We Know
Henniker Homes.
Henniker is a college town along the Contoocook River, incorporated in 1768 and home to New England College since 1946. A.J. LeBlanc Heating serves older village homes, rental properties near the campus, and later neighborhoods toward the edges of town.
Housing: Nearly half of Henniker's housing was built during the 1970s and 1980s, including many capes and ranches, and the median home dates to 1974. Victorian-era homes remain near the village, while pre-1940 houses account for about one-quarter of the stock. New England College contributes to a multi-family and rental share of more than one-quarter of all units. Newer construction fills in toward the town's outer areas.
Furnaces, Boilers &
Heat Pumps
Heating in Henniker
Oil is the most common heating fuel in Henniker, while homes without oil use propane, electricity, or heat pumps in a town with no natural gas service. Older village properties often have oil boilers serving radiators or baseboard, and a replacement may also require attention to nearby piping, circulators, controls, chimney, or venting. A.J. LeBlanc Heating evaluates the complete system before comparing high-efficiency oil, propane, and cold-climate heat-pump options. Later capes and ranches receive the same home-specific sizing and planning.

Cooling in Henniker
Many Henniker village homes, oil-heated capes, and rental properties were built without central-air ductwork. Ductless equipment can provide room-by-room cooling and supplemental heat without a major duct project, including separate zones for multi-family living spaces. Ranches and other homes with suitable forced-air ducts may accommodate central A/C or a ducted heat pump. A.J. LeBlanc Heating evaluates the layout, existing equipment, and electrical capacity before recommending a system.
Cooling Services We Provide
We provide complete cooling service in Henniker for central air conditioners, heat pumps, and ductless mini splits. Our team has installed thousands of ductless systems across Southern NH. We respond quickly for both unexpected breakdowns and complete replacements.

Water Treatment in Henniker
Cogswell Spring Water Works serves part of Henniker from groundwater wells. The utility adds sodium hydroxide to raise pH and reduce corrosion, then uses sodium hypochlorite to disinfect the water. Cogswell customers can begin with the utility report and consider whole-house activated carbon or an under-sink carbon or reverse osmosis system for a specific household goal.
Other Henniker homes use private wells, and A.J. LeBlanc Heating submits collected samples to an independent laboratory before selecting iron, manganese, hardness, sulfur-odor, ultraviolet, or arsenic treatment. If the results call for radon aeration, we can direct the homeowner to an independent company.
Water Treatment Services We Provide
We install and service water-treatment systems for Henniker homes. When a private-well test is needed, we collect a sample and send it to an independent laboratory. We use the results to size anything from an under-sink drinking-water filter to a whole-house system.
- Well Water Filtration
- Water Softeners
- Iron & Manganese Removal
- Reverse Osmosis Drinking Water
- UV Purification
