Common problems
Sound familiar?
These are the calls we take every week across Toronto and the GTA. Each one has a straightforward answer once someone qualified actually looks at it.
Enbridge shut off your gas
A red tag means no heat and no hot water until a licensed technician clears it. We respond across the GTA in two to four hours and restore most services within 24 hours.
Furnace or AC failed today
A dead furnace in January or a failed air conditioner in a July heat wave is not a next-week problem. We hold same-day weekday capacity and dispatch 24/7 in an emergency.
Rebates and options are confusing
Heat pump, dual fuel, or a straight furnace replacement? We model the numbers for your home, confirm rebate eligibility, and complete the paperwork for you.
You have been quoted without explanation
Every job gets a written quote before work starts, with the findings explained in plain language. No hidden fees, no pressure, and no scare tactics about heat exchangers.
We start with a proper diagnosis, then give you an honest recommendation. Book a free assessment

Why us
The contractor Toronto calls when the gas goes off
Best HVAC Toronto is a family-owned, full-service residential and commercial HVAC contractor with more than twenty years of combined crew experience in Ontario. Our technicians are TSSA G1/G2 certified, WSIB-covered, insured for $2 million, and background-checked.
What sets us apart is Enbridge Red Tag work. When the utility locks your meter, you need someone who can diagnose the fault, correct it, and sign the clearance on the same visit. That is our specialty, and it is why most of the red tags we attend have gas restored within 24 hours.
More about usEnbridge Red Tag specialists
Red tag compliance is what we are known for in Toronto. Type A and Type B tags, gas leak detection, cracked heat exchanger verification, venting corrections, and full re-certification, with most tags cleared and gas restored inside 24 hours.
TSSA G1/G2 certified, fully insured
Every technician holds a G1 or G2 gas licence, works under WSIB coverage, and is backed by $2 million in general liability insurance. We are an HRAI member and every technician is background-checked before they enter your home.
Whole HVAC lifecycle, one contractor
Furnaces, air conditioning, boilers, heat pumps, water heaters, gas lines, ductwork, air quality, and commercial systems. Residential and commercial work sits with the same crew, so nothing gets subcontracted out and forgotten.
Manufacturer-authorized dealer
Authorized for Lennox, Carrier, Trane, Bosch, Napoleon, and York. That means genuine parts, valid manufacturer warranties of 5 to 10 years, and warranty claims handled by us rather than left with you to chase.
Transparent, written pricing
Free on-site estimates for installations with no obligation, and a written quote before any work begins. The number you agree to is the number you pay, and financing is available on approved credit.
2-year labour warranty
Double the industry standard on labour, on top of manufacturer parts coverage. All work is performed to the Ontario Building Code and TSSA gas code, and we register your equipment warranty on your behalf.

Why it matters
How we compare to a typical Toronto HVAC company
Not every contractor diagnoses before they quote. Here is what that difference looks like in practice.
| Feature | Typical provider | Best HVAC Toronto |
|---|---|---|
| No-heat / gas emergency response | 1 to 3 days, or next available slot | 2 to 4 hours across the GTA, 24/7 for red tags |
| Before recommending a fix | Verbal estimate, replace first | Combustion analysis and load calculation before any quote |
| Quote format | Verbal estimate on site | Written fixed price before work starts |
| Labour warranty | 1 year, the industry standard | 2 years on every installation |
| Rebate paperwork | Left to the homeowner | Checked and filed by us |
Reviews
What our customers say
4.9 out of 5 from 150+ customer reviews
Enbridge red-tagged our furnace on a Friday night and shut off the gas. Best HVAC Toronto had a technician out within two hours, found the cracked heat exchanger, and had us re-certified and heating again the next morning. Calm, clear, and no scare tactics.
Replaced our 18-year-old furnace with a high-efficiency unit and walked us through the Ontario rebates. Written quote up front, no hidden fees, and the crew left the mechanical room cleaner than they found it.
Our AC died during the July heat wave. They came out same day, diagnosed a refrigerant issue, and had us cool again fast. Honest about repair versus replace, and they didn't push us into a new system.
We had a cold-climate heat pump installed for our Markham home. They handled all the rebate paperwork and it's kept us warm through the winter. Very knowledgeable about the dual-fuel setup.
Needed a gas line run for our backyard BBQ and outdoor kitchen. TSSA-certified, permits handled, pressure test done properly. Fair price quoted by run length. Would use again.
