I don't know where to start. Thanks to Brian Sr and Jr and thier helpers they helped my almost 30 year old ac limp along for the past few months. Today they put in my new unit. I had a 3.5 ton unit now I have a 4 ton unit. For my 1500+SF home. They are prompt, honest and reliable. I even left my house key with them when I could not be home. Within an hour of the new unit being turned on my house was once again a cool haven from the desert heat.
