We Know
Dunbarton Homes.
Dunbarton is one of the more rural communities in southern NH. Small population, low density, and a character the town guards closely.
Housing: Farmhouses, older New Englanders, and some newer single-family homes on large lots. Most properties are on well and septic. Natural gas is not available.
Heating: Oil and propane are the choices in Dunbarton. We do boiler and furnace work here and have seen steady interest in heat pumps from homeowners who want to reduce their fuel costs and have the electrical capacity to support one.
Cooling: Mini splits work well in Dunbarton's older homes. They do not require ductwork, they add cooling and heating in one system, and they tend to run quietly. Standby generators are popular given the rural location.
