An AC repair call in Portsmouth is about what the system is doing today, not a printed price. Warm air, a condenser that short-cycles, ice on the line, or a drain that overflows are different jobs. 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. If the coil is iced, turn the system off and say how long it has been off. 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 tight return or a packed filter will make a healthy compressor look weak. Say whether the outdoor unit is a straight air conditioner or a heat pump. 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. The contractor quotes after seeing the equipment. This site does not warrant the work.
