Home energy rebates in Lyme, NH
What NHSaves pays in Lyme this year, what these houses actually need first, and how to hire a contractor who can claim it.
Lyme at a glance

What Lyme houses need
Owners of significant old houses in Lyme are often, reasonably, cautious about retrofits — and the caution is sometimes applied to the wrong measures. Attic air sealing and insulation, rim joist work and basement insulation are invisible from the street and reversible, and they carry the entire 75% rebate. Exterior dense-pack, replacement windows and visible line sets deserve the scrutiny; the attic does not.
Local detail worth knowing
Lyme’s river-meadow houses sit low and cold, and its hill houses take wind. Those are different problems: the meadow houses usually need foundation and rim joist work, the hill houses need wind-washing addressed in the attic and better air sealing on the windward side. A blower-door audit distinguishes them in an afternoon.

Lyme rebate questions
What home energy rebates can I get in Lyme?
Lyme is in Grafton County, NH, so your rebates come from NHSaves: 75% of the cost of air sealing and insulation to a cap generally between $6,000 and $8,000, a $100 home energy assessment, and $250–$1,250 per ton on heat pumps to a maximum of $6,250 for households leaving electric resistance heat.
Who does free weatherization in Lyme?
Income-qualified households in Lyme access free weatherization — 100% of the cost, not 75% — through Tri-County Community Action Program, the Community Action Agency for Grafton County. Receiving fuel assistance is usually enough to establish eligibility. There is generally a waiting list, so it is worth applying well before the heating season rather than during it.
Do I have to use a New Hampshire contractor?
You have to use a contractor enrolled in the program, which in practice means an NHSaves participating contractor. Plenty of them are based on the Vermont side and hold both credentials — what matters is the enrollment, not the address on the truck. We check this before we introduce anyone.
Is a heat pump worth it in Lyme?
For most houses here, yes — particularly if you are currently on electric resistance heat, propane, or oil, and especially once the envelope has been tightened. ENERGY STAR Cold Climate equipment produces heat well below 0°F, and most local designs keep a backup for the coldest nights. The cooling you get in July is increasingly not a side benefit.
