COOL SMART continues to provide a Right Sizing Incentive of $150 per 1/2 ton of downsizing to the contractor and $150 per 1/2 ton of downsizing to the customer for replacement systems. The system must be sized to match ASHRAE manual J sizing - or sized to match the measured system air flow of the existing ductwork. Pre-approval is needed when the new system to be installed is 3 tons or greater. Contact Charlie McCracken at (508) 328-0946 for pre-approval.
