How much does it cost to rewire a thermostat professionally?

Professional thermostat rewiring costs depend on your system and wiring needs. A technician confirms final pricing after an on‑site inspection. Many jobs involve adding a C‑wire for continuous power, and older or zoned systems may require adapters or extra setup. We provide compatibility checks, professional wiring, and upfront pricing before work starts in Glendale Heights and nearby areas.

Quick factors that affect price:

• Adding a C‑wire or adapters
• System type (furnace, boiler, heat pump, mini‑split)
• Zoning and smart‑home integration needs
