Central air conditioners typically last 10–15 years in Ontario’s climate. Units past that age often lose efficiency, use phased-out refrigerants, and break down more often — making replacement a practical option, especially when paired with an aging furnace since the two systems share components.
Durham HVAC Connect helps Durham Region homeowners compare replacement options without pressure. Call us and we’ll connect you with a local HVAC professional who can recommend appropriately sized equipment and discuss costs with you.
Sizing a new air conditioner is a calculation, not a guess. The professional will weigh the home’s square footage, insulation, window area and orientation, ductwork, and occupancy before recommending a size. Modern systems also matter for efficiency: today’s variable-speed units ramp down instead of cycling on and off, which does a better job of removing humidity during humid Durham summers.
