Ductless mini-split installation in Seattle.

A ductless mini-split brings comfortable, efficient heating and cooling to the rooms that need it most, without the cost or disruption of adding ductwork. Whether you're conditioning a single room, a new addition, or your whole home, our in-house team will help you find the right system for your space and your budget.

What it is

What is a ductless mini-split?

A ductless mini-split delivers heating and cooling to specific rooms without traditional ductwork, using sleek indoor units mounted on a wall, ceiling, or floor and connected to an outdoor unit. The outdoor unit moves heat in or out, while the indoor unit sends conditioned air directly into the room through a small bundle of refrigerant lines and wiring routed through a roughly 3-inch opening in the wall. Because the air goes straight into the room, mini-splits avoid the energy losses that come with leaky ductwork. Most modern mini-splits are heat pumps, so a single system keeps you cool in summer and warm in winter.

Is it right for you

Why a mini-split might be right for your home.

Mini-splits are a popular choice across the Seattle area because they provide efficient heating through mild winters and welcome cooling during increasingly warm summers. They're often the best solution for homes without existing ductwork, room additions, detached ADUs, garages, basements, home offices, and multi-story homes with rooms that never quite reach the right temperature, or any time you want independent, room-by-room comfort. While these indoor units are visible on the wall, there are options to conceal them, and they deliver flexible, efficient heating and cooling throughout your home.

Configurations

Configurations and indoor unit options.

Every home is a little different, so we'll help you choose the configuration and indoor unit style that best fits your space, your comfort goals, and your budget.

01

Single-zone vs. multi-zone

A single-zone system connects one outdoor unit to one indoor unit, ideal for a single room, garage, or ADU. A multi-zone system connects one outdoor unit to several indoor units, each with its own temperature control, so you can comfortably condition multiple rooms without separate outdoor units.

02

High-wall mounted

The most common option, offering the lowest installation cost and highest efficiency. Mounted high on the wall, it's a great fit for bedrooms, living rooms, offices, and basements.

03

Floor-mounted

Resembles a radiator or baseboard and provides excellent heating performance. Ideal for rooms with low ceilings, large windows, or finished attics.

04

Ceiling cassette

Installs flush into the ceiling with a clean look and 360-degree airflow. It costs more to install and needs attic or ceiling access, making it a good fit for open-concept spaces, living rooms, and kitchens.

05

Concealed ducted

A slim air handler feeds one or more rooms through short duct runs with no visible indoor unit. It's the highest-cost option and requires some ductwork, which makes it popular for higher-end remodels.
