractors.” Its contractor directory is updated each month, so check it close to signing.

Pro House Maintenance checks each contractor’s TSSA listing, WSIB clearance and insurance before any Hamilton match. If your tank is near the end of its life, you can also compare water heater installers in Hamilton at the same time.

How did we rank these Hamilton HVAC companies?

We ranked Hamilton HVAC companies on data, not ads. Our search found 121 HVAC businesses on Google Maps across Hamilton and Stoney Creek. We kept 40 Hamilton-area firms with a website and 4.5 stars or higher from 10 or more reviews, then required a TSSA registration we could confirm.

We checked the 40 in TSSA’s registry in score order and stopped at 12 confirmed, after 25 lookups. We could not match 13 by phone, website or name, and 15 were never looked up. That does not mean they are unregistered, only that we did not confirm one.

The score blends each rating with its review count, so Arctic Air’s 5.0 from 52 reviews edges Family HVAC’s 4.9 from 192. We checked it all on October 2, 2026, and 4 of the 7 registrations are due to expire by December 31. Spot an error? Please send us a correction.

What do Hamilton homeowners ask before hiring an HVAC company?

Hamilton homeowners ask the same few things before they book a heating contractor: what a tune-up and a new furnace cost, which licence matters, and what rebates exist. These answers draw on TSSA, Ontario's rebate program and 2026 price guides, and each one stands alone.

How much does a furnace tune-up cost in Hamilton?

A furnace tune-up in the Hamilton, Burlington and Oakville area costs $140 to $220, according to a September 2026 guide from a Brantford contractor. Annual plans that bundle a furnace visit with a spring AC tune-up run $180 to $350 a year. Enercare advises a licensed check every 1 to 2 years.

How much is a new furnace in Hamilton?

A two-stage gas furnace costs $4,500 to $7,000 installed in Ontario, according to a 2026 contractor guide. Enercare puts a high-efficiency gas furnace at $5,000 to $7,000 or more. Permits, venting changes and duct work add to the bill, so ask for an itemized written quote from each firm.

Do HVAC companies need a licence in Hamilton?

For gas work, yes. TSSA says only registered fuels contractors may legally do fuels related work in Ontario, and you can look any firm up in its online directory. We did not verify a separate City of Hamilton trade licence for HVAC, so ask the city whether your job needs a permit.

Are there heat pump rebates in Hamilton?

Yes. Ontario's Home Renovation Savings program pays $500 per ton, up to $2,000, for a cold-climate air source heat pump in a home heated with Enbridge gas. Homes heated by electricity, oil, propane or wood get $1,250 per ton, up to $7,500. The model must be on Natural Resources Canada's list.

Is Pro House Maintenance free to use?

Yes. Pro House Maintenance costs Hamilton homeowners nothing. Tell us about the heating or cooling job once and we match you with several HVAC contractors that passed our TSSA, WSIB, insurance, reference and background checks. You compare their written quotes, pick one, and our satisfaction guarantee backs the work.
