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

Yes, you can handle simple thermostat checks yourself, but hire a professional for wiring, replacements, or smart-home integration. DIY fixes cover settings and power; pros handle compatibility, control wiring, and system diagnostics.

Quick checks:

• Replace batteries or verify power to the thermostat.
• Confirm mode, temperature, and schedule settings.
• Check breaker and furnace/air handler switch is on.
• For smart models, reconnect Wi‑Fi and app.
• If the display is dead or the system short-cycles, call a technician.
