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

You can handle basic checks yourself, but call a professional if wiring, compatibility, or irregular furnace/AC cycling is involved. Our technicians diagnose thermostat faults that cause gas furnaces to turn on or off irregularly, and we can replace or install a new thermostat during the same visit with no-pressure options and free estimates.

Quick checks you can do:

• Replace thermostat batteries.
• Verify mode, temperature, and schedule.
• Check the breaker and furnace/AC power switch.
• For smart models, confirm Wi‑Fi and app settings.
