What began as an afternoon in the garage to fix the leaking compressor in the M5, quickly snowballed into many overnight parts orders, lots of trips the machine shop, and a dangerous coffee addiction to figure out how to properly (and reliably) retrofit the E28 HVAC system to R134a using a modern Sanden compressor. After many weeks of development, countless hours in AutoCAD, and a whole bunch of wasted hoses, brackets, and freon, the first prototype was ready for testing...then another one...and so on. With summer right around the corner, and a functioning system underway, the next step was adjusting the bractetry, hardware, and overall layout to match BMW's design language of the 80s. This included sourcing factory-like components from the correct metric lock nuts to the original corrugated heat shielding and building a user guide that closely followed the well known Bentley service manual.

Fast-forwarding to today, with hundreds of satisfied enthusiasts using our products, we have become the first and only company to offer a true plug-and-play Sanden conversion for the E28 and E24. A/C Solutions started out to solve a simple problem and, thanks to your feedback and involvement, has been able to successfully support the vintage BMW community to provide reliably cold A/C despite weather conditions.
