Hiring a licensed professional HVAC technician to replace a standard residential thermostat typically costs between $150 and $350 total, combining standard service call dispatch fees, labor time, and the retail cost of the new thermostat device. If the replacement involves upgrading from an old four-wire setup to a modern smart thermostat requiring a newly pulled common C-wire or complex multi-stage heat pump configuration, total labor costs may increase. Verification: Request an itemized service estimate from a local HVAC contractor before authorizing replacement work.
