We Know
Dunbarton Homes.
Dunbarton is a rural upland town in Merrimack County, with small village areas at Dunbarton Center and Pages Corner. A.J. LeBlanc Heating serves homes set along its back roads and on large lots beyond a typical suburban street grid.
Housing: Nearly every Dunbarton housing unit is an owner-occupied, single-family home on a large lot. About half were built from the 1990s onward, so newer colonials and capes stand near older farmhouses and classic New Englanders. Most properties use private wells, and no natural gas service reaches town. The housing range supports both older oil systems and newer propane or heat-pump equipment.
Heating: Dunbarton homes rely mainly on oil and propane, with no natural gas service in town. A.J. LeBlanc Heating repairs and replaces oil and propane boilers and furnaces in older farmhouses, later capes and colonials, and newer homes. Cold-climate heat pumps can supplement or replace delivered-fuel systems when the home and electrical service support them. We compare the existing equipment, heating needs, distribution system, and fuel goals before recommending a path.
Cooling: Many older Dunbarton homes use boiler heat and were not built with ducts for central A/C. A ductless heat-pump system can deliver room-by-room cooling and supplemental heat without opening finished walls for new ducts. Newer homes with suitable forced-air ductwork may be served by central air conditioning or a ducted heat pump. A.J. LeBlanc Heating evaluates the home's layout, electrical capacity, and existing equipment before sizing the system.
