We've lived in this house for over thirty years so I've dealt with a lot of different air conditioning companies over the years. This time, we hired A STAR Air Conditioning for a repair and ended up hiring them to install a new unit for us upstairs. I am very pleased with their work. Everything was excellent. I was impressed that they installed a drip pan under the unit which is especially important in an upstairs unit. Other companies have never done that and I've had the upstairs unit replaced three times now. It seems like here in South Florida we're always in need of air conditioning service and the slightest leak is not a good thing in an upstairs unit. A STAR was easy to reach and sent someone out right away when I called. The technician called when he was on his way, which I always appreciate, and he arrived right on time. We will absolutely use A STAR Air Conditioning again. Their work was very professional.
