Short answer: A single-zone ductless mini-split usually costs about $3,500 to $7,000 installed in Ontario in 2026. Cold-climate models that also heat in winter run higher. Multi-zone systems with three indoor heads usually cost $9,000 to $22,000. A cold-climate heat pump on the Natural Resources Canada list can qualify for up to $7,500 back through Ontario’s Home Renovation Savings program.
Installed price ranges
| System | Published Ontario installed range (CAD) | What moves the price |
|---|---|---|
| Single zone, small (about 9,000 BTU) | $3,500 to $5,500 | Wall location, line set length, electrical run |
| Single zone, mid (about 12,000 BTU) | $3,800 to $7,000 | Efficiency, head type |
| Single zone, cold-climate (about 18,000 BTU) | $5,500 to $9,000 | Low-temperature heating rating |
| Three indoor heads (multi-zone) | $9,000 to $22,000 | Number and type of heads, line hides, panel capacity |
What changes the price in your home
- Number of indoor heads. Each room you want to heat or cool separately needs its own head. One outdoor unit can serve several heads.
- Cold-climate or cooling-focused. Cold-climate heat pumps keep heating at much lower outdoor temperatures and cost more. Many are rated to -25 °C or lower, depending on the model.
- Line set length and route. The copper lines run between the outdoor unit and each head. Longer runs and covers (line hides) add labour and material.
- Electrical work. Most systems need a dedicated circuit. An older panel may need work.
- Mounting. Wall bracket, ground pad or roof, and how hard the outdoor spot is to reach.
- Permits. Mechanical and electrical permits may apply, depending on the job.
The rebate that changes the math
Ontario’s Home Renovation Savings program offers up to $7,500 for a cold-climate air source heat pump. The amount is based on the size of the heat pump installed, and the unit must be on Natural Resources Canada’s qualified products list (Save on Energy, read October 26, 2026). A ductless cold-climate heat pump can qualify. A cooling-only unit cannot. Check the current amounts and your model before you sign. Our heat pump cost guide explains the rebate steps.
Ductless or central air?
If your home already has good ductwork, central air is usually cheaper and simpler. Ductless wins in a few cases:
- Homes without ducts.
- Additions and finished basements.
- A room that never holds temperature.
- When you want a heat pump that qualifies for the rebate.
Our ductless vs central air guide compares both side by side.

Usually one per room or open area you want to control separately. One outdoor unit can serve several heads, which is cheaper than separate systems.
