Advanced A/C Diagnostics The Autel MaxiHVAC AC909D is an advanced A/C and thermal management diagnostic system for precise, data-driven A/C service. The system includes the AC909 tablet, MaxiFlash VCI, refrigerant scale, compressor box, NAVAC® Bluetooth vacuum pump, digital micron gauge, 4-port manifold with large backlit sight glass, Bluetooth temperature and humidity probes, and Bluetooth temperature clamps. Additional included items consist of a nitrogen regulator, refrigerant hose, vacuum hose, 45° and 90° fittings, A/C hose 1/4″ gaskets, vacuum pump 3/8″ hose gaskets, red/blue R134a service couplings, red/blue R1234yf service couplings, and R134a and R1234yf adapters. Live micron-level vacuum measurements stream directly to the AC909 tablet, enabling technicians to verify moisture removal and perform automated decay testing rather than relying on evacuation time alone. The AC909D combines refrigerant data with live vehicle diagnostics, airflow, temperature, electrical, and sensor information for complete thermal management system visibility. 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, while dedicated diagnostics support 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 AC909D helps reduce guesswork, avoid unnecessary repairs, and improve first-time fix confidence. Includes one year of software updates and a one-year limited warranty; NAVAC® vacuum pump includes a two-year warranty .

But today’s vehicles are built around intelligent thermal management. 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. 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. By identifying the root cause before refrigerant is removed or components are replaced, technicians can reduce guesswork, avoid unnecessary repairs, and confidently verify every repair before returning the vehicle to the customer. Live Micron-Level Data Vacuum Becomes Diagnostic Data The included Bluetooth-enabled NAVAC® Smart Vacuum Pump and digital micron gauge stream live measurements directly into the AC909 tablet and workflow, allowing technicians to verify moisture removal rather than rely on evacuation time alone. Live micron readings and automated decay testing turn vacuum into measurable diagnostic data, creating a more precise, documented evacuation process based on proven commercial HVAC practices. Combine live refrigerant pressures, temperatures, humidity, and system measurements into a single graphical analysis screen, while connecting leak testing, refrigerant service, and vehicle diagnostics in one guided workflow. Gain a complete view of the vehicle’s thermal management system to reduce guesswork and improve first-time fix rates. Ready to Upgrade Your Diagnostics? Contact our scan tool experts today.
