We Know
Derry Homes.
Derry is one of the larger towns in Southern NH and has a widely varied mix of housing. Older neighborhoods clustered around the village center, newer subdivisions out toward East Derry, and rural stretches in between.
Housing: Ranches, capes, and split-levels from the 50s through 70s in the older parts of town. Newer subdivision homes out toward the Chester and Auburn lines. There is also real rural character along some of the back roads with older farmhouses on larger parcels.
Heating: Oil heat is very common here, especially in the older parts of town. We do significant boiler and furnace work in Derry and we see more homeowners switching to heat pumps every year, mostly because oil prices have made a strong argument for it.
Cooling: A lot of Derry's older homes were heated with boilers, no ductwork. Mini splits are the right answer for those houses. Add heating and cooling at the same time without tearing up the ceilings.
