We Know
Kingston Homes.
Kingston is one of New Hampshire's oldest towns, centered on the historic village green known as the Plains. A.J. LeBlanc Heating serves older homes near the center and later properties around Great Pond, Kingston State Park, and the town's rural roads.
Housing: About 83 percent of Kingston's housing units are single-family homes, with much of the stock built during the 1970s and 1980s. Older colonials and New Englanders remain near the village, where a smaller share of multi-family housing is also found. That mix gives Kingston boiler-heated historic homes, later forced-air houses, and newer heat-pump installations within the same service area.
Furnaces, Boilers &
Heat Pumps
Heating in Kingston
Oil and propane heat many Kingston homes, while Unitil lists natural gas service in part of town. A.J. LeBlanc Heating confirms gas availability for the address before presenting conversion or replacement options. We service and replace oil and propane boilers and furnaces, work on natural-gas equipment where service is available, and install cold-climate heat pumps for homeowners adding cooling or reducing delivered-fuel use. Each system is sized to the home and its existing distribution.

Air Conditioning &
Mini Split Installation
Cooling in Kingston
Many older Kingston homes use boilers and radiators and would need a new duct system for central A/C. A properly designed mini split can deliver zoned cooling without building a new duct network. Homes with suitable existing ducts may be good candidates for central A/C or a ducted heat pump. A.J. LeBlanc Heating evaluates the floor plan, airflow, electrical capacity, and existing equipment before recommending either approach.
Cooling Services We Provide
We provide complete cooling service in Kingston 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.

Filtration, Softeners
& Testing
Water Treatment in Kingston
Most Kingston homes use private groundwater wells, and the town does not have one system serving every address. The Kingston Health Department recommends regular testing because many groundwater contaminants cannot be seen, smelled, or tasted. A documented PFAS (per- and polyfluoroalkyl substances) investigation area near Main Street and the fire station is targeted and does not describe the entire town.
A.J. LeBlanc Heating submits collected samples to an independent laboratory and follows the property results and any location-specific guidance. Treatment may include ultraviolet equipment for confirmed bacteria, arsenic filtration or under-sink reverse osmosis, sulfur-odor treatment, or contaminant-specific PFAS equipment with verified performance. For a confirmed radon-in-water result, we refer the homeowner to an independent mitigation company.
Water Treatment Services We Provide
We install and service water-treatment systems for Kingston 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
- Water Sampling & Independent Laboratory Testing
