Financing Energy-Efficient Home Upgrades with the HERO Program

A-1 Guaranteed is proud to be a contributing member of the HERO Program, a government sponsored incentive program that helps homeowners finance energy-efficient home improvements through Property Assessed Clean Energy legislation, otherwise known as the PACE Program.

The HERO Program allows homeowners to invest in vital energy and water saving home upgrades with low, fixed interest rates. Payments are made through the homeowner’s property taxes. Financing terms range from 5 to 25-year repayment plans. The homeowner may also be eligible for tax-deductible interest payments and/or PG & E rebates. There are no upfront costs attached to the HERO Program. Any upgrades made with the HERO Program will not affect the homeowner’s credit score. Eligibility for the program is based on the current value of the applicant’s property. Homeowners can borrow up to 15% of their home’s current value.
