How much does it cost to replace a thermostat professionally?

Professional thermostat replacement cost varies by model and system, and we confirm exact pricing on site after inspection. Factors include smart vs. basic thermostat, wiring/C‑wire needs, placement or relocation, compatibility with heat pumps/boilers/mini‑splits, and programming/zone integration. Most installations in Franklin homes take 30–90 minutes. Every install includes a 2‑year warranty (4 years for Priority Plan members). Mass Save smart‑thermostat rebates may offset your cost, and we guide you through eligibility. You’ll get straightforward, upfront pricing before work begins.
