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.
Furnaces, Boilers &
Heat Pumps
Heating in Sandown
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.

Air Conditioning &
Mini Split Installation
Cooling in Sandown
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.
Cooling Services We Provide
We install and service central air conditioning, heat pumps, and ductless mini splits in Sandown. We have installed thousands of ductless systems across Southern NH. Whether you need a summer repair or a complete replacement, we respond quickly.

Water Treatment in Sandown
Water service in Sandown depends on the address. Pennichuck East Utility and Hampstead Area Water Company each serve parts of town, while other homes use private wells. Public-water customers can begin with their supplier's report and choose whole-house activated carbon or an under-sink carbon or reverse osmosis system for a specific taste, odor, or drinking-water goal.
A.J. LeBlanc Heating starts with private-well samples collected for an independent laboratory and uses the results to select sediment, hardness, iron, manganese, ultraviolet, or arsenic treatment. Each system is matched to the water and household demand at that property.
Water Treatment Services We Provide
Sandown homeowners can call us for water-treatment installation and service. For a private well, an independent laboratory analyzes the sample before we select and size the treatment equipment.

- Water Softeners
- Iron & Manganese Removal
- Reverse Osmosis Drinking Water
- UV Purification

Trusted Since 1928.
Converted cottages near Sandown's ponds require careful evaluation because their structures and mechanical systems may have changed over time. A.J.
