You can replace a basic, like-for-like thermostat yourself if you turn off power, label wires, and follow the wiring diagram. For smart controls, heat pumps, multi‑stage systems, or when a C‑wire is unclear, it’s safer to use a pro in Roanoke or Cave Spring.
Quick checks:
- Turn off HVAC power at the breaker.
- Photograph and label each wire.
- Confirm system type (heat pump vs. furnace) and C‑wire.
- Mount level and set correct system settings.
