HVAC, Plumbing & Electrical in Amherst, NH

An old inland town on granite, and it shapes every system in the house

Amherst sits along the Souhegan River in the Merrimack watershed, on the same granite bedrock as the rest of southern New Hampshire, with the historic Village Green at its center and large-lot homes, private wells, and the shoreline of Baboosic Lake spread out around it. It is a beautiful place to own a home and a demanding one to keep running, because a real inland winter, humid summers, and water drawn straight from the rock all pull on the systems inside the house at once. There is no salt air here to worry about, but there is plenty else, and servicing a home in Amherst means building every system for that reality. It starts with the houses themselves.

Historic homes and the wiring behind the plaster

The Village Historic District is one of the best-preserved late-eighteenth and early-nineteenth century village centers in the state, and much of Amherst's housing stock is genuinely old, Georgian, Federal, and Greek Revival homes built long before modern electrical loads existed. Those houses often still carry undersized panels, and some hold original knob-and-tube wiring that was never meant to run a kitchen full of appliances, central air, and a car charger. Left alone it becomes a safety and capacity problem. We upgrade panels and rewire these homes with routes and methods chosen to protect plaster, trim, and finish, so the house is safe and modern without losing what makes it worth owning. The same care goes into the old galvanized and cast-iron supply lines that corrode and choke off pressure over the decades, which we repipe in stages rather than tearing the place apart.

Heating built for a real New Hampshire winter

January in Amherst runs cold, with lows in the teens and better than four feet of snow across a typical season, so heating is not a comfort question here, it is a keep-the-house-safe question. An undersized or failing system in a January cold snap puts both the family and the plumbing at risk. We size heating to a real heat-loss calculation instead of a rule of thumb, because a system that is guessed at either falls behind on the coldest nights or short-cycles itself to an early grave. For the many older Amherst homes that never had ductwork, cold-climate ductless mini-split heat pumps are the answer, delivering efficient heating and cooling room by room without forcing ducts through a historic house, and we pair them with backup heat so the home stays warm through the hardest stretch of the winter.

Humid summers and cooling that actually dries the air

Amherst summers climb into the eighties and carry heavy humidity, and that humidity is what makes cooling tricky. An oversized air conditioner cools the air quickly but never runs long enough to wring the moisture out, leaving the house cool and clammy and, on a wooded lot with a damp basement, prone to mold. Sizing is everything. We size cooling to the same real load calculation we use for heat, set up proper dehumidification, and, where a heat pump is doing the work, tune it to both cool and dry the air through the muggy stretch of July and August. The result is a house that feels dry at seventy-two, not merely cold.

Private wells, and why the water is a treatment question

Much of Amherst draws its water from private drilled wells reaching into granite bedrock, and that rock gives the water its character. Across New Hampshire roughly one private well in four exceeds the state's arsenic standard, radon released by uranium in the granite dissolves into groundwater, parts of Amherst have tested for PFAS, and on top of all of it the water runs hard and heavy with iron and manganese that stain fixtures and scale up pipes and water heaters. None of this shows up in the taste, which is exactly why it gets missed. We test the full panel, arsenic, radon, PFAS, hardness, iron, and manganese, then build the treatment the water actually needs rather than selling a softener and calling it done. Hard water solved at the source is a water heater and a set of fixtures that last years longer.

Frozen pipes, wet basements, and the homes around Baboosic Lake

Two water problems bracket the Amherst winter. In the older and seasonal homes, pipes run through uninsulated walls and crawlspaces that were fine in summer and freeze solid in a January cold snap, so we insulate, reroute, and freeze-protect the vulnerable lines before the cold arrives instead of after one bursts. At the other end, the homes around Baboosic Lake and the low ground near the brooks sit on high water tables, and their basements take on water through the spring melt and heavy rain. We install sump systems sized for real volume with battery or generator backup, because the groundwater peaks in the same storms that knock the power out. For the lake homes that were built as seasonal cottages and are now lived in year-round, we handle the winterizing and the freeze protection that keep them livable in the dead of winter.

Whole-home power for a well and a wooded town

Outages in a wooded New Hampshire town come with every big storm, and on a private well an outage means no water at all, no heat circulation, and a sump that stops just when it is needed most. A whole-home standby generator keeps the well pump, the heat, the sump, and the refrigerator running through a multi-day outage, starting on its own and shutting down when the utility returns. It is one of the most requested installs we do out here, and it pairs naturally with the panel upgrades that modern Amherst homes are asking for anyway, for pools, workshops, and EV chargers.

One call instead of five

The panel upgrade, the mini-split, the well treatment, the frozen line, the sump, and the generator are one licensed, veteran-owned team out of our Manchester branch minutes up the road, not five contractors to line up and coordinate. Same-day service where we can, permits pulled and inspections handled, and a lifetime workmanship guarantee behind all of it.
