Can I replace my thermostat myself without professional help?

You can replace a basic thermostat yourself, but smart models are safer and more reliable with professional installation. Many systems need a C-wire for continuous power; if yours lacks one, a technician can add it. Pros verify compatibility with furnaces, boilers, heat pumps, zoned systems, and older equipment, then handle app setup. Summers Plumbing Heating & Cooling offers end-to-end selection, installation, and testing, and includes thermostat checks during tune-ups in Glendale Heights and Schaumburg.

Quick checks:

  • Confirm model compatibility.
  • Cut power and label wires.
