Question 1

Do heat pumps work in New Hampshire winters?

Accepted Answer

Yes. Modern cold-climate heat pumps — like the Mitsubishi Hyper-Heat systems we install — deliver full heating capacity at 5°F and keep working below -13°F. They're now the primary heat source in thousands of NH homes. For homes with an existing furnace or boiler, we often set up a dual-fuel arrangement where the heat pump handles most of the season and the backup covers the coldest snaps.

Question 2

What rebates are available for heat pumps in NH in 2026?

Accepted Answer

NHSaves currently offers $250 per ton for qualifying cold-climate heat pumps replacing oil, gas, or propane heat, and up to $1,250 per ton when replacing electric resistance heat (that tier requires utility pre-approval before installation). Systems must use newer refrigerants (R-32 or R-454B) to qualify, and the federal 25C tax credit ended December 31, 2025. We handle rebate paperwork with your quote.

Question 3

Heat pump vs. furnace — which is right for my home?

Accepted Answer

If you heat with electric baseboard, oil, or propane, a cold-climate heat pump usually cuts your heating costs substantially and adds air conditioning in the same unit. If you have cheap natural gas, a high-efficiency furnace may still win on pure operating cost, and a dual-fuel setup often makes the most sense. We'll run the numbers for your actual home rather than giving a one-size answer.

Question 4

What size heat pump do I need?

Accepted Answer

Sizing depends on square footage, insulation, air sealing, window quality, and layout — not just square feet. As a very rough NH guide, most homes need 25–35 BTU per square foot, but an oversized unit short-cycles and an undersized one runs constantly. We do a room-by-room load assessment on every quote so the system is sized right the first time.

Question 5

How long does a mini split installation take?

Accepted Answer

Most single-zone installations are done in one day. Multi-zone systems typically take 2–3 days depending on the number of indoor heads and electrical work needed. You'll have heating/cooling in the finished zones the same day they're installed.

Question 6

How often should my HVAC system be serviced?

Accepted Answer

Once a year for most systems — ideally spring for AC/heat pumps and fall for heating equipment. Regular maintenance (clean coils, correct refrigerant charge, fresh filters) keeps efficiency up, prevents mid-season breakdowns, and protects your manufacturer warranty, which often requires documented annual service.

Question 7

Why is my AC running but not cooling?

Accepted Answer

The most common causes are a clogged air filter, a refrigerant leak, a frozen evaporator coil, or a failing capacitor on the outdoor unit. Check the filter first. If airflow is fine and it's still blowing warm, shut the system off to prevent compressor damage and call us at 603-475-9027 — running it in that state makes repairs more expensive.

Question 8

What areas do you serve?

Accepted Answer

We're based in Kingston, NH and serve all of New Hampshire, southern Maine, Vermont, and Massachusetts. Most of our work is in Southern NH — Kingston, Exeter, Epping, Derry, Londonderry, Salem, and surrounding towns.
