How much does it cost to replace a thermostat professionally?

There isn’t a single price; professional thermostat replacement cost depends on the thermostat type (standard vs. smart), wiring condition, and your HVAC setup. We perform on-site diagnostics, explain options upfront, and apply an $89 HVAC Tune-Up Diagnostic that is waived with service. Eligible rebates can lower your net cost, including SRP smart thermostat rebates up to $100 and an APS $30 bill credit. APS also offers a $50 rebate for qualifying home energy monitors. We serve Phoenix and surrounding cities.
