An HVAC tune-up in Dover is a heating visit, a cooling visit, or both. It is not a repair unless something has failed. 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. 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. Fall is the useful time for the burner. Spring is the useful time for the coil and the drain, before the first heat wave. 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. Ask what the visit includes and what would be quoted separately. Confirm license and insurance. Call (603) 420-0791 with the ZIP.
