Air-source heat pump

An air-source heat pump is an efficient way to heat and cool your home without the use of natural gas. When heating your home, it takes heat from the air outside and transfers it inside by using refrigerant. It cools your home by doing the same thing, but in reverse. You can find more information about air-source heat pumps at the Department of Energy. We offer rebates for air-source heat pumps up to $800.

Rebate requirements:

  • Alliant Energy must provide the electricity for the equipment installed
  • Units must be less than 65,000 BTUH
  • Minimum efficiencies: SEER 15/EER 12.5/HSPF 8.5
  • Condenser and coil must both be replaced
  • Qualifying unit must be shown in the current AHRI directory


The age of your home will determine your rebate. 

  • Homes five years or older are considered existing homes.
  • Homes less than five years old are considered new homes.

What is SEER?
Seasonal Energy Efficiency Ratio (SEER) is a measure of the cooling efficiency of the unit based on an average summer temperature. A higher SEER value indicates a more efficient unit.

What is EER?
Energy Efficiency Ratio (EER) is a measure of the unit’s efficiency. It isn’t calculated with seasonal temperatures, but with constant outside and inside temperatures.

What is HSPF?
Heating Seasonal Performance Factor (HSPF) measures the heating efficiency of a heat pump. A higher HSPF value indicates a more efficient unit.
