We Know
Concord Homes.
Concord combines the historic neighborhoods of New Hampshire's capital with multi-family housing and newer development to the south and west. A.J. LeBlanc Heating works across that full range, from century-old homes near downtown to later construction along the city's outer corridors.
Housing: About one-third of Concord's housing predates 1940, a larger share than any other building era in the city. Downtown neighborhoods include Victorian-era homes and old colonials, while building during the 1970s and 1980s added many capes and ranches in South Concord and Penacook. Newer development extends along the I-93 corridor. Close to half of the city's housing units are in multi-family buildings, from two- and three-family homes to converted houses and larger apartment buildings, and the median Concord home dates to 1969.
Furnaces, Boilers &
Heat Pumps
Heating in Concord
Liberty Utilities provides natural gas in much of Concord, with availability depending on the street and address. A.J. LeBlanc Heating services and replaces gas boilers and furnaces where a connection is available, along with oil and propane systems in older neighborhoods and areas beyond the gas network. Concord's pre-1940 homes also include steam and gravity hot-water systems that require careful evaluation of the existing radiators, piping, venting, and controls. We can replace the boiler, improve zoning, or complete an oil-to-gas conversion when the home and utility service support it.

Air Conditioning &
Mini Split Installation
Cooling in Concord
Many of Concord's older, boiler-heated homes would need a new duct system for central A/C. Mini splits can provide cooling in separate zones with less disruption to old plaster and original woodwork. Ranches, capes, and other homes with suitable ducts may also accommodate central A/C or a ducted heat pump. In two- and three-family buildings, separate mini split zones can give each living space its own control. A.J. LeBlanc Heating plans the equipment around the home's layout, electrical capacity, and existing heating system.
Cooling Services We Provide
We provide complete cooling service in Concord 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 Concord
Concord's public water comes mainly from Penacook Lake, with the Contoocook River available as another source and the Pembroke Well Field maintained for emergencies. The city uses carbon filtration, corrosion-control treatment, and chloramine disinfectant. A.J. LeBlanc Heating can install carbon equipment sized to reduce a defined chloramine-related taste or odor, along with under-sink carbon or reverse osmosis systems for drinking and cooking water.
Properties outside the public system need an independent laboratory test because the city's report does not describe private-well water. Depending on the results, treatment may include sediment filtration, iron or manganese treatment, a softener for measured hardness, ultraviolet treatment for confirmed bacteria, or arsenic treatment. If testing identifies radon in well water, we can provide contact information for an independent mitigation company.
Water Treatment Services We Provide
We install and service water-treatment systems for Concord 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

Plumbing in Concord
Concord's century homes, multi-family properties, and later suburban houses contain a wide range of plumbing systems. A.J. LeBlanc Heating repairs leaking fixtures and connections, worn valves, running toilets, damaged supply pipes, household drains, and water heaters. Repeated drain trouble in an older home can sometimes trace back to deteriorated cast iron, and we can replace the affected piping when its condition is causing the failure.
We inspect the system, show the homeowner what we found, and recommend a repair that fits the problem rather than a larger project than the home needs.
