In partnership with local utilities, we are thrilled to offer the DoubleGreen PLUS Loan for those with a yearly household income of $140,000 or less. Ranging from $25,001 to $50,000, this interest-free loan pays for measures that make your home more energy-efficient and safe. In fact, you can get a DoubleGreen PLUS loan for a variety of upgrades (usually as a package of measures), including:
- Wall insulation and replacement windows
- Duct sealing
- Removal of knob-and-tube wiring
- High-efficiency heating and cooling equipment
- Any other measure that the utilities have deemed eligible for the program. A full list can be found here. (Note: the link was wrong, so use the updated link)
Designed to serve the needs of low-to-middle income homeowners with less-than-perfect credit, the loan is paid back in monthly installments. And because you don’t have to pay interest, the loan is extremely affordable.
