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.
Heating: 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.
Cooling: 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.
