Mini-Split Installation in Graham, WA

Yes. The mechanical permit is issued by Pierce County Planning & Public Works (Graham is unincorporated Pierce County), and Washington State requires one for this work. We handle the whole thing — application, fee, and meeting the inspector for the final — so you never contact the permit desk yourself. Every install meets or exceeds the current Washington State mechanical and energy codes.

Most single-zone mini-split installations in Graham are completed in one day. Multi-zone systems typically take one to two days depending on the number of indoor units and the complexity of the installation.

Graham is served by Puget Sound Energy, so the program that applies to your home is PSE: up to $4,400 toward a qualifying heat pump replacing an existing electric or fossil-fuel system — the exact amount depends on what you are replacing and the equipment you install. The base electric-resistance conversion is $1,500, with a $2,400 income-based Efficiency Boost on top for households that qualify — rural electric-furnace homes qualify more often than in-town gas homes. Rebate programs change, and eligibility turns on your existing heating system, the equipment's efficiency rating and sometimes your household income — we confirm what you actually qualify for before it goes in your quote, and we file the paperwork after the install. The federal 25C tax credit expired on December 31, 2025, so do not budget around it.

Graham is not listed in the state energy code's design-temperature table, so the nearest station — Puyallup, at 19°F — is the starting point (WAC 51-11C-80100, Table C-1), but Graham sits higher and further inland than the Puyallup station and holds snow the valley misses, so we design to a colder number. That is the number a Manual J load calculation for your home is run against, and it is the difference between equipment that carries the house on its own and equipment that leans on expensive backup heat every cold snap. A cold-climate heat pump holds its rated capacity well below that, which is why heat pumps genuinely work here rather than being a compromise. Gas here comes from Puget Sound Energy where the mains reach, propane everywhere else, and for some homes a hybrid — heat pump for most of the year, gas furnace for the coldest mornings — is the right answer. We will tell you if it is.
