Expert Variable Frequency Drive Service That Keeps Motors Running
VFD SERVICE & REPAIR
Variable frequency drives control the motors at the heart of your HVAC and process equipment. Flo Mechanical Solutions provides skilled VFD repair, parameter programming, and motor control service that keeps drives reliable, efficient, and properly protected.
Variable Frequency Drive Service for Industrial Equipment
Variable frequency drives are everywhere in modern facilities, controlling pumps, fans, compressors, and air handlers to save energy and match output to demand. But a VFD is also a sophisticated piece of power electronics, and when it faults, the equipment it drives stops. Flo Mechanical Solutions brings the motor control expertise needed to diagnose, repair, and program drives correctly.
Our technicians read and interpret fault codes, test power and control circuits, and determine whether a drive needs repair, reprogramming, or replacement. We commission drives by setting motor nameplate data, acceleration and deceleration ramps, current limits, and protection parameters so the drive matches both the motor and the application. Proper programming is the difference between a drive that protects your motor and one that nuisance-trips or lets equipment fail.
We also address the broader electrical picture. Drives generate harmonics that can disturb power quality and stress other equipment, so we assess harmonic issues and recommend mitigation. We configure motor protection, verify cooling and filtering, and ensure the installation supports reliable long-term operation.
Locally owned and based in West Valley City, we serve industrial plants, commercial buildings, and process facilities throughout the Salt Lake City metro and Utah. Licensed, insured, and available 24/7, we keep your motor-driven systems online.

OUR SERVICE PROCESS
Fault Assessment
We capture fault codes and operating conditions to understand how and why the drive is failing.
Electrical Diagnosis
Our technicians test power and control circuits to isolate the root cause within the drive or system.
Repair or Replacement
We repair the drive when practical or recommend a properly matched replacement when it is the better choice.

FAQ
FREQUENTLY ASKED QUESTIONS
Answers about VFD repair and variable frequency drive service in Utah
A VFD controls the speed and torque of an AC motor by varying the frequency and voltage supplied to it. This lets pumps, fans, and compressors match output to demand, which saves energy and reduces mechanical stress on the equipment.
Nuisance trips often stem from incorrect parameter settings, overcurrent or overvoltage conditions, overheating, or power quality problems. We interpret the fault code and test the circuit to identify the true cause rather than just resetting the drive.
It depends on the drive age, fault type, parts availability, and cost. We give an honest recommendation, repairing when it is practical and replacing with a properly matched unit when that delivers better long-term reliability and value.
Programming sets how the drive controls and protects the motor, including ramps, current limits, and trip thresholds. Correct parameters prevent nuisance trips and equipment damage, while poor programming can shorten motor life or cause failures.
VFDs draw current in a non-linear way that injects harmonic distortion back into the electrical system. Excessive harmonics can overheat transformers, disrupt sensitive equipment, and cause unexplained faults. We assess and recommend mitigation such as line reactors or filters.
Yes. We service variable frequency drives across HVAC and process applications, including pumps, fans, air handlers, and compressors, and we tune each drive to its specific load for reliable, efficient operation.
We provide 24/7 emergency response across the Salt Lake City metro and Utah. When a drive fault stops critical equipment, our local technicians respond quickly to diagnose and restore operation.
Yes. When a drive is obsolete or unsupported, we size and select a modern replacement, integrate it into your system, program it for your application, and fully commission it so the equipment runs as intended.
