I worked on units 5,6, and 7. These units are not running as they should be due to lack of maintenance. I deep cleaned each condenser coil inside and out to get as much dirt and cottonwood out of them. Also all condensation drain are clogged. I cleared them and refilled the j traps. Changed the filters in each unit which had not been done for over a year. This area is for the shop and needs to have the fliters change at least every 3 months if not sooner. After that all system had a good temperature split. This all can be kept up with if they can get a PM set up so we are not spending hours to clean and common house keeping on all the units for this location.
