DCM6: A/C maintenance complete, Replaced (4) 20x20x1 filters and washed all others. Replaced (2) 10mfd capacitors and replaced 3 phase disconnect. After replacing disconnect and turning system on a/c mode, compressor sounded like the bearings were beginning to fail, then system lost high voltage found that breakers were tripped, reset breakers and turned system on breakers did not continue to trip however compressors are not pumping refrigerant. Need to replace both compressors. Due to equipment being out of warranty and cost of repairs, recommend thinking about upgrading system.
