I hired Hanson to put in a self contained air conditioning and heating unit. The name of the unit is Heil. Hanson will rip you off, he doesn't do what he is supposed to do, he will take your money and run. What I mean is he was supposed to give me a certificate of insurance and paperwork of warranty which he didn't do. Also I added another room and told them to come back and do the other room, he put small pipe in and it doesn't heat or cool the room the way its supposed to. He will tell you he will do lots of things. He told me that he would take my old heating and cooling unit out of my double wide and make me a nice closet out of it. Hanson Heating and air is a thief, he will take your money. I advise anyone not to hire Hanson for anything cause he will rip you off the same way he did me.
