How much does it cost to replace a thermostat professionally?

Aire Care installs and replaces thermostats, but exact pricing depends on the device (programmable vs. smart), wiring needs (C‑wire), and your HVAC setup (heat pump or conventional). A technician will quote the total after an on‑site check. Members in our maintenance programs get 10% off repairs. One‑time system checks are available if you want us to verify wiring and compatibility first.

Quick checks:

  • Decide if you want Wi‑Fi/app control.
  • Note your system type (heat pump vs. gas/electric).
  • Check for a C‑wire at the thermostat.
