so i was in the supply house yesterday and was told these new locking refigerant caps are code now in florida. even on commercial? also i was told hurricane straps are going from one steel bracket in each corner to two in each corner. and a couple months back they started making us put float switches on the primary drain line and a float in the pan. this seems to be getting out of control. anyone shed some light here. everytime we install a unit they have something new to ding us on.
