Introducing The AC909
Yesterday’s a/c is today’s thermal management system
Coming 2026
From electronically controlled compressors to advanced heat pumps, modern vehicles demand diagnostic tools built for this new era — intelligent, connected, and precise.
- Step by step guided instructions for equipment hookup and the entire repair workflow
- Vehicle-specific overview of A/C specifications and locations, including compressor and refrigerant metering types
- A single screen workflow that incorporates HVAC live pressures and OBD sensor values, including blend door functionality and outlet temperature readings
- First A/C tool that will conclusively identify refrigerant leaks and/or excessive moisture
- Introducing the use of Nitrogen for a pressure leak test “system tightness test” and purge procedures for faster evacuation
- First A/C manifold gauge tool that decouples from the A/C lines while still monitoring low & high pressures
- Variable displacement compressors test by either OBD bidirectional commands and/or physical connection to the ECV valve while comparing live low & high side pressures on a single tool
- Large sight glass allows for visual inspection for excessive UV dye, oil contaminants, component failures caused by heat, and solid particulates
- Self-diagnostics to determine equipment efficiency, tightness, and accuracy
A Glimpse Into What’s Next for Autel MaxiHVAC
Autel redefined vehicle diagnostics—and now we’re transforming A/C and Thermal Management diagnostics and service.
The AC909 is just the beginning of a smarter, more connected future for climate control diagnostics. Harnessing Autel’s “Graphic Diagnostic Diagram” for displaying essential data from multiple modules, coupled with actual HVAC system pressures and temperatures can now be viewed on a single screen.
Our revolutionary repair process gives a technician the ability to quickly and accurately diagnose the HVAC system at a single glance. This diagnostic sensor fusion approach within a graphic diagram can only be achieved utilizing modular test equipment.
The modular Autel MaxiHVAC design takes a new, innovative approach to an outdated industry standard. Each individual component meets the highest standards of quality and serviceability. This modular architecture also delivers greater operational flexibility, enabling technicians to use separate MaxiHVAC components across multiple vehicles simultaneously for increased efficiency and throughput.
Autel MaxiHVAC is uniting these elements into a purpose-built cart designed to organize, protect, and power every component of the MaxiHVAC system. It’s a vision of smarter workflow, premium component quality, and unmatched versatility—because Autel believes advanced diagnostics should empower technicians, not limit them.
