Complete System Replacements: Central Air Conditioning (CAC) units do not have a qualifying products list. The CAC with both the evaporator coil and condensor unit, must be rated at 14.5 SEER or greater and be AHRI Certified. Visit www.ahridirectory.org to verify certification.
Please Note: The current ENERGY STAR rating for boilers and furnaces includes an efficiency range that may be lower than the Nicor Gas Energy Efficiency Program's efficiency levels, which would make these products ineligible for rebates under the Nicor Gas program. Please be sure to check the efficiency level requirements on the Rebate Information page prior to purchasing a product.
