New Hampshire HVAC leads

How New Hampshire homes are heated

Delivered fuels heat most New Hampshire homes. The Census Bureau’s table B25117 (ACS 2020-2024) has fuel oil or kerosene as the main heating fuel in 186,399 of 404,453 owner-occupied homes (46.1%, 3rd highest of the states) and bottled, tank or LP gas in 87,185 (21.6%, the highest share of any state). Electricity heats 5.2%, the lowest share in the country.

Counting renters as well, table B25040 (2020-2024 ACS) puts utility gas at 21.4% and electricity at 11.1% of 555,822 occupied homes. For an HVAC buyer this mix points to boilers and furnaces fired by oil or propane, with tank and burner work, in most owner homes. The shares describe the housing, not where any request originates.

New Hampshire HVAC contractor licensing

State trade licensing for heating work in New Hampshire runs through the Mechanical Licensing Board, part of the Office of Professional Licensure and Certification, whose page lists who it regulates. The list has no separate HVAC or air-conditioning contractor license:

• Fuel gas fitters: trainee, installation, service, piping, domestic appliance, and hearth system installation and service categories.
• Plumbers: trainee, journeyman and master.
• Oil heating technicians: a voluntary license.
• Business entities: corporations, LLCs and partnerships.

The board page states that the codes it applies were updated to the 2021 editions effective July 1, 2024. Its laws and rules page names RSA 153:27 through 153:38 as the governing statute, with the board’s Mec rules beside it.

For a buyer, that means the license to look for depends on the fuel: gas and propane appliance work falls under the fuel gas fitter categories, while the board lists its oil heating technician license as voluntary. Refrigerant handling on air conditioners and heat pumps requires federal certification under EPA Section 608. The general contractor question is covered on the window replacement page linked below.

New Hampshire counties by owner-occupied homes

All ten New Hampshire counties are listed, largest owner-occupied count first, with the share of owner homes heated by fuel oil and by propane, the state’s two main fuels. Source: ACS 5-year 2020-2024, county tables B25003 and B25117. The table describes housing and nothing about where leads come from.

Coos County relies most on oil, at 70.9% of owner homes, with Cheshire next at 62.5%. Carroll (30.1%) and Grafton (28.6%) have the highest propane shares. Hillsborough has both the lowest oil share and the highest utility gas share, 32.4% of its owner homes, in the same county data (2020-2024 ACS).

What New Hampshire HVAC buyers filter on

New Hampshire HVAC buyers typically work with four filters, each linked to the facts above:

• Project type: for example install, replace or repair, for heating or cooling. Heating work leads in a state with 7,371 heating degree days (NOAA NCEI, 2025).
• Homeowner status: 404,453 owner-occupied homes, the households that decide on a new boiler or furnace (ACS 2020-2024, B25003).
• Timeframe: a no-heat call in January needs a fast visit; a planned fuel conversion does not.
• ZIP code: a buyer can match its fuel skills, for example oil-heavy Coos or Cheshire County ZIP codes, or Hillsborough County for gas.

When HVAC opens, New Hampshire buyers will set these filters per campaign, down to the ZIP code, as on Summit’s other home services leads. Once HVAC opens, HVAC leads will be exclusive by default, with shared delivery on request. The request fields appear on the sample HVAC lead.
