We Know
Windham Homes.
Windham sits in southwestern Rockingham County a few miles north of the Massachusetts line. Its population grew from 13,592 in 2010 to 15,817 in 2020, adding new neighborhoods while older homes remained along the rural roads A.J. LeBlanc Heating serves.
Housing: About 98 percent of Windham homes are single-family houses, and the median home dates to about 1996. Much of the town's development occurred during the 1990s and 2000s, creating neighborhoods of colonials and contemporary homes, with additional houses built since 2010. The housing stock also includes a substantial group from the 1970s and 1980s and a smaller number of older houses along rural roads. Those building eras support different combinations of central air, boiler heat, and later heat-pump additions.
Heating: Oil is the most common heating fuel in Windham. Liberty provides natural gas at some addresses, with availability confirmed for the specific street, while other homes use oil, propane, or heat pumps. A.J. LeBlanc Heating services and replaces furnaces and boilers across those fuels and installs cold-climate heat pumps when they fit the home. We compare the existing system, heating needs, fuel availability, ductwork or piping, and electrical capacity before recommending a replacement.
Cooling: Many newer Windham homes were built with central-air ductwork, so A.J. LeBlanc Heating often replaces or upgrades existing central A/C systems in those neighborhoods. Older houses along rural roads may use boiler heat and have no usable ducts. Mini splits can provide cooling in separate zones and efficient supplemental heat to those homes, as well as to bonus rooms or finished spaces that the central system does not serve well. We size each system around the actual layout and comfort needs.
