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

You can handle simple thermostat fixes yourself, like replacing batteries, checking settings, or rebooting the device. For wiring issues, C‑wire installation, system compatibility checks, or smart thermostat setup, hire a professional. Our technicians confirm compatibility, safely add a C‑wire when needed, and integrate the thermostat with your HVAC and app for reliable operation.

Quick checks:

• Replace batteries and verify date/time and mode.
• Check the breaker and furnace/air handler power switch.
• Confirm Wi‑Fi connection and app login.
