We Know
Sandown Homes.
Sandown grew from a small rural town into a residential community of more than 6,500 people. A.J. LeBlanc Heating serves year-round neighborhoods and the homes near Angle Pond and the town's other small ponds.
Housing: Most Sandown housing consists of owner-occupied, single-family homes built from the 1980s through the 2000s, with the median house dating to about 1986. A smaller pre-1940 core remains, along with former seasonal cottages near the ponds. Some Angle Pond camps and other seasonal buildings have been converted for year-round living. Those conversions deserve careful evaluation because the structure and mechanical systems may have been designed for limited seasonal use and updated in stages.
Heating: Oil is Sandown's most common heating fuel, followed by propane, and the town has no natural gas service. A.J. LeBlanc Heating replaces oil and propane boilers and furnaces and installs cold-climate heat pumps for homeowners who want to reduce delivered-fuel use. Converted cottages near the ponds need extra attention because their heating equipment and distribution may have been added for a different level of use. We evaluate the structure, existing system, and heating needs before sizing a replacement.
Cooling: Many older Sandown homes and converted cottages lack a duct system for conventional central cooling. A mini split system can provide quiet, zoned cooling without a major duct project. Later single-family homes with suitable forced-air ducts may be served by central air conditioning or a ducted heat pump. A.J. LeBlanc Heating sizes the equipment to the house and how it is used today rather than applying one approach to every property.
