Mini-Split Installation in Sammamish, WA

Mini-Split Installation in Sammamish: what's different here
Most Plateau homes were built from the 1980s onward, so many are on their first or second furnace and AC and have the ductwork to take a heat pump. In newer Sammamish homes, a mini-split usually handles one problem room, like a hot upstairs bedroom or a bonus room over the garage, without changing the main system.
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 Sammamish go through the City of Sammamish Permit Center. When the work needs a permit, we pull it, schedule the inspection and leave you the paperwork.
Utilities and rebates
Sammamish homes get electricity from PSE, and most have PSE natural gas. Sammamish homeowners may qualify for utility, state or federal rebates. We point you to the current programs for your address before you sign.
