Product Details

Description

This premium Air Pressure Switch with Bracket is an essential safety and functional component for HVAC systems, including residential furnaces and air handlers. Commonly referred to as an air proving switch, its primary function is to monitor the pressure differential created by the draft inducer or blower motor. By ensuring that proper airflow is established before allowing the heating or cooling sequence to begin, this switch prevents hazardous operation and system inefficiencies. If your HVAC unit is failing to ignite or experiences frequent cycle interruptions, a malfunctioning pressure sensor may be the cause. This replacement part includes a pre-attached mounting bracket for a secure, stable installation and is built with high-quality materials to ensure long-lasting performance in demanding environments.
