Finding a Trusted HVAC Contractor in Markham
Markham's housing stock spans 1980s Unionville subdivisions, 1990s-2000s Cornell and Cathedraltown developments, and a fast-growing crop of high-density condo towers near Highway 7 and Warden. That mix means HVAC contractors here need range: swapping a 25-year-old furnace in a Berczy Village detached home is a different job than servicing a rooftop condenser stack for a Unionville condo corporation. Many of the 8 verified contractors on our list, including Maple Air and Climax Heating & Air Conditioning Central, specifically note condo HVAC experience, reflecting Markham's building profile.
Newer neighbourhoods like Cornell and Wismer were built to more recent Ontario Building Code energy standards, so homeowners there are often replacing original equipment for the first time and weighing heat pump options for efficiency rebates. Older sections near Thornhill and Milliken, by contrast, may still have ductwork or gas lines sized for equipment that predates current TSSA and ESA requirements, which can affect installation scope and pricing.
Whatever the vintage, any gas furnace or heat pump installation in Markham requires permits through the City of Markham's building division, and gas work must be performed by a TSSA-licensed contractor. Electrical connections tied to HVAC equipment should be ESA-inspected. Confirm licensing directly with any contractor before signing a contract.
Across the GTA, furnace installs typically run $3,800–$6,200, AC installs $3,500–$5,800, heat pumps $5,000–$12,000, and AC tune-ups $120–$250. Markham quotes tend to sit within these ranges, though condo and townhouse units with rooftop or split-system configurations may push toward the higher end due to access and ductwork complexity. Detached homes in older Thornhill or Milliken sections may see added cost if original ductwork or gas lines need upgrading to meet current code. Always request an itemized quote covering equipment, permits, and any electrical or gas line work.
Frequently Asked Questions
Do I need a permit to replace a furnace or install a heat pump in Markham?
Yes. The City of Markham's building division requires a permit for furnace replacements and new heat pump installations, and gas-fired equipment must be installed by a TSSA-licensed contractor. Ask your contractor to confirm they will pull the permit and arrange required inspections.
Are condo HVAC systems in Markham serviced differently than detached homes?
Many Markham condos, particularly around Unionville and Highway 7, use rooftop units, PTAC systems, or shared mechanical rooms rather than standalone furnaces. Contractors like Maple Air and Climax Heating & Air Conditioning Central list condo-specific HVAC service, since access rules, condo board approvals, and equipment types differ from a typical detached-home install.
Is a heat pump a good option for a Markham home?
Heat pumps work well in Markham's climate for both heating and cooling, and can reduce reliance on gas furnaces. Cost ranges from $5,000-$12,000 depending on home size and existing ductwork. Newer builds in areas like Cornell or Wismer, built to more recent energy codes, are often good candidates since ductwork and insulation are already sized appropriately.
