Thermostat Installation in Seattle: Digital, Smart & Wi-Fi Thermostats
Thermostat installation is a small job that changes how your whole HVAC system runs. Fuse Service installs digital, programmable, smart, and Wi-Fi thermostats for homes and businesses across Seattle and King County — and makes sure the new thermostat actually matches your furnace, heat pump, or air conditioner.
What’s Included
We check your wiring and confirm the thermostat is compatible with your system, including heat pumps and multi-stage equipment. Then we mount and wire the new thermostat, set up your schedule and Wi-Fi, and walk you through the app before we leave.
If the old thermostat was hiding a problem with the system itself — short cycling, a stuck relay, a heat pump running on backup heat — we tell you what we found instead of just swapping the device.
Smart Thermostats and Heat Pumps
Many smart thermostats need a C-wire to stay powered, and heat pumps need the right auxiliary-heat settings so they don’t lean on expensive backup heat. We set both up correctly. If you are choosing a model, ENERGY STAR certified smart thermostats are a good place to start. Planning a new system? See heat pump installation.
