Can I repair a thermostat myself or should I hire a professional?

You can handle simple thermostat fixes yourself, but wiring or compatibility issues should be left to a pro. Try DIY for settings, Wi‑Fi setup, and batteries. Hire a technician for C‑wire needs, new adapters, multi‑stage or heat‑pump systems, or if wires are loose or mislabeled. Summers Plumbing Heating & Cooling installs and calibrates smart thermostats, integrates Alexa/Google/Apple, and verifies operation with your HVAC during tune‑ups in Bloomington and Normal.

Quick checks:

• Replace batteries and verify mode/temperature.
• Check Wi‑Fi/app login and router signal.
• Confirm breaker is on and schedule isn’t overriding.
