We Know
Penacook Homes.
Penacook is Concord's northern village, with its own ZIP code, post office, and village association. It grew along the Contoocook River, which falls about 100 feet in a little more than a mile before joining the Merrimack. A.J. LeBlanc Heating serves its mill-era homes, postwar neighborhoods, multi-family properties, and newer development.
Housing: Penacook has an unusually broad housing mix for a village its size. Nineteenth-century mill homes and older New Englanders stand near the river, while postwar capes and ranches fill nearby single-family neighborhoods. The village also includes converted two- and three-family houses, manufactured homes, and newer apartments closer to the main roads. Each building type brings different mechanical-space, access, zoning, and equipment needs.
Furnaces, Boilers &
Heat Pumps
Heating in Penacook
Penacook's mill-era homes and postwar neighborhoods use oil, propane, and natural gas. Liberty Utilities serves parts of the village, with availability confirmed for the address. A.J. LeBlanc Heating repairs and replaces boilers and furnaces and plans oil-to-gas or cold-climate heat-pump conversions where they fit the property. In compact older mechanical rooms, we account for service access, piping, venting, controls, and electrical needs before laying out the replacement.

Penacook 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 Penacook
Many older Penacook homes use boiler heat and have no central cooling ducts. A mini split system can add room-by-room cooling and supplemental heat without a major duct project. Postwar and newer homes with suitable warm-air ducts may be served by central air conditioning or a ducted heat pump. A.J. LeBlanc Heating evaluates the building layout and any multi-family zoning needs before selecting equipment.

We install, repair, and service all types of cooling equipment in Penacook, 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 Penacook
Penacook-Boscawen Water Precinct uses groundwater wells and treats its supply for pH, corrosion control, and disinfection. Those steps apply to precinct water, not private wells outside its service area. Precinct customers can begin with the utility report and choose whole-house activated carbon or an under-sink carbon or reverse osmosis system for a specific taste, odor, or drinking-water goal.
A.J. LeBlanc Heating collects the private-well sample for independent laboratory analysis and uses the results to select sediment, iron, manganese, hardness, sulfur-odor, ultraviolet, or arsenic treatment. When radon mitigation is recommended, we direct the homeowner to an independent company.
Water Treatment Services We Provide
Our team installs and services water-treatment equipment for Penacook homes. We use independent laboratory results for private wells and the utility report and condition at the tap for public-water homes.

- Iron & Manganese Removal
