When your John Deere tractor's A/C system starts blowing warm air — or stops working altogether — the answer isn't a new machine. Our fitment-specific John Deere A/C Conversion Kits replace outdated A6 and Denso compressors with modern Sanden-style rotary units that run cooler, draw less power, and are fully compatible with today's R134a refrigerant standard. From classic 4230 row-crop tractors to large-frame 4840s, each kit is sourced from AP Air and includes everything needed for a complete installation — compressor, receiver drier, expansion valve, and O-rings — so you can restore factory-quality A/C at a fraction of the cost of new iron.
