A.J. LeBlanc Heating has served Brentwood and Southern NH since 1928. Licensed technicians, honest estimates, and 24/7 emergency service.
We Know
Brentwood Homes.
Brentwood is a quiet rural community between the Seacoast and the interior. Open space, older properties, and a character that has not changed much.
Housing: Older farmhouses and rural homes alongside newer single-family construction. No gas service in most of the town, so oil and propane are the standard.
Heating: Oil and propane are what we work with in Brentwood. Boiler and furnace replacements and heat pump installations are the most common jobs.
Cooling: Mini splits and heat pumps are the practical choice for these homes. They work well in older structures and do not require fuel delivery.
