How much does it cost to replace a thermostat professionally?

Professional thermostat replacement is quoted after an in‑home evaluation. Final cost depends on the thermostat model (Ecobee, Nest, Amazon), system compatibility, and any wiring needs such as adding a C‑wire. A technician will confirm compatibility with furnaces, boilers, heat pumps, or zoned systems, then install, program the app, and calibrate. If your system lacks a C‑wire, we can install one. We also include thermostat testing during routine tune‑ups and can advise on available incentives in areas like Schaumburg and Glendale Heights.
