Toronto's family-run heating & cooling crew. Furnace repair, maintenance plans, central AC, and radiant floor heating — installed and fixed by our own people, never subcontracted.
Call the shop(555) 010-2030Therm Tech HVAC is a family-owned heating and cooling company in Toronto. We work on furnaces, central air conditioners, and hydronic radiant floor systems — and we do every bit of it ourselves. No subcontractors. No hand-offs. No strangers in your basement. When you call, you talk to someone who has actually put their hands inside a furnace like yours, in a house like yours, on a street like yours.
Six things, done properly. If your problem isn't on this list, call anyway — if it's heating or cooling, it's probably ours.
When the heat quits mid cold snap, you don't need a lecture — you need it fixed. We repair forced-air furnaces from all major brands and carry common parts on the truck, so most calls end the same day.
A furnace with a yearly checkup runs cleaner, breaks down less, and keeps its warranty valid. Our plans cover a full fall tune-up: inspection, cleaning, filter change, and a written report you can actually read.
We size your new system from your home's real cooling load, not a rule of thumb. Install day includes full commissioning, a thermostat walkthrough, and a startup checklist we leave with you.
Warm air, weak airflow, ice on the lines — we trace the actual cause instead of guessing. Refrigerant charge, capacitors, blower motors: diagnosed properly, fixed right the first time.
Boilers, in-floor loops, and zone controls are our specialty, not a sideline. We install and service hydronic systems that warm tile and concrete evenly, room by room.
No heat in January is an emergency, and we treat it like one. Call the line, talk to a person, and get a straight answer about when we'll be at your door.
Toronto weather doesn't negotiate. Here's how a year with us usually goes.
This is when we earn our name. Fall tune-ups before the first freeze, fast no-heat response when it hits −20, and honest advice when a twenty-year-old furnace is done — repair it or replace it, we'll tell you which makes sense.
Spring AC checkups, new central air installs sized to your actual home, and repairs when the old unit gives up in a July heatwave. We commission every install like it's our own house.
Hydronic in-floor heating design, install, and service — plus maintenance plans that keep furnaces and ACs out of trouble year-round. One crew, one phone number, the whole system covered.
Serving Toronto and surrounding areas. If you're inside this ring, we're your crew. Just outside it? Call — we'll tell you straight whether we can make it.
The paperwork matters when someone's working on gas and high voltage in your home. Ours is in order, and we'll show it before we start.
Full liability coverage and the right tickets for gas-fired equipment. Ask to see them — we like that question.
Every gas installation and repair follows Ontario's Technical Standards & Safety Authority requirements. No exceptions, no grey areas.
Trade certifications will be displayed here once verified.
Same crew, same standard — whether it's your bungalow in Scarborough or your shop on the Danforth.
A cold house in January is an emergency. Call now — you'll talk to a person, not a menu, and we'll give you a straight answer about when we can be there.
Most of our work comes from neighbours telling neighbours. Verified reviews will appear here.

Four steps. No surprises between them.
Tell us what's happening — weird noise, cold rooms, dead unit. We ask a few questions and book a visit window that suits you.
We find the actual problem and give you a fixed price before any work starts. You approve it, or we shake hands and leave.
The people who quoted it are the people who fix it. No subcontractors, no hand-offs mid-job.
Everything runs, everything's tested, and we show you what we did. The work area is left clean — that's the rule.
You'll know the price before we lift a wrench. We diagnose first, then quote a fixed number for the repair — no hourly meter running while you watch. Most single-visit furnace and AC repairs cost a few hundred dollars; if the fix isn't worth it on an old unit, we'll say so and quote the replacement instead.
Call (555) 010-2030 or send the quote form below — a real person answers. Tell us what's going on and we'll book a visit window. For no-heat calls in winter, say so upfront: those jump the queue.
We run standard weekday hours, and no-heat emergencies get priority any day. If your heat is out in January, the day of the week doesn't matter — call the line and we'll get you sorted as fast as the roads allow.
Toronto plus eight surrounding towns: Scarborough, North York, Etobicoke, Mississauga, Vaughan, Markham, Richmond Hill, and Brampton. If you're just outside the ring, call anyway — we'll tell you straight whether we can reach you.
Never. Every job is done by our own crew — that's been the rule since day one, and it's why most of our customers come back and send their neighbours.
Tell us what's going on. We'll reply with a visit window and a straight answer — usually the same day.
