How much does it cost to replace a thermostat professionally?
Professional thermostat replacement typically costs $100–$600 before incentives. Final price depends on thermostat type (programmable vs. smart), integration with HVAC or zoning, wiring needs, and setup/calibration. You may qualify for an instant rebate of over $100 when installed by our Home Energy Auditor, and some eligible Mass Save Home Energy Assessments provide no-cost programmable or smart thermostats. Service available in Weston, MA and nearby cities. A technician will confirm costs on site.
