Performed a tune-up and safety check-up for a AC unit. Client stated no issues. We found a weakened blower capacitor, right at 7.5 actual reading was 6.5. Client also found a weakened condenser capacitor for the fan which read 2.7 however the ratings were faded on the fuel capacitor. AC system seem to be slightly low on r22 refrigerant, Client opted not to get anything replaced at this time because he plans on replacing both furnace and AC unit in the near future. After cleaning the outside coil Delta tea went from a 15 to an 18. System is operating and cooling the house.
