Newcastle sits in King County, and any furnace, heat pump, or AC swap here needs a permit pulled either through the City of Newcastle or King County, depending on your parcel. Washington State L&I also requires licensed electrical contractors for any wiring tied to HVAC equipment, including disconnects, dedicated circuits, and heat pump hookups. We handle the permit paperwork and inspections as part of the job so homeowners aren't left navigating code requirements on their own.
Local knowledge
What's different about hvac services in Newcastle
Local housing stock and utilities in Newcastle change what this work involves.
Newcastle's mix of newer construction near Newcastle Golf Club and older homes near Coal Creek and Lake Boren means duct systems and electrical panels vary widely in age, which changes what permits and code upgrades a job requires.
PSE provides electric service to Newcastle, and heat pump installs or panel upgrades often require coordination with PSE for service capacity before the city will sign off on a permit.
The hilly terrain around Coal Creek Parkway and May Creek puts some Newcastle homes in higher-wind exposure zones, which affects outdoor unit placement and mounting requirements under current code.

Straight answers
HVAC Services in Newcastle — FAQ
Does a furnace or heat pump replacement in Newcastle require a permit?
Yes. Newcastle requires permits for furnace, heat pump, and AC replacements, and the city or King County will require an inspection before the job is considered complete. We pull the permit and schedule the inspection as part of the installation, so there's no separate step for the homeowner to manage.
Who handles electrical work for HVAC in Newcastle, WA?
Washington State L&I requires a licensed electrical contractor for any wiring related to HVAC systems, including new circuits for heat pumps or mini-splits. Our electricians handle this directly so the electrical and mechanical inspections can both pass without a second contractor involved.
How fast can someone come out to a Newcastle home?
Most Newcastle service calls get scheduled within a day or two of the call, depending on the day of the week. We also serve Bellevue, Redmond, Kirkland, Sammamish, and Seattle, so routing a technician through Newcastle on a given day is usually straightforward.
Do older homes near Coal Creek need extra work before a new system goes in?
Some of the older homes near Coal Creek and Lake Boren have electrical panels or ductwork that predate current code, which can mean added work to bring the system up to Washington State L&I standards. We flag this during the diagnostic visit so there are no surprises once the permit is pulled.
