Today I arrived to do a ac maintenance on Renee Giordano. I noticed unit 1 is low in refrigerant which is a R22 unit MFD 2003. I advise she speak with comfort advisor about replacing unit because the refrigerant is obsolete. I noticed both units need cleaned and Safeties. Unit 2 was okay everything was good. Office needs to call club member to set up appointment with comfort advisor.
