VFD, AC & DC Drives

Variable Frequency Drive (VFD) repair and Air Conditioning (AC) systems are closely related in modern HVAC applications. VFDs are used to control the speed of motors in AC units, including compressors, fans, and pumps, enhancing energy efficiency and system performance. When VFDs malfunction, common issues include overvoltage, overheating, capacitor failure, or damaged circuit boards. Repairing a VFD involves diagnostics, replacing faulty components like IGBTs or fuses, and recalibrating the drive for proper operation.

In air conditioning systems, VFDs play a vital role in reducing energy consumption, maintaining precise temperature control, and minimizing mechanical wear. Proper maintenance—such as regular cleaning, monitoring motor loads, and checking for error codes—can prevent major failures. Repair services often include diagnostics, component-level repair, software resetting, and performance testing to ensure the VFD functions reliably within AC systems. With advanced testing equipment and years of hands-on experience, we ensure accurate repairs, minimal downtime, and maximum reliability. We also offer preventive maintenance and VFD system upgrades to improve your energy efficiency and machine performance.
