Can I replace my thermostat myself without professional help?

Yes—if it’s a like-for-like swap and the wiring matches, many homeowners can replace a thermostat. Smart models may need a C-wire or adapter, and boilers, zoning, or multi-stage systems require extra care. Our Bloomington and Normal technicians confirm compatibility, install, set up Wi‑Fi, and calibrate, then show you how to use it. If you’re unsure about wiring or app setup, call for help.

Quick checks:

• Turn off power at the HVAC breaker.
• Label each wire and check for a C-wire.
• Follow the wiring diagram, mount, restore power, and test.
