Furnace Replacement in Windsor, ON
Replacing a furnace in the off-season, before it fails, gives you time to compare options, including adding a heat pump, without a cold house pushing the decision.
Request an HVAC technicianSigns it's time
Repairs every winter, rooms that never warm up, rust or soot in the cabinet, a yellow flame on older models and rising gas bills all point toward replacement, especially once a furnace is well into its second decade.
Sizing
A new furnace should be sized from a heat-loss calculation for your home, not by copying the old nameplate. An oversized furnace runs in short bursts, leaves temperature swings and wears out sooner.
High-efficiency models
Modern high-efficiency furnaces vent through plastic pipes out a side wall and drain condensate to a floor drain or pump. Ask how the old chimney will be handled once it no longer vents the furnace.
Pair it with a heat pump
Windsor's mild winters suit heat pumps. A furnace paired with a heat pump lets the heat pump handle mild days and the furnace take over when it's very cold; see heat pumps.
Air conditioning too
If your AC is also old, replacing both at once lets them be matched to the same blower and ducts.
Gas work
Gas furnace installation in Ontario must be done by a TSSA-registered contractor with certified gas technicians.
Rentals and contracts
Some homes have rented furnaces or water heaters. Check any rental or financing contract before replacing equipment.
Timing
Late spring and summer are the easiest times to schedule a replacement.

Old chimney
When a high-efficiency furnace stops using the chimney, a water heater left alone on it may not vent well. Ask how it will be handled.
