Furnace Replacement in Lethbridge, AB
A furnace that needs frequent repairs, struggles in the wind or is approaching twenty years old is worth planning to replace before it fails in January.
Request an HVAC technicianSigns it's time
Frequent repairs, rooms that never warm up, rising gas bills, yellow burner flames, rust inside the cabinet or a furnace well into its second decade. Any one of these is a reason to get an assessment.
Sizing matters
A furnace that's too large heats in short bursts and wastes energy; one that's too small runs nonstop. A proper load calculation looks at the house's size, insulation, windows and air leakage, not just the old furnace's label.
High-efficiency models
Modern high-efficiency furnaces vent through plastic pipes out a side wall and drain condensate. Moving from an older mid-efficiency unit may mean new venting, a drain and changes to the old chimney liner.
Consider a heat pump too
Many Lethbridge homeowners pair a new furnace with a heat pump, which handles cooling in summer and much of the heating in milder weather. See heat pumps.
Permits
Replacing a gas furnace needs a qualified gasfitter and a gas permit under Alberta's Safety Codes Act. A good contractor arranges it as part of the job.

Plan ahead

Old equipment
Ask whether the quote includes removing the old furnace, and what happens to an old chimney that no longer vents anything.
