Performed cooling maintenance on two AC systems. Cleared and treated both drain lines and washed both condenser coils. I found both systems have small amounts of dirt and mold in the blower wheel and around the air handler. I wiped it off as best as I could and offered the customer options to repair; she declined at this time. I also found the filters are dirty, but the customer didn’t have any replacement filters for me to change out today. She said she will replace the filters as soon as she is able to purchase some. No other major issues were found. Both systems are on and running at this time.
