No AC!! Called CSI and they were here in 30 minutes. Not only did they get us back up and running, they took the time to explain why our unit was not working, and explained what we could do in order to prevent it from happening again. Had the parts on his truck, and we were cool in an hour. Can’t get any better than that. Also, the owner stopped back by a few day’s later just to check to make sure we were happy. My wife and I both appreciate the quick and honest service. We will continue to use SI due to our experience we had with them. Great Job!
