Why Draft Inducers Matter
Draft inducers are essential safety and efficiency components in modern furnaces. By creating a controlled negative pressure zone, they ensure combustion gases are fully evacuated before the next ignition cycle, reducing the risk of carbon monoxide buildup and improving overall combustion efficiency. A failing draft inducer can trigger pressure switch lockouts and prevent the furnace from firing — making timely replacement critical.
