How much does it cost to replace a thermostat professionally?

Professional thermostat replacement cost depends on the thermostat type and your HVAC wiring. A Summers technician will assess compatibility, C-wire needs, and any adapters, then confirm the total price before work begins. Smart models can include Wi‑Fi setup, Alexa/Google/Apple integration, and calibration. Many Bloomington and Normal homeowners pair installation with a tune-up, where we test and calibrate the thermostat. You may qualify for the Energy Efficient Home Improvement Credit of up to 30% of the purchase, up to $1,200, on eligible models.
