"Most heating companies sell you a new furnace. We'd rather fix yours — and tell you honestly when it's time to let it go."— The Therm Tech way, since day one
Two ways to work with us. Every price below is marked Sample — your fixed quote comes after we see the actual job, and it never moves after that.
Sample figures shown for illustration on this concept page. Real quotes are fixed, in writing, and approved by you before any work begins.
Six services. No filler, no "solutions" — just the work, described the way we'd describe it over the phone.
Forced-air gas furnaces from all major brands, diagnosed properly and repaired the same visit whenever parts allow. Fixed price quoted before we start.
A yearly fall tune-up — inspection, cleaning, filter change, written report. Keeps the system efficient, the warranty valid, and winter surprises rare.
New central air sized from your home's actual cooling load. Installed, commissioned, and walked through with you on day one — quiet enough to forget.
Warm air, weak airflow, ice on the lines — traced to the real cause, not guessed at. Refrigerant, electrical, airflow: all of it.
Our specialty: boilers, in-floor loops, and zone controls, designed and installed for even warmth under tile and concrete, room by room.
Heat out in January? That's the front of the line. A person answers, you get a real arrival window, and we roll with parts on board.
Serving Toronto and surrounding areas — nine towns, one crew.
Most of our work arrives by word of mouth. Verified customer reviews will appear here.
Toronto gives us about four months of furnace weather, three months of AC weather, and five months of "better check it now."
Fall tune-ups before the first freeze, fast no-heat response at −20, and straight talk when a twenty-year-old unit is done — repair or replace, with the math shown.
Spring AC checkups, right-sized central air installs, and repairs when the old unit quits in a July heatwave. Commissioned like it's our own house.
Hydronic floor heating design and service, plus maintenance plans that keep both systems out of trouble. One crew, one number, the whole system.
Gas and high voltage deserve more than a handshake. Ours are current — ask, and we'll show them before we start.
Full liability coverage and proper certification for gas-fired heating equipment.
All gas work follows Ontario's Technical Standards & Safety Authority requirements.
Trade certifications will be displayed here once verified.
Same crew, same standard — bungalow in Scarborough or shop on the Danforth.
A cold house in January is an emergency. Call now — a person answers, and no-heat calls jump the queue.
Describe what's happening. We ask a few questions, book a visit window.
The real fault, then a fixed price. Approve it or we part as friends.
Same people who quoted it. Never subcontracted, never handed off.
Everything runs, you see what we did, the place is left clean.
You'll know the number before we start. Diagnose first, then a fixed quote — no running meter. Most single-visit repairs land in the low hundreds; if an old unit isn't worth it, we'll show you the math and quote the replacement.
Call (555) 010-2030 or send the form below — a person answers during the day. Mention "no heat" in winter and you jump the queue.
Weekdays for planned work; no-heat emergencies any day. A cold house in January beats any calendar — call and we'll get there as fast as the roads allow.
Toronto plus eight towns: Scarborough, North York, Etobicoke, Mississauga, Vaughan, Markham, Richmond Hill, Brampton. On the edge? We'll give you a straight answer.
Never. Family-owned means our name is on every job, so our own crew does every job.
Tell us what's going on. We reply with a visit window and a straight answer — usually the same day.
