We Know
Brookline Homes.
Brookline has grown rapidly while retaining wooded lots and a small-town setting about 12 miles west of Nashua. A.J. LeBlanc Heating serves homes near the meeting of Routes 13 and 130 and throughout the neighborhoods between Milford and Hollis.
Housing: About 94 percent of Brookline's housing consists of single-family homes, roughly 95 percent is owner-occupied, and only a small share is multi-family. Building accelerated during the 1990s, with close to half of all units added from 1990 through 2009. The median home dates to 1993, although pre-1940 farmhouses and houses from the 1970s and 1980s remain in the mix. Many properties combine newer construction with large wooded lots.
Heating: Oil and propane are Brookline's main delivered heating fuels, and the town has no natural gas service. A.J. LeBlanc Heating repairs, maintains, and replaces oil and propane boilers and furnaces. Cold-climate heat pumps can provide another heating and cooling option in both older farmhouses and newer homes. We compare that equipment with the home's existing system, distribution, electrical capacity, and comfort goals before recommending a path.
Cooling: Many Brookline homes with boiler heat were not built with central-air ductwork. A mini split system can provide zoned cooling and supplemental heat without building a new duct network. Homes with suitable forced-air ducts may be served by central air conditioning or a ducted heat pump after airflow and capacity are verified. A.J. LeBlanc Heating sizes either system to the home rather than relying on the old equipment alone.
