Ductless shines in our damp, mild-to-chilly Puget Sound climate. In summer, inverter compressors sip power and keep bedrooms cool. In winter, modern cold-climate mini split models provide steady heat without space heaters or window units.
If you want efficient heating and cooling without tearing up your walls, a ductless mini split system is the fastest, cleanest upgrade you can make in Bellevue, WA. We size and install units for specific rooms, delivering quiet comfort and lower utility bills. Our team serves Bellevue and nearby King County neighborhoods — from Lake Hills ramblers to new builds in Somerset — with tidy, code-compliant work and clear written quotes.
Compared with ducted systems, mini splits avoid attic/garage losses and let you control comfort room by room—ideal for additions, daylight basements, bonus rooms, and ADUs. We color-match exterior line-set covers, seal all penetrations against rain, and keep outdoor components out of sight where possible.
Single-zone: primary suite, nursery, home office, garage conversion, over-garage studio, loft.
Multi-zone (2–6 indoor heads): one outdoor condenser serving several rooms, each with its own thermostat.
During your assessment we map room sizes, window exposure, insulation, and wiring to recommend the correct BTU and the least-visible line-set routes.
We coordinate permits with the City of Bellevue, follow WSEC requirements, and perform all code-required electrical with a licensed technician.
Mounting and weatherproof flashing; neat core drilling with dust collection
Insulated line-sets and tidy condensate routing (gravity or compact pump)
Deep vacuum and pressure testing for leak-free reliability
Dedicated electrical circuit and outdoor disconnect per code
Low-profile, color-matched line-set covers; fully sealed penetrations
Startup verification, controls setup, homeowner walk-through, complete cleanup
Most single-zone installations finish in one day; multi-zone systems typically take 1–2 days, depending on routing and electrical distance.
Pricing, Permits & Scheduling
Final pricing depends on capacity (BTU), line-set length, electrical distance, height/access, and finish details. After a short assessment you’ll receive a written quote with configuration options (single- vs multi-zone). We handle permits and inspection coordination and can review available utility rebates and financing on request.
We install Mitsubishi, Daikin, and Gree and match equipment to your priorities:
Controls: Wi-Fi/app control for schedules, geofencing, and remote access
Efficiency: high SEER2 ratings for reduced operating costs
Formats: wall-mounted, floor-mounted, and ceiling cassette options for open-plan spaces
Indoor unit types: wall-mounted (compact), floor-mounted (low placement), four-way ceiling cassette for even airflow in great rooms
Noise: select models reach ~20–24 dB(A) at low fan speeds—ideal for sleeping areas
Controls: Wi-Fi modules, app scheduling, parental locks, and remote monitoring
Filtration: washable multi-stage filters for dust, pollen, and odors (model-dependent)
Aesthetics: color-matched line-set covers, concealed routing where feasible, tidy penetrations with flashing/sealant
Most single-zone projects finish in one day. Multi-zone typically takes 1–2 days depending on routing and electrical distance.
We calculate BTU based on room area, windows, insulation, and sun exposure. Proper sizing prevents noise, short cycling, and inefficiency.
Yes. Multi-zone condensers commonly support 2–6 indoor heads, each with its own thermostat.
Yes. We take care of City of Bellevue permits and all code-required electrical
If your unit is older than 12–15 years and breaks down frequently, we’ll help you compare your options — no pressure.
