Brennan G Today I visited and preformed the first filter change visit (1/4) and the first maintenance visit (1/2) for all 18 RTUS for the Chapel. I sprayed all of the evaporator coils with cleaner, cleared drain traps. Inspected electrical cabinets and verified all of the major system components are operating normally. I also added screws to many of the RTU panels. Tomorrow I will be returning to replace the belt for RTU#12 , and preforming filter changes/ maintenance for the Hope Center
