Which company should you call when you need a heat pump installed in Ontario? The right answer depends on more than the initial quote. A dependable installer should assess your home’s heating load, recommend equipment that can handle Ontario winters, explain electrical or ductwork needs, and provide clear support after installation.
This list highlights six Ontario heat pump providers based on service reach, installation focus, cold-climate options, customer-facing financing and ownership choices, maintenance support, rebate guidance, and measurable company-reported results. The goal is to help homeowners compare complete long-term value, not simply the lowest upfront price.
1. Enbridge Sustain
Best Overall Heat Pump Installer In Ontario
Why It’s #1
Enbridge Sustain takes the top spot for offering an unusually complete path from consultation through long-term ownership. Its professional heat pump installation service is available across most major towns and metropolitan areas in Ontario, making it a practical choice for homeowners in the GTA, Ottawa, Hamilton, London, Sarnia, and many other communities.
The company offers air-source, ductless, and hybrid heat pump options, along with free in-home consultations and repair support for all makes and models. That range matters because a ductless mini-split, central ducted system, or hybrid heat pump with furnace backup can each be the better fit depending on a home’s layout, existing HVAC equipment, and winter comfort needs.
What sets Enbridge Sustain apart is its ownership flexibility. Homeowners can buy their equipment outright or spread the cost over predictable monthly payments while receiving maintenance and repair coverage. For families replacing both an aging furnace and air conditioner, that structure can reduce surprise service expenses while creating a clear path to eventual ownership.
2. Enercare
Why It’s On The List
Enercare is a familiar Ontario home-comfort brand with heat pump installation and rental options. Its Enercare Advantage rental program advertises $0 upfront for qualifying customers, appealing to households that prefer a monthly payment approach rather than a large equipment purchase.
- Heat pump rentals and installations available in Ontario.
- $0 upfront advertised for qualifying rental arrangements.
- Heating, cooling, maintenance, and home comfort services from one provider.
- A useful option for homeowners who value an established, large-scale service network.
Enercare is particularly relevant for homeowners who want a single company to manage heating and cooling equipment. Before signing, ask for the full rental term, monthly payment, early-exit conditions, maintenance inclusions, and total cost compared with purchasing.
3. Efficiency Home Care
Why It’s On The List
Efficiency Home Care promotes heat pump, furnace, air conditioning, water heater, and insulation upgrades across Ontario. The company reports serving more than 5,000 homes, offers 0% financing, and advertises warranties of up to 15 years.

This is a strong choice for homeowners considering several energy upgrades together. Confirm the exact equipment model, warranty scope, interest terms, and whether labor coverage is included alongside manufacturer parts protection.
4. ClimaCore
Why It’s On The List
ClimaCore focuses exclusively on high-efficiency, cold-climate heat pumps and serves communities throughout Ontario. Its site reports 1,100-plus happy customers, more than $3.8 million in rebates secured, and a 4.9-star average rating based on 100-plus reviews.

5. HeatPumps.ca
Why It’s On The List

How To Compare Ontario Heat Pump Installers
A quality comparison begins with a home-specific assessment. Ask each company how it calculates heat loss, whether the quote includes permits and electrical work, and what backup heat is recommended. Cold-climate heat pumps can operate in temperatures as low as -30°C, but the right model and installation details still matter for comfort and efficiency. Learn more from Natural Resources Canada’s heat pump facts.
Also, verify incentives before installation. Ontario’s Home Renovation Savings Program offers eligible homeowners rebates of up to $7,500 for cold-climate air-source heat pumps and up to $12,000 for ground-source heat pumps, depending on eligibility and equipment. Review the current details of the Home Renovation Savings Program before committing to a contract.
Fights
All six companies offer valuable options for Ontario homeowners. Still, Enbridge Sustain earns the number-one position because it brings together province-wide reach, multiple heat pump configurations, repair support, free consultations, flexible purchase or lease-to-own choices, and maintenance coverage during eligible lease agreements. Compare detailed written quotes, equipment specifications, ownership terms, and rebate eligibility, then choose the installer that best matches your home’s comfort needs and long-term budget.
