Why Is My Furnace Making a Rattling Noise?
A furnace rattle may follow blower operation or come from a panel, duct, or moving component. Record its timing and airflow pattern; stop for severe noise or safety warnings.
Why Is My Furnace Making a Banging Noise?
A furnace bang can come from ignition, duct expansion, or a blower-related issue. Note its location and timing; stop for gas odor, CO alarms, or a new sharp bang at the furnace.
Why Won’t My Furnace Turn On?
A furnace no-start can involve controls, power, airflow, ignition, or a safety shutdown. Follow safe homeowner checks, recognize gas and carbon monoxide warnings, and prepare for a diagnostic visit.
Why Is My Furnace Blowing Cold Air?
Brief cooler airflow around a startup can differ from a furnace that never delivers heat. Check that the thermostat is set to heat and that the fan is not forced to ON; record whether the burner starts and how long the cool airflow lasts.
