8/25/25 - Completed a full cooling maintenance on all RTU’s. The filters were changed, the coils were washed, and proper operation was tested. Unit 1 has condenser fan bearings that are starting to show wear, it is still running fine at this time, but it will need to be replaced soon. Then, units 5 and 6 each have a discolored 2 pole contactor for the compressor, they are still functioning fine at this time, but they may also need to be replaced soon. Other than that, there were no other issues found at this time, all the units were running well, and they were all in good condition. The hot water was flushed, the expansion tank was checked and the circulation pump was checked.
