Split AC Installation Cost in Canada: Per-Room Prices and Extras
What a ductless mini-split costs per room, and the line sets, brackets, circuits and pumps that push an install above its base price.
A typical ductless mini-split install for three rooms costs $10,000 before GST/HST, with most quotes landing in the $7,800 – $13,000 range. A basic system starts at $5,150, and a premium multi-zone setup reaches $19,300. Our figures are based on three rooms, so the per-room price is roughly a third of the total, but the extras below can change that arithmetic quickly.
For the full breakdown, see our Ductless mini-split guide. This article focuses on what sits outside the headline number.
How we build the per-room price
We calculate each install as labour hours × local rates plus materials, then check the result against market prices and real quotes. Each room gets its own indoor head. The outdoor unit, the refrigerant line set, the wiring and the commissioning are shared across the system.
That is why per-room cost falls as you add rooms, and why a single-room install can cost well over a third of a three-room one. The outdoor unit and the electrical work are roughly fixed. If you only need one room cooled, expect a higher cost per room than the average above.
The extras that push the price up
Most quotes start from a standard install. These are the items that move it.
- Long line sets. The copper pipe between the outdoor and indoor units is usually priced for a short run. A longer run, or one that has to be hidden inside walls or a basement ceiling, adds copper, insulation, labour and sometimes extra refrigerant. Ask what length is included.
- Wall brackets or a pad. The outdoor unit needs a ground pad or a wall bracket. Brackets are needed where the ground is soft, snow-prone or uneven, or where the unit has to sit off the ground. Ask whether this is in the base price.
- A new circuit. Mini-splits need a dedicated circuit. If your panel has no spare capacity, you may need a sub-panel or a panel upgrade, which can cost more than the unit itself in an older home. This work needs a licensed electrician and usually a permit. In Ontario, permits and notifications are filed with the Electrical Safety Authority (ESA) by a licensed electrical contractor.
- Condensate pumps. Each indoor head drains water. If a gravity drain to the outside isn't possible, for example in a basement room, a small condensate pump is needed. It is a modest cost, but it is also a part that can fail, so ask about access for servicing.
- Wall cores and finishing. Passing pipe through brick, block or concrete takes longer than through a stud wall. Neat covers for exterior line sets (line-set covers) also cost extra.
- Removal or disposal. If you are replacing an old window unit or system, ask whether removal is included.
Which extras are worth paying for
Not every add-on is optional.
- Electrical work is not negotiable. A licensed electrician and a permit protect your insurance and resale. A quote that skips them is not a bargain.
- Line-set covers are cosmetic. They protect the pipe from sun and damage, but they are the easiest item to trim if you need to cut cost.
- A condensate pump is a decision about room position. If you can choose a head location on an exterior wall, you can often avoid the pump entirely.
Should the system also heat?
Most mini-splits sold today heat as well as cool. If you are comparing this with a whole-home option, our Heat pump installation guide shows the costs for a ducted air-source or dual-fuel system, which suits homes that already have ductwork. A mini-split suits homes without ducts, additions, or a few problem rooms.
In Ontario, the Home Renovation Savings programme offers up to $7,500 toward a cold-climate air-source heat pump for homes heated by electricity, oil, propane or wood, or up to $2,000 for gas-heated Enbridge customers. It requires pre-approval and a participating contractor, so check eligibility before you sign. Outside Ontario, we have no other grant figures to quote here, so check your provincial programmes.
Related costs to budget for
If a new circuit means opening up an older electrical system, you may want to look at the House rewiring guide before committing to a panel upgrade. If you are also replacing a gas furnace, our Furnace replacement guide helps you weigh a dual-fuel hybrid against a full switch.
Checking your quote
Line up quotes on the same basis: number of heads, line-set length included, electrical work and permit, pad or bracket, condensate handling, and disposal. A low quote often leaves out two or three of these. Our "is my quote fair" tool lets you compare a quote against our live figures, so you can see which line is out of step.
The short version
- Budget about a third of the three-room figure per room, more for a single room and slightly less as you add heads.
- Ask for the line-set length, the electrical scope and the bracket or pad in writing.
- Treat electrical work and permits as required, and trim cosmetic items first.
- All our figures are before GST/HST, which applies to renovation work.
