Your furnace works hardest in the worst conditions — the dead of a Canadian winter. A single cracked heat exchanger or failing flame sensor is all it takes to leave your family without heat. Our certified gas fitters perform a real 60-minute inspection, not a 20-minute look-over. We catch issues before they become $1,500 emergencies, and you get a signed health report every visit.

A well-maintained furnace lasts 20+ years. A neglected one fails in 12–14. Our annual plan at $169/year pays for itself the first time it prevents a breakdown.

Boilers are built to last — but only with proper care. Whether you have a hot water or steam system, our certified technicians service all makes and models. From pressure relief valves and expansion tanks to full boiler replacements, we handle it all cleanly and correctly.

We also handle new boiler installations with proper sizing, venting, and commissioning — so it runs right from day one.

Heat pumps are the most energy-efficient way to heat and cool your home. One system, year-round comfort, lower utility bills. Our refrigeration-certified techs handle installation, maintenance, and repair on all makes — including cold-climate models built for Canadian winters.

We properly size every system before install and commission it fully — so you're not paying for heat pump headaches down the road.

Radiant in-floor heating is the most comfortable heat you can put in a home — no vents, no noise, no cold spots. Warm floors, even temperature from ground up. Alderwood installs and services hydronic (water-based) radiant systems, properly zoned and balanced for your space.

Working in a freezing garage all winter isn't a lifestyle — it's a problem with a fix. We install gas-fired unit heaters and infrared heaters in garages, workshops, and commercial spaces across Ontario. Properly vented, properly sized, code-compliant every time.

Hydronic heating uses hot water circulated through pipes and radiators or in-floor tubing to deliver consistent, efficient heat. It's quieter and more comfortable than forced air, and ideal for larger homes or zoned configurations. We install, service, and balance hydronic systems across the GTA.

Book a pre-season heating inspection before the cold hits. We check every component of your system — burners, heat exchangers, gas connections, controls, and safety devices — so you're not left scrambling in January. Best booked August through October for maximum availability.

Furnace dies at midnight in January? We answer. Our emergency line is live around the clock for Ontario homeowners. We dispatch as quickly as possible and prioritize no-heat situations — because losing heat in a Canadian winter is never just an inconvenience.

A weak capacitor or dirty coil doesn't announce itself — it just fails at peak heat on the hottest day of the year. Our complete AC tune-up catches these issues before summer arrives. Refrigeration-certified techs, every time.

New AC installation includes proper load calculation, correct sizing, and full commissioning. No guesswork.

No ductwork? No problem. Ductless mini-splits are perfect for additions, garages, older homes, or any space that needs its own temperature zone. They're quiet, efficient, and heat AND cool — one system for year-round comfort.

Our refrigeration-certified techs install, service, and repair all major brands.

Don't wait until the first heat wave to find out your AC isn't ready. A pre-season tune-up catches weak capacitors, low refrigerant, and dirty coils before they cause a failure on the hottest day of the year. Best booked March through May — before the summer rush.

A smart thermostat can reduce your heating and cooling costs by up to 23%. We install and program standard smart thermostats ($299) and premium models like Ecobee and Nest ($449) — wired correctly to your system and set up so you can actually use it.

Sediment silently builds in the bottom of your tank, reducing efficiency and corroding from the inside out. Our annual flush and safety inspection catches anode rod deterioration, T&P valve issues, and gas component wear before they cause failure.

We also install new tank water heaters with full venting and commissioning — no rentals, no contracts, you own it.

Tankless units are the most efficient way to heat water — but they need annual descaling or their heat exchanger clogs and efficiency tanks. Our full service keeps yours running at peak output year after year. We also install new units with proper gas sizing and venting.
