Get a Free QuoteTotal timeline: 6-14 weeks from first call to rebate check. The process: call NHSaves (day 1), get contractor quotes (1-3 weeks), installation (2-6 weeks wait + 1-3 days work), contractor submits paperwork (1-2 weeks), NHSaves processes (2-4 weeks). You must use a NHSaves network contractor — no exceptions.
Here is exactly what happens at each stage and how long each step takes.
Start by contacting NHSaves to confirm you are eligible for the heat pump rebate program. You can call 1-866-700-6474 or visit nhsaves.com. They will confirm your utility participates (Eversource, Liberty, Unitil, or NHEC) and explain the two rebate tiers.
Pro tip: Call in spring or fall for shortest wait times. Winter is peak season for heat pump installations in NH, and contractor availability is tightest November-February.
You must use a contractor from the NHSaves qualified network. These contractors are trained on the rebate paperwork, approved refrigerant requirements, and eligible equipment models. Get 2-3 quotes to compare.
Pro tip: If a contractor says "any heat pump qualifies," that is wrong. Only ENERGY STAR Cold Climate certified units with R-32 or R-454B refrigerant are eligible. R-410A is banned from the NHSaves program.
If you are applying for the Enhanced tier ($1,250/ton — electric resistance replacement), NHSaves requires pre-verification before installation. An auditor or the contractor will document your existing electric baseboard or wall unit heating system. This step is NOT required for the Standard tier.
Pro tip: Schedule the pre-verification at the same time as your contractor site visit to save a week. Some contractors can handle both in one appointment.
The actual installation takes 1-3 days depending on the system type. However, the scheduling wait — the time between signing a contract and the installation date — can add 2-6 weeks, especially during peak season (fall/early winter). Plan for the scheduling delay.
Pro tip: Book your installation for spring or early summer. Contractors are less busy, scheduling is faster, and you will have the system running before the next heating season. Waiting until fall means you are competing with every other NH homeowner who wants heat before December.
After installation is complete and the system is operational, your contractor submits the rebate application to NHSaves on your behalf. This includes proof of installation, equipment specifications, and confirmation that the system meets program requirements.
Pro tip: Confirm with your contractor that they have submitted the paperwork. A simple follow-up email or call 5-7 business days after installation is reasonable. If they have not submitted, ask when they will. Late submissions delay your rebate.
NHSaves reviews the rebate application, verifies the equipment meets program requirements, and processes the payment. Processing time is typically 2-4 weeks but can extend to 6 weeks during peak periods (December-February).
Pro tip: If you have not received your rebate check 6 weeks after installation, call NHSaves at 1-866-700-6474 and ask for the status. Have your utility account number and contractor name ready.
Your rebate arrives as a check by mail or, in some cases, as a credit on your utility bill. The amount depends on your tier and system tonnage.
Pro tip: The NHSaves rebate is taxable income on your federal return (but NH has no state income tax). For a $1,250 standard rebate at a 22% marginal rate, that is about $275 in additional federal tax. Plan accordingly.
The season you install dramatically affects your total timeline.
| Season | Install Wait | Processing | Total | Rating | Notes |
|---|---|---|---|---|---|
| Spring (Mar-May) | 2-3 weeks | 2-3 weeks | 6-8 weeks | Best | Lowest demand. Contractors are available. NHSaves processing is fastest. |
| Summer (Jun-Aug) | 2-4 weeks | 2-3 weeks | 7-10 weeks | Good | Moderate demand. Good availability. System will be ready for fall. |
| Fall (Sep-Nov) | 3-5 weeks | 3-4 weeks | 9-12 weeks | Fair | Rising demand. Homeowners rushing to get heat pump before winter. |
| Winter (Dec-Feb) | 4-6 weeks | 4-6 weeks | 10-14 weeks | Slowest | Peak demand. Longest waits. Emergency installations take priority. |
Spring installations offer the shortest timelines, best contractor availability, and ensure your heat pump is running and tested before the next heating season. You will have the system for summer cooling (a bonus) and avoid the fall/winter rush when every NH homeowner realizes they need a heat pump.

Complete these before signing a contract.
From first contact to rebate check, the total timeline is typically 6-14 weeks. The breakdown: 1-3 weeks for contractor quotes, 2-6 weeks scheduling wait + 1-3 days installation, 1-2 weeks for paperwork submission, and 2-4 weeks for NHSaves processing. Spring installations are fastest (6-8 weeks total). Winter installations are slowest (10-14 weeks).
Yes. Only contractors in the NHSaves qualified network can submit rebate applications. If you use an outside contractor — even if the equipment qualifies — the rebate will be denied. Find NHSaves-qualified contractors at nhsaves.com or by calling 1-866-700-6474.
Your rebate will be denied. NHSaves removed R-410A from its Qualified Products List effective 2026 due to its high global warming potential (GWP 2,088). Only heat pumps using R-32 (GWP 675) or R-454B (GWP 466) are eligible. Confirm the refrigerant type in writing before installation.
No. If you skip pre-verification for the Enhanced tier (electric resistance replacement), you will be downgraded to the Standard tier ($250/ton). Pre-verification documents your existing electric baseboard or wall unit heating. It must be completed before the heat pump is installed.
Yes, at the federal level. The NHSaves rebate is considered taxable income on your federal tax return. New Hampshire has no state income tax, so there is no state tax impact. For a $1,250 Standard rebate at a 22% marginal tax rate, you would owe approximately $275 in additional federal tax.
NHSaves allocates rebate funding annually. If the budget is depleted, your rebate may be deferred to the next program year. This is uncommon but possible in high-demand years. Installing in the first half of the year (January-June) reduces this risk. Systems must be installed by December 30, 2026 for the 2026 program year.
No. The NHSaves heat pump rebate application must be submitted by a NHSaves-qualified contractor. Homeowners cannot submit rebate applications directly. The contractor handles all paperwork as part of the installation process.
Call NHSaves at 1-866-700-6474 with your utility account number and contractor name. They can tell you whether the application has been received, is being processed, or has been approved. If it has been more than 6 weeks since installation, a status check is reasonable.
