12/30/25 - Completed a light heating maintenance on four RTU’s. The filters were changed and proper operation was tested. All units were running well and in good condition, except for RTU 1, which is the Daikin unit. The blower motor was extremely loud upon arrival. After checking, the blower motor pulley is completely loose, and the belt was no longer attached to the wheel. The blower motor was also overheating.
