Barrus Heating And Air came out to repair the air conditioning in one of my rental properties. The first time they came out, the serviceman put coolant in my HVAC, and it worked well for about two weeks. When it quit cooling the second time, a different serviceman came out and said the ductwork was the problem and he put a board up to hold it in place. The third time it quit cooling, the serviceman came out and said it was still a problem with the ductwork, did the repair and so far, it is still cooling. I wish they had found all the problems with the first visit. It would have been less frustrating and probably cost less. I called at one point and spoke with the manager who was very nice and helpful. I will not be using them again.
