Smart Thermostat C-Wire Installation

Install a C-wire so your Nest, Ecobee, or Honeywell smart thermostat works perfectly.

Smart Thermostat C-Wire Installation

Smart thermostats require a C-wire (common wire) for continuous power. Many older homes lack one. We run the C-wire from your air handler or furnace to the thermostat location.

What's included

  • C-wire installation from HVAC equipment to thermostat
  • Compatible with all smart thermostat brands
  • Nest, Ecobee, Honeywell, and more
  • Same-day service available
  • Permit coordination if applicable

Good fit if you have…

  • Smart thermostat won't install or behaves erratically
  • Thermostat shows low battery constantly
  • HVAC system has only 2 or 4 wires at thermostat
  • Upgrading from old thermostat to smart model

Pricing: $150–$350 installed
