General tips:
- For 3.5 to 5 ton HVAC units, a hard start kit with a capacitance range of 189-227 MFD to 270-324 MFD is required, typically rated for 330 VAC. Common, high-performance, three-wire kits like the CSR-U2 or 5-2-1 Compressor Saver are designed specifically for this range to provide maximum starting torque.
Key Considerations:
- Capacity (MFD/µF): 3.5–5 ton systems usually require 189–227 MFD or 270–324 MFD, depending on the specific model and manufacturer.
- Voltage Rating: Must be rated for at least 330 VAC.
- Kit Type: 3-wire potential relay kits are generally recommended for superior, safer starting performance over 2-wire thermistor kits.
- Compatibility: Designed for single-phase 208/230V systems.
