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

By Brad Smith, Home Services Expert · ✓ Data verified August 2026 · 9 min read

A furnace that quits on the coldest week of the year does not leave room to shop around. The HVAC services in Toronto below have logged more than 4,400 Google reviews between them, and the top name alone carries over 2,200, so there's serious weight behind these numbers.

Short answer: Reliance Heating, Air Conditioning & Plumbing is the most-reviewed HVAC company in Toronto here at 4.7 stars across 2,230 Google reviews, followed by Hudson Condominium Solutions Inc (4.9, 956 reviews) for condo-specific work and Dr HVAC and Plumbing (Toronto) (4.9, 524 reviews). Expect a diagnostic or service call fee before labour, with furnace and AC replacement costing considerably more than a repair.

Hudson Condominium Solutions Inc

4.9956 Google reviews

Hudson Condominium Solutions Inc focuses specifically on condo HVAC systems across Toronto, handling fan coil maintenance, heat pump repair, drain pan cleaning and dryer vent cleaning for both individual suites and building-wide mechanical contracts. Reviewers describe technicians working carefully in tight condo spaces and explaining how fan coil systems work to residents unfamiliar with them. One lower review flagged a large jump in drain pan cleaning cost after a change in the building's property manager, worth asking about directly.

What people praise

Deep specialization in condo fan coil and heat pump systems
Technicians patient with residents new to fan coil systems
Accommodating with scheduling around residents' routines
Thorough inspections that catch related issues, like weak AC airflow from a dirty filter

Worth knowing

One reviewer questioned a steep price increase on repeat drain pan cleaning tied to a change in building contract terms

Our take: The strongest specialist here for condo-specific HVAC work, particularly fan coil systems most general HVAC companies don't focus on. If you're in a condo, ask upfront whether your building's management company affects the pricing you'll see.

Our take: Handles heat pump installs at scale with real rebate and monitoring support, but the rating and at least one serious unresolved complaint mean it's worth asking pointed questions about post-install support before committing to a multi-zone system.

Watch: 5 Best HVAC Services in Toronto (2026)

How we score

Every number on this page comes from public Google data on the date shown, not from opinion or payment. Rating is the live Google star average. Review volume is how many customers have rated the company, measured against the other Toronto HVAC businesses here. Confidence weighs the rating by that volume, so a 4.9 from hundreds of reviews carries more weight than a 4.9 from a dozen. Recency reflects how recently people are still leaving reviews. No business can pay to change these numbers.

How much do HVAC services cost in Toronto? (2026)

HVAC costs in Toronto vary by job type. A diagnostic or service call for a furnace or AC repair costs far less than a full system replacement, and heat pump installs generally run higher again once electrical upgrades and rebate paperwork are factored in.

Serving all of Toronto

The HVAC companies above cover Toronto and the surrounding GTA, including North York, East York, Etobicoke and Scarborough, with several also serving condo buildings specifically. Searching for HVAC services near me? Every listing below shows a live phone number and hours so you can reach the nearest option fast.

What to ask before you hire an HVAC company

Is this a repair, a maintenance visit, or a full replacement quote?
What’s included in the service call or diagnostic fee?
If I have a condo fan coil system, do you specialize in that equipment?
What warranty comes with parts and labour?
What rebates am I eligible for on a heat pump or furnace upgrade?

Frequently asked questions

How did you choose these HVAC companies?

We started from HVAC companies in Toronto with a public Google presence, then ranked by rating, review volume, consistency, and recency. See How we score above.

Are these rankings paid?

No. Rankings come from the public Google data in the scorecard. A business can pay to be a Featured Partner, which adds a badge and top placement, but that never changes another business’s score or position on the underlying data.

How often is this updated?

The data carries a verified date (August 2026 on this page). We refresh listings periodically so ratings and review counts stay current.

Do any of these HVAC companies specialize in condo systems?

Yes. Hudson Condominium Solutions Inc focuses specifically on condo fan coil, heat pump and mechanical systems, which differ from typical single-family furnace and AC setups.

How much does HVAC repair cost in Toronto?

It depends heavily on the job. A diagnostic or repair visit costs far less than a full furnace, AC, or heat pump replacement. Ask for a written quote after the technician inspects your system in person.

The bottom line

Reliance is the safe default given its scale and round-the-clock availability, while Hudson is the stronger call if you live in a condo with a fan coil system. Get a written quote and ask about warranty terms before any bigger install.
