What we see in Nashua homes
The typical Nashua home was built between 1950 and 1980, which usually means R-11 fiberglass batts in the walls, a thin layer of batts on the attic floor, no air sealing anywhere, and a rim joist that was never insulated. Ranches, split-levels and garrison colonials from these decades are the bread and butter of our NHSaves work: air seal and top up the attic, foam the rim joist, and the house feels like a different place.
Roughly 73% of owner-occupied homes in Nashua heat with natural gas, so for most households the NHSaves rebate is run by the gas utility rather than the electric one. Gas is cheaper than oil, but a leaky house still wastes a third of it, and the program's rebates are the same.
Housing figures: U.S. Census Bureau, American Community Survey 2020 to 2024 five-year estimates for Nashua; heating fuel shares are for owner-occupied homes.
NHSaves rebates in Nashua
Most of Nashua is served by Eversource for electricity and Liberty for natural gas. All of them are NHSaves utilities. If you heat with natural gas your Home Energy Performance rebate comes through Liberty; if you heat with anything else it comes through Eversource.
On most Home Energy Performance projects the program pays 100% of air sealing and 75% of insulation, up to $6,000 per home, and your share can go on a 0% or 2% program loan. We assess the house, model it, file with the utility and take the rebate off the invoice. How the program works.
Many Nashua households also qualify for the program’s income-eligible side. Households at or below 60% of the state median income get the work covered in full through NHSaves Home Energy Assistance, and Eversource customers up to the state median income can get an enhanced no-cost package. Tell us roughly what the household earns and we will point you to the right program; nothing is filed without your say-so.

Questions from Nashua homeowners
How much does insulation cost in Nashua, NH?
It depends on the house, but for a typical Nashua home the NHSaves program pays 100% of the air sealing and 75% of the insulation, up to $6,000, so most homeowners pay a quarter of the insulation cost and nothing for the air sealing. We give you the exact figure in writing after the assessment, and 0% or 2% financing is available for your share.

Which utility runs the NHSaves rebate in Nashua?
