York S1-324-35886-000 2-Stage ECM Dual Air Pressure Switch Kit 96%

The York, S1-324-35886-000 Dual Air Pressure Switch Kit is the component required to enhance the efficiency of the two-stage ECM variable speed furnaces with 96% efficiency. This kit also has a dual pressure switch that is supposed to monitor and manage the airflow of the HVAC system. It is, in effect, an effector of efficiency and safety. The kit ensures correct pressure measurements of air at specified furnace locations to ensure correct combustion, heat exchange, and ventilation. Many problems such as system failure, reduction in heating efficiency, and even compromise of safety may be caused by a faulty pressure switch. The kit consists of two pressure switches each of which is set to respond at different pressures.
