We Know
Mont Vernon Homes.

Mont Vernon is a small rural town in the Souhegan Valley of southern Hillsborough County. The village sits on a hilltop at about 820 feet, high ground between the Souhegan and Piscataquog watersheds. Old farms surround the village, including the town-owned Lamson Farm.

Housing: Around nine in ten of Mont Vernon's housing units are single-family homes, and roughly 96 percent are owner-occupied. Close to a quarter of the housing predates 1940. Older farmhouses and New England colonials sit next to smaller rural homes on big lots. Building picked back up from the 1990s into the 2000s, and the median home dates to about 1978.

By the late 1890s, Mont Vernon had become a summer-resort town with five large hotels, including the Grand Hotel atop Grand Hill. The resort trade faded with the Great Depression, and the hotels were gone by World War II. The town's Old Meetinghouse, built in 1781-82 and now the Town Hall, joined the National Register of Historic Places in 2024.

Heating in Mont Vernon

Most homes here run on oil. There is no natural gas line in Mont Vernon, so a house that is not on oil usually runs on propane or electric. A lot of what we do is oil boiler and furnace work in the older farmhouses and colonials. This work covers everything from annual tune-ups to full replacements and oil tank swaps. We are also getting steady interest in heat pumps, both as extra heat and as full oil-to-heat-pump conversions. Many older boiler-heated houses lack existing ductwork, so ductless mini splits are often the simplest option. A ducted retrofit may also work where installing new ducts is practical. Many of these older homes have tight utility rooms, so we size every system carefully.

Cooling

Air Conditioning &
Mini Split Installation

Cooling in Mont Vernon

Most homes in Mont Vernon were built long before central air conditioning was common, and many were never built with ductwork. Ductless mini splits are how people add cooling around here. They operate quietly and efficiently, and they do not change the look of an old farmhouse or colonial. Bigger homes usually use a multi-zone setup, with several indoor units, to reach the rooms that matter. On the newer builds that already have ductwork, we install and service central air too.

Cooling Services We Provide

We provide complete cooling service in Mont Vernon 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 and filtration by A.J. LeBlanc Heating in Mont Vernon, NH
Water Treatment

Filtration, Softeners
& Testing

Water Treatment in Mont Vernon

Mont Vernon homes use individual deep wells, individual shallow wells, and shared community wells. The town notes that iron, manganese, and hardness can cause staining, discoloration, scale, and poor soap performance in local well water. Those conditions are common, not universal, and a laboratory test shows what is happening at your property.

Iron and manganese filtration and softening for measured hardness are practical options when the results support them. Sediment prefiltration can protect the equipment installed after it. Separate findings may call for whole-house ultraviolet treatment, whole-house arsenic filtration or under-sink reverse osmosis, or an oxidizing system for confirmed sulfur odor.

When radon mitigation is appropriate, we can direct the homeowner to an independent company they can contact. Homes near a documented study area should follow the town's location-based testing guidance.

Water Treatment Services We Provide

We install and service water-treatment systems for Mont Vernon 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
  • UV Purification
  • Water Sampling & Independent Laboratory Testing

Water Heaters, Drains
& Fixtures

Plumbing in Mont Vernon

Iron, manganese, and hardness can leave staining or scale around Mont Vernon fixtures and water heaters, so treatment may help protect the plumbing when testing confirms those conditions. Mechanical problems still happen on their own. We repair leaking pipes and faucets, running toilets, worn valves, restricted supply lines, water heaters, and household drains.

By separating water-related wear from an ordinary component failure, we can recommend treatment when it adds value and keep straightforward repairs from becoming unnecessarily complicated.

Mont Vernon homeowners can call us for fixture repairs, water-heater work, household piping, drains, and service for well tanks and pressure switches. Our plumbers begin with a careful diagnosis.
