HVAC, Plumbing & Electrical in Antrim, NH

Three villages spread across thirty-six square miles

Antrim is three villages spread over thirty-six square miles of Hillsborough County hill country. Antrim Center sits at the geographic middle on Route 31, South Antrim became the commercial end of town along US Route 202, and North Branch sits where Routes 9 and 31 cross. The Contoocook forms the Bennington town line, Great Brook runs down the middle of town to meet it, and Bald Mountain rises 2,037 feet over Willard Pond in the west. A call here can be a brick mill-era house on Main Street or a camp road off Gregg Lake, and mechanically those two homes have nothing in common.

Cold-air hollows, oil tanks, and a long heating season

At Loverens Mill Cedar Swamp off Route 9 in North Branch, the hills funnel cold air into a hollow at 1,040 feet and hold it there, which is why a boreal cedar swamp survives this far south. The same drainage happens in every low pocket between Antrim's ridges, so two houses a mile apart face different design temperatures on the same January night. We size heating from a real load calculation for your address and elevation, because equipment that holds fine in Antrim Center comes up short in a hollow off Loveren Mill Road.

No natural gas main reaches Antrim, so heat here comes out of a tank or a woodpile. Most homes run oil-fired boilers or furnaces, propane covers much of the outlying construction, and plenty of houses off Route 31 still lean on a woodstove through the hardest week. The tank, the lines, and the venting are part of the system we maintain, and we service it before the season, since a no-heat call out toward Craig Road in January is a frozen-pipe problem.

Cold-climate heat pumps have changed the math up here. They hold usable output well below zero and pair with the oil or propane equipment you already own, so your boiler becomes backup for the few nights Antrim truly demands it.

Cooling houses that never had ductwork

The median Antrim home was built in 1938, and more than half of the town's houses went up before 1940. That is mill-era stock around Main Street and the Mill Pond, built for wood and radiators, with no duct chases behind the plaster and finishes worth protecting.

Ductless mini-splits solve it. A wall head and a small line set through an exterior wall give a Main Street mill house real cooling and dehumidification, zone by zone, with no duct retrofit. In the humidity that settles over the Contoocook valley in July, pulling moisture out matters as much as pulling heat out.

Mill Pond, Great Brook, and the plumbing under a mill village

More than twenty mills once ran between Gregg Lake and the point where Great Brook joins the Contoocook, and the Summer Street dam still holds back the Mill Pond alongside Main Street. The Goodell Company alone filled five adjoining brick buildings raised between 1867 and 1895 and employed most of the town for a century. The houses built for those workers are still lived in, and many still run their original galvanized and cast-iron plumbing.

That shows up as brown water, pressure that has dropped off fixture by fixture, and drains that back up on a schedule. Village properties on the municipal system out of Depot Street fail differently than outlying homes on wells and septic, and we work both. Stone-foundation cellars near the Mill Pond sit close to the water table, so a sump pump with a real backup is standard equipment on this side of town.

Wells drilled into Antrim granite

Outside the village water district, Antrim homes draw from bedrock wells drilled into New Hampshire granite, and that granite releases arsenic, radon, and uranium with no taste, smell, or color to warn anyone. NHDES estimates about a quarter of private wells statewide exceed the state's 5 parts per billion arsenic standard, and Hillsborough County ranks high-risk.

State guidance is bacteria and nitrate yearly, arsenic and radon every three to five years, a schedule almost no well owner keeps. We test first and build to the result: arsenic removal, radon aeration, softening for hardness, and iron and manganese filtration where the numbers call for it.

Panels built for 1938 loads

A house framed in 1938 on Main Street was wired for lights and a radio, not a heat pump, an induction range, a well pump, and a car in the driveway. In Antrim's older stock we routinely find 60 and 100 amp services, fuse panels, and cloth-wrapped or knob-and-tube runs still carrying live circuits behind original plaster and trim.

We upgrade those services to 200 amps, replace failing wiring with routing that respects the woodwork instead of gutting it, and add the dedicated circuits an Antrim household actually draws today, EV charging included, with permits pulled through the town and inspected.

When ice takes down the lines out on Route 9

Antrim's power arrives on overhead lines strung through miles of wooded road. The December 2008 ice storm knocked out 211 of New Hampshire's 256 communities and left some customers dark for two weeks. Antrim now hosts nine wind turbines along the Tuttle Hill ridgeline, and none of that generation reaches your house when the line down your own road is under a fallen limb.

A propane standby generator starts itself when the utility drops and keeps the heat, the well pump, the septic pump, and the freezer running. On a well, an outage is not just a dark house, it is a house with no running water.

One call instead of five

The right-sized boiler, the mini-split, the well treatment, the 200 amp service, and the standby generator all come from one licensed, veteran-owned team out of our Manchester branch at 201 Allard Drive, not five contractors to chase down. Same-day service where the day allows, permits pulled and inspections handled with the town, and a lifetime workmanship guarantee behind everything we install.
