Trusted HVAC services in North York

AC repair here covers everything from a tired condenser behind a Don Mills split-level to two systems serving a new three-storey home in Willowdale. Our 313A-certified mechanics check capacitors, contactors, the condenser fan, refrigerant charge and the condensate drain, then give you a flat price before fixing anything.

In bungalows, the usual complaint is a bedroom at the far end that never cools down. In large custom homes, it’s an upper floor that can’t catch up on a humid July afternoon. Both are often airflow problems, so we measure before blaming the air conditioner.

Air conditioner installation in North York starts with matching the coil to the furnace blower and checking the line set and electrical supply. We quote a ducted heat pump as an option too. On an R-22 unit, a leak is usually the signal to replace rather than recharge, since that refrigerant is no longer produced.

A heat pump suits both of the area’s main housing types. In a bungalow, a cold-climate ducted heat pump can replace the air conditioner and carry most of the heating on the existing ducts. In a larger home, it pairs with a modulating furnace as a dual-fuel system, with the furnace covering the coldest days.

Ductless mini-splits fill the gaps: a basement apartment that needs its own thermostat, a sunroom, or a bedroom over the garage the main system can’t keep comfortable. Before quoting, we run a load calculation and check the electrical panel.

Ontario’s Home Renovation Savings Program, delivered by Save on Energy and Enbridge Gas, offers rebates on eligible heat pumps. What you qualify for depends on your home and the fuel you heat with today, so we check before you commit. See our Ontario heat pump rebates page and our heat pump installation page for details.

There are fewer radiator homes here than in older parts of Toronto, but boilers still heat some older houses in Bedford Park and feed in-floor radiant systems in a number of custom builds. We also repair and replace water heaters and install humidifiers, filtration and ventilation, each with a flat-rate price first.

Boilers and in-floor radiant heat

We service hydronic systems of every age, from cast iron radiators to radiant floors with mixing valves and several zones. Typical repairs include circulator pumps, zone valves, expansion tanks and ignition faults. A replacement condensing or combi boiler is sized to the home’s heat loss and usually connects to the existing piping.

Tankless and high-recovery water heaters

Custom homes with three or four bathrooms often outgrow a standard tank. A tankless unit or a larger high-recovery tank keeps up with back-to-back showers, and we check gas supply and venting before recommending tankless.

Humidity, filtration and ventilation

New airtight homes need fresh air, and many already have an HRV that hasn’t been serviced in years. We clean and balance HRVs and ERVs, add furnace humidifiers for dry winter air, and fit media filters that trap more dust and pollen.

Call any time: no-heat and no-cooling emergencies are answered 24/7 and booked ahead of routine work. While you wait, a few safe checks can solve simple problems, but a gas smell or a carbon monoxide alarm means leaving the house first.

• Thermostat: confirm it’s on heat or cool, set a few degrees past room temperature, and not blank from dead batteries.
• Power: check the breaker and the service switch near the furnace, which is easy to bump in a finished basement.
• Error codes: note the blinking light pattern on the control board and tell us when you call.
• Gas smell: get everyone out without using light switches or phones, and call Enbridge Gas at 1-866-763-5427 once you’re outside.
• Carbon monoxide alarm: leave the house and call 911 first, then call us once it’s safe.

Every Ontario home with a fuel-burning appliance needs working carbon monoxide alarms, and a home with bedrooms on more than one floor may need several. The Ontario carbon monoxide safety guide (opens in a new tab) explains where they go. After a gas or CO call, we find out why the appliance failed before it runs again.

Two very different kinds of house often share the same street in North York. Original 1950s and 60s bungalows, split-levels and backsplits sit beside large custom homes that replaced their neighbours, and each needs a different approach to heating and cooling.

Don Mills was built as one of Canada’s first planned communities, and its homes, like many in Bathurst Manor, Lawrence Manor, Downsview, Parkwoods and Victoria Village, went up with compact basements and modest ductwork. Many of those basements have since been finished, which hides the ducts, blocks returns and adds space the original system never planned for. Some now hold a basement apartment.

In Willowdale, York Mills, Hogg’s Hollow, Lansing and Armour Heights, rebuilds are taller, wider and more open, with two-storey foyers and walls of glass. One furnace and one air conditioner on a single thermostat struggle here, which is why we often recommend zoning, variable-speed equipment or a second system for the upper floor.

Because North York is part of the City of Toronto, permits for additions and basement apartments go through toronto.ca (opens in a new tab), and our Toronto service area page covers the century homes closer to downtown.

Most of the problems we fix here trace back to aging equipment and ducts in post-war homes, or to big new homes with more space than one system can condition evenly. These are the calls we get most often, and the usual cause of each.

• Cold finished basements: bungalow supply runs were sized for the main floor, so a finished basement often needs added runs, balancing or a ductless unit.
• Hot and cold floors in large homes: one thermostat on the main floor can’t sense the upper floor, which zoning or a second system fixes.
• Short cycling: an oversized replacement furnace heats a small bungalow too fast, shuts off, and starts again minutes later.
• Whistling registers: high static pressure from undersized ducts makes air noisy after a furnace upgrade.
• Ignitor and flame sensor faults: the furnace tries to start, then shuts down after a few seconds.
• Frozen AC coils: low airflow from a dirty filter, closed registers or a weak blower ices the coil on hot days.
• Stale air and window condensation in new builds: airtight homes need an HRV or ERV that is running and balanced.

Repair or replace comes down to age, the cost of the failed part and what the system will need next. Many furnaces and air conditioners installed in the early 2000s, in bungalows and early rebuilds alike, are now near the end of their typical lifespan. We price both side by side.

Planning a renovation? Replacing an aging furnace as part of the project lets us size it for the finished house rather than the old one.

The biggest factors are the equipment you choose, the size and layout of the home, and what the existing ducts, venting and electrical can support. A bungalow furnace swap and a two-system custom home are very different jobs, so we price each after seeing it.

Every one of our HVAC services in North York comes with the same promise: you hear the diagnostic fee before we book, you approve a flat-rate price after the diagnosis, and that price doesn’t change halfway through.

Good maintenance means a furnace tune-up each fall and an air conditioner or heat pump tune-up each spring. Those visits clean burners, flame sensors and coils, test the safety controls, check refrigerant and clear the condensate drain, which keeps equipment efficient and catches worn parts early.

Our maintenance plan books both tune-ups and gives you priority booking when something breaks. Homes with two furnaces or two air conditioners can have every system checked in one visit. Between tune-ups, keep basement registers open and the filter fresh.
