Mini-Split Installation Cost in Seattle & Tacoma, WA

Base Price

2 zones, new installation	$8,100

Wall bracket or pad for the outdoor unit	+$150

Ductless systems are priced by the number of zones rather than by the square footage of the home, so no home size adjustment applies here. Air handling upgrades such as a filter cabinet, a UV scrubber or humidity control belong to ducted systems and are not offered on a ductless install.

What Customers Say About The Quote

"Professionalism at its best! Vlad and his assistant showed up when they were scheduled, installed everything on the quote (with no "onsite" extras that alot of contractors have) worked hard to impact the least amount of wall damage to run the lines and then cleaned up after themselves. As this installation was inside a working office, it was a pleasant surprise that they worked around my employees schedules, limited noise and you could hardly tell that they had to cut thru the walls it was soooo clean. In the end we went over the work, they made sure I was satisfied with the craftsmanship and then took the time to make sure I actually understood how all the equipment worked including helping me download the correct app to run everything. This happy customer will most certainly be using your company again for all my AC needs and have already recommended them to others--thanks again Vlad!!!"

"I needed to install a mini split system and I contacted several companies to estimate the cost of installation. These guys gave the best offer. Having agreed on the installation for June 10, the guys arrived on time and did everything qualitatively. After the work was completed, after some time I was assigned an inspection to check and everything went very well. The inspector had no complaints. Only positive impressions. Thank you. I highly recommend"

"They are fantastic! Very professional, knowledgeable, and so courteous. I had another company out that wanted to gouge me for a much higher amount for unnecessary work. Everheat did an amazing job at an affordable price, and I have a beautiful new furnace!! -Janyl Tremblay"

"We had the Everheat team come to replace the outdoor unit of our heat pump. They also serviced our indoor and outdoor units. Both times they provided excellent service at a good price in a timely way, would highly recommend them!"

"The team responded to my request and submitted the bid the same day, which was very reasonable. They showed up on time on the day of installation, and did an excellent job. Cleaned up, and showed me how to use the system. Would highly recommend"

Common Questions

Questions About The Price

Why does a new installation cost more than a replacement?

From two zones up, new line sets have to be run through the house. Two zones are $6,100 as a replacement and $8,100 as a new installation, three zones $7,600 and $11,100. At one zone the price is the same either way.

What does a ceiling cassette add?

$700 per zone instead of a wall unit. Five cassettes on a five zone system add $3,500.

Does the size of my home change a ductless price?

No. Ductless is priced by the number of zones, so no home size adjustment applies. Zones are what we work out at the free assessment.

Is the estimate free?

Yes. The in-home assessment is free and there is no obligation to book the work afterwards.

Does the price include permits?

Yes. City permits and the paperwork are pulled in your name and are part of the job, not an extra line.

Can the price change once the work starts?

You receive an itemized quote before anything begins, and customers specifically note that there were no onsite extras added later.

What payment methods do you accept?

Check, cash, Zelle, and online payment, whichever is easiest for you.

Do you offer rebates or financing?

We do not currently offer manufacturer or utility rebates ourselves, but we are happy to talk through what is available and how it fits your budget and timeline.

Ductless Mini-Split Installation Cost in Seattle and Tacoma

Ductless mini-splits are priced by zone rather than by tonnage, because each zone is a separate indoor head with its own line set. One zone installed is $4,600, two are $6,100 as a replacement or $8,100 as a new installation, and a five zone system runs from $10,600 when it replaces an existing setup to $14,100 as a new installation.

That gap between replacement and new installation appears from two zones up, and it is real work: new line sets have to be routed through the house. Ceiling cassettes instead of wall units are $700 per zone, 220V electrical work on a new install is $1,400, and a bracket or pad for the outdoor unit is $150. Because the system is ductless, there is no home size adjustment and no ducted air handling upgrades.

The instant estimate lets you set the zone count yourself, and the free in-home assessment settles how many zones the house actually needs and where a ceiling cassette suits a room better than a wall unit.
