Engineering-First Diagnostics

As a fourth-generation family of engineers with 80+ years in engineering, we apply fundamentals before swapping parts. Our diagnostics combine instrumented testing with design insight to isolate true failure points.

• Data-driven analysis of pressures, temperatures, and superheat/approach
• Non-invasive electrical testing of inverters, contactors, and boards
• Nitrogen pressure testing, deep evacuation with micron verification, and moisture control
• Electronic leak detection and soap-bubble verification at suspected joints
• Airflow and static pressure measurements to correct system-side causes
• Control logic review, addressing checks, and setpoint optimization

This method restores reliability, reduces callbacks, and protects the longevity of your VRF investment.
