An HVAC start capacitor is a small electrical component used in heating, ventilation, and air conditioning (HVAC) systems to assist in the starting of the compressor motor. It stores and releases electrical energy to provide an extra boost of power during the initial startup phase, helping the compressor overcome inertia and start efficiently. Start capacitors are characterized by by their black plastic housing and cylindrical shape. They typically have two wire terminals for connections. Over time, start capacitors may wear out or fail, requiring replacement to ensure the HVAC system continues to function effectively.
