HVAC in Ontario 2026: The Honest Comparison
After 50+ years of installing HVAC across the GTA, here is the current landscape.
Option 1: Replace Like-for-Like (Gas Furnace + Central AC)
Cost: $6,000-$14,000 installed
Best for: Homes with existing gas service, straightforward replacement
Modern variable-speed furnaces reach 96-98% AFUE. Very reliable, established service network.
AC recommendation: 18 SEER+ for Ontario climate.
Option 2: Cold-Climate Air Source Heat Pump (Full Electric)
Cost: $12,000-$22,000 installed
Government rebates: Up to $6,500 combined (Greener Homes + Enbridge)
Net cost after rebates: $5,500-$15,500
Extracts heat from outdoor air down to -25C. Heats AND cools - one system.
Pairing: Most Ontario installers include electric resistance backup for days below -20C.
Best for: Homes wanting to reduce gas consumption, owners seeking rebates, homes with good insulation.
Option 3: Hybrid Heat Pump System
Cost: $15,000-$25,000 installed
Heat pump handles 80-90% of heating loads. Gas furnace activates at extreme cold. Best of both worlds - efficiency in moderate temps, reliability at -25C.
Increasingly popular choice in Ontario 2026.
Ductwork Reality
New systems expose old ductwork issues. Pre-1980 GTA homes frequently have undersized or unbalanced ducts. Budget $2,000-$8,000 for ductwork improvements when replacing HVAC.
