My furnace is not turning on. What could be the cause of this?

Thermostat Issues: Check for low batteries and see if restarting it will kickstart your system. Issues with your thermostat can cause your unit to frequently cycle on and off.

Tripped Circuit Breaker: The breaker can accidentally be switched off and cut all power to the unit.

Dirty Filter: It is recommended to change your filters at least once a year to maintain peak performance and keep energy costs low. A dirty filter will cause restricted airflow and can cause strain on your furnace.

Unit Failing to Ignite: It could be an issue with the gas supply, pilot light or ignition switch.
