Client called for a quote to clean the ducts and to perform a AC tune up. Upon Ac inspection and service I tested temperature drop, relative humidity, air flow, motor and fan, compressor, capacitor, contactor, evaporator and condensing coils, and refrigerant. Tech found the capacitor is starting to wear out this is a common wear and tear item, the out door condenser is getting a little dirty and the AC is low on refrigerant this can be due to either a small leak somewhere in the system or proper refrigerant was added on original install. Tech informed client and made options client will discuss it with her husband and get back to us.
