Their customer service has been great. I'm very happy with Family Air LLC. We have a good relationship. They've done work for me both commercially and also on our own home. They just installed a residential two and a half ton unit in our home a year ago. It was a great experience. Their follow-up has been excellent. They came out two weeks ago for the one-year anniversary check. I didn't even know when the one-year anniversary was, and they showed up without me having to ask. Their customer service is fantastic. My wife and I also run a large resort in Tucson. I have over a hundred air conditioning units and replace as many as three or four each year. They just installed a commercial two and a half ton unit for the kitchen and also a seven ton unit. I highly recommend them.
