Hard Start Capacitors

    Hard start capacitors, also known as start assist devices or hard start kits, are electrical components used in HVAC systems to aid in the starting process of compressors and motors. These capacitors provide an extra boost of power during the starting phase, helping overcome the initial resistance and inertia of the motor or compressor. By reducing the strain on the electrical system during startup, hard start capacitors extend the life of the equipment and improve overall performance. They are particularly useful in situations where the power supply may be limited or when the system experiences repeated starting issues. Hard start capacitors are commonly used in air conditioning units, refrigeration systems, and heat pumps, enhancing their reliability and efficiency.

    Renowned brands like MARS, Lennox, Sealed Unit Parts, and DiversiTech are among the leading manufacturers of high-quality hard start capacitors. These brands offer a wide range of hard start kits designed to fit various HVAC systems and compressor models. Whether it's a residential or commercial application, customers can find the right hard start capacitor to optimize their equipment's performance.
