Short-cycling and hot/cold rooms
Usually a furnace that is one or two sizes too large. We re-calculate the load and recommend a properly sized two-stage or modulating model.

Furnace installation & repair
A furnace is the single largest mechanical investment in a Toronto home. Get the sizing wrong and you live with short-cycling, dry air, and uneven temperatures for fifteen years. AeroFusion sizes every replacement with a Manual J load calculation and a written explanation before any equipment is ordered.
What we deliver
The work, itemized.
Every furnace installation & repair job from AeroFusion includes the following — written into the quote, signed off on commissioning.
- Two-stage and modulating gas furnaces (Lennox, Carrier, Trane)
- High-efficiency 96-98% AFUE replacements with rebate support
- Heat-loss / Manual J load calculations — never oversized
- Same-day no-heat emergency repair, fully-stocked truck
What our customers usually call about.
Rising gas bills
A 1990s 80% AFUE furnace can use 25-30% more gas than a current 96-98% AFUE model. The Enbridge HER+ rebate often closes most of the gap on replacement cost.
Cracked heat exchanger / yellow flame
A safety emergency. We inspect every quote-stage furnace for combustion and CO levels before recommending repair or replacement.
How we do furnace installation & repair.
- 01
In-home heat-loss assessment
A senior technician measures the home and runs a Manual J — not a clipboard estimate. You receive three equipment options sized appropriately.
- 02
Old furnace decommissioning
TSSA-licensed gas shutoff, R600A safe disposal, and registered manifest. Heritage homes get extra care for asbestos-era insulation and original ductwork.
- 03
Single-day installation
Drop cloths, shoe covers, and floor protection from the truck to the utility room. Most replacements are commissioned and heating again the same day.
- 04
Commissioning + warranty registration
Combustion analyzer measurement printed and emailed. Manufacturer warranty registered in your name within 48 hours.
Pricing, plainly.
High-efficiency furnace installations in the GTA typically range with size, model, and venting complexity. We provide a written, itemized quote within 24 hours of the site visit — no diagnostic fee, no upsell scripts.
