A ductless mini split installation heats and cools your home without any ductwork. A slim outdoor unit connects to one or more wall-mounted indoor units through a small 3-inch hole in the wall. For older Everett, Edmonds, and Mukilteo homes built before central HVAC was standard, it’s the fastest, cleanest path to whole-home comfort — most installs finish in one to two days.
If your home was built before the 1970s, there’s a good chance it was designed around a boiler, baseboard heaters, or a wall furnace — not ducts. Every August, we talk to homeowners who assume air conditioning means tearing open walls and ceilings to add ductwork. It doesn’t.
How a Mini-Split Works
A ductless system has two parts: a compact outdoor unit (the heat pump) and one or more indoor “heads” mounted high on the wall. A small line set — refrigerant lines, power, and condensate drain — connects them through one 3-inch opening per room. Because it’s a heat pump, the same system that cools your living room in August heats it in January.
Why Older PNW Homes Love Ductless
- ✔No demolition — keeps original plaster, trim, and ceilings intact
- ✔Zoned comfort — set the bedroom to 68° and the living room to 72°
- ✔No duct losses — leaky ducts can waste 20–30% of a central system’s energy
- ✔Whisper-quiet — indoor units run quieter than a refrigerator
- ✔Replaces expensive electric baseboard heat with 2–3× the efficiency
One Room or the Whole House?
🌱 Single-Zone
The Problem Room
Perfect for that one space that never behaves: the upstairs bedroom that bakes in August, the garage conversion, the bonus room over the garage, or a home office. One outdoor unit, one indoor head, often installed in a single day.
🍂 Multi-Zone
Whole-Home Comfort
One outdoor unit powers up to eight indoor heads across the house. Each room gets its own temperature control — and the system replaces both your old heaters and the window AC units rattling away every summer.
Why We Install Mitsubishi Electric
We specialize in Mitsubishi Electric ductless systems because they lead the category in cold-weather performance, efficiency ratings, and noise levels — and their warranty support is the strongest we’ve worked with. Whether it’s a single-zone for a hot upstairs or an eight-zone whole-home design, we size and install it ourselves. See our Mitsubishi ductless solutions →
⚠ Pacific Northwest Note
Snohomish PUD and Puget Sound Energy have offered rebates for converting from electric baseboard or wall heat to a ductless heat pump. Programs change annually — we’ll confirm current rebates as part of your estimate.
Frequently Asked Questions
Are the wall units ugly?
Today’s indoor units are slim, neutral-white, and sit high on the wall — most guests never notice them. For certain layouts, floor-console and ceiling-cassette styles are also available.
How disruptive is installation?
Minimal. There’s no ductwork to build, no drywall demolition, and no attic crawl. A single-zone install is often done in one day; whole-home multi-zone systems typically take two.
Will it actually heat my home in winter?
Yes. Mitsubishi Electric’s cold-climate models deliver full heating capacity well below freezing — more than enough for Snohomish County’s mild winters, and dramatically cheaper to run than baseboards.
