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.
Furnaces, Boilers &
Heat Pumps
Heating in Windham
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.

Air Conditioning &
Mini Split Installation
Cooling in Windham
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.
Cooling Services We Provide
Windham homeowners can call us for central air conditioning, heat pumps, and ductless mini splits. Our team has installed thousands of ductless systems throughout Southern NH. We respond quickly for summer breakdowns and full system replacements.

Water Treatment in Windham
Most Windham homes use private wells, with limited areas served by Pennichuck community systems. The town has documented PFAS (per- and polyfluoroalkyl substances) response work associated with specific fire-station properties and historic firefighting practices. That localized history is not a finding about wells throughout Windham.
A.J. LeBlanc Heating sends private-well samples to an independent laboratory and selects treatment from the results. Options may include iron, manganese, measured hardness, sulfur odor, ultraviolet equipment for confirmed bacteria, or arsenic treatment, while a PFAS result requires contaminant-specific equipment with verified performance. Community-system customers may choose whole-house activated carbon for better taste or a dedicated carbon or reverse osmosis system for drinking and cooking water.
Water Treatment Services We Provide
We provide water-treatment installation and service in Windham. Independent laboratory results guide every private-well recommendation, from drinking-water filtration to complete whole-house treatment.
- Well Water Filtration
- Water Softeners
- Iron & Manganese Removal
- Reverse Osmosis Drinking Water
