I brought my 1990 Chevy van back to DKA to have the air conditioning repaired, since they did such a good job with the previous work. They pretty much had to refurbish my entire system, as the van is 25 years old. When I first got the van back I wasn't sure if it was blowing cold enough, but after thoroughly sealing and insulating the cab of the van, it cools down nicely now. I still need to have the windows tinted as well. Overall. It was a good job and I'm satisfied.
