Cost Guide

Typical ranges by job, what moves the number, and the public costs inside it.

Last Updated: November 12, 2026

The short answer

Firlands' typical range for a single-zone mini split in Portland is $4,000 to $8,500. Two heads on one outdoor unit run $6,500 to $12,000, three or four heads $9,000 to $18,000 and up, and a whole house $15,000 to $30,000 and up. Your price comes from the visit and the written estimate.

Key takeaways

- Single-zone: $4,000 to $8,500; a complex single-zone $8,500 to $12,000 and up.
- Each added head on a multi-zone system adds about $2,000 to $4,000.
- City of Portland permits for a typical single-zone install come to $187 to $382.
- Energy Trust pays $800 to $1,800 when a ductless system replaces electric resistance heat.

## Typical ranges by job

These are [Firlands Portland Mini Splits](https://firlandsportlandminisplits.com/)’ typical ranges for Portland and Vancouver, installed: equipment, labor, the line set, the circuit and the city permits.

| Job | What it covers | Typical range |
| --- | --- | --- |
| Single-zone, standard | One wall head, short line run, pad or bracket, new circuit, permits | $4,000 to $8,500 |
| Single-zone, complex | Long or multi-story line run, high bracket or roof, condensate pump, line-hide, larger cold-climate unit | $8,500 to $12,000+ |
| Two heads, one outdoor unit | Multi-zone with straightforward routing | $6,500 to $12,000 |
| Three or four heads | Multi-zone, routing through more than one floor | $9,000 to $18,000+ |
| Whole house, five or more heads | Often two outdoor units, replacing the main heat | $15,000 to $30,000+ |
| Ducted mini split | A concealed air handler serving two or three rooms | $8,500 to $16,000+ |
| Each added head | On a new multi-zone install | $2,000 to $4,000 |
| ADU, addition or garage | One or two heads sized to the space | $5,000 to $12,000+ |
| Replacement, like for like | Old line set passes the pressure and vacuum test | $4,000 to $8,000+ |
| Replacement with more work | New line set, relocation, new circuit, or a multi-zone | $8,000 to $18,000+ |

A “+” means the range is open at the top. Compare [single and multi-zone](https://firlandsportlandminisplits.com/guide/single-zone-vs-multi-zone-mini-split/) before you choose. An unusually long route, roof access or panel work can take a job past the range.

## What moves the price

Two jobs with the same label can price thousands of dollars apart. These are the things we look at on the visit:

- **How many heads, and which kind.** A wall head is the least expensive. A ceiling cassette or a ducted air handler costs more to buy and to install, and almost always needs a pump.
- **The line-set route.** A head on an outside wall with the outdoor unit right below it is the shortest run. A head on an inside wall, a run up two floors, or a route through a closet chase adds hours and line-hide.
- **Drains.** Gravity drains are simple ([condensate drain guide](https://firlandsportlandminisplits.com/guide/mini-split-condensate-drain/)). A head on an inside wall needs a condensate pump with a float switch, typically $150 to $500 more.
- **The outdoor unit’s spot.** A pad on level ground is the simplest ([placement guide](https://firlandsportlandminisplits.com/guide/mini-split-placement/)). A wall bracket, a stand to lift it above ice, or a roof mount adds labor and hardware.
- **The panel.** Most installs need one new 240-volt circuit ([electrical requirements](https://firlandsportlandminisplits.com/guide/mini-split-electrical-requirements/)). A full 100-amp panel may need a service upgrade first, typically $2,500 to $6,000 as separate electrical work.
- **Cold-climate equipment.** Models that hold their heating output at low temperatures cost more, and they’re the ones we choose when the system has to heat through a Portland January.

## What’s inside a Portland mini split price

Some parts of the price have public figures behind them; others depend on your house.

| Part of the price | What sets it | Local figure |
| --- | --- | --- |
| Labor | Hours on site, which the route and the head count decide | HVAC mechanics in the Portland metro earn a mean wage about 12% above the U.S. mean for the trade (Bureau of Labor Statistics); electricians about 44% above |
| City of Portland permits | A mechanical permit for the heat pump, an electrical permit for the circuit, plus the state surcharge | $187 to $382 for a typical single-zone install (City of Portland fee schedules) |
| Equipment | Capacity, efficiency and cold-climate rating | Itemized on your estimate |
| Line set, line-hide and drain | Length, number of floors, pump or gravity | Measured at the visit |
| Wall and finish repair | Usually small: one three-inch hole per head | Scope to check at the visit |

A wage isn’t a billing rate. The price of a job also carries the contractor’s license and insurance, vehicles, tools, the permit time and the time to come back for inspections.

