How much does it cost to replace a thermostat professionally?

Professional thermostat replacement pricing varies by thermostat type (manual, programmable, or Wi‑Fi/smart), existing wiring, and how it integrates with your HVAC. A Brothers technician will inspect and provide an upfront price before work begins. You can apply our $50 Off thermostat services coupon (expires 2025-12-31). Home Care Club members get a 10% repair discount and a 2‑year warranty on all work (drain work excluded). We install and program thermostats in Denver and nearby cities.
