What We Do

From full furnace replacement to honest repair assessments — we tell you what your furnace actually needs, not just what generates the most revenue for us.

96% High-Efficiency Furnace

Vents through PVC — no chimney required. Roughly 20% less gas consumed vs an 80% unit. Pays back the price difference in 4–7 years for most GTA homes. Best long-term choice.

80% Standard Efficiency Furnace

Lower upfront cost. Uses conventional metal flue — a direct swap if your existing venting is in place. Good choice when selling soon or when PVC routing is impractical.

Furnace Repair & Diagnostic

We diagnose before recommending. If the repair makes more financial sense than replacing, we'll tell you. If the furnace is past its useful life, we'll tell you that too — honestly.

Warning Signs

Signs It's Time to Replace Your Furnace

A struggling furnace costs you money every month. Know when repair stops making sense.

  • Furnace is 15+ years old and has had 2+ repairs in the last 3 years
  • Cracked heat exchanger — a carbon monoxide risk that requires immediate replacement
  • Gas bills are noticeably higher year-over-year with no change in usage
  • Uneven heating — some rooms cold, others warm — despite clean filters and open vents
  • Repair quote exceeds 50% of the cost of a new furnace
  • Banging, rattling, or popping noises on startup — signs of mechanical failure

FAQ

Furnace Replacement Questions

Complete furnace replacement in the GTA typically runs $3,800–$8,500 including equipment and installation. The main variables are 80% vs 96% AFUE, brand, BTU capacity, and whether venting changes are needed. We provide a same-day written quote for most jobs.
For most GTA homeowners planning to stay 8+ years, yes. The price difference is typically $800–$1,500. With 6+ months of heating season in Ontario, the fuel savings usually cover that gap in 4–7 years. If you're selling in 2–3 years, the 80% unit makes more financial sense.
Key indicators: furnace is 15+ years old, repair cost exceeds 50% of a new unit, you're calling for repairs more than once a year, or there's a cracked heat exchanger. A cracked heat exchanger is a carbon monoxide risk — that means immediate replacement, no exceptions.
Most replacements take 4–6 hours and we aim to have your heat back on the same day. Unusual venting configurations or ductwork modifications may take longer — we'll tell you upfront when we quote the job.
Permit and inspection requirements depend on the project scope and municipality. Gas work must be performed by properly certified technicians through a TSSA-registered contractor. We confirm and arrange any approvals required for your job.
Sizing is done by CSA F280 heat-loss and heat-gain calculation — not by matching your old furnace. Most Toronto detached homes (1,500–2,500 sq ft) fall in the 60,000–100,000 BTU range. An oversized furnace short-cycles, wears out faster, and leaves rooms uncomfortable. We size every job properly before recommending equipment.
In most cases yes. We inspect your existing ductwork and note any leaks, restrictions, or sizing issues during the quote visit. If your ducts are undersized for a two-stage or variable-speed furnace, we'll tell you and quote any modifications separately. Most GTA homes have serviceable ductwork that works fine with a new furnace.
Yes — our main office is in Thornhill. We serve the entire GTA including Toronto, North York, Scarborough, Richmond Hill, Markham, Vaughan, Mississauga, Brampton, Etobicoke, Ajax, Pickering, Aurora, and Newmarket. Same-day service is available across most of these areas.
