Experienced troubleshooting and service for Variable Refrigerant Flow systems. LG, Mitsubishi, Daikin, Samsung, and Hitachi expertise.
Variable Refrigerant Flow systems are powerful, efficient, and increasingly popular in commercial buildings—but they’re fundamentally different from conventional HVAC. The refrigerant piping is more complex, the controls are more sophisticated, and diagnosing problems requires specific training and experience.
Many commercial HVAC contractors don’t have VRF expertise. They may attempt service anyway, leading to misdiagnosis, improper repairs, and frustrated building owners.
Burris Mechanical Group has hands-on experience with VRF systems from multiple manufacturers. We understand how these systems work, how to troubleshoot them, and how to maintain them for long-term reliability.
We provide service and troubleshooting for VRF systems from:
LG Multi V Service, troubleshooting, and maintenance for LG’s commercial VRF lineup.
Mitsubishi City Multi Experienced support for Mitsubishi’s widely-installed City Multi systems.
Daikin VRV Service for Daikin VRV systems, including older and current generation equipment.
Samsung DVM Troubleshooting and service for Samsung’s Digital Variable Multi systems.
Hitachi Set Free Support for Hitachi’s Set Free VRF product line.
VRF systems use long refrigerant runs with multiple indoor units. Finding leaks, managing oil return, and maintaining proper charge requires specific knowledge.
Zone controls, scheduling, and integration with building management systems. We understand how to configure and troubleshoot VRF controls.
Each VRF manufacturer has different diagnostic procedures, error codes, and service requirements. We know the differences.
VRF service requires specific diagnostic equipment and refrigerant handling tools. We have the right equipment for the job.
VRF error codes can be cryptic, and symptoms don't always point to the real problem. We use manufacturer diagnostic tools and our experience to identify issues correctly.
Once we've identified the problem, we complete repairs using proper procedures. VRF systems have specific requirements for brazing, pressure testing, and refrigerant handling.
Regular maintenance keeps VRF systems running efficiently and helps prevent costly failures. We perform manufacturer-recommended maintenance procedures.
If you're installing a new VRF system, we can provide commissioning support to ensure proper startup and configuration.
VRF systems have extensive control options. We can help optimize settings for comfort and efficiency.
VRF systems are commonly installed in:
If you manage or own a building with VRF equipment, we can help keep it running properly.
If your VRF system isn’t performing or you need a contractor who actually understands these systems, give us a call.
