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.
Heating: 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.
Cooling: 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.
