This is a common local issue often caused by incorrect wiring during installation, a weak Wi-Fi signal near your thermostat, or a firmware update conflict.

Furnace ignition failure is a frequent winter problem here, typically due to a faulty hot surface ignitor or flame sensor—components that wear out over time.

We perform a thorough diagnostic to pinpoint the exact cause, whether it's a simple cleaning of the sensor or a part replacement, to restore safe, reliable heat to your home.