## Permit fees in Portland

A typical single-zone install in Portland pays about $380 in city permit fees, and we include them in the price.

| Permit | Fee for one- and two-family homes |
| --- | --- |
| Mechanical: one heat pump | $167 minimum fee |
| Electrical: first new circuit | $174 |
| State surcharge | 12% |
| Typical single-zone total | about $380 |

A straight replacement can often go on the city’s minor label program instead. Gresham, Oregon City, Lake Oswego, Vancouver and other cities set their own fees. [Mini split permits in Portland](https://firlandsportlandminisplits.com/guide/mini-split-permit-portland/) covers who needs what.

## Rebates and incentives

In Oregon the main incentive is Energy Trust’s, for replacing electric resistance heat; in Vancouver it’s Clark Public Utilities’.

| Program | Amount | Who qualifies |
| --- | --- | --- |
| Energy Trust of Oregon, ductless heat pump | $800 single-family; $1,800 rentals, attached homes and income-qualified | PGE or Pacific Power customers in Oregon, when the system replaces electric resistance heat in the main living space; apply within 60 days |
| Clark Public Utilities, ductless heat pump | $900 | Vancouver and Clark County homes with permanently installed electric resistance heat; Washington-licensed network contractor |
| City of Portland, Energy Friendly Homes | No-cost or low-cost upgrades | Income-qualified Portland households, through the program’s own contractors |
| Federal 25C tax credit | Ended | Applied to heat pumps placed in service through December 31, 2025 |

Oregon’s state heat pump programs open and close as their funding allows; we check what’s open for your address before you sign. Gas-heated homes don’t qualify for Energy Trust’s ductless offer, because it pays for replacing electric resistance heat.

## Typical budgets

These show how the ranges play out on three common Portland jobs.

### One attic bedroom in a Sellwood bungalow

A 12,000 BTU cold-climate head on the gable wall, 18 feet of line-hide to a wall bracket in a narrow side yard, a gravity drain, and a new circuit from the basement panel: **$7,240** with permits, one day on site.

### Four rooms upstairs in a Rose City Park two-story

Three 9,000 BTU heads and one 12,000 on a 36,000 BTU outdoor unit, line sets through a closet chase, two gravity drains and two pumps, one new circuit: **$15,850** with permits, three days on site.

### Baseboards out in a Powellhurst-Gilbert split-level

A 15,000 BTU head in the living space and two 9,000s in the bedrooms, the outdoor unit on a wall bracket: **$13,400** with permits, two days on site, with Energy Trust’s incentive to apply for afterward.

## What it costs to run

The other half of the cost is the electric bill, and it depends on what the heads replace.

Against baseboard heat, a heat pump lowers the cost of every unit of heat. Against gas it depends on your utility’s rate, which differs between PGE and Pacific Power. [The electric bill guide](https://firlandsportlandminisplits.com/guide/mini-split-electric-bill/) works through the numbers, and [how many mini splits do I need?](https://firlandsportlandminisplits.com/guide/how-many-mini-splits-do-i-need/) helps you count heads before you price them.

## Questions about this guide

### Is a mini split cheaper than central air in Portland?

For one to three rooms in a house without ducts, usually yes, because there's no ductwork to build. For a whole house that already has sound ducts to every room, a central heat pump can cost less overall. We'll tell you which fits your house.

### Why do two quotes for the same room differ so much?

Usually because they're for different jobs: a different head size, a longer or shorter line-set route, a pump or no pump, a bracket or a pad, permits included or not. Compare what each quote lists, item by item, not just the total.

### Do the ranges include the pad, the line-hide and the permits?

Yes. A standard install includes a pad or bracket, line-hide on the outside wall, a new circuit and the city permits. What changes the number is how much of each the house needs: a long line-hide run, a stand above ice or a roof mount is priced on the estimate.
