I never really weigh them, but i would say they avg around 15 lbs after you clean them. Largest evaporator coil i got was over 15lbs per side, So 30lbs would be the heavyest ive seen. Usually the evapo coils dont weight that much unless your getting it out of a older or big hvac system witch is very unlikely for residential. The biggest one i got was from a loft and the furnace had 2 blowers in it. It was freaking huge.
