Performing AC tune up on two 1993 Carrier condensers, one of which is not able to keep the upstairs cool on hot days. Inspected and tested system - checked refrigerant levels, compressor and fan motor starting and running amperages, filters, static pressure, blower amperages, circuit boards - after 25 years systems are beginning to show signs of failure. Made recommendations for repairs and cleaned up systems as best as possible.
Performed AC Diagnostic on 1 unit and a Tune Up on the other for the KFO contest winner of the free tune up. One system hadn’t been working for 7 years, previous companies had said it was irreparable. It issue was simple, a low voltage wiring which tells the unit to turn on was improperly wired. Corrected and system runs. Other unit was in good shape. Client was pleased, happy to help out our contest winner
Tune up time. Getting this system cleaner then the day it was installed.
