What Is a Heat Pump?
A heat pump is an electric heating and cooling system that transfers heat instead of creating it. In winter it moves heat from the outdoor air into your home; in summer it reverses direction and moves heat outside. The same system can therefore provide both heating and air conditioning.
Read the Natural Resources Canada heat pump basics for the underlying technology.

Why Choose a Heat Pump in Ontario?
Ontario homeowners use heat pumps for efficient heating and cooling from one system. Because performance varies by model and outdoor temperature, the right comparison is the equipment’s published capacity and efficiency at the temperatures your home will experience—not only a headline minimum operating temperature.
When comparing equipment, review the ENERGY STAR air-source heat pump guidance and use the NEEP cold-climate product list to compare low-temperature specifications. Proper sizing, duct airflow, electrical capacity and controls determine how the selected system performs in a particular GTA home.
Save on Energy currently advertises a top incentive of $7,500 on eligible cold-climate air-source equipment, with the final amount tied to capacity. Not every model qualifies, so check the official program page before purchasing.

How a Heat Pump Is Installed
A reliable installation is a sequence of decisions and tests, not just an equipment swap. The assessment, selection, installation and commissioning stages should work together so the heat pump can deliver the intended comfort at local winter and summer conditions.
1
Assess the home
Measure the home’s heating and cooling demand, then review insulation, windows, air leakage, ducts, electrical capacity and the existing equipment.
2
Select the system
Match capacity and low-temperature performance to the home, then confirm indoor and outdoor equipment compatibility, controls and any backup heat.
3
Install and connect
Place the equipment, complete refrigerant, condensate, duct and electrical connections, and follow the manufacturer’s installation requirements.
4
Commission and hand over
Test heating, cooling, airflow, refrigerant setup, defrost and controls; record settings and show the homeowner how to operate and maintain the system.
For equipment selection, compare verified low-temperature performance with the NEEP cold-climate product list and review ENERGY STAR heat pump guidance.
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.

Ontario Heat Pump Rebates: What’s Available in 2026
Ontario’s current province-wide offer is the Home Renovation Savings program. Eligible air-source projects can receive up to seven thousand five hundred dollars; eligible ground-source work can receive up to twelve thousand dollars. Capacity affects the air-source amount, and the indoor-and-outdoor equipment combination must appear on the applicable qualified-product list.
The former federal grant is no longer open
Natural Resources Canada stopped accepting new Canada Greener Homes Grant applicants in February 2024. Pages that still present it as an available $5,000 offer are outdated. NRCan maintains an official notice for the ended program.
What to confirm before signing
Ask which exact model combination qualifies, how capacity affects the incentive, whether an assessment or pre-approval is required, what documents you must keep and who is responsible for each submission. Rules can change, so rely on current official terms instead of an old promotion or estimate.
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
The installed cost depends on the home’s heating and cooling load, system type, capacity, efficiency, ductwork, electrical work, controls, permits and installation conditions. Try the online calculator for an early range, then book an assessment for load calculations and a project-specific proposal.
They can be a strong fit when the equipment is properly sized and its low-temperature performance matches the home. The practical comparison should include current energy rates, the existing system, cooling needs, backup heat, comfort goals, installed cost and any rebate for which the equipment actually qualifies.
Square footage alone isn’t enough. A load calculation considers the building envelope, window area, air leakage, duct airflow and Mississauga’s design temperatures. You’ll also need the chosen model’s actual output in cold weather; nominal tonnage doesn’t show how much heating capacity remains when outdoor temperatures fall.
Many straightforward residential replacements can be completed in one or two days. Duct changes, electrical upgrades, new line routing, hybrid controls, permits or difficult access can add time. The written quote should explain the expected sequence and what could affect the schedule.
Check the Home Renovation Savings offer on Save on Energy. The maximum benefit currently shown for an eligible air-source system is $7,500, and installed capacity affects the amount. The former federal Greener Homes Grant stopped taking new applicants. Verify the exact indoor-and-outdoor model combination and application steps on the official Ontario page before signing a contract.
Some cold-climate models are designed to operate at −20°C and below, but operation and useful heating capacity are not the same thing. Check the model’s published capacity and efficiency at low temperatures, then size the system and backup strategy for the home rather than relying on a single minimum-temperature claim.
A furnace creates heat by burning fuel or using electric resistance. A heat pump uses electricity and a refrigerant cycle to transfer heat. It reverses in summer to provide cooling, while a furnace provides heating only.
A heat pump works in both heating and cooling seasons, so a spring and fall professional check is a practical schedule for many homes. Filter and homeowner-maintenance intervals depend on the equipment and household; follow the manufacturer’s instructions and address unusual noise, icing or comfort changes promptly.
Sound varies by model, operating speed, installation and placement. Compare the manufacturer’s published sound rating and discuss setbacks from bedrooms, neighbours and property lines. A solid base, correct clearances and proper commissioning also help prevent avoidable vibration and noise.
It can in some homes when the heat pump and electrical system are sized for the full heating load. Other homes are better suited to a hybrid system that uses a heat pump for most conditions and a furnace for backup. The decision should follow a home assessment and low-temperature capacity review.
