What that Loud Bang could be in Your HVAC

If you have a gas furnace/cooling system, and you hear a bang each time it starts up, you may have a problem with delayed ignition. It could mean the crossover tube alignment is off or that your igniter needs replaced. It happens because the gas is not igniting right away and a small amount of it accumulates. When enough gas accumulates and reaches the flame source, you hear the bang as it ignites. Delayed ignition can also be caused by low gas pressure, dirty burners, a dirty or weak pilot, or a restricted draft inducer. It takes a trained professional to determine what is causing your bangs.
