The Louisiana Department of Natural Resources (DNR) manages the Home Energy Loan Program, or HELP, for homeowners making energy efficiency improvements. HELP loans offer a maximum principal of $12,000 to be repaid over five years. Half of the principal is disbursed by the DNR at 2% interest. The other half is disbursed from any of the HELP partner banks at their current market rate. The partner bank will handle all servicing responsibilities. HELP loan partners set their own institutional policies, including their own interest rates and the maximum amount for their own portion of the principal. Interested homeowners should therefore contact their local partner directly to apply or make further inquiries. A list of current HELP loan partners is available from the DNR website.
