Mercer Island's housing stock spans 1950s bridge-era ranches to newer lakefront rebuilds, so electrical panels and ductwork vary widely from house to house. Puget Sound Energy supplies both electric and gas service on the island, and marine air off Lake Washington adds humidity that stresses older heat pumps and mini splits. SPS Pro Services has worked on both original and updated Mercer Island homes since 2017, matching equipment sizing and permit steps to what your house actually has installed.

About serving Mercer Island
Things about Mercer Island that shape almost every job we run here.
Mercer Island is served by Puget Sound Energy (PSE) for both electricity and natural gas, unlike some Snohomish County areas covered by Snohomish PUD.
A large share of Mercer Island homes were built during the 1950s-1970s bridge-era boom, meaning original 60-100 amp electrical panels are still common and often undersized for modern heat pumps or EV chargers.
Surrounded by Lake Washington, the island sees higher humidity and more wind exposure than inland King County neighborhoods, which affects mini split placement and heat pump defrost cycles.
Mercer Island homeowners ask us
Do you pull permits for HVAC and electrical work on Mercer Island?
Yes. The City of Mercer Island requires permits for furnace and heat pump replacements, mini split installs, and most panel or circuit work. SPS Pro Services pulls these permits under our Washington L&I contractor registration and schedules the required inspections, so you're not left coordinating with the city yourself.
What does a service call in Mercer Island cost?
Service calls start at $129, which covers a technician diagnosing the issue on-site, whether it's a furnace, heat pump, mini split, water heater, or electrical panel. If you approve the repair the same day, that visit fee typically applies toward the total job cost.
What's different about wiring in older Mercer Island homes?
Many homes built from the 1950s through 1970s still have original 60-100 amp panels, which aren't rated for modern heat pumps, mini splits, or EV chargers. Our electricians check panel capacity before any HVAC install and upgrade service size when needed to meet current NEC and Washington L&I code.
Do you work on both gas and electric systems on Mercer Island?
Yes. We service natural gas furnaces, electric heat pumps, and hybrid systems tied to Puget Sound Energy accounts, plus gas and electric water heater repair, replacement, and installation, all permitted and inspected to Washington State code.
