The cooling load calculations must be based on methodology in Air Conditioning Contractors of America (ACCA) Manual J and the mandatory cooling load calculation assumptions provided in the Cool Cash Incentive program manual for participating dealers. Installed equipment is considered properly sized when its Standard Capacity Rating as reported in the current ARi directory of Unitary Equipment is within one-half ton (6,000 Btu/hr) of the calculated cooling load.

To qualify for proper installation incentives, the central air conditioner must be installed according to the requirements provided in the Cool Cash Incentive program manual for participating dealers.
