How much does it cost to rewire a thermostat professionally?

Professional thermostat rewiring is quoted after an on-site diagnostic; there isn’t a flat price. A Green Air Care technician will inspect the circuit, confirm compatibility, and give a written quote in Chicago or Evanston. Cost depends on thermostat type, wire run and access at the furnace/air handler, and any calibration, app setup, or parts. We offer same-day service when available, free estimates on replacement quotes, financing options, and maintenance plans that include a 30% repair discount and no overtime fees.
