We Know
Windham Homes.
Windham has grown into one of the more desirable communities near the Massachusetts border. Newer housing, good schools, and a steady stream of Boston-area buyers who want NH taxes.
Housing: Mostly colonials and contemporaries built from the 90s through today. Windham developed late and quickly, so the housing is relatively uniform in age. Some older properties remain along the rural roads.
Heating: Gas and heat pump systems are common in the newer homes. Oil heat is still around in the older properties on the rural roads that predate the development wave.
Cooling: Central A/C is common in Windham because a lot of these homes were built with it. Mini splits are popular for homeowners who want better zone control or more efficiency.
