Cold-Climate Heat Pumps, Built for New Hampshire Winters

The two time periods are stated separately because they are different facts.
Published equipment range
Selected GREE equipment operates down to -22°F
That figure comes from the published operating range for specific equipment Dave installs. It is not a promise that every system or every house performs the same way.
One house, several good paths
What Dave installs
The right system depends on the rooms, the ductwork, the emitters and the winter load.
The arithmetic competitors leave out
See incentives and a fuel-saving range before you book
Mode 1 uses your house and fuel inputs to show the two NHSaves tiers separately, a provisional rebate range and a range of annual fuel savings. It never invents an installed price.

What New Hampshire still pays
Each figure keeps its eligibility conditions beside it.
NHSaves standard tier, per ton
Paid per ton of installed nominal heating capacity on qualifying equipment. Tonnage is set by the installed equipment and by a load calculation, not by floor area. Available through a participating New Hampshire electric utility account.
NHSaves electric-resistance replacement tier, per ton
Applies only where the heat pump replaces existing electric resistance heat. The amount is the 250 per ton standard rebate plus a 1,750 per ton additional rebate. The additional 1,750 per ton tier requires pre-verification with NHSaves before installation. Homes heated with oil or propane qualify for the 250 per ton standard tier instead.
NEHPA instant discount, per qualifying outdoor unit
Up to 750 dollars per qualifying outdoor unit, applied as an instant point of sale discount. One multi zone outdoor unit can serve many indoor heads and still counts as one unit. The exact amount depends on the specific model and its position on the qualified products list. New construction is not eligible.
Air-to-air and air-to-water solve different houses
An educational comparison, not a house-specific design
Air-to-air
- Moves heat through indoor air
- Works with ductless heads or ductwork
- Provides heating and cooling
Air-to-water
- Moves heat into a water loop
- Can serve compatible radiant or hydronic emitters
- Needs a house-specific system design
Selection criteria, not a scripted method
How equipment gets chosen
Dave weighs the conditions that determine whether a system will still make sense in January.
Winter capacity
Published low-temperature performance matters more than a warm-weather headline number.
House heat loss
A Manual J load calculation, not floor area alone, determines the real heating requirement.
Distribution
Existing ductwork, room layout and hydronic emitters shape which system path fits.
Backup heat
The existing boiler may still have a useful role on the coldest days or in hard-to-serve zones.
Real client work
Real work, real rooms
Every photograph here is Dave's own job, supplied by him. Nothing on this band is generated.
Mechanical rooms, built to be serviced
Cascading boilers, tanks and manifolds set out so the next person can actually work on them.
Placement gets decided on site
Where the units sit changes how they run, and that call is made standing in front of the house.
Clean lineset routing, kept orderly
The bracket and protected run are the finish details that stay visible for years.
In a customer's own words
“He only performed top-notch work, kept every commitment, was timely and never left a mess.”
Over the course of this last summer, we had him back to replace another failing single-zone unit, and then to complete a 2-zone system; all GREE product.
A north-to-south service corridor
Salem to Coös County
The first demo set covers six New Hampshire towns across the corridor.

NH Heat Pump Incentives in 2026: What Is Still Available
New Hampshire still pays through NHSaves and the New England Heat Pump Accelerator. The federal 25C credit ended December 31, 2025, with no grandfather.
What Changes a Heat Pump Project Cost in New Hampshire
Heat loss, zone count, distribution, electrical work and access move the price far more than floor area does. Two same-sized homes need different systems.
Do Heat Pumps Work in a New Hampshire Winter?
Yes, when the model's published low-temperature capacity is matched to the building's measured heat loss. An operating limit alone is not a heating promise.
