Arrived onsite for ac maintenance on 1 system. Asked customer to turn AC on to confirm operation. They mentioned the system had issues keeping up last year. Checked all electrical. Chemically Cleaned outside unit, measured pressures for R22 at 61/110 psi with 3degree sub cooling with outside temperature at 47 degrees. Measured temperature drop at 20 degrees. Cleaned condensate line. Observed rusted evaporator coil. Noticed water stains in the air handler. Observed failed motor seal on blower motor. System has used over 90% of its life. Performed efficiency test utilizing MeasureQuick but could not get stable readings. System running but not well. Discussed with homeowner and they elected to replace the system.
