Our Diagnostic Process

We start with a structured checklist and instruments: airflow and static pressure readings, temperature and humidity profiling, electrical testing under load, VFD parameter review, and control sequence verification. We then document findings and propose a clear repair plan with options and timelines.

Expect precise work, tidy service areas, and OEM‑grade parts. We aim to restore capacity quickly and safely while extending the useful life of your AC PRO AHU.
