Joe provided an excellent summary of what was wrong with my existing unit and offered reasonable solutions to the problem. Joe was knowledgeable and professional. After deciding on a 3 1/2 ton 14 seer Trane, Raul and his team installed the unit in one day demonstrating their knowledge and skills. It is very impressive that Raul and his team could tear down an existing unit and install a new unit in one day. I was referred to Air and Heat Hospital by my son who wanted the best for his mother and I got the best!
