The owner at A STAR Air Conditioning is extremely attentive to his business. The only reason I gave them a four is because the employee who was here last time forgot a few things, but the owner reminded him. I'm very happy with the service. I've been using them to clean my unit for several years and I just had them install a completely new AC unit as well. They did a fantastic job. They're honorable, fairly priced, and they do the work in a professional and timely manner. Best of all, they clean up after themselves. They're the fifth or sixth AC service I've used they are by far the best. I would highly recommend them. When you run into quality workmanship like this and service that exceeds the norm by a long shot, it's a pleasure to refer.
