What is an HVAC Capacitor? 24 Hour Emergency Heating Service Ac Emergency Repair Near Me Weekend Ac Repair Emergency Hvac Service Near Me

An HVAC capacitor is an electrical component that stores energy and releases it in short bursts to start and run motors in the HVAC system. These motors are primarily responsible for powering the compressor, fan, and blower. Capacitors are essential for the proper functioning of the HVAC system, as they provide the necessary electrical boost to overcome the inertia of the motors and keep them running smoothly.
