Fast, accurate chiller diagnostics using advanced testing equipment. We identify the root cause — not just the symptoms — so your system gets fixed right the first time.

We take a systematic approach to chiller diagnosis — no guesswork, no unnecessary part replacements.

We measure cooling capacity, energy consumption, and temperature differentials to establish a baseline and identify deviations.

Each major component — compressor, condenser, evaporator, expansion valve — is tested individually to isolate faults.

We check sensors, controllers, and wiring for faults that can cause erratic behavior or complete system shutdown.
