Mini split installation is one call away from a licensed local contractor. The call routes to a licensed pro in your area for an in-home zone assessment and a written quote — cooling and heating with no ductwork.
Wall or ceiling heads fed by a small outdoor unit — no ductwork to install.
A mini split is a heat pump, so each zone heats and cools on its own thermostat.
You get a price before any work — decided in your home, not over the phone.
One call routes to a licensed local contractor. You describe the rooms you want to condition.
The pro decides how many indoor heads you need and sizes the outdoor unit to match.
You get an itemised, fixed price before any work — heads, line sets, electrical, and warranty.
Mount the units, run line sets and condensate, dedicated electrical, EPA-608 charge, a full test, warranty registered.

Ductless wins in four situations: homes without ducts, additions and conversions the main system never reached, room-by-room zoning, and a room the central system never balances. Any one of these is where a mini split beats extending ductwork.
Older houses with radiators or baseboard heat can get central cooling without tearing in ductwork.
A garage, sunroom, attic, or bonus room that the main system never reached gets its own comfort.
Each indoor head has its own thermostat, so you condition the rooms you use and skip the ones you don't.
A hot upstairs bedroom or a cold home office the central system can't reach gets targeted spot comfort.
New to ductless? Start with what a mini split is, or price whole-home coverage on heat pump installation.
A proper ductless install is four jobs, not one: assessing and sizing the zones, mounting the indoor and outdoor units, running the line sets and condensate, then wiring dedicated electrical, charging and testing. Skipping the zone sizing or the condensate detail is where cheap installs fail.
| Step | What it is | Phase |
|---|---|---|
| Zone assessment & sizing | The contractor decides how many indoor heads you need and sizes the outdoor unit to match | 1Before the quote |
| Mount the units | Wall or ceiling indoor heads and the outdoor condenser, set and secured | 2Install day |
| Line sets & condensate | Refrigerant line sets and condensate drainage run between the indoor and outdoor units | 2Install day |
| Electrical, charge & test | Dedicated electrical, EPA-608 licensed refrigerant charge, an operation test, and warranty registration | 3Commissioning |
DIY mini-split kits exist, but a professional install protects the manufacturer's warranty and keeps the refrigerant and electrical work to code — refrigerant handling legally requires EPA-608 certification. A voided warranty or a condensate leak inside a wall costs far more than the labour it skipped.
There are a few ways to configure ductless — a single-zone head for one room, a multi-zone system for the whole home, a cold-climate model that heats hard in winter, or a ducted heat pump where the home already has good ductwork.
One outdoor condenser feeding one indoor head — the direct fix for a single room, an addition, or a spot that runs hot. The lower-cost path.
One condenser running two to five indoor heads, each with its own thermostat. The whole-home ductless setup, and what drives the price up.
A ductless mini-split is a heat pump, so it heats as well as cools. A cold-climate model keeps heating well below freezing.
See heat pump installation →If the home already has sound ductwork, a ducted heat pump may cover it more simply than many ductless heads.
See heat pump installation →Two decisions shape a ductless job: how many zones you need, which drives the price, and how each head is sized, which drives whether every room actually stays comfortable.
One outdoor condenser can run a single indoor head or a multi-zone system with two to five heads, each on its own thermostat. Zones are what move the number — more heads mean more indoor units, more line sets, and more labour. A single room is inexpensive; whole-home ductless is a multi-zone job.
An oversized head short-cycles and never dehumidifies; an undersized one runs flat out and still can't hold the room. A zone assessment sizes each head to its room, so the system is quiet, efficient, and comfortable — not just installed.
More zones cost more up front; correct sizing pays back every month in comfort and running cost.

Ductless installation runs roughly $2,500 to $15,000 or more on Carrier's 2026 figures, averaging near $3,000 for a simple single-zone system per Taskrabbit. The number of zones is what drives the figure — everything else adjusts around it.
A single-zone head in an easy-access room sits near the bottom of the range; a four- or five-zone whole-home system with ceiling cassettes and long line runs sits near the top. Carrier's 2026 guide spans $2,500 to $15,000 or more, and Taskrabbit averages a simple single-zone install near $3,000. Head type, line-set length, and electrical work move it within that band.
| What moves the number | Lower end | Higher end |
|---|---|---|
| Zones | Single-zone, one head | Multi-zone, four to five heads |
| Indoor head type | Wall-mounted head | Ceiling cassette or concealed-duct |
| Line set & access | Short run, easy access | Long runs, multi-story, hard access |
| Electrical | Existing capacity is adequate | New dedicated circuits or panel upgrade |
The itemised breakdown is on new system cost, and the only figure that counts is the written quote — actual prices come from the contractor after they see the house.
A single-zone install is often a one-day job; a multi-zone system can run two days. It runs in four stages: assess and protect, mount the units, run the line sets and condensate, then wire electrical, charge and test.
The crew confirms head placement, protects the walls and floors, and shuts off power.
Indoor heads are mounted and the outdoor condenser is set on a pad or bracket.
Refrigerant line sets and condensate drainage are run between indoor and outdoor units and sealed.
Dedicated electrical is connected, the system is charged to EPA rules, run through a full test, and the warranty registered.
Three things decided around install day quietly determine what the system is worth to you later: the manufacturer warranty (only valid if registered), the permit and electrical inspection, and any state, utility or manufacturer rebates — a ductless mini split is a heat pump, so it often qualifies.
Manufacturers cover parts for about ten years — but only with registration, and only on a professional install. A DIY kit usually voids it. Labour is a separate warranty from the contractor, often one to two years.
Most areas require a permit and an electrical inspection for the new dedicated circuit. The contractor pulls it. An unpermitted install can surface when you sell the home, so a quote that skips it is a red flag.
30% up to $2,000 heat-pump credit — expired Dec 31, 2025 (per ENERGY STAR / IRS). No longer applies.
State energy-office, utility, and manufacturer rebates still run for qualifying ductless heat pumps, and vary by ZIP code. A local contractor knows which programs are active in your area — worth asking before you pick the efficiency tier. Financing is widely available to spread the cost.
The price gap between two quotes usually hides in this checklist. A licensed installer does all six of the following; the low bid is low because it drops one or two of them.

Ductless mini split installation runs $2,500–$15,000 or more per Carrier's 2026 figures, averaging near $3,000 for a simple single-zone system per Taskrabbit. The number is driven mostly by the number of zones. The full breakdown is on our new-system cost page, and the exact figure is a quote from the contractor.
A zone is one indoor head with its own thermostat. One outdoor condenser can support a single zone or, on a multi-zone system, two to five indoor heads. More zones means more indoor units and line sets — and a higher install cost.
For a single room or a home without ducts, usually yes — there's no ductwork to install. For whole-home cooling across many rooms, a multi-zone mini split can approach or exceed a central system, so it comes down to your layout.
DIY kits exist, but professional installation protects the manufacturer's warranty and keeps the refrigerant and electrical work to code — refrigerant handling legally requires EPA-608 certification. For most homeowners a licensed install is the safer money.
Yes. A ductless mini split is a heat pump, so it both heats and cools. In cold climates, a cold-climate model keeps heating well below freezing — the same technology covered on our heat pump installation page.
