HVAC in Markham
Markham has grown into one of the GTA's biggest cities, and the housing reflects it — heritage homes in Unionville, established 1980s and 90s subdivisions, and newer master-planned communities like Cornell. Each generation of housing needs a different mechanical approach.
Unionville's heritage core
Older homes near Main Street Unionville often have mechanical systems retrofitted into spaces that predate central heating and cooling entirely.
1980s and 90s subdivisions
A huge share of Markham's housing dates to this era, with original furnaces and AC units frequently well past their efficient years by now.
Newer master-planned communities
Areas like Cornell come with modern, tighter mechanical closets and builder-installed equipment that's often still under warranty.
Dense townhouse blocks
Markham has a lot of townhouse developments, which means shared walls and tighter side-yard clearance for outdoor units.
1990s Markham Furnace Finally Showing Its Age
A huge portion of Markham's housing was built in the same 20-year stretch, which means a lot of original furnaces and AC units are hitting the same wall at roughly the same time — rising bills, more frequent repairs, less consistent comfort.
We Tell You Honestly Where the System Stands
