Heat pump repair in Portsmouth can be a cooling complaint in July or a heating complaint in January. 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. Ice on the outdoor unit, a backup heat strip that never shuts off, or lukewarm air are different faults. 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. Say how old the system is and whether anyone has added refrigerant. 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. A dual-fuel system still has the old furnace or boiler. Tell the contractor which one is running. They quote after diagnosis. Confirm insurance.
