Local HVAC
Heating & cooling in Markham, Ontario
Our Markham office is growing — ask what we’re running locally for installs and service. Same crew standards, shorter drive time for many neighbourhoods.
The Markham office at 7711 Yonge St supports many GTA-adjacent neighbourhoods with the same install documentation and warranty process as Keswick.
Condo-adjacent townhomes, detached basements, and light commercial rooftops all flow through the same licensed dispatch — ask what we’re promoting locally when you call.
From Markham, our regular dispatch reaches Richmond Hill and Stouffville west and north, out to Vaughan and North Toronto/Scarborough, and east through Pickering, Ajax, Whitby, Oshawa, and Clarington — call and we'll confirm timing for your specific address.
Offices: Keswick (430 The Queensway S, Unit 27) and Markham (7711 Yonge St). Same phone line for booking and warranty support.
What we're usually called for in Markham
- Heating — Furnace and heater installation, high-efficiency changeouts, boilers and hydronics, combustion and venting checks, and winter repair when limits roll or the house will not hold setpoint. We document temperature rise, safety proving, gas pressure where applicable, and filter or static issues that cause nuisance trips — then quote repairs that match what we measured, not guesswork.
- Cooling — Central air installs and changeouts, ductless commissioning, seasonal tune-ups with coil, drain, and capacitor checks, and refrigerant work that starts with leak search and electrical verification — not a quick top-off. We commission for sensible cooling and humidity control on muggy Ontario days, and we flag R-22 end-of-life equipment when patch jobs stop making sense.
- Heat pumps & indoor air quality — Cold-climate heat pumps, ductless, humidifiers, filtration, and thermostats that actually talk to your equipment.
- Commercial & light commercial — Rooftops, tenant fit-ups, planned maintenance, and sheet metal when the catalog doesn’t fit.
- Boiler, radiant floor heating & snow melting — Boiler installation, repair, and hydronic system upgrades, radiant floor heating for basements and renovations, and heated driveways or walkways that melt snow automatically.
- Whole-home humidifiers — Furnace-mounted humidifier installation, repair, and maintenance so winter heating season doesn't mean dry skin, static shocks, and cracking hardwood.
- Ductless heat pumps — Single- and multi-zone ductless heat pump installation, repair, and maintenance for homes without ductwork — plus current Home Renovation Savings rebate eligibility.
