A guaranteed way to ensure quality installation, rebate 

eligibility and energy savings! 


There are new requirements for air sealing and insulation rebates.  All air sealing 

and insulation work must be completed by an Authorized Insulation Contractor of 

Minnesota Energy Resources. 


This seal ensures that a contractor follows the new requirements. 


Sealing and insulating a home is a great way to save on heating and cooling costs. 

And, with rebates of up to $650, even more can be earned. Recently, Minnesota 

Energy Resources has established a group of Authorized Insulation Contractors who: 


   • Agree to the program requirements and high quality standards. 

   • Received national BPI Installer certification.
   • Agree to quality assurance inspections.
   • Follow safety protocols to protect families. 


All air sealing and insulation work MUST be done by contractors participating in the 

Authorized Insulation Contractor Program in order to qualify for a rebate.
