A mini split cost calculator for Portland and Vancouver: answer a few questions about the rooms and the house and see our typical range, line by line. Nothing is sent unless you choose to.

## Describe the job

## How do we work out your range?

This calculator from [Firlands Portland Mini Splits](https://firlandsportlandminisplits.com/) picks one of our typical ranges from the number of heads and the kind of job. Pumps and a panel upgrade go on as lines of their own.

| Job | What it means | Typical range |
| --- | --- | --- |
| One head | Short line run, pad or low bracket, new circuit | $4,000 to $8,500 |
| One head, harder job | Lines that climb floors, or a high wall or roof mount | $8,500 to $12,000 and up |
| Two heads | One outdoor unit, two rooms | $6,500 to $12,000 |
| Three or four heads | One outdoor unit, usually | $9,000 to $18,000 and up |
| Five or more heads | Whole home, often two outdoor units | $15,000 to $30,000 and up |
| Concealed ducted unit | One air handler with short ducts | $8,500 to $16,000 and up |
| Each added head | Additional indoor head on a multi-zone system | $2,000 to $4,000 |
| ADU, addition or garage | One or two heads | $5,000 to $12,000 and up |
| Replacement, like for like | Same spot, lines pass the test | $4,000 to $8,000 and up |
| Replacement with more work | New lines, a new spot or several heads | $8,000 to $18,000 and up |
| Condensate pump | Per head that cannot drain downhill | $150 to $500 |
| Panel or service upgrade | 100 amps to 200 amps | $2,500 to $6,000 |

Nothing is scaled or stretched. Every number the calculator shows is one of these ranges, a whole number of them or a sum, so you can check each line against the table.

## Which answers move the price?

The number of heads matters most. After that, how far the lines travel and where the outdoor unit sits decide whether a one-room job stays in our standard range.

- **Heads and head type.** Each room with its own head adds equipment, lines and a drain. Ceiling cassettes and ducted units add framing and ceiling work.
- **Line run and outdoor unit.** Lines that climb floors, and a high bracket or roof mount, push the price up. A pad on the ground is simplest.
- **Drains.** A head that can't drain downhill to the outside needs a condensate pump.
- **The panel.** Most houses only need a new breaker. A full panel or an older 100-amp service may need an upgrade first.
- **Cold-climate equipment.** Heads that heat through a hard freeze cost more than cooling-first models.

The [Portland cost guide](https://firlandsportlandminisplits.com/guide/mini-split-installation-cost-portland/) explains each driver, and the [size calculator](https://firlandsportlandminisplits.com/tools/mini-split-size-calculator/) gives a planning size for each room.

## How do we set your actual price?

In a written estimate after the site visit. We measure each room, size each head from a load calculation, check the panel and walk the line routes and the outdoor spot.

The estimate lists each head and its capacity, the outdoor unit, the line route, the drains, the circuit, the permits, the price and what's excluded. The [installation process guide](https://firlandsportlandminisplits.com/guide/mini-split-installation-process/) walks through the day itself.

## What about permits and rebates?

Every install gets a mechanical permit, and most need an electrical one. In the City of Portland the fees for a typical single-zone install run $187 to $382, and we include them in our price.

| Program | Who it's for | Amount listed |
| --- | --- | --- |
| Energy Trust of Oregon | Detached house replacing electric resistance heat | $800 |
| Energy Trust of Oregon | Duplex to fourplex, townhome, rental or income-qualified | $1,800 |
| Clark Public Utilities | Vancouver or Clark County home with permanent electric heat | $900 |

Amounts and rules change, and gas-heated homes don't qualify for either ductless offer. The [Oregon rebates guide](https://firlandsportlandminisplits.com/guide/mini-split-rebates-oregon/) covers the paperwork, and the [Portland permit guide](https://firlandsportlandminisplits.com/guide/mini-split-permit-portland/) covers the inspections.

## Questions about the calculator

### Why does a long line run move a one-room job into a higher range?

Because the work around the head grows. Lines that climb a floor or cross the house take longer to route, need more cover outside and more refrigerant line, and a high bracket or roof stand adds a ladder or lift. That is why a one-head job with either uses our $8,500 to $12,000 and up range.

### Does the calculator take the Energy Trust incentive off the total?

No. It shows the amount beside the range, because it depends on the equipment, the heat it replaces and the program's rules on the day. For a detached house that replaces electric resistance heat, Energy Trust of Oregon currently lists $800, and we sign the application with you.

### Are Portland permit fees on top of the calculator range?

No. We include the permit fees in our price. In the City of Portland they run $187 to $382 for a typical single-zone install, and more for a multi-zone system or a service upgrade.

### What happens to my calculator answers when I send the form?
