A standard thermostat installation takes 30 to 60 minutes. Smart thermostat installs that require a new C-wire run, wiring upgrade, or HVAC compatibility tweak can take 1 to 2 hours. We typically schedule thermostat installs as 1-hour appointments and include a homeowner walkthrough so you can use every feature.

Typical timing

  • Like-for-like swap — 30–45 minutes
  • Smart thermostat with existing C-wire — 45–60 minutes
  • Smart thermostat with new C-wire run — 1.5–2 hours
  • Heat-pump or zoned system upgrade — 1.5–2.5 hours
