The Autel MaxiHVAC AC909 brings leak testing, refrigerant service, and live vehicle diagnostics together in one intelligent workflow-giving technicians complete system visibility to diagnose, repair, and verify with confidence.
Features an intuitive tablet interface with step-by-step illustrated guided workflows that seamlessly connect leak testing, refrigerant service, and live vehicle diagnostics. By fusing real-time refrigerant pressure, temperature, and humidity with OBD sensor data—such as blend door functionality and outlet temperatures—onto a single analysis screen, the system delivers complete thermal system visibility. Through advanced multi-parameter graphical correlation and automated anomaly detection, technicians can easily pinpoint component defects, eliminate operational errors, and significantly increase first-time fix rates.
Confirm system tightness, moisture removal, and refrigerant charge using integrated nitrogen testing, precision micron measurement, and live system verification.
Designed for today's electronically controlled A/C systems, hybrids, EVs, advanced heat pumps, and evolving refrigerant technologies. AC909 seamlessly integrates flow control valve actuation with A/C diagnostics, recovery, and recharging. Master complete EV thermal management diagnostics with a single, powerful device.
Yesterday's A/C Is Today's Thermal Management System

Professional tablet for A/C & Thermal management, wirelessly connecting with related accessories for quick, accurate, and comprehensive vehicle A/C servicing.

A wireless 4-port manifold gauge featuring an integrated vacuum gauge and a large sight glass for visual refrigerant inspection. Designed to work seamlessly with the Autel AC909, it measures, calculates, and displays live pressure, temperature, and vacuum readings.

A dedicated diagnostic tool for vehicle compressors, capable of identifying internal compressor faults as well as faults in associated wiring harnesses and the ECU.

Clamped onto the surface of the vehicle's AC refrigerant pipe to measure the temperature at the clamping point. Connects to the AC909 via Bluetooth.

Measures ambient temperature and humidity, cabin temperature and humidity, and vehicle AC vent temperature and humidity. Connects to the AC909 via Bluetooth.

Used for weighing refrigerant tanks and equipped with a dedicated solenoid valve for automatic refrigerant charging control.
