To qualify for the AEP mail-in cash rebate, homeowners need to install a 15 SEER air conditioner or 15 SEER & 8.5 HSPF heat pump. AEP's rebate structure is as follows: $300 for heat pump systems that qualify; $150 for qualifying air conditioners. Adding a qualifying smart thermostat can bring the maximum all-electric rebate possible to $400. For traditional gas furnace & AC homes the maximum – with qualifying smart thermostat – is now $200. If you have any questions on the new rebate structure and/or would like a free in home estimate, feel free to contact our sales staff at 614-784-9200. Hetter is proud to be a part of this program.
