We Know
Hollis Homes.
Hollis is one of Hillsborough County's more rural communities, covering about 32 square miles with roughly 8,300 residents at the 2020 census. Large lots, working farms, orchards, and conservation land shape the town. The Beaver Brook Association protects roughly 2,187 acres of forest, fields, and wetlands in Hollis and neighboring towns and maintains about 35 miles of public trails. A.J. LeBlanc Heating serves homes throughout that spread-out landscape.
Housing: Hollis was incorporated in 1746, and its housing spans nearly 300 years. The oldest properties date to the mid-1700s, and the Hollis Village Historic District around Monument Square is known for Georgian and Federal architecture. Older farmhouses and New England colonials line the rural roads, while many colonials, ranches, and custom homes were added during the 1970s and 1980s and again during the 1990s and 2000s. About 92 percent of the town's housing units are single-family homes, a similar share are owner-occupied, and lots tend to be large.
Furnaces, Boilers &
Heat Pumps
Heating in Hollis
Oil and propane are common heating fuels in Hollis, where natural gas service is limited. A.J. LeBlanc Heating repairs and replaces boilers and furnaces and helps homeowners compare their existing system with a cold-climate heat pump. Older farmhouses and colonials often have hot-water heat and no ductwork, making ductless equipment one option for adding both heating and cooling. We plan equipment, venting, piping, and electrical work carefully in older mechanical rooms where access and space may be limited.

Air Conditioning &
Mini Split Installation
Cooling in Hollis
Many older Hollis farmhouses and colonials were designed around boilers and were not built with ducts for central A/C. A mini split system can provide zoned cooling and supplemental heat with limited disruption to plaster and finished walls. Newer subdivision and custom homes with suitable forced-air ducts may be suited to central A/C or a ducted heat pump. A.J. LeBlanc Heating evaluates the home's layout, duct capacity, electrical service, and comfort needs before recommending either approach.
Cooling Services We Provide
We provide complete cooling service in Hollis for central air conditioners, heat pumps, and ductless mini splits. Our team has installed thousands of ductless systems across Southern NH. We respond quickly for both unexpected breakdowns and complete replacements.

Water Treatment in Hollis
Most Hollis homes use private wells. The Hollis School District operates a small regulated system for school and municipal facilities with limited residential service, and Merrimack Village District production wells in Hollis feed that utility's system. Neither creates a townwide residential network.
A.J. LeBlanc Heating bases its recommendation on private-well samples sent to an independent laboratory and selects equipment from the results. Treatment may combine sediment filtration with iron or manganese removal, use an oxidizing system for confirmed sulfur odor, or add a softener for measured hardness. For confirmed bacteria, ultraviolet treatment may be appropriate after correcting conditions that could interfere with disinfection.
Arsenic may be addressed with under-sink reverse osmosis or a whole-house arsenic system. When a well-water result confirms radon, we can refer the homeowner to an independent mitigation company.
Water Treatment Services We Provide
We install and service water-treatment systems for Hollis homes. When a private-well test is needed, we collect a sample and send it to an independent laboratory. We use the results to size anything from an under-sink drinking-water filter to a whole-house system.
- Well Water Filtration
- Water Softeners
- Iron & Manganese Removal
- Reverse Osmosis Drinking Water
