How It Helps You

Adding or upgrading insulation can cut heating and cooling costs by 10-30% depending on your home’s current setup and climate. You’ll enjoy a more consistent indoor temperature – warmer winters and cooler summers – with fewer drafts. This utility rebate stacks nicely with federal incentives like the Inflation Reduction Act’s energy-efficient home improvement credit (up to 30% or $1,200 annually for insulation). Environmentally, better insulation reduces energy use and lowers your home’s carbon footprint. Pros: Substantial upfront cash back, long-term bill savings, improved comfort. Cons: Requires a licensed contractor, some paperwork, and eligibility limited to electric-heated homes in MN.
