How to check a heat pump contractor in Ontario when there is no heat pump licence

Homeowners reasonably assume that a trade this expensive and this technical has one licence behind it, so checking a contractor is a matter of asking to see it. Ontario does not work that way for heat pumps.

What exists instead is regulation of the parts. The electrical side of a heat pump installation has to be carried out by a licensed electrical contractor, and the job has to be notified to the Electrical Safety Authority, which is where your certificate of inspection comes from. Work on gas appliances requires a TSSA-certified gas technician, which matters on a dual fuel job where the furnace stays. Refrigerant handling has its own certification requirement. Whether a municipal building permit applies depends on the scope of the work.

None of that adds up to a single credential that says this company installs heat pumps well. It says specific tasks have to be done by specific trades. So when a company's marketing puts the words "insured" and "fully covered" in front of you, the useful question is not whether they are true. It is which permit or trade qualification is required for your job, who holds it, and who is going to show it to you.

Directories, including this one, put badges on listings, and the badges are easy to over-read. It is worth knowing exactly what each one on this site means, because we designed them to mean as little as they truthfully can.

"Heat pump work confirmed on their website" means one narrow thing: we read that company's own website and it says it does heat pump work. It is not an inspection and no company can ask for it. 351 of the 626 businesses listed here carry it today.

The second badge, the one about the province's rebate programme, means the company appears on that programme's own public contractor directory. That is a membership fact. The programme states that Enbridge Gas and the IESO do not endorse any of the contractors on it, and neither do we. 189 of the businesses here matched a row on that register when it was read on 2026-08-03.

Most usefully: a listing with no badge at all is not an accusation. It usually means the company's website does not mention heat pumps either way, or there is no website to read. Plenty of those firms fit heat pumps. The site leaves the space empty rather than printing a label it cannot support.

HeatPumpIndex does not check anyone's licensing or insurance, and it says so on its methodology page. A directory that tells you a company has been checked, without saying who checked it or against what, is telling you nothing you can act on.

Given all that, here is what actually moves the odds in your favour, in rough order of value for the time it takes.

Ask for two or three heat pump installations they finished nearby in the last two winters, and call those homeowners. Nearby and recent both matter: a crew can change entirely inside a year, and a heat pump's real test is a cold snap rather than an August afternoon.

Ask who is doing the electrical work and who files the ESA notification. This is a fact with a paper trail at the end of it, so an evasive answer is itself the answer.

Ask for proof of liability insurance and WSIB clearance directly from the contractor, in writing, rather than accepting a line on a website. A company that carries them can produce them in a day.

Read the newest reviews first rather than the average. A high average built over ten years describes a business that may not exist in its old form. Look at what people said in the last six months, and at what the company says back.

And get the scope in writing before the price. Almost every dispute in this trade is a disagreement about what was included, not about the number.

Since the point of this article is that you should ask directories what they actually know, it is fair to say what this one does.

Every listing here comes from public data: a Google Business Profile, the company's own website, and Ontario's rebate contractor directory. Rankings come from one published score out of 100 per company: 45 of it from Google reviews, which weighs review volume alongside star rating so a perfect score on three reviews does not outrank a strong one on three hundred, 30 from what the company states on its own website, and 25 from its website and record. Every row of that arithmetic is printed on the company's own profile page. Nothing can be bought.

Where a profile shows a quote from a company's website, that text is scraped and left exactly as found, ragged edges included, with the field it came from named underneath. A tidied quote would be our writing presented as theirs.

Where the site has nothing, it says nothing. There is no form on this site, no lead is passed on, and no company pays to appear. You call the business directly, which is also why it is worth doing the checks above yourself.
