We Know
Nashua Homes.
Nashua is New Hampshire's second-largest city and one of the busiest parts of our service area. Its nearly even mix of single-family and multi-family housing ranges from pre-1940 neighborhoods near the center to newer homes toward the edges of the city, with the median home dating to 1976.
Housing: Nashua's pre-1940 core includes colonials and capes along with Late Victorian, Italianate, and Federal homes around French Hill. Nearly half of the city's housing units are in multi-family buildings, including two- and three-family homes and larger apartment buildings near the Millyard. Suburban neighborhoods to the north and west grew largely during the 1970s and 1980s, with newer construction mixed in. The median Nashua home dates to 1976, so the city contains several generations of heating, cooling, plumbing, and electrical systems.
Heating: Liberty Utilities provides natural gas across much of Nashua. Forced-air gas heat is common in many suburban neighborhoods, while older in-town homes and multi-family buildings often use boilers, including oil-fired equipment. A.J. LeBlanc Heating replaces furnaces and boilers, completes oil-to-gas conversions where service is available, and works on oil and propane systems where it is not. In a multi-family building, we also evaluate the existing zones and whether one system serves more than one unit before recommending a replacement.
Cooling: Nashua homes with suitable forced-air ductwork may be good candidates for central A/C or a ducted heat pump. Many pre-1940 homes downtown, French Hill houses, and multi-family buildings do not have those ducts. In these homes, a mini split system can add zoned cooling without cutting through extensive finished space. A.J. LeBlanc Heating checks airflow, duct capacity, electrical capacity, and the building layout before designing the system. In a two- or three-family property, separate mini split zones can also keep each living space under its own control.
