JLM Mechanical specializes in the installation, service, repair, and replacement of complex VRF and VRV HVAC systems for commercial, hospitality, multi-family, and other large-scale applications.

Our team handles the full process, including equipment installation, refrigerant piping, branch controllers, indoor fan coils, controls, pressure testing, evacuation, refrigerant charging, startup, and system commissioning. We also troubleshoot existing systems using manufacturer diagnostic tools when needed to identify communication issues, refrigerant problems, failed components, and performance concerns.

From replacing a single fan coil or control board to completing a full VRF system changeout, JLM Mechanical focuses on clean piping practices, accurate diagnostics, proper commissioning, and reliable long-term system operation.
