Common Heating System Failures

Heating equipment failures usually exhibit clear technical indicators:

Furnace Runs But Produces No Heat: The indoor blower fan circulates cold air while the gas burner fails to light. Read our diagnostic guide on furnace not heating causes.
System Cycling On and Off Rapidly: Short-cycling caused by a dirty air filter restricting airflow or a tripped high-limit thermal switch.
Unusual Combustion Odors: A burning dust smell on initial winter startup is normal, but persistent gas or sulfur odors require immediate shutdown and service.
Thermostat Unresponsive: Complete lack of communication between digital wall controls and the heating control board. See our troubleshooting guide on system power failure troubleshooting.

Frequently Asked Questions

Common questions about heating, cooling, scheduling, and service dispatch in Montebello CA.

Why is my heating system blowing cold air?

Heating systems blow cold air if the furnace burner fails to ignite, the flame sensor is dirty, the gas valve is shut off, or the thermal high-limit switch has tripped due to an overheated heat exchanger.

Is a squealing sound from my heater dangerous?

A squealing noise usually indicates a slipping blower belt or worn motor bearings. While not immediately explosive, it should be serviced promptly to prevent complete blower motor lockup.
