We Know
Amherst Homes.
Amherst combines a carefully preserved village center with larger-lot neighborhoods around it. A.J. LeBlanc Heating works in historic homes near the common, houses built during the town's later growth decades, and newer custom properties throughout town.
Housing: About 93 percent of Amherst's housing units are single-family homes, and nearly the same share are owner-occupied. Older colonials and capes surround the village common, while the 1970s and 1980s account for roughly 44 percent of the town's houses. Additional neighborhoods followed from the 1990s onward, and the median Amherst home dates to about 1978. Many properties sit on generous lots, which can affect equipment location and the way additions or separate living areas are served.
Furnaces, Boilers &
Heat Pumps
Heating in Amherst
Liberty Utilities provides natural gas in parts of Amherst, while many homes in the village and outlying neighborhoods use oil or propane. A.J. LeBlanc Heating services and replaces equipment for all three fuels. In older hot-water systems, we evaluate the boiler, controls, radiators, and nearby piping together rather than treating the appliance as an isolated component. Where natural gas is available at the address, we can review an oil-to-gas conversion, and cold-climate heat pumps offer another option for homes with the right layout and electrical capacity.

Amherst homeowners can call us for heating installation, repairs, and annual service. We also replace complete heating systems and respond quickly when something goes wrong.

Air Conditioning &
Mini Split Installation
Cooling in Amherst
Many older Amherst homes use hot-water heat and lack central-air ductwork. A mini split system can add cooling with limited disruption to historic finishes, and larger homes may benefit from a carefully planned multi-zone layout. Properties with suitable forced-air ducts may be served by central air conditioning or a ducted heat pump. A.J. LeBlanc Heating evaluates room layout, exposure, airflow, and the existing system before sizing the equipment.
Cooling Services We Provide
We install, repair, and service all types of cooling equipment in Amherst, including central air, heat pumps, and ductless mini splits. With thousands of ductless installations completed across Southern NH, our team has extensive experience. We respond quickly when you need a repair or replacement.

Water Treatment in Amherst
Amherst has many private wells and limited public-water service. Documented PFAS (per- and polyfluoroalkyl substances) investigations and public-water extensions have involved defined areas near Cobbler Lane and Thatcher Drive, but those response areas do not describe every Amherst well. A.J. LeBlanc Heating sends private-well samples to an independent laboratory and includes PFAS testing when the location or current state guidance supports it.
Depending on the results, treatment may include sediment, iron, manganese, measured hardness, sulfur odor, ultraviolet equipment for confirmed bacteria, or arsenic treatment. A PFAS result requires contaminant-specific equipment with verified performance. Public-water customers may choose activated carbon or a dedicated drinking-water system for a specific goal at the tap.
Water Treatment Services We Provide
Our team installs and services water-treatment equipment for Amherst homes. We use independent laboratory results for private wells and the utility report and condition at the tap for public-water homes.

- Water Softeners
- Iron & Manganese Removal
- Reverse Osmosis Drinking Water
