Recently, sadly as weather got really warm, one unit continued to pump air but it wasn't cool. It provided A/C for second-floor bedrooms.
I submitted an on-line service request and Debra from the office called me. She scheduled a technician for the same day. John W arrived right on time, quickly and thoroughly checked all parts of the system, and discovered there was apparently a fluid nitrogen leak. He will confirm and schedule a return visit. John was very efficient and patient in explaining things to me the non-technician. CWJ
