Our top 10 hvac companies in Calgary

Calgary's winters push furnaces hard for five or six months a year, and a failure in January is a different kind of emergency than one in July. The city sits in Alberta, where HVAC contractors and gasfitters are licensed through Alberta Apprenticeship and Industry Training and the Safety Codes Council rather than a single provincial board, and permits for furnace and gas line work go through the City of Calgary or an accredited safety codes agency. Alberta doesn't require a homeowner to hire a licensed contractor for every repair, but any gas appliance work should be pulled under permit and performed by someone holding a current gasfitter certificate of qualification, since improperly vented gas equipment is a real carbon monoxide risk in a city where furnaces run nearly year-round. Calgary's housing stock spans postwar bungalows in the inner city to new-build subdivisions on the outskirts, and companies here tend to specialize either in older-home retrofits and duct reconfiguration or high-volume new-construction installs, which is worth knowing before you call for a quote.

How we chose the best hvac companies in Calgary

Read our full ranking methodology →

We ran two Google Maps searches ("HVAC contractor in Calgary, AB" and "HVAC company Calgary"), merged and deduplicated the results by Google place ID, and kept them in Google's own ranking order. Every company had to be operating, rated 4.5 stars or higher, with at least 50 Google reviews, a real working website, and a physical location inside Calgary's city limits. We then cross-checked each company's own website against its Google listing for licensing, warranty, financing and service-area claims. Companies do not pay for placement or for a better position on this list. Ratings and review counts were read on September 21, 2026, and this list was last reviewed on that date.

How to choose a hvac company in Calgary

  • Verify insurance and credentials

    Ask for a current certificate of insurance and confirm registration or licensing with the authority that issues it, not with the company.

  • Ask for a written estimate

    Scope, materials, removal, disposal and who pulls the permit should all be named on the page rather than agreed on the doorstep.

  • Compare multiple quotes

    Two or three bids on the same scope. A number far below the others usually means something has been left out of it.

  • Understand the warranty

    Separate the manufacturer's warranty on materials from the company's own warranty on the work, and get both in writing.

  • Ask who performs the work

    Find out whether the crew are employees or subcontractors, and who supervises them on the day.

  • Check recent local projects

    Ask for addresses or photographs of comparable jobs finished nearby in the last year or two.

  • Avoid high-pressure sales

    A discount that expires today, or a knock on the door after a storm, is a reason to slow down rather than sign.

  • Get everything in writing

    Change orders, timeline and payment schedule included, before the first payment changes hands.

Questions to ask before hiring

  • Are you insured, and can you send the certificate?
  • How long have you worked in this area?
  • Will you provide a written estimate with materials listed?
  • What warranty do you offer on the work itself?
  • Do you use subcontractors for this job?
  • Who handles permits and inspection?
  • What would you recommend here, and why?
  • How are unexpected costs handled once work starts?
  • What is the estimated timeline from start to finish?
  • Can you provide recent local references?

Red flags

  • No verifiable local business address or registration
  • Pressure to sign on the first visit
  • A demand for full payment up front
  • An offer to cover or waive your insurance deductible
  • Refusal to put warranty terms in writing
  • A quote that will not itemize scope

HVAC companies in Calgary FAQs

  • Do I need a licensed contractor to fix my furnace in Calgary?

    Alberta doesn't require every repair to go through a licensed contractor, but any gas appliance work should be performed by someone holding a current Alberta gasfitter certificate of qualification and pulled under permit with the City of Calgary, since improperly vented gas equipment is a real carbon monoxide risk.

  • How much does furnace maintenance cost in Calgary?

    Most companies on this list offer maintenance plans or membership programs, typically in the $15 to $20 a month range, covering an annual tune-up plus a discount on repairs. A standalone tune-up without a membership usually costs more per visit.

  • Why do Calgary furnaces need more frequent service than furnaces in milder climates?

    Calgary furnaces often run from September through May, putting far more operating hours on the system each year than in a milder climate, which is why several companies on this list offer year-round maintenance plans rather than a single annual check.
