Why Choose a Heat Pump in Ontario?
Ontario homeowners are making the switch to heat pumps in record numbers. A modern heat pump delivers up to three times more heating energy than the electrical energy it consumes, heating your home in winter and cooling it in summer — all from one system.
With cold climate models like the Bosch IDS 2.0 rated to operate at -25°C and below, today’s heat pumps are purpose-built for Canadian winters. Plus, government rebates of up to $5,000 through the Canada Greener Homes Grant make the switch more affordable than ever.
As a Bosch Approved Dealer with 43 years of experience, Furnace King has helped thousands of GTA homeowners make the transition. Call us at (905) 564-5464 for a free in-home assessment.

Heat Pump Maintenance
A well-maintained heat pump lasts longer, runs more efficiently, and breaks down less often. We recommend scheduling professional maintenance twice a year — once in spring before cooling season and once in fall before heating season.
What our maintenance tune-up includes:
- Filter inspection and replacement — The #1 cause of reduced performance
- Indoor and outdoor coil cleaning — Dirty coils reduce heat transfer efficiency
- Refrigerant level check — Low refrigerant means higher energy bills
- Electrical connection inspection — Prevents intermittent failures and safety hazards
- Thermostat calibration — Ensures accurate temperature readings
- Defrost cycle testing — Prevents ice buildup in winter
- Condensate drain clearing — Prevents water damage and humidity issues
Regular maintenance also keeps your manufacturer warranty valid. For a complete checklist, see our heat pump maintenance checklist.

Canada Greener Homes Grant & Ontario Rebates
One of the biggest advantages of installing a heat pump in 2026 is the substantial government rebates available to Ontario homeowners.
Canada Greener Homes Grant — Up to $5,000
The federal program offers up to $5,000 for eligible heat pump installations. Register, complete the installation with a qualified contractor like Furnace King, and submit your pre- and post-retrofit EnerGuide evaluations to receive your grant.
Oil to Heat Pump Affordability Program — Up to $10,000
Homeowners currently heating with oil can access up to $10,000 to cover the transition from oil furnaces to electric heat pumps.
Enbridge Home Efficiency Rebate
For homes connected to Enbridge Gas, additional rebates are available for energy efficiency upgrades including heat pump installations. This can be stacked with the Greener Homes Grant for even greater savings.
We Handle the Paperwork
At Furnace King, we have helped hundreds of GTA homeowners navigate the rebate process — from scheduling EnerGuide audits to completing applications and following up on approvals.

Choosing the Right Heat Pump for Your Home
Air-Source vs. Ground-Source
Air-source heat pumps account for over 90% of residential installations in Ontario. They are more affordable, require no excavation, and modern cold climate models perform exceptionally well. This is what we install most often and recommend for the vast majority of GTA homes.
Ground-source (geothermal) heat pumps offer the highest efficiency but cost $20,000–$40,000+ due to ground loop installation. For most Mississauga homes, air-source is the practical choice.
Hybrid and Dual-Fuel Systems
If you already have a gas furnace in good condition, a hybrid system pairs a heat pump with your existing furnace. The heat pump handles heating down to around -10°C to -15°C, and the furnace kicks in during the coldest stretches. You get most of the energy savings while keeping a proven backup. Learn more in our hybrid heat pump systems guide.
Cold Climate Considerations
For a standalone heat pump in Ontario, cold climate performance is non-negotiable. Look for models rated to at least -25°C with inverter-driven compressors. Our cold climate heat pump guide covers the specific models and features to look for.
Sizing Matters
An oversized heat pump short-cycles and wastes energy. An undersized unit struggles on cold days. Proper sizing requires a Manual J load calculation — exactly what we do during our free assessment. Read our heat pump sizing guide for details.

Frequently Asked Questions About Heat Pumps
How much does a heat pump cost in Ontario?
A complete air-source heat pump installation typically costs $5,000–$12,000 CAD before rebates. Premium cold climate systems like the Bosch IDS 2.0 fall in the $8,000–$12,000 range. After government rebates of up to $5,000, the net cost is often comparable to replacing a furnace and AC separately.
Are heat pumps worth it in Ontario’s cold climate?
Absolutely. Modern cold climate heat pumps operate efficiently down to -25°C or colder. Most homeowners see a return through lower energy bills within 5–8 years — sooner if gas prices continue to rise.
What size heat pump do I need?
A typical 1,500–2,000 sq ft GTA home usually requires a 3- to 4-ton heat pump, but accurate sizing requires a Manual J load calculation. We perform this during our free in-home assessment.
How long does installation take?
Most residential installations are completed in 1–2 days. Straightforward replacements are often done in a single day.
Can I get a rebate for installing a heat pump?
Yes. The Canada Greener Homes Grant provides up to $5,000. Homeowners switching from oil may qualify for up to $10,000. Enbridge also offers additional rebates. Furnace King helps with all the paperwork.
Do heat pumps work in -20°C weather?
Yes. Cold climate heat pumps with inverter compressors maintain strong heating output at -20°C and are rated to -25°C or lower. The Bosch IDS 2.0 is specifically designed for this performance.
What is the difference between a heat pump and a furnace?
A furnace burns fuel to generate heat. A heat pump moves heat using a refrigerant cycle — far more energy-efficient. A heat pump also provides both heating and cooling from one system.
How often should a heat pump be serviced?
We recommend professional maintenance twice per year — spring and fall. Between visits, check and replace your air filter every 1–3 months.
Are heat pumps noisy?
Modern heat pumps operate between 55–65 dB — roughly the volume of a normal conversation. Premium models like the Bosch IDS 2.0 can be as quiet as 56 dB.
Can a heat pump replace my furnace entirely?
In many Ontario homes, yes. A properly sized cold climate heat pump can serve as the sole system. Alternatively, a hybrid/dual-fuel setup uses the heat pump most of the time with your gas furnace as backup during extreme cold.
