We Know
New Boston Homes.
New Boston centers on a compact historic village along the Piscataquog River, with its white church and common surrounded by older homes. Beyond the village, A.J. LeBlanc Heating serves single-family properties spread along the town's rural roads.
Housing: About 86 percent of New Boston's housing units are single-family homes, with only a small multi-family share. Older farmhouses, New Englanders, and antique colonials remain around the historic village, while most of the town's housing was built from the 1970s onward. The median home dates to about 1989, and 1990s colonials are common along the back roads. On the same service day, our team may work in a tight antique utility room and a later home with a modern mechanical system.
Furnaces, Boilers &
Heat Pumps
Heating in New Boston
New Boston has no natural gas service, so homes rely on oil, propane, electricity, and heat pumps. Oil equipment accounts for much of the existing housing stock, including boilers and furnaces in older homes. A.J. LeBlanc Heating services and replaces that equipment and installs cold-climate heat pumps where the layout and electrical capacity support them. In tight utility rooms, we measure carefully and plan the piping, venting, and service access before selecting a replacement.

We take care of all heating equipment in New Boston. From routine annual service to emergency repairs and full system replacements, our team is ready to help.

Air Conditioning &
Mini Split Installation
Cooling in New Boston
Many older New Boston homes were designed around boilers or radiators and lack a duct system for conventional central cooling. A mini split system can provide zoned cooling with limited disruption to antique framing and finished walls. Later colonials with suitable forced-air ducts may be suited to central A/C or a ducted heat pump. A.J. LeBlanc Heating sizes either system to the home, from compact antique capes to more open modern floor plans.
Cooling Services We Provide
From central air conditioning to heat pumps and ductless mini splits, we handle cooling installation and service in New Boston. We have completed thousands of ductless installations across Southern NH. Call us for a quick response to a summer breakdown or full system replacement.

Water Treatment in New Boston
New Boston has private wells along with several regulated public-water supplies, so the source depends on the address. New Boston Space Force Station has a documented PFAS (per- and polyfluoroalkyl substances) investigation history connected with historic firefighting foam, but that site history is not a reading for a nearby home. A private-well owner may add PFAS analysis when location, prior results, or current agency guidance supports it.
A.J. LeBlanc Heating starts by collecting samples for an independent laboratory and uses the full panel to select treatment for sediment, iron, manganese, measured hardness, sulfur odor, confirmed bacteria, arsenic, or PFAS. Any PFAS recommendation requires verified product performance. If radon is confirmed in well water, we can provide contact information for an independent mitigation company, while public-system customers can begin with the report for their supplier.
Water Treatment Services We Provide
We install and service water-treatment systems throughout New Boston. When testing is needed, we send a water sample to an independent laboratory and use the results to select and size the appropriate equipment.
- Well Water Filtration
- Water Softeners
- Iron & Manganese Removal
