It's the only business on this list offering a rent-or-buy model for water heaters specifically, alongside standard repair and replacement.

What people praise

Rent-or-buy flexibility on water heaters, a genuinely different option from a straight purchase
Home comfort advisors (Salma, Charlie named repeatedly) praised for walking customers through options clearly before any work starts
Deepest, most consistent review base of any business on this list at 2,181 reviews
24/7 availability referenced across multiple reviews, including weekend emergency plumbing

Worth knowing

Our take: It ranks first on the combination of scale, service breadth, and a rating that's held up across thousands of reviews. If you want the flexibility of renting a water heater instead of buying outright, this is the only option here offering that.

Extron Electric & Plumbing Ltd

5.0453 Google reviews

Extron Electric & Plumbing Ltd is a licensed electrical and plumbing contractor established in 2007, serving Brampton, Mississauga, Caledon, Vaughan, and the wider Toronto area. It handles both trades under one roof, which matters for jobs like a water heater replacement that sometimes needs an electrical adjustment alongside the plumbing work itself.

What people praise

Perfect 5.0 rating across 453 reviews
A replacement water heater job specifically praised for prompt response and clear explanation of the work before starting
Reasonable, competitive pricing repeatedly mentioned across different reviewers and different job types
One technician (Karan) named directly and praised across multiple, separate water heater and plumbing reviews

John The Plumber

4.8316 Google reviews

John The Plumber is a Downtown Toronto plumbing company offering same-day service for general plumbing and drainage issues, including sewer pipe lining and drain cleaning, positioning itself as available around urgent, same-day calls. It's a full-service plumber rather than a water-heater specialist specifically, so while water heater work falls within a general plumber's scope, we didn't find a review that names a water heater job directly in our sample.

What people praise

Same-day response consistently praised, including stepping in after another company left a job unfinished
Named technicians (Ryen, Geoff, Reza, Ashton) repeatedly credited for clear explanations of the problem and fix
Reviewers specifically note feeling comfortable having technicians in the home alone

Worth knowing

We didn't find a specific water heater job described in the reviews we reviewed; it's a full-service plumber, so confirm they stock the specific water heater type you need before booking

Our take: It ranks third at 4.8 across 316 reviews. A strong, well-reviewed general plumber, worth a call for urgent water heater trouble, just confirm availability of parts for your specific unit first.

Plumber To Your Door of Mississauga

5.0232 Google reviews

Plumber To Your Door of Mississauga is a licensed plumbing company covering the GTA, including Toronto, offering same-day emergency plumbing alongside planned installs. Unlike some of the others on this list, its reviews directly and repeatedly describe water heater replacement and tankless water heater installation work, not just general plumbing.

What people praise

Perfect 5.0 rating with zero reviews below 5 stars on file
Tankless water heater installs specifically described in detail, including mounting and connection testing
Standard water heater replacement work praised for thorough testing before the technician leaves
George named repeatedly across separate water heater and diagnostic jobs

1Click Energy Solutions (formerly 1Click Heating and Cooling)

4.6359 Google reviews

1Click Energy Solutions, formerly 1Click Heating and Cooling, is an HVAC contractor focused on heat pump installation and broader home electrification. Worth flagging directly: every review in our sample describes heat pump work, and the business's own site doesn't mention water heaters, so while it's included in this category, we found no direct evidence of water heater specialization to confirm alongside the other four.

What people praise

Advisors (Dylan Steinberg, Brandon Fenech) repeatedly praised for patient, responsive communication throughout heat pump installs
Follow-up support after installation specifically mentioned, including arranging a monitoring meter at no extra cost
Installation crews described as clean, professional, and thorough on cleanup

Worth knowing

No review or listed service in our sample confirms water heater work specifically; this looks like a broader HVAC and heat pump specialist rather than a water heater business
The lowest rating of the five (4.6), reflecting more mixed feedback than the top four

Watch: 5 Best Water Heater Services in Toronto (2026)

How we score water heater services

Rating is the live Google average pulled directly from each business’s profile. Review volume measures how many actual customers left a rating, weighed against the average, since a perfect score on a small sample carries less confidence than one built on hundreds. No business can pay to change these numbers, and where a listing showed up for this category without clear evidence of the specific service, we said so directly.

What water heater service costs in Toronto (2026)

None of the five businesses here publish a fixed price list, and cost depends heavily on tank versus tankless, gas versus electric, and whether you rent or buy, so we’re not going to invent a number. One real, structural difference worth knowing: Reliance offers a rent option that spreads the cost over time instead of one upfront purchase, which the other four on this list don’t offer.

Water heater services across Toronto

This list spans Downtown Toronto, Brampton, Mississauga, and the wider GTA, so most of these businesses cover Toronto proper as core territory rather than a stretch booking. If you’re searching for water heater services near me and need same-day help, confirm emergency availability directly, several of these businesses distinguish between standard scheduling and true 24/7 emergency response.

What to ask before you hire a water heater service

Do you offer a rent option, or is it purchase only?
Tank or tankless, and which one fits my household’s usage and space?
Is same-day or emergency service actually available, or just standard scheduling?
Does the quote include removal and disposal of the old unit?
Is a permit required for my install, and is that included in the price?
What warranty applies to the unit versus the labor?

Frequently asked questions

Are these rankings paid?

No. Rankings come from public Google data. A business can pay to be a Featured Partner (badge plus top placement), but that never changes another business’s score or position.

How did you choose these five?

We pulled the businesses that appear for this search in Toronto, then ranked by a blend of star rating, review volume, and how recently people are still leaving reviews. Where a listing lacked clear evidence of water heater work specifically, we flagged that directly.

How often is this page updated?

We refreshed this ranking in July 2026 using live Google data. Ratings and review counts shift over time, so treat the numbers here as a snapshot rather than fixed.

Should I rent or buy a water heater?

Renting spreads the cost over time and often includes maintenance, but you pay more over the long run than an outright purchase. Reliance is the only business on this list offering a rent option directly.

The bottom line

Reliance is the safe default for most people: the deepest track record in Toronto and the only rent-or-buy option on this list. If you specifically want a tankless install and a documented track record on that exact job, Plumber To Your Door of Mississauga has the clearest evidence of it.
