Upon arrival we noticed the 3/5 outdoor units were extremely caked with cotton wood debris. We brought this to managements attention and they went ahead with the chemical cleaning on those three units. We then preformed cooling maintenance on all of the units. We tested start and run amps on all outdoor electrical components and found that 1(trane) unit was starting on the high side. All other electrical components on each of the systems tested within manufacture specifications. We tested electrical components on each inside unit all tested within manufacture specifications. We treated drain lines with total c to help prevent clogs. We did notice one of the emergency drain pans had some rust build up in the bottom. Which could potentially lead to a leak in the ceiling if the unit were to get clogged and go into that drain pan. Temperature splits on all the units were within 18- 20 degrees. Units were cooling upon departure. 521 ELECTRONIC HARD START 189-227 UF 170-277V 1 HP AND
