Came out today to perform one system HVAC home care inspection. Arrival customer stated everything has been working properly and he has had no issues. Upon inspection of the system found that the current filter was the wrong style filter for the system, the UV bulb has gone bad, and the drain line was ran flat across the floor made customer aware that in the summertime this could lead to blockages in the line.. Upon further inspection found the blower will to be clean, cleaned the flame sensor,The indoor coil was clean, all heating elements were working properly. At this time system is up and running properly, and all concerns are in estimates
