MaxiHVAC AC909 Advanced A/C Diagnostic System

Instead of relying on pressures alone, the AC909 delivers visual analysis of the entire thermal management system by combining refrigerant data with vehicle diagnostics, airflow, temperature, electrical, and sensor information. Graphical diagnostics combine live refrigerant pressures, temperatures, humidity, and system measurements into a single analysis screen. Illustrated, step-by-step procedures help technicians isolate faults and verify repairs, with dedicated diagnostics for compressors, evaporators, condensers, metering devices, and system blockages. Leak testing, refrigerant service, and live vehicle diagnostics are combined in one guided workflow. Designed for electronically controlled A/C systems, hybrids, EVs, advanced heat pumps, and evolving refrigerant technologies, the AC909 helps reduce guesswork, avoid unnecessary repairs, and improve first-time fix confidence. Confirm sealing integrity, moisture removal, and refrigerant charge with integrated nitrogen testing, precision micron measurement, and live system verification.
