A second technician arrived to help complete the multiple repairs at this site in Riverside CA. All units needed their evaporator and condenser coils chemically cleaned and the weather stripping on their filter doors replaced. The technicians completed the following: New economizer screens on RTU#2, replacing the crankcase heaters on units #3, #4 and #5, and compressor contactors on units #1, #2, #3 and #4. After completing all approved work, the technician checked out with EMS to confirm no units were in alarm and the site was comfortable. Job complete.
