A Capacitor is a small electrical component that stores an electrical charge and provides a "boost" to start motors or keep them running smoothly. In older HVAC systems, a failing capacitor is one of the most common reasons for a system not starting. Our modern Alpic Eco systems with Inverter Technology rely less on traditional start-capacitors, but they are still present in many fan and blower circuits. If your Single-Zone unit hums but doesn't start, the capacitor may need replacement. We stock high-quality OEM capacitors and other electrical Components to keep your system in top shape. It is a low-cost part that plays a high-value role in the electrical "Health" of your Multi-Zone system. Regular maintenance by a professional can identify a weakening capacitor before it fails completely. This proactive approach is key to maintaining "Reliability" during a heatwave.
