How much does it cost to rewire a thermostat professionally?

The cost to professionally rewire a thermostat varies by your HVAC setup and wiring access. A Summers technician will confirm pricing after an in‑home inspection. We assess C‑wire needs, recommend adapters if required, and ensure the new control matches your system. If you also install a qualifying smart thermostat, you may claim up to 30% of the purchase, up to $1,200 annually.

Quick factors that affect cost:

• C‑wire run or adapter
• Attic/basement access and wire length
• Zoning or multi‑stage equipment
• Wi‑Fi and smart‑home setup

We serve Bloomington, Normal, and nearby communities.
