I arrived to a diagnostic service call. Upon arrival I discovered filter needs changed. Dead cap/replaced. Washed unit. Compressor-7.6 rated 14.7. Fan-1.4 rated 1.3 over amping and sounds terrible, will fail soon. Condenser coil is literally starting to crumble. Refrigerant levels:73/246 20SH and dropping. 21yrs old system is at the end of its life. All good for the time being.
