Found primary float switch tripping intermittently upon arrival. Auxiliary drain pan, float switches, and primary drain trap were recently replaced by another company. Trap used was not deep enough, and not vented causing drainage challenges. Installed EZ trap and vent, and insulated 5’ of primary drain line in attic due to sweating. Tested drainage with no further challenges. Also found auxiliary pan with small amount of water present due to drip tray underneath evaporator coil fallen alongside primary drain issues. Re-secured with self tapping screw to bracket through service panel. Customer stated they will remove excess water from pan with shop vac. Stated (2) rooms seem to stay hotter in summer months, and colder during winter months. Both 6” flex lines for these rooms are crushed and need replacement. (2) 6” lines approximately 10’ long each totaling 20’. Also recommend re-insulating trunk line plenum exiting air handler due to sweating. Built and sent over estimate for repairs.
