Heating & cooling in Keswick, Ontario
We’re up and down The Queensway regularly — from older lake homes with quirky duct runs to newer builds that need proper commissioning, not a rushed startup.
Our Keswick shop at 430 The Queensway S is where many installs and service trucks roll from — so Georgina and Simcoe calls often get realistic same-week scheduling when capacity allows.
We see a lot of lake-season humidity and winter wind off the water: oversized AC that short-cycles, marginal ductwork on additions, and furnaces that never got a proper post-install temperature-rise check. We fix the system, not just the symptom.
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 Keswick
- 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.
