Enthusiast reviews

Be cooler than all your friends.

E30 M3

"Best product I’ve purchased for my E30 M3 in a LONG time, maybe even the best product I’ve ever purchased for it. Excellent fit and finish, wonderful customer service and support. This kit delivers as advertised, and it oozes meticulous R&D in its details."

Carlos Tejuco
E30 325is

"I'm in Houston and last night after charging it up I went out in 87 degrees and 77% humidity - outlet temp driving was 40 degrees! It works great! Everything in the kit was perfect and it went smoothly."

Lindrel Thompson
E30 M3

"Just opened the E30 M3 kit. What a beautiful kit - parts look like they could be factory original or factory approved retrofits."

Kelly BMW Dealership
E30 325i

"I bought the R134a conversion kit for my convertible, and I just had to come give high recommendations. Not only was their kit really straightforward and included literally everything you need, their instructions are top notch."

Caden Proudfoot
E28 M5

"Never thought my 80s BMW could blow this cold! I now have a 35 year old M5 that blows colder air than new cars, and has given me more excitement for sunny days!"

Matthew Vincent
E30 M3

"I installed the A/C Solutions retrofit kit on my E30 M3 and it is incredible. Installation was straightforward with OEM fitment and looks. The ability to have ice cold air through the vents again allows for plenty of comfortable miles for years to come."

Spencer McGee
E30 325is

"The kit came complete with everything I needed to regain my cold air. Installation was a breeze (especially with complete, easy to follow instructions from the company). Once we got everything in place and charged the system, it felt like ANTARCTICA inside my car!"

Rusty Johnson
E28 535is

"As someone who appreciates a quality product and clean finished look, I couldn’t have been happier with the details."

Jake Crayne
E30 325is

"Everything bolts right up with no modification and replaced all the parts I wanted for a fully functional, updated system"

Aaron Corn
E24 635CSi

"If you think you're just gonna fill your original 1980s R12 system with R134 and hope for the best, don't bother. When it actually gets hot out you will still be sweating. Go with this kit if you want to actually bring your A/C up to modern standards and stay cool in 100ºF+ heat."
