⚖️ Single-Stage, Two-Stage or Variable-Speed?
| Single-stage | Two-stage | Two-stage + variable-speed blower | |
|---|---|---|---|
| How it heats | Always full fire | Low fire most of the time, high fire on the coldest days | Two-stage burner plus a blower that ramps up and down smoothly |
| Comfort | Warm bursts, more temperature swings | Steadier, fewer cold spots | Most even temperature, quietest |
| Running cost | Highest electricity use | Lower | Lowest, especially with central AC or a heat pump |
| Best for | Tight budgets, small homes | Most homes | Comfort-focused homes, AC or heat pump pairing |
All the furnaces we sell are high-efficiency condensing models (96% to 97% AFUE), which means about 96 to 97 cents of every gas dollar becomes heat in your home. What is a high-efficiency furnace?
📏 What Size Furnace Do You Need?
| Furnace input | Typical home* |
|---|---|
| 40,000 BTU | Condos, small bungalows, very well insulated homes |
| 60,000 BTU | ~1,200–1,800 sq ft |
| 80,000 BTU | ~1,800–2,500 sq ft |
| 100,000 BTU | ~2,500–3,200 sq ft |
| 120,000 BTU | Large or older, draftier homes |
*Rough guide only. Many Toronto homes have an oversized furnace from decades ago. An oversized furnace short-cycles, wastes gas and wears out sooner, so we size from a heat-loss calculation. The blower size also has to match your AC or heat pump.

🔥 Add a Heat Pump to Your Furnace?
A furnace can be paired with a heat pump instead of a central AC. The heat pump cools in summer and heats on mild days, and the furnace takes over in deep cold. This hybrid (dual fuel) system can cut gas use, and eligible heat pumps may qualify for government heat pump rebates. If you are replacing your furnace and AC together, ask us to quote both options.
🔧 What Standard Installation Includes
- ✓ Removal of your old furnace
- ✓ New furnace connected to your existing ductwork, gas line and electrical
- ✓ PVC venting (standard length) and condensate drain
- ✓ Thermostat connection
- ✓ Gas pressure, combustion and safety checks by TSSA-certified gas technicians
- ✓ Startup, airflow setup and full commissioning
- ✓ 1-year labour warranty and warranty registration
Extra work such as a new vent route or chimney liner, a gas line upgrade, ductwork or plenum changes, a condensate pump or a new AC coil is quoted separately and listed in writing before work starts. An optional 10-year labour warranty is also available; ask us for details.
