Delivering safe, clean and reliable natural gas to Minnesota

ENERGY STAR® windows

Upgrading to ENERGY STAR V7 certified windows can save heating and cooling costs all year. Old and inefficient windows can be a huge source of heat loss in your home. If you have natural gas heating in a new or existing home, our rebates can help you improve the comfort of your home and help save money on your heating bill. Qualifying windows will receive rebates and help you save for years to come. You may even qualify for tax credits up to $600.
