Heat pump installation in Toronto: is it right for your home?

A heat pump is worth a look when your air conditioner is due for replacement, you heat with oil, propane or electric baseboards, or some rooms never get comfortable. One system cools in summer and heats in winter, and cold-climate models keep heating well below minus 20.

  • Your air conditioner is over 12 years old
  • You heat with oil, propane or electric baseboards
  • You’re adding a basement suite or addition with no ducts
  • You want to burn less gas without giving up comfort

If your AC still has good years left, we’ll say so, and our AC repair service can keep it running until you’re ready.

Ducted heat pump or ductless mini-split?

A ducted heat pump replaces your central AC and uses your existing ductwork, so it suits most homes with a furnace. A ductless mini-split needs no ducts and suits additions, basement suites, third floors and homes heated by a boiler or baseboards. Some homes use both.

Indoor equipmentA coil on the furnace or an air handlerWall or ceiling heads in each zone
ZoningOne zone unless dampers are addedEach head controlled on its own

Ductless suits century homes in the Annex, Riverdale and Cabbagetown that heat with radiators. Your boiler handles the coldest days while the mini-split covers cooling and milder weather.

Cold-climate heat pump performance in Toronto winters

A cold-climate heat pump is built and rated to keep producing heat in Toronto’s coldest weather, into the minus 20s. Its output drops as the temperature falls, so the right model, sized for your home’s heat loss on a January night, decides how much of the winter it covers alone.

A heat pump moves heat instead of burning fuel, so it can deliver more heat than the electricity it uses. Cold-climate models use variable-speed inverter compressors that ramp up as it gets colder. In winter the outdoor unit runs a short defrost cycle now and then, and a little steam is normal.

Heat pump vs furnace, or a dual-fuel heat pump?

A gas furnace burns fuel to make heat, while a heat pump moves heat and also cools. A furnace delivers hotter air on the coldest nights, and a heat pump is often cheaper to run in milder weather. A dual-fuel heat pump system pairs the two.

Gas furnace and cold-climate heat pump compared
FeatureGas furnaceCold-climate heat pump
HeatingAt any outdoor temperatureInto the minus 20s, with less output as it gets colder
CoolingNo, needs a separate ACYes, it replaces your AC
Efficiency ratingAFUEHSPF2 for heating, SEER2 for cooling

In a dual-fuel setup, the thermostat switches to the furnace on the coldest days, when gas costs less to run. Whether dual fuel or all-electric suits you depends on your home, your panel and current gas and hydro rates, so we price both. Our furnace team services the furnace side too.

What happens during heat pump installation in Toronto?

Every heat pump installation in Toronto starts with a home visit and a heat-loss calculation, followed by a flat-rate quote, a rebate eligibility check and the install itself. We confirm a two-hour arrival window for each visit and text you when the technician is on the way.

  • We measure the house, check the ducts and panel, and calculate heat loss room by room.
  • You get a flat-rate price, with ducted, ductless or dual-fuel options side by side.
  • We confirm current rebate eligibility with you before you buy.
  • We install and commission the system, then show you how to run it.

We install heat pumps across the GTA too, including North York, Richmond Hill, Vaughan, Markham, Mississauga and Oakville.

Heat pump installation in Toronto: sizing, panels and placement

A heat pump sized only to match your old AC is often too small for winter heating. We calculate heat loss room by room so the system is sized for a January night, not a mild October day, then check whether your ducts can carry the airflow it needs.

Electrical panel and line sets

A heat pump needs its own circuit, and some older homes with smaller panels need an upgrade first, so we check before we quote. We pressure test and evacuate each new line set and route the condensate drain.

Outdoor unit placement and permits

The outdoor unit needs airflow, a spot above the snow line and room for service, which takes planning in tight Toronto side yards. We handle any required permit, and in condos and townhouses we go over building rules with you first.

Heat pump efficiency ratings: HSPF2, SEER2 and COP

HSPF2 measures a heat pump’s heating efficiency over a season, and SEER2 measures its cooling efficiency. Higher numbers mean lower running costs. COP, the heat delivered for each unit of electricity, shows how efficient a heat pump is at one outdoor temperature, which matters in a Toronto cold snap.

Heat pump ratings and what they tell you
RatingWhat it measuresWhat to look for
HSPF2Seasonal heating efficiencyHigher is better, and it matters most in Toronto
SEER2Seasonal cooling efficiencyHigher is better if you cool a lot
COPHeat per unit of electricity at a set temperatureAbove 1 beats electric baseboards

Heat pump rebates in Ontario

The Home Renovation Savings Program, from Save on Energy and Enbridge Gas, is the heat pump rebate program open in Ontario right now. It offers rebates on eligible heat pumps installed by a participating contractor, and amounts depend on the system, your home and your current heating fuel.

The Canada Greener Homes Grant and Loan, the Enbridge Home Efficiency Rebate and the Oil to Heat Pump Affordability program are closed. Programs change, so we confirm current eligibility with you before you buy and help with the paperwork.

Check the Home Renovation Savings Program (opens in a new tab) page for current rules and amounts.

What affects heat pump cost in Toronto?

