Replacement and new evaporative cooling equipment must have a minimum Industry Standard Rating of 2500 CFM. Premium evaporative equipment must be an indirect/direct, or single-inlet direct evaporative system that delivers cooling through a whole-house distribution system. For the purposes of the program, a whole-house distribution system will be defined as a ducted system with a point of delivery, or register, in each occupied room within a dwelling. Customers installing a new whole-house distribution system with a non-premium evaporative cooler will qualify under the New Evaporative equipment incentive tier.
