Smart Thermostat Installation in Mercer Island: what's different here
Elevation on the island runs from about 18 feet at the lakefront to almost 400 feet near the ridge, so equipment placement, condensate drainage and access change from block to block. Older Mercer Island homes often lack the C-wire smart thermostats need, or have line-voltage baseboard heat that needs a special thermostat. We fix the wiring as part of the install.
Permits and inspections
Swapping a thermostat usually does not need a permit; adding new wiring or a circuit can. Mechanical and plumbing permits in Mercer Island go through the City of Mercer Island Permit Center. When the work needs a permit, we pull it, schedule the inspection and leave you the paperwork.
