Our Work in Seattle

Midea heat pump with an air handler, 3 ton (36,000 BTU)

The outdoor unit went on a new pad beside the house, the air handler into a closet inside, and a smart thermostat onto the wall. The air handler had to fit the closet the house already had. Over the past year Seattle has been among the cities we are called to most.

  • The outdoor unit on its pad, line set run along the siding.
  • The air handler in the closet, lines and drain connected.
  • The same closet from the doorway.
  • The thermostat, set up and explained before we left.
  • Multi-zone job: the branch boxes in the attic.
  • Multi-zone job: one of the five indoor heads.
  • Multi-zone job: an outdoor unit and its line set covers.

Another Seattle job: a Mitsubishi multi-zone mini-split

The Seattle multi-zone job: booked, installed, inspected

The homeowner had asked several companies to price a mini-split system and chose our quote. We agreed on June 10, 2025 for the install and arrived that day as planned.

The crew set the Mitsubishi outdoor units on wall brackets, ran the line sets up the wall under covers and mounted the indoor heads you see in the videos on this page.

Some time after the job the City sent its inspector. The inspection passed with no remarks, and the homeowner left a five-star Google review.

"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"

Common Questions

FAQ: HVAC in Seattle

Can a multi-zone mini-split keep each room at its own temperature?

Yes. Every indoor head has its own setting, which one central system cannot do. The Seattle multi-zone job on this page runs several heads from its Mitsubishi outdoor units.

Do I need a permit for a heat pump in Seattle?

Yes. We file it with SDCI before work starts. An SDCI inspector checks the finished system, and on jobs where lines run inside walls also before they are covered.

Will a heat pump be too loud for my neighbors?

Seattle allows a heat pump up to 45 decibels at the property line, so we choose the spot and the unit with that limit in mind. Ductless systems are reviewed only if a neighbor complains.

Can you replace an oil furnace with a heat pump?

Yes. A heat pump can take over from an oil furnace, often on the same ductwork. The assessment tells you whether your ducts can be reused.

My house has no ducts. What are my options?

A ductless mini-split. Each room gets its own indoor head, and the line set goes through the wall to one outdoor unit. A single zone starts at $4,600 installed.
