Mini-Split Installation in Bellevue, WA
Zoned, whisper-quiet comfort without ductwork. Perfect for additions, ADUs, and rooms that never quite reach the right temperature.
Bellevue's downtown condo towers and the additions and ADUs going up in Somerset and Lake Hills are both classic mini-split territory — no ductwork to fight, just a compact system sized to the room or unit.
Symptoms we see every week in Bellevue
- One room that's always too hot or too cold
- Adding an ADU, addition, or converted garage
- Ductwork is impractical or too costly
- You want per-room temperature control

Mini-Split Installation in Bellevue: what's different here
Ranch and split-level homes in Lake Hills and Crossroads from the 1960s and 1970s often still have their first duct layout, and the hillside homes in Somerset run long duct and line-set paths between floors. Ductless mini-splits are a good fit for older Bellevue homes in Somerset and Lake Hills that have baseboard heat or no ductwork upstairs. We plan line-set routes to keep them neat on the outside of the house.
Permits and inspections
A mini-split install typically needs a mechanical permit plus an electrical permit for its dedicated circuit. Mechanical and plumbing permits in Bellevue go through the City of Bellevue Development Services. When the work needs a permit, we pull it, schedule the inspection and leave you the paperwork.
Utilities and rebates
Bellevue homes get electricity from PSE, and most have PSE natural gas. Bellevue homeowners may qualify for utility, state or federal rebates. We point you to the current programs for your address before you sign.
