How to choose a home furnace
A calm checklist for Ontario homeowners comparing efficiency, sizing, and comfort features — before you request a quote.

Match the furnace to the house
Start with how the home loses heat: insulation, windows, air sealing, and duct condition. Square footage alone is a weak sizing shortcut.
Ask for a professional assessment (often a heat-loss calculation or equivalent). The goal is steady comfort without excessive short cycling.
Efficiency and features worth understanding
AFUE describes furnace fuel efficiency under standard test conditions. Higher AFUE can reduce fuel use, but installed cost and real savings depend on your current system and usage.
Discuss single-stage vs multi-stage or modulating operation, blower type, noise expectations, and thermostat compatibility.
A practical next step
List must-haves (budget range conversation, quiet operation, filter access), then request a quote with Comfort HVAC. Final installed pricing is confirmed after site review.
