Homeowner Guide
If the heat is not working, start with the simple observations: thermostat setting, filter condition, whether the blower runs, and whether the furnace tries to start. Stop testing and use the right emergency path if you smell gas, see smoke, or notice a hot electrical smell.
Make sure the thermostat is set to Heat and the set temperature is above the room temperature. If the display is blank, misreading, or the system does not respond, that is useful to mention. A clogged filter or blocked return can also make heating symptoms worse, especially if the furnace starts and then shuts back down.
Tell Scott whether the furnace is silent, the inducer starts, the blower runs, the burners light and then stop, or the system cycles repeatedly. Those details help separate thermostat, airflow, ignition, safety, blower, and control problems before anyone guesses at a part.
If you smell gas, leave the area and contact the gas utility or emergency services. If you notice smoke, arcing, burning plastic, a hot electrical smell, or a breaker that trips again, shut the system off and stop resetting it. For normal no-heat symptoms, request the $95 Springfield Diagnostic. Nearby towns may cost more.
