Brad has explained that his main floor Ac system has been making a loud noise, not cooling properly, and the fan on top is not turning. Upon diagnostic of the 18 year old system I found the capacitor has failed. This must be replaced before further diagnostics can be performed. After installing the capacitor and getting the unit running I performed the rest of the diagnostic. I found the unit is low on refrigerant. The compressor amperage is within manufacturers specifications but the fan is over amperage. I have recharged both Ac units and added sealant. Both are running well at this time and Brad is happy with today’s service. *** Should the unit’s become low on refrigerant again, further leak testing will be required***
