Performed Platinum Comfort Club Membership Tune-Up on Heating System. Performed maintenance on (4) 2009 Carrier Affinty split systems, and (1) mini split system with (1) head unit to cool server room. Note: systems use 55/6 capacitors for outdoor units, w/ 24x24x4 filters being used in a 5” wide filter casing if that size is more attainable. Systems are marked by number on filter slots, with system #4 having a flooded inducer caused by plugged drain. Cleared drain/trap/inducer. One system has a Honeywell direct intake steam humidifier. Adjusted Cozy plan from 1system to 5systems.
