The Short Answer

$9,200 – $20,000

That is what most of our customers paid for a ductless system, fully installed, before rebates. The typical job is about $14,800. After utility rebates and Mayster discounts, most paid $8,000 – $18,000. The number of rooms is the biggest swing.

Good

Better

2–3 Zones

About $18,400

One outdoor unit running a few indoor heads, each with its own temperature. Most paid about $16,100 after rebates and discounts.

Best

Whole-Home, 4+ Zones

About $40,800

Heating and cooling for the whole house with no ductwork. High-heat models for our coldest nights.

What Pushes Your Price Up or Down

1

Number of Zones

Every room with its own head adds equipment and labor. This is the biggest driver.

2

Head Style

Wall-mounted heads cost the least. Ceiling cassettes and slim ducted units cost more but hide better.

3

Line Set Runs

Long runs, multiple floors and tricky routing add material and labor.

4

Standard vs High-Heat

High-heat models keep heating when it gets cold out. They cost more up front.

5

Electrical Work

Mini-splits need their own circuit. We are electricians too, so it is one crew and one bill.

6

Rebates & Financing

2 in 3 of our ductless customers got a utility rebate, about $2,200 on average. Plus our $1,000 Instant Install Voucher and special financing on approved credit.

Why Some Quotes Are Cheaper

Oversized or undersized heads, sloppy line set work on the outside of your house, or no permit. Always ask what is included.

Why Some Quotes Are Pricier

Big ad budgets, commission-heavy sales teams and add-ons you didn’t ask for. Higher price doesn’t always mean a better install.

Where We Land

We’re usually right in the middle. Not the cheapest bid, not the priciest. What you get for it: a Bryant Factory Authorized install, permits pulled, line sets run clean and tidy, and the electrical done by our own electricians. Every new install comes with our 10-year labor and materials warranty. Our customers rate us 4.9 on Google across 731 reviews, and they keep mentioning the same things: we show up on time, explain every option, and leave the house clean.

Common Questions

Usually, yes, if your home has no ductwork, runs on baseboard or wall heaters, or has rooms that never get comfortable. They are a great fit for additions, ADUs, garages, bonus rooms and older homes where adding ducts would be a big job. If your home already has good ductwork, a ducted heat pump may be the better value. We will tell you honestly which one makes sense.

Plan on one indoor head for each room or area you want to control on its own. An open living and kitchen area can often share one head, while bedrooms usually get their own. We size every room on the visit so you do not pay for heads you do not need.

Yes. High-heat models keep heating well below freezing, which covers our coldest Puget Sound nights. For whole-home setups we size the system for winter, not just summer. Some homeowners keep their existing baseboards as backup, and that is fine too.

Often, yes. 2 in 3 of our ductless customers got a utility rebate, about $2,200 on average. We check what you qualify for and help with the paperwork.

Every new install gets our 10-year labor and materials warranty, and Bryant covers the manufacturer parts for 10 years.