The cost of heat pump installation in Toronto depends on the system type and size, how many indoor heads you need, and what your ductwork and electrical panel need. After the home visit, you get a flat-rate price for the full job before work starts.

What affects the cost of a heat pump
FactorWhy it matters
Ducted or ductlessDuctless systems are priced by the number of indoor heads.
Ducts and electricalUndersized ducts or a full panel may need work first.
Backup heatDual fuel with a furnace, or electric backup, changes the design.
RebatesEligible systems may qualify for the Home Renovation Savings Program.

The price you approve doesn’t change halfway through the job.

Heat pump repair: common problems and causes

We handle heat pump repair year-round on ducted systems and ductless mini-splits, including defrost faults, refrigerant leaks, reversing valves, sensors and controls. Our 313A-certified mechanics find the actual fault and give you a flat-rate price to approve before any repair starts.

Common heat pump problems, likely causes and typical fixes
ProblemLikely causeTypical fix
Cool air in heating modeStuck reversing valve or low refrigerantTest the valve, find and repair any leak
Heavy ice that won’t clearDefrost sensor or control faultReplace the sensor or control board
Water dripping from a ductless headClogged condensate lineClear and re-slope the drain

Repair or replace your heat pump?

Repair usually makes sense when a heat pump is well short of its typical 15-year life and the fault is a single part like a capacitor, sensor or fan motor. Replacement makes more sense when an older unit needs a compressor or a major refrigerant repair.

Repairing versus replacing a heat pump

We give you both prices side by side and tell you which we’d choose for our own home.

Emergency heat pump service and safety first steps

If your heat pump stops heating in winter, call us any time. No-heat emergencies are answered 24/7 and go to the front of the line. If your thermostat has an emergency or auxiliary heat setting, switch to it so the backup heat keeps the house warm while you wait.

  • Smell gas near a dual-fuel furnace: leave the house right away, don’t flip switches or use your phone inside, and call Enbridge Gas at 1-866-763-5427 from outside.
  • Carbon monoxide alarm: get everyone outside and call 911. Ontario requires these alarms in homes with fuel-burning appliances.
  • Outdoor unit buried in snow: turn it off before clearing it, and never chip ice off the coil.

Heat pump maintenance

A heat pump runs in both seasons, so it works more hours than an air conditioner and benefits from yearly service. A tune-up checks refrigerant pressures, cleans the coils and ductless filters, tests the defrost controls and clears the condensate drain, keeping the efficiency you paid for.

Our maintenance plan includes two tune-ups a year and priority booking, so your heat pump and any backup furnace are checked before each season. Between visits, keep snow and leaves clear of the outdoor unit.

Heat pump brands we service

We service and repair heat pumps from all major brands found in Toronto homes, including Mitsubishi, Daikin, Lennox, Carrier, Trane, Goodman, Rheem, York and Napoleon. When you’re adding or replacing one, we recommend a model based on your home’s heat loss and ductwork.

FAQ

Heat pumps questions

Do heat pumps work in Toronto winters?

Cold-climate heat pumps are built for it and keep producing heat into the minus 20s. How much of the winter one can cover alone depends on the model and your home, which is what our heat-loss calculation answers. Many Toronto homes keep a gas furnace as backup for the coldest days.

Are there rebates for heat pumps in Ontario?

Yes. The Home Renovation Savings Program, from Save on Energy and Enbridge Gas, offers rebates on eligible heat pumps installed by a participating contractor. Amounts depend on the system, your home and how you heat it now. Programs change, so we confirm current eligibility with you before you buy.

What’s the difference between ducted and ductless heat pumps?

A ducted heat pump uses your existing ductwork and replaces your central AC. A ductless mini-split needs no ducts. Its indoor heads mount in the rooms that need them, which suits additions, basement suites, third floors and homes heated by a boiler or baseboards.

Can I keep my furnace if I install a heat pump?

Yes. In a dual-fuel system the heat pump does most of the heating and all of the cooling, and the furnace takes over on the coldest days. If your furnace is in good shape, you keep it. If it’s near the end of its life, we can price replacing both together.

Will a heat pump lower my energy bills?

It depends on what it replaces and on current gas and hydro rates. Replacing oil, propane or electric baseboards usually saves the most, since a heat pump delivers more heat than the electricity it uses. Against natural gas the numbers are closer, so we price all-electric and dual-fuel options side by side.

How long does a heat pump last?

Most heat pumps last about 15 years. Because a heat pump heats and cools, it runs more hours than an air conditioner, so yearly maintenance matters. Keeping the outdoor unit clear of snow and leaves and cleaning ductless filters also helps it reach its full lifespan.

Do I need a bigger electrical panel for a heat pump?

Not always. A heat pump needs its own circuit, and many homes have room for one. Some older Toronto homes with smaller or full panels need an upgrade first. We check your panel during the home visit and tell you before we quote if any electrical work is needed.

How long does heat pump installation take?

It depends on the system. Replacing a central AC with a ducted heat pump is similar to an AC swap, while a ductless system with several indoor heads takes longer. We tell you how long your job will take when we quote.
