I agreed to purchase an AC system from this company. They agreed to install a certain brand, quality and size unit. They also made multiple guarantees in their advertising and sales presentation. When they installed the equipment, it was the wrong brand and in the wrong location of the HVAC closet. They would not honor any of their guarantees they had advertised or promised in their sales presentation. This has been a $10,000 mistake. The system never worked as promised. Be careful. Their ads are slick. They go under multiple names Hobson Air Conditioning Inc and Comfort Experts Inc. Do your homework. In my experience they are much better at marketing than servicing their customers or keeping their promises. In my case the guarantees were worthless. Do your home work.I thought I had and I was taken hard.
