Find an HVAC technician in Dover, NH

Dover grew up on the Cochecho River's falls, and its mill-era housing grew up around 19th-century heating technology — much of it still in service. Triple-deckers, duplexes, and brick worker housing around downtown Dover run aging furnaces and boilers through deep freezes; ice dams are routine on the steep roofs, and unheated entryways and exterior-wall duct runs punish forced-air systems.

No-heat calls are the winter emergency, and ice storms add a second threat: power loss kills heat for every fuel type, and ice-laden venting chokes furnaces and boilers. Summers turn genuinely humid along the Merrimack Valley, but many older homes have no central AC — window units and ductless mini-splits fill the gap.

Mill-era triple-deckers, duplexes, and worker housing line the streets around downtown — most with full basements, granite-block and fieldstone foundations, and heating equipment that's been repaired for a hundred years. Boilers and furnaces from the early 1900s are living on borrowed time; freeze-thaw winters punish venting and flues, and ice dams are routine on the steep roofs. Many of these buildings have been converted to rentals, where deferred maintenance lets small heating problems become midwinter emergencies.
