Columbia Water & Light - Residential HVAC Rebates

Quick Summary

If your air conditioning or heat pump system is over 10 years old or causing rising utility bills, you can receive a rebate of $800–$1,200 depending on the efficiency rating (SEER2) of your new unit, with geothermal units under 5 tons receiving $1,200. To qualify, you must be a Columbia Water & Light electric customer replacing an existing system (not new construction); submit your rebate application with a paid receipt, model numbers, and a copy of the final mechanical permit within six months of installation on a first-come, first-served basis. Heat pump customers also qualify for reduced electric rates from October through May, and additional electrification rebates are available when replacing both an air conditioner and gas furnace with a qualifying heat pump.
