Performing AC maintenance on 2 systems, both 1998 Bryant condensers, for one of our certified members in Los Altos Hills. Cleaned up and tested refrigerant levels, inspected and tested safety and electrical components and made recommendations as needed. One system is struggling at this time, compressor motor is making a loud noise and pressures are fluctuating indicating that there may be noncondensibles in the refrigerant lines - no filter line drier in place.
