Smart Thermostat Installation in Bellevue, WA
Nest, Ecobee, and smart thermostat installation and programming for Eastside homeowners — wired correctly to your HVAC system for Bellevue homeowners.

Smart Thermostat Installation in Bellevue: what's different here
Ranch and split-level homes in Lake Hills and Crossroads from the 1960s and 1970s often still have their first duct layout, and the hillside homes in Somerset run long duct and line-set paths between floors. Older Bellevue 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.

Swapping a thermostat usually does not need a permit; adding new wiring or a circuit can. Mechanical and plumbing permits in Bellevue go through the City of Bellevue Development Services. When the work needs a permit, we pull it, schedule the inspection and leave you the paperwork.
