HVAC · FURNACE INSTALLATION
No heat in January? We handle same-day no-heat emergencies across the GTA. Most furnaces in Toronto homes reach end-of-life at 15–20 years — and that's when you should be planning a 96%+ AFUE high-efficiency upgrade, not scrambling. Gas, electric, or dual-fuel — we run a Manual J load calculation on every install so the unit is sized for your home, not a rule of thumb. TSSA licensed gas fitters. Greener Homes Grant and Enbridge rebates filed for you.
Whether you're replacing a 20-year-old mid-efficiency unit or speccing a dual-fuel system paired with a cold-climate heat pump, Caspian installs every major furnace type — sized with a proper load calculation and registered for full manufacturer warranty.
96%+ AFUE condensing units from Lennox, Carrier, Trane, and Goodman. Sealed combustion, PVC venting, and quiet ECM blowers as standard.
Variable-capacity systems that match output to load — quieter operation, more even room temperatures, and the lowest gas bills you'll ever see.
For homes without gas service. Clean, simple, and reliable — and a natural fit for retrofits paired with rooftop solar or a future heat pump.
High-efficiency furnace paired with a cold-climate heat pump. Heat pump handles the shoulder seasons; furnace kicks in below -15°C. Best of both.
Packaged RTUs for retail, warehouse, and small commercial. Sizing, curb adapters, gas piping, and TSSA-compliant venting — done end to end.
Same-day replacement available in many cases — we stock common sizes from the major brands. Old unit hauled away, new unit registered, gas safety check signed off.
One-size-fits-all furnace sizing is the single most common reason Toronto homeowners overpay for heat — and burn through equipment early. Here's how we do it properly.
Most furnaces installed in older Toronto homes are oversized — picked by a tonnage rule-of-thumb based on square footage alone, with no consideration for the actual heat loss of the building. It's quick. It's also wrong.
An oversized furnace short-cycles: it turns on, blasts heat for a few minutes, hits the thermostat, and shuts off. Then it does it again, and again. Every cycle wastes fuel on warm-up, wears out the igniter and inducer motor, and leaves cold spots in the rooms farthest from the register.
Caspian runs a Manual J load calculation on every install — the ACCA-standard heat-loss/heat-gain method that accounts for square footage, insulation R-value, window U-value, air infiltration rate, building orientation, and local design temperature. It takes longer than guessing. It also gives you the right answer.
The right-sized furnace runs longer at lower fire, which means quieter operation, more even heat across the house, and meaningfully lower gas bills. It also keeps your warranty valid — every major manufacturer (Lennox, Carrier, Trane, Goodman) requires proper sizing as a condition of coverage.
Furnaces almost always give you warning signs before they die. Catch them and you can plan a winter-ready replacement — ignore them and you'll be calling at 11pm in a -20°C snap.
Typical residential furnace lifespan is 15–20 years. Past the 15-year mark, efficiency drops, parts get harder to source, and the cost-per-call repair math stops making sense.
If your gas bill has trended up year-over-year on similar weather, the furnace is losing efficiency — heat exchanger fouling, blower wear, or a failing inducer.
Bedrooms cold while the basement bakes? That's almost always a sizing or distribution problem — and it gets worse as the equipment ages and air-flow falls off.
Furnace flames should be steady, sharp blue. Yellow or flickering flames mean incomplete combustion — and possible carbon monoxide. Call us immediately and ventilate the area.
