Upon my arrival, in Rosanky, for an AC evaluation, I completed the heating evaluation of both systems. While onsite I flushed and treated the drains within the attic, I tested all heating operations and verified systems are safe and performing at this time. I did mention the systems age and the thought of replacement due to age and the signs of oil in drain pan indicating an indoor refrigerant leak on unit number 2 which services the master side of the home. At this time customers are going to wait on replacement until they notice a difference in performance this summer. Upon completion I left both units running schedule for heat set at 65.
