    Run Capacitors and Start Capacitors

    Run capacitors and start capacitors serve different but equally important functions within an HVAC system. A run capacitor helps keep the compressor and fan motors operating efficiently throughout the cooling cycle, while a start capacitor provides the extra burst of energy needed to start certain motors.

    When either component begins to fail, you may notice your air conditioner struggling to start, reduced cooling performance, unusual humming sounds, or frequent system shutdowns. Replacing a faulty capacitor promptly can often prevent additional damage to more expensive HVAC components.

    Quality Capacitors for Residential and Light Commercial Systems

    Caudill Supply carries a variety of HVAC run and start capacitors for air conditioners, heat pumps, packaged units, mini split systems, and other HVAC equipment. Our experienced staff can help identify the proper microfarad rating, voltage, and configuration needed for your specific application.

    Using the correct capacitor helps ensure reliable motor operation, improved system efficiency, and longer equipment life.
