Across 21 cities, the dominant HVAC profile is dual-fuel: with median 6,200 heating degree days and 900 cooling degree days, the typical home benefits from a dual-fuel setup — a heat pump for mild days plus a gas furnace that takes over during deep cold snaps.

New Hampshire does not issue a statewide HVAC contractor license. Gas-fired equipment requires a state Gas Fitter license issued by the Mechanical Licensing Board under the Office of the State Fire Marshal — verify at nh.gov/safety/divisions/firesafety/licensing/mechanical-licensing.html. Electrical hookups need a state Master Electrician license from the NH Electricians' Board. Cities like Manchester, Nashua, and Concord may require a local business registration. Always confirm current general-liability insurance and the appropriate gas/electrical credentials.
