The most common causes of heating failure in Spring TX are: thermostat set to COOL or FAN instead of HEAT, tripped circuit breaker, clogged air filter triggering the limit switch shutoff, failed igniter on a gas furnace, dirty flame sensor causing repeated shutdowns, or a failed control board. Check thermostat settings and the air filter first — both are free fixes that resolve many calls.
Check in this order: (1) Thermostat — set to HEAT mode with setpoint above current room temp. (2) Circuit breaker — check both the furnace breaker and air handler breaker. Reset once if tripped. (3) Air filter — a clogged filter triggers the limit switch and shuts the furnace down. Replace if dirty. (4) Is the furnace trying to start? Listen for ignition attempts. If yes but no heat — likely igniter or flame sensor. If silent — check power and thermostat wiring.
If the furnace is completely silent when the thermostat calls for heat — check electrical: breaker, thermostat batteries, thermostat wiring. If the furnace is attempting to start (you hear clicking, a brief flame, then shutdown) — it's likely a gas system issue: igniter, flame sensor, gas valve, or control board. These require a licensed technician.

Yes — a severely clogged filter restricts airflow to the point where the heat exchanger overheats and trips the high-limit safety switch. The furnace shuts off as a safety measure. Replace the filter and wait 10–15 minutes before restarting. If the furnace starts normally after filter replacement — that was the cause. If it trips again — a technician needs to inspect the limit switch and heat exchanger.
