Heat Pump Installation & Repair in Toronto, ON
A heat pump heats and cools from one unit, and because it moves heat rather than burning fuel to make it, it delivers far more energy than it draws. Northfield Mechanical installs and repairs ducted and ductless systems across Toronto and the GTA, with Ontario rebates on qualifying installations and a 10 year warranty on manufacturer parts.

How a Heat Pump Works
A heat pump moves heat rather than generating it. In winter, it pulls heat out of the outdoor air, even when that air is cold, and carries it inside. In summer, it reverses and moves heat the other way, which is exactly what your air conditioner already does. One unit, both seasons, and no combustion in the house.
That transfer is why efficiency figures look unusual. A gas furnace can never exceed the energy it burns, while a heat pump delivers several times the energy it consumes in mild weather, because most of the heat is collected rather than created. That multiple falls as the outdoor temperature drops.
Do They Work in a Toronto Winter
Yes, and this is the question every GTA homeowner asks first. Cold climate heat pumps are rated to keep producing useful heat well below freezing, a long way past where older models gave up. Capacity does fall as the temperature drops, so many Toronto homes run a hybrid setup: the heat pump carries most of the season, and the gas furnace takes over on the coldest days. Which of the two is cheaper to run on a given day depends on the gas and electricity prices at the time, and a hybrid setup switches between them, which is also the least disruptive option since the existing furnace stays in place as backup.
Ducted or Ductless
- Ducted systems use the ductwork you already have, which suits most GTA homes with forced air heating and keeps the install straightforward.
- Ductless mini splits mount on the wall and serve one zone each, which suits additions, basements, garages, older homes with no ducts, and rooms that never sit at the same temperature as the rest of the house.
Installation and Rebates
Installation begins with a load calculation for the house rather than a guess, because an oversized heat pump short cycles and an undersized one never catches up. From there we select equipment, confirm the electrical service can carry it, set the outdoor unit, run the line set and charge the refrigerant to spec. We install Rheem, Goodman and Keeprite among the brands we carry.
Ontario homeowners can qualify for rebates on eligible heat pump installations. The amount depends on the program, the equipment and the home, and programs change, so ask when you book and we will tell you what is current rather than quoting a figure that has moved.
Heat Pump Repair
Common faults are refrigerant leaks, a failed reversing valve that leaves the system stuck in one mode, electrical and capacitor problems, and a defrost cycle that is not clearing the outdoor coil. A heat pump runs all year rather than half of it, so twice yearly maintenance matters more than it does on a furnace. We cover Toronto homes, Vaughan, ON, Richmond Hill, ON and the wider GTA seven days a week. Installations carry a 10 year warranty and repairs a two year warranty. Book a service visit.
