A ductless split system in Ontario typically costs between $3,000 and $6,500 for a single-zone installation, while multi-zone systems can range from $6,000 to $15,000 or more depending on equipment selection, home requirements, and installation complexity. The final price can vary based on factors such as electrical upgrades, heat pump efficiency ratings, indoor unit placement, and the number of zones needed to properly heat and cool your home. Galaxy Plumbing provides homeowners with a detailed in-home assessment and transparent cost breakdown so you can understand your options, expected investment, and recommended system before moving forward with installation.
A single-zone ductless split installation costs $3,000 to $6,500 all-in for most Ontario homes, covering the outdoor compressor, one indoor air handler, the refrigerant line set, and a standard electrical hookup. Cold-climate models rated for Ontario winters carry higher SEER and HSPF efficiency ratings than standard equipment and price toward the higher end of this range. Wall-mounted indoor units are the most common configuration and cost less to install than ceiling cassette or floor-mounted styles.
This range assumes the home already has spare capacity on the electrical panel for a new dedicated circuit. Homes with an older 100-amp panel running close to capacity may need an upgrade before installation can proceed, which adds to the total project cost and is covered in more detail below. For a broader look at what professional HVAC and plumbing work costs across the GTA, see our breakdown of professional service costs in Ontario.
A two-zone ductless split system costs $6,000 to $10,000 installed, connecting one outdoor compressor to two indoor air handlers that each serve a different room. Three and four-zone systems typically range from $9,000 to $15,000 or more, with the final number set by unit capacity, the length of refrigerant line runs, and how many rooms need independent temperature control. Each additional zone adds both equipment cost and labour, since every indoor unit needs its own mounting, wiring, and commissioning.
Multi-zone systems make the most sense for homes replacing a failing central system, homes with rooms that run hot or cold independently of the rest of the house, or additions and basements that need separate climate control from the main floor. Mississauga homes with finished basements are a common example, where a two-zone system conditions the basement and one problem room on the main floor from a single outdoor unit. Our HVAC services page covers the full range of heating and cooling solutions available across the GTA.
Several variables move a ductless split quote up or down beyond the number of zones. The table below outlines what each factor typically adds to the final price.
Yes, a panel upgrade adds $2,000 to $4,000 to a ductless split project when the existing panel cannot support a new dedicated circuit. Every ductless installation requires its own circuit run from the panel to the outdoor compressor, and an older 100-amp panel already near capacity often needs to move to 200-amp service before that circuit can be added.
Galaxy Plumbing checks panel capacity during the initial home assessment and completes any required upgrade through a licensed electrician following Electrical Safety Authority permit requirements, so the electrical work and the ductless installation are covered under one written quote.
Yes, ductless split heat pumps qualify for Ontario's Home Renovation Savings Program at the same per-ton rate as central air-source heat pumps. The rebate amount depends on the home's current primary heating source, with electric, oil, and propane-heated homes eligible for larger incentives than gas-heated homes. Program terms and amounts can change, so homeowners should confirm current eligibility before signing a contract.
For GTA homeowners, a licensed contractor typically confirms rebate eligibility and rated heating capacity during the same visit used to quote the installation, since the rebate is calculated from the equipment's rated output at low outdoor temperatures rather than a flat dollar amount per system. Our overview of Ontario rebates for home heating and cooling systems provides useful context on how provincial incentive programs are structured.
In most homes, yes, because ductless systems avoid the duct losses that account for 20 to 30 percent of energy consumption in a typical forced-air system, according to Natural Resources Canada's guide to heating and cooling with a heat pump. Zone-level control also means only occupied rooms draw power, rather than conditioning an entire home to reach one temperature. Converting an unducted home to central air also carries a higher upfront cost than a ductless retrofit, since new ductwork through finished walls and ceilings adds significant labour.

Ductless split installation is one of the HVAC services Galaxy Plumbing provides across the GTA, alongside heat pump and furnace installation. Every quote follows the same four-step process.
The most reliable way to know what a ductless split will cost is a written quote based on an in-home assessment rather than a phone estimate. The prices in this guide reflect typical 2026 installed costs across the GTA, but electrical panel condition, zone count, and equipment tier are specific to each home and change the final number. Homeowners in Oakville, Mississauga, Toronto, Etobicoke, and Scarborough can request an assessment before deciding between a single-zone and multi-zone system.
The Galaxy Plumbing team assesses electrical capacity, zone requirements, and rebate eligibility on site before providing a written quote, so homeowners know the full cost before any work begins on their Ontario ductless split installation.
A single-zone ductless split costs $3,000 to $6,500 installed in most Ontario homes, covering the outdoor compressor, one indoor air handler, and standard electrical work. Cold-climate models built for Ontario winters price toward the higher end of that range. The exact cost depends on the electrical panel's spare capacity and the length of the refrigerant line run. For broader context on installation costs across GTA home services, see our guide to professional service costs.
A two-zone system runs $6,000 to $10,000 installed, while three and four-zone systems range from $9,000 to $15,000 or more. Each additional indoor unit adds equipment and labor cost since every zone needs its own mounting and wiring. Unit capacity and refrigerant line length also affect the final price. Our HVAC services page has full detail on multi-zone configurations available across the GTA.
Yes, ductless split heat pumps qualify for Ontario's Home Renovation Savings Program at the same per-ton rate as central air-source heat pumps. The rebate amount depends on the home's current heating fuel, with electric, oil, and propane homes eligible for larger amounts than gas-heated homes. For a broader look at how Ontario rebate programs work across heating upgrades, see our guide to Ontario heat pump and sump pump rebates. Program terms can change, so eligibility should be confirmed before signing a contract.
Every ductless split needs a dedicated circuit from the panel to the outdoor compressor, and an older 100-amp panel running near capacity often cannot support that new circuit safely. Upgrading to 200-amp service typically adds $2,000 to $4,000 to the project. Book a no-obligation estimate to include a panel assessment before installation begins.
In most homes, yes, because ductless systems avoid the duct losses that account for 20 to 30 percent of energy use in a typical forced-air system. Zone-level control also means only occupied rooms draw power, rather than conditioning the whole house to one setting. Actual savings depend on how many zones are used and how the home is occupied.

A single-zone installation typically takes three to five hours from mounting the indoor unit to final commissioning. Multi-zone systems with two to four indoor units usually take one full day, and larger installations can extend to two days. Any required electrical panel upgrade is scheduled separately before the ductless installation begins.
