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.
Furnaces, Boilers &
Heat Pumps
Heating in Dunbarton
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 in Dunbarton
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.
Cooling Services We Provide
From central air conditioning to heat pumps and ductless mini splits, we handle cooling installation and service in Dunbarton. We have completed thousands of ductless installations across Southern NH. Call us for a quick response to a summer breakdown or full system replacement.

& Testing
Water Treatment in Dunbarton
Dunbarton homes generally use private wells, although a small number of regulated systems serve other properties. A broader state study included the area in targeted arsenic and uranium testing, but its pooled results do not show what is present in an individual well. A.J. LeBlanc Heating collects a current sample for an independent laboratory and builds treatment around the findings.
Confirmed arsenic may be addressed with under-sink reverse osmosis or whole-house filtration, while uranium requires equipment selected and verified for that contaminant. Other results may support sediment, iron, manganese, hardness, sulfur-odor, or ultraviolet treatment. When testing confirms radon in the water, we give the homeowner a referral to an independent mitigation company.
Water Treatment Services We Provide
We install and service water-treatment systems throughout Dunbarton. When testing is needed, we send a water sample to an independent laboratory and use the results to select and size the appropriate equipment.
- Well Water Filtration
- Water Softeners
- Iron & Manganese Removal
