5 Best Air Conditioner Repair in Toronto (2026)

Independently ranked by our review of ratings, reviews and reputation · How we chose

By Brad Smith, Home Services Expert · ✓ Data verified July 2026 · 8 min read

The AC dies on the one 34-degree day of the summer, obviously. Air conditioner repair in Toronto covers everything from decades-old national HVAC brands to smaller, technician-driven local shops, and the companies on this page carry 3,244 reviews between them. Reliance alone accounts for 2,178 of those, so size and reputation don't always point to the same name.

Short answer: Reliance Heating, Air Conditioning & Plumbing leads by review volume at 4.7 stars across 2,178 reviews, backed by more than 60 years in the HVAC business nationally. Dr HVAC and Plumbing (Toronto) (4.9, 492 reviews) posts the strongest rating among the larger providers, while Climax Heating & Air Conditioning (4.9, 129 reviews) is the smaller, technician-driven standout.

Our five picks, reviewed

#1 Overall🕑 Open 7 days↩ Responds to reviews

Reliance Heating, Air Conditioning & Plumbing

4.72,178 Google reviews

Reliance is a national home comfort company with more than 60 years of history, offering air conditioner repair, installation, and rentals alongside furnace, heat pump, water purification, and plumbing services from its Front Street Toronto office.

Reviews describe both AC and furnace work, along with plumbing callouts handled by the same company.

What people praise

Advisors like Salma and Charlie specifically praised for clear, patient explanations of options
Technicians consistently described as knowledgeable and courteous during installs
Follow-up service after installation praised by multiple reviewers
One team can handle HVAC and an unrelated plumbing issue in the same visit

Worth knowing

Rating sits a shade below the smaller, more specialized companies on this list, worth weighing if you want the most hands-on, technician-led experience

Dr HVAC and Plumbing (Toronto)

4.9492 Google reviews

Dr HVAC and Plumbing (Toronto) is based in East York and covers furnace and AC repair, installation, and maintenance, plus fireplace inspection and plumbing work. Reviews describe repeat customers using the company for annual checkups who then called them back for bigger jobs, like a full furnace replacement, when something failed. Technicians Seth, Adam, and NJ show up by name across multiple reviews for thorough, patient visits.

What people praise

Technicians praised for going beyond the original callout, including fixing an unrelated fireplace issue
Repeat customers specifically note consistently strong service across multiple visits
Clear communication and text updates before technician arrival
Same-day parts runs mentioned when the first visit didn't have what was needed

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

4.6359 Google reviews

1Click Energy Solutions, headquartered on Bay Street in Toronto, focuses heavily on heat pump installation and electrification rather than straightforward AC repair specifically. Worth noting: several reviews we found reference customers in Nova Scotia and Newfoundland rather than Toronto itself, suggesting this business serves a national footprint beyond its Toronto head office rather than operating as a purely local repair shop. Reviewers consistently name Brandon and Dylan as their main points of contact.

What people praise

Advisors Brandon and Dylan praised repeatedly for patient, responsive follow-up
Heat pump installs described as clean and efficient, including full cleanup afterward
Proactive monitoring offered after install, one reviewer specifically notes
Financing and rebate guidance mentioned as part of the sales process

Worth knowing

Reviews we read skew toward heat pump installation rather than straightforward air conditioner repair specifically; confirm they handle a simple AC fix before assuming that's their focus

Climax Heating & Air Conditioning

4.9129 Google reviews

Climax Heating & Air Conditioning is a Bloor Street West HVAC contractor covering furnace repair, air conditioning, and water heater services across the GTA. Nearly every review names the same technician, Sam, describing fast diagnosis and same-day or next-day fixes, including during a major storm when a furnace failed. It's a smaller operation than Reliance or Dr HVAC, with a more consistently personal, single-technician feel running through the reviews.

What people praise

Technician Sam named in nearly every recent review for speed and clear explanations
Same-day emergency response confirmed during a major storm
Transparent pricing specifically praised
Parts sourced and returned quickly when not on the truck already

Express Comfort Air Inc

4.986 Google reviews

Express Comfort Air handles residential and commercial HVAC and refrigeration work, including furnace installs, AC repair, and commercial walk-in cooler and freezer service. It's the newest and smallest company on this list by review count, but its site claims over 800 service calls and 100 installations completed in 2025 alone. Reviews consistently name technician Karan (also spelled Karam) for furnace and AC work.

What people praise

Technician Karan named specifically for professionalism and efficient diagnosis
Handles both residential AC repair and small commercial refrigeration under one roof
Responsive scheduling, including during a winter storm, per one reviewer
Transparent about parts and pricing before work starts

Worth knowing

Smallest review base on this list at 86, so the track record is thinner than the larger competitors

Watch: 5 Best Air Conditioner Repair in Toronto (2026)

How we scored these HVAC companies

Rating is each business’s live Google average. Review volume shows how many customers actually left feedback, measured as a percentile against other HVAC companies in Toronto. Confidence combines both, rewarding a strong rating that’s backed by real volume over a handful of reviews. Recency checks how recently people were still reviewing. None of this can be bought or adjusted by the business.

How much does air conditioner repair cost in Toronto? (2026)

AC repair costs in Toronto depend on the fault, whether it’s a simple part replacement, a refrigerant issue, or a full unit failure, and on the brand and age of your system. None of the five companies above publish a flat repair rate, so ask for a diagnostic fee upfront and get a written quote before authorizing anything beyond the initial callout.

Air conditioner repair across the GTA

Between downtown Toronto, East York, and the wider Greater Toronto Area these five companies cover, there’s a genuine local option for AC repair almost anywhere in the city, plus Reliance and 1Click’s broader regional reach if you’re further out.

What to ask before you hire an AC repair company

Is there a diagnostic fee, and is it credited if I go ahead with the repair?
Do you carry parts for my specific brand on the truck, or will you need to order them?
What’s the warranty on the repair itself?
Can you give me a same-day or next-day appointment if my AC is out during a heat wave?
Is my system worth repairing, or should I be thinking about replacement?
Are you licensed and insured for refrigerant handling?

Frequently asked questions

Are these rankings paid?

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

How did you choose these five?

We compared HVAC companies handling air conditioner repair in Toronto on their live Google rating, review volume, and recency, then read the review text for recurring themes.

How often is this page updated?

We last verified this data in July 2026. Ratings and review counts change over time, so treat this as a snapshot.

Should I choose a large company or a small local one?

Larger companies like Reliance offer more backup and financing options, while smaller, technician-driven shops like Climax often mean more consistent, personal service. Both approaches show up well in the review data here.

Is it worth repairing an old AC unit or replacing it?

It depends on the age and the specific fault. Ask whoever you call for an honest opinion on repair versus replacement cost before committing to a major repair on an older unit.

The bottom line

Reliance is the safest default if you want a large, established provider with backup and financing options. If you’d rather deal with the same technician start to finish, Climax Heating & Air Conditioning’s consistently personal service is worth the call instead.
