We Know
Hollis Homes.
Hollis is one of the more rural towns in Hillsborough County. It covers about 32 square miles, with a population of around 8,300 at the 2020 census. Large lots, working farms, and apple orchards are what you see across Hollis, and much of the town is conservation land. The Beaver Brook Association alone protects roughly 2,187 acres of forest, fields, and wetlands across Hollis and its neighbors, with about 35 miles of public trails.
Housing: Hollis housing spans nearly 300 years. The town was incorporated in 1746, and its oldest homes date to the mid-1700s. The Hollis Village Historic District around Monument Square is known for its Georgian and Federal architecture. Out on the rural roads you'll also see older farmhouses and New England colonials. Most of the town's houses are much newer than those early homes, though. Close to a third of the homes went up in the 1970s and 1980s, and nearly as many between the 1990s and the 2000s. Colonials, ranches, and custom homes on subdivided land make up much of the town. About 92 percent of housing units are single-family homes, roughly the same share are owner-occupied, and the lots run large.
Furnaces, Boilers &
Heat Pumps
Heating in Hollis
Most of Hollis heats with oil. Natural gas service was never extended to much of this rural town, so a house that isn't heated with oil usually runs on propane. We do a lot of oil boiler and furnace work out here, repairs and replacements both, plus plenty of oil-to-heat-pump conversions as homeowners look to cut their fuel bills. The older farmhouses and colonials tend to have an oil boiler with baseboard or radiators and no ductwork, so a mini split or a boiler-to-heat-pump switch is usually the way to go. Utility rooms in these older homes are tight and dated, so we take our time getting the sizing and layout right.

Air Conditioning &
Mini Split Installation
Cooling in Hollis
Many older Hollis farmhouses and colonials were built around boilers and do not have ductwork for central air. Ductless mini splits can add cooling and supplemental heat with limited disruption to plaster and finished walls. Newer subdivision homes with suitable forced-air ductwork may support central A/C or a ducted heat pump. We evaluate duct capacity, electrical service, and the home's heating and cooling needs before recommending either option.
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.

Filtration, Softeners
& Testing
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. Those public supplies do not create a townwide residential system.
For a private well, laboratory results guide the equipment. We may combine sediment filtration with iron or manganese filtration, use an oxidizing system for a confirmed sulfur odor, or install a softener when hardness is measured. Confirmed bacteria may call for a whole-house ultraviolet system after correcting any water conditions that could interfere with ultraviolet disinfection.
Arsenic can be addressed with under-sink reverse osmosis or whole-house arsenic filtration. For a confirmed radon result, we can give the homeowner contact information for an independent mitigation provider.
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

Plumbing in Hollis
Most Hollis homes use private wells, so pressure, sediment, and treatment equipment are useful clues when a symptom reaches every fixture. They are not the cause of every plumbing complaint. We repair leaking pipes and faucets, toilets, shutoff valves, fixture connections, water heaters, and household drains.
When iron, hardness, or another tested condition is affecting plumbing performance, we can coordinate the treatment and repair while keeping the work focused on what your home actually needs.
