Heating, Cooling & Comfort Measures

For Alliant Energy residential customers in Minnesota

If it's time to install a new heating or cooling unit in your home, it makes sense to invest in an energy-efficient system. It also makes sense to ask your dealer about cash incentives from Alliant Energy-Interstate Power and Light.

Alliant Energy-IPL has great incentives on central air conditioners, clock programmable thermostats, water heaters, insulation, natural gas furnaces and geothermal heat pumps that meet minimum energy-efficiency standards.
