Heat pump questions
Straight answers before the appointment
Yes, cold-climate heat pumps heat New Hampshire homes through the winter, provided the model's published low-temperature capacity is matched to the building's measured heat loss. No, an oil-heated home does not receive the $2,000 per ton NHSaves tier: that tier is for replacing existing electric resistance heat, so an oil or propane home plans on $250 per ton. Every answer below keeps its conditions attached.
Common questions
Useful answers, with the conditions intact
Do heat pumps work in a New Hampshire winter?
Cold-climate systems are designed for low outdoor temperatures, but equipment selection, load calculation, distribution, and backup planning matter. Dave matches the system to the house instead of treating a product label as the design.
Does an oil-heated home get the $2,000 per ton rebate?
No. The $2,000 per ton NHSaves tier applies when qualifying heat pumps replace existing electric resistance heat and the additional tier is pre-verified. An oil- or propane-heated home generally falls under the $250 per ton standard tier, subject to all program conditions. Last verified 2026-08-01.
Is the federal 25C heat pump credit still available?
The federal 25C energy efficient home improvement credit ended on December 31, 2025. Equipment installed after that date does not qualify, and there is no grandfather provision. Last verified 2026-08-01.
Can a heat pump use my existing ductwork?
Often, but the ductwork has to be measured for airflow, leakage, and capacity. A ducted heat pump can be a strong fit when the existing system can distribute the required air.
Can a heat pump serve radiant floors or hot water?
Air-to-water heat pumps can serve hydronic distribution and domestic hot water in the right design. The water temperatures and heating load determine whether the existing emitters are a fit.
How do I get an exact recommendation?
Book a consultation so Dave can see the house, review the current system, and complete the measurements that an online tool cannot replace.
Dave's Ductless HVAC approach
What an online answer cannot replace
Three checks still happen on site
The website can prepare the conversation without pretending it has inspected the house.
Room-by-room load
Floor area can bracket a system, but the room loads decide the installed capacity.
Program eligibility
The program administrator and qualified equipment list decide the final incentive, not the website.
Distribution and backup
Existing ducts, hydronic emitters, electrical capacity, and the coldest-day plan need to be seen in the house.
