Quick answer
A ductless mini-split is priced by the outdoor unit and the number of indoor heads. On this guide's current product figures, a single-head system starts around $6,500 to $7,500 before tax and rebates, with each additional head adding roughly $3,500 to $4,500 depending on the equipment and installation path.
The short version
- One-head systems carry most of the base cost.
- Additional heads commonly add several thousand dollars.
- Line length and access change labour.
- Cold-climate rating matters for primary heat.
Why one quote can be much higher
A four-head home is not a one-head system with three cheap accessories. Each indoor unit needs mounting, refrigerant and drain lines, electrical connections and commissioning. Long line runs, difficult access and wall repairs also add labour.
Rebate treatment
Ductless capacity can qualify under the heat pump rules, and the rebate calculation follows the eligible system capacity and current fuel. Confirm the selected model and tonnage during pre-approval rather than assuming every mini-split receives the maximum headline amount.
When ductless beats a ducted quote
Homes without ducts avoid the cost of building a duct system. A ductless design can also heat only the rooms that matter. The trade-off is visible indoor heads and room-by-room temperature behaviour.
What to do next
List the rooms that need their own temperature control.
Ask for each head and the outdoor unit as separate line items.
Confirm the cold-climate rating and eligible rebate capacity.
