We used to have this problem at the Peoria Civic Center Carver Arena. Early in the season and late in the season when the outside temps spike. They did a complete remodel of the HVAC system and added chillers, that can be used at anytime of the year, to bring the temps and mostly the humidity out of the arena. Had a game in the early 90's where visiting Villanova said they would never come back because of the condensation from the hockey ice below.
