Air sealing and insulation rebates

By improving the air sealing and insulation in your home, you can save on your heating and cooling costs all year long. The air sealing and insulation rebates provided by Minnesota Energy Resources help customers with natural gas heating improve the air sealing and insulation in an existing home. New homes, defined as built in the last two years, are not eligible for this program. Homes that participated in the Home Energy Excellence program may not participate in this program.

Please note:

All air sealing and insulation work must be completed by one of our authorized insulation contractors to qualify for a rebate from Minnesota Energy Resources. Our Authorized Insulation Contractor program ensures that you are using a qualified and reputable company. All rebates are issued to customers as a check directly from Minnesota Energy Resources.

Any contractor who claims that they are including a rebate in their reduced cost or is offering a discount if you sign up today because 'they are in the neighborhood' is not doing so through Minnesota Energy Resources.

Minnesota Energy Resources monitors contractors from this list based on an ongoing quality control program. Please check this list prior to selecting a contractor to do the work.
