June 4, 2013 To Whom It May Concern: Trey Medlin has just installed a ductless split system air conditioning unit in my house. I am totally impressed with the Fujitsu wall mounted heat pump system that he installed. This system is a proficient heating and cooling unit individually controlling the four zones in the house. I'm sure this energy efficient product will economize usage for both heating and cooling and provide cost effective. results. Trey Medlin of Medlin Mechanical did an outstanding job with this accomplishment. His attention to detail was excellent and his workmanship ethic was outstanding. Furthermore, he has an excellent rapport with his customers and fully explains all the technical aspects of the system including installment and overall performance of the unit. He understands the architectural designs of homes and buildings in this area and works to maintain the aesthetic beauty of them by incorporating non-visual techniques in the installment of compressors and other units on the roof. I highly recommend Trey Medlin to anybody who wants to invest in the improvement of their homes. His knowledge and expertise in geothermal heat pumps, solar thermal hot water heaters, high efficient boilers ductless split systems and other energy efficient units is outstanding. Aurelio Roybal
