We Know
Nashua Homes.
Nashua is NH's second largest city and a busy part of our service area. The housing mix is wide, from 1940s in-town colonials to newer suburban neighborhoods on the edges.
Housing: The neighborhoods closer to downtown have 1940s and 50s colonials and capes, some with original heating systems still running. The suburban areas to the north and west are mostly 80s and 90s construction. The Harbor area and the older neighborhoods near Salmon Brook are older stock with more boilers.
Heating: Gas coverage is good throughout most of Nashua, so forced hot air systems are common in the newer areas. The older in-town neighborhoods are more likely to have boilers.
Cooling: A lot of Nashua's homes were built with ductwork, so central A/C is common here. Mini splits are growing in popularity in the older neighborhoods that were built before central air was standard.
