Bartle was hired for my cool air system, i'd rate them a 4/5, -1 pt for the confusion and the delay that they caused, when they finally did arrive 2 weeks late they did their job correctly and got everything working, but they seem to be disorganized at that time, so i don't think i would go back to them again, they kept putting our installation date off causing us confusion and having to cancel work, although all the delays were annoying, they did have friendly staff and apologized each time they were delayed, and they did do the job perfect which is the main and important thing.
