HVAC Service Built for Toronto Homes
Toronto is a city of contrasts, from century homes in The Annex and Leslieville with tight, original ductwork to glass condos downtown that rely on ductless and fan-coil systems. EcoFrost has installed and repaired HVAC across all of it, and we size every system for the real building rather than a generic template.
We serve every corner of the city, including North York, Scarborough, Etobicoke, East York, The Beaches, High Park and the downtown core. Our technicians know Toronto's permit process and handle the paperwork so your install passes inspection the first time.
Credentials That Matter in Ontario
Anyone can call themselves an HVAC company. These are the credentials Toronto homeowners should verify before they hire anyone.
TSSA Certified Contractor
Ontario's gas-equipment regulator licenses our team to install and repair every residential gas system.
Authorized Lennox Dealer
We chose Lennox as our preferred partner because their efficiency and quiet operation lead the industry.
HRAI Member
Heating, Refrigeration and Air Conditioning Institute of Canada membership means our trade practices meet national standards.
G1 and G2 Gas Licensed
Every tech on our crew holds the gas licenses Ontario requires for residential furnace and water heater work.
Why Toronto Homeowners Pick EcoFrost
Six concrete reasons that show up on the invoice, not in the marketing.
Same-Day Dispatch Across Toronto
We staff for emergencies. Most service calls get a real arrival window in seconds, not a vague 8-hour bracket. Our trucks reach every part of Toronto, from downtown condos to North York, Scarborough and Etobicoke.
$0 Overtime Fees, Ever
Nights, weekends, holidays. Our rate stays the same. Other contractors charge 1.5x to 2x for after-hours calls. We do not, because emergencies do not pick business hours.
Flat-Rate Pricing in Writing
We diagnose first and quote before any parts go in. No surprise add-ons at the end. You see the full price in writing and approve it before we start the repair.
Rebate Paperwork Handled For You
The Ontario Home Renovation Savings Program and the federal Oil to Heat Pump Affordability program can stack to over $10,000 on some heat pump installs. We complete and submit every form on your behalf at no extra cost.
TSSA Red Tag Removal
If another contractor or the gas utility red-tagged your furnace, we offer a free second opinion and remove the tag the same day when the equipment is safe to operate.
10-Year Labour Warranty on New Installs
Our labour warranty doubles the typical industry coverage. Combined with the manufacturer's parts warranty, you are protected for a full decade after install.

Ecofrost installed a new air conditioner for us in late August. Our 23 year old AC finally gave out. Nisar quoted us a very good price on a Lennox. They were able to install it the next day. They were very professional and knowledgeable and we are very happy with the service that was provided. It is nice to have a great company that you can count on in the community.

I am extremely pleased with Nisar and his team for the professionalism, a mind for customer satisfaction, attention to detail and last but not least their focus on completing the job with precision and due care. Nisar came in with knowledge and patience to answer all my questions and got us the best deal on AC.

What an amazing experience with this company at a time where I was really helpless! My furnace finally went down after 22 years and this company took all my worries away! They responded immediately, came up with a plan and stuck to it by being on time, professional, friendly, kind, and patient.
