I don't typically leave bad review but this one is exceptionally bad that I have to leave one. This business in Plainview, we bought a house in Lubbock, that has a system installed in Nov 2022 (only 7 months till current date), called them multiple times and every single time was terible and disgusting interaction. The first time the system was not running, Larry, complained and blamed construction company, which might be true. The second time we called because there was not sufficient cooling in part of the house, we called and asked if they could do an estimate, they again blamed construction even though there is no construction anymore. Larry refused to come out to have a look because it is too far and said he would only do it if it we pay him $85/h for 2 hours of driving and how many hours of working. I got other companies took a look and they all agreed that the design was flawed, there is not enough supply and return to that part of the house. Worse, when Quality Air installed it, they got the supply line in a larger duct compared to the return line. Last incident, just yesterday July 2023, only 8 months after the installation, the hvac stopped blowing cold air. We called them, Larry again complained about it might be dust and construction. However, he still did come out. Turned out it was a blown compressor. Larry did not really care to give a quote on replacing the compressor and just said he did this job (install the hvac) for a friend (the previous owner) so he has no obligation any more. He said there is no labor warranty on the system. Again, this is only 7 months after installation. This would be our last interaction with them. The worst thing on all of this is the unprofessionalism, continuing blaming of contruction while it was not true any more and the complains about having to drive too far. We were always courteous when we called yet every time Larry called, it was all about construction causing too much dust, too far away, etc. No professionalism whatsoever. Things go bad, we understand that but the way the conversations were handled was unbelievably bad. I would leave 0 star if i could
