Heating & cooling in Newmarket, Ontario
Busy families want heating and cooling that just works. We explain what failed, what your options are, and what we’d do in our own place.
Newmarket’s mix of established streets and new infill means tight mechanical rooms and rebate-friendly heat-pump upgrades. We map paperwork before we order equipment.
Short cycling, uneven floors, and ‘my AC works but the house feels muggy’ are common calls — we start with airflow and charge discipline, not a premature box swap.
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 Newmarket
- 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, Ducted & Ductless — Cold-climate heat pumps and ductless systems sized, commissioned, and supported for Ontario winters.
- Water Treatment — Whole-home water filtration, water softeners, reverse osmosis systems (RO), drinking water filtration, and water treatment replacement and service. Authorized Excalibur Water Systems Dealer in Canada.
- Water Heaters & Tankless — Tankless, power vent, natural draft and heat pump water heater installation, replacement and service. Authorized Rinnai Dealer, also servicing Rheem and Bradford White systems.
- 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.
