I had an American Standard Platinum HVAC System installed. Brandon, Stewart, and Preston did the install work. They were scheduled to start at 8:00 am. Stewart arrived at 7:45 am and immediately went to work. Brandon and Preston arrived at 8:00 am with the new HVAC System. I tried to offer them drinks and something to eat but they were more concerned with completing the job. The crew was absolutely fantastic. They completed the install work in about 7 hours. They never stopped working until the job was completely finished. They did an outstanding job installing the new system. The company even filed my warranty paper work for me. I had to do nothing but sit back at let them do all the work, from the install, warranty registration, and setting up the county inspection. They even provided financing for 0% interest rate for 60 months. I would ABSOLUTELY recommend Daimond Air Design for HVAC System Replacement!!!
