We Know
Plaistow Homes.
Plaistow sits on the Massachusetts line, with most shops and businesses along Route 125 and residential neighborhoods behind that corridor. A.J. LeBlanc Heating serves single-family homes, two- and three-unit properties, and small residential buildings throughout town.
Housing: Single-family houses account for about three-quarters of Plaistow's housing, while nearly one-quarter of the units are in multi-family buildings. Construction was strongest during the 1970s and 1980s, especially the 1980s, producing many ranches and capes. Older houses and newer builds add further variety. The housing mix requires equipment and service plans that account for both individual homes and shared residential buildings.
Furnaces, Boilers &
Heat Pumps
Heating in Plaistow
Oil remains common in Plaistow's ranches, capes, and older homes. Unitil natural gas is available in parts of the Route 125 corridor, with service confirmed for the address. A.J. LeBlanc Heating repairs and replaces oil, propane, and gas boilers and furnaces and installs cold-climate heat pumps. We help homeowners compare the available fuels and equipment based on the house, its distribution system, and utility access.

Air Conditioning &
Mini Split Installation
Cooling in Plaistow
Many older oil-heated Plaistow ranches and capes would need new ductwork to use central A/C. Mini splits can provide cooling in separate zones along with supplemental heat during milder weather, without a major duct project. Homes with a forced-air furnace and suitable ducts give us the option of central A/C or a ducted heat pump. A.J. LeBlanc Heating sizes either option to the home rather than relying on a standard package.
Cooling Services We Provide
We install and service central air conditioning, heat pumps, and ductless mini splits in Plaistow. We have installed thousands of ductless systems across Southern NH. Whether you need a summer repair or a complete replacement, we respond quickly.

Water Treatment in Plaistow
Plaistow has both public water and private wells. The municipal supply comes through Hampstead Area Water Company's Core Water System, which blends water from local bedrock wells with the Southern New Hampshire Regional Water Connection. That regional connection was developed in part because of limited local supply and past methyl tert-butyl ether (MTBE) concerns in some areas.
PFAS (per- and polyfluoroalkyl substances) has also been documented in some private wells near municipal mains. Neither condition is present at every address. A.J. LeBlanc Heating starts with private-well samples collected for an independent laboratory and selects sediment, iron, manganese, hardness, bacteria, PFAS, or MTBE treatment from the results.
PFAS and MTBE equipment must have verified performance for the substance measured. Company-water customers may choose whole-house carbon for a taste or odor concern, or an under-sink carbon or reverse osmosis system for drinking and cooking water.
Water Treatment Services We Provide
Plaistow homeowners can call us for water-treatment installation and service. For a private well, an independent laboratory analyzes the sample before we select and size the treatment equipment.

- Iron & Manganese Removal
