Special Features

  • 5-2-1 HARD START TECHNOLOGY This CSR-U2 hard start kit cuts the initial power surge by 50% to lower load on AC compressor motors and prolong service life. Supporting dual 370/440VAC voltage, this AC hard start capacitor delivers stable startup performance for all types of residential air conditioners and HVAC systems. It effectively avoids circuit overload and keeps consistent airflow during peak cooling periods for energy-efficient daily operation.
  • PRE-WIRED FOR EASY INSTALLATION Our compressor saver comes with factory pre-assembled capacitor and clearly labeled color-coded wires. Equipped with corrosion-resistant screws and heavy-duty zip ties, no soldering or complicated wiring is required. Only 3 wires need simple connection, helping you finish installation quickly even in the tight space of condenser units. A detailed step-by-step guide is included for hassle-free setup.
  • WIDE COMPATIBILITY FOR 3.5-5 TON UNITS This HVAC hard start capacitor kit is universally designed for 3.5, 4 and 5 ton air conditioner compressors. It works perfectly with mainstream brands including Carrier, Trane and Lennox, fitting most American residential central AC units. Adopting durable nylon housing, it resists high heat and vibration to adapt to various harsh working environments.
  • HEAVY-DUTY & LONG LASTING Manufactured with premium UL-certified materials, this replacement CSR-U2 compressor saver meets US safety standards. It greatly reduces startup amp draw and compressor wear, extending the lifespan of your air conditioner compressor and related electrical parts. Reliable construction cuts down expensive after-sales repair and replacement costs for long-term use.
  • COMPLETE KIT & PROFESSIONAL USE The all-in-one hard start kit includes pre-charged AC capacitor and all mounting hardware for immediate use. Note that professional installation by a licensed technician is recommended. We provide sincere customer service, please contact us once you meet any problems, and we will respond and offer effective solutions within 24 hours.
