An AC repair call in Dover 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. Outdoor equipment needs to sit above snow that slides off a mill roof or a steep house roof. Salt air reaches Dover on some storms, and coils and disconnects corrode. If the coil is iced, turn the system off and say how long it has been off. Brick mill buildings and the older streets around the Cochecho were not designed for ducts. Radiators and baseboard are common. Later streets mix capes and colonials on oil or gas. Converted mill space crams equipment into closets. 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. Northern Utilities is the gas map that applies here more often than Liberty's Merrimack Valley list. Unitil electric territory covers much of the seacoast. Confirm both on the bills. The contractor quotes after seeing the equipment. This site does not warrant the work.
