- Suitable for use with compressors, condenser fan motors, and blower motors
- Designed for residential and light commercial HVAC systems
Why Run Capacitors Matter
Run capacitors provide the continuous phase-shifted current needed to keep single-phase motors running smoothly and efficiently. A properly rated capacitor reduces motor amp draw, minimizes heat buildup, and helps prevent premature motor failure — making timely replacement critical to system reliability.
Application
- Air conditioning condensing units
- Heat pump systems
- Condenser fan motors
- Blower and air handler motors
