How much does it cost to replace a thermostat professionally?

There isn’t a one-size price for thermostat replacement. Cost depends on the thermostat type (standard programmable vs. Wi‑Fi/smart), wiring needs (adding a C‑wire or wall plate), and setup/training time. A technician will assess compatibility and confirm the total before work begins. Members get $49 HVAC diagnostic pricing, and 15% off eligible repairs. If you’re upgrading your whole Lennox system, rebates may apply and require a qualifying thermostat. We serve homes across Roanoke and nearby communities.
