I needed to install a new ac unit in my home. I did not do much shopping beforehand, but I knew that Stan's had a solid reputation. They have been in Austin for a long time. The technician that they sent was super friendly. He was knowledgeable and informative. He gave me all the instructions I needed to care for my ac system. It has been working great so far. I was totally satisfied with the service. They are a trustworthy company. I would highly recommend them.
