Heat pump installation in Portsmouth starts from the design temperature and the fuel you have now. Gas on the seacoast is Northern Utilities, the Unitil gas company. Electric service is often Unitil as well. Read the bill. A main on a regional map is not a main on your lane. Downtown wood-frame houses, some from the 18th and 19th centuries, often never gained a full duct system. Hot water and steam are still in those houses. Forced air shows up in later neighborhoods. A cold-climate unit is not a slogan. Ask which rooms have no duct or no head, and what happens on the coldest morning. Salt air is hard on outdoor coils and on electrical connections. Fog plus a hot week plugs coils. Grade-level units sit where nor'easter drifts collect. NHSaves rebates follow the electric account and the equipment list, not the city name. Read the rebate guide and the official page before you count on a figure. The City of Portsmouth runs its own inspections. Old houses raise questions about where a line set can penetrate. Ask who pulls the permit. The contractor quotes after a load look. This site does not file the rebate.
