HVAC, Plumbing & Electrical in Concord, NH

A capital city that runs old and new at once

Concord is the seat of state government and the heart of the Granite State, and its housing stock tells that whole story on one drive across town. You pass 1700s and 1800s homes through the downtown historic district and the South End, mid-century ranches on the hills above them, and new construction going up along the Merrimack. Downtown and the near neighborhoods pack older homes close together, while the outer wards spread into wooded lots and newer subdivisions, and each pattern brings its own demands. The city is stitched together by rivers - the Merrimack, the Contoocook, the Soucook, and the Turkey - and it sits on the granite bedrock that gave the state its name. This is inland New Hampshire, so there is no salt air to fight, but the cold, the rock, and the water table set the terms instead. Servicing a home here means knowing which era and which neighborhood you are standing in, because the right fix in a 1790 South End colonial is rarely the right fix in a new riverfront build.

Cold-climate heating built for a real Concord winter

Winter here is long and genuinely cold. January runs to average highs around 32 degrees and lows near 13, and the house is asked to hold heat for months, not weeks. That makes heating equipment the most important system in the building and sizing it the part that goes wrong most often. An undersized furnace or boiler never catches up on the coldest nights, and an oversized one short-cycles, wears itself out, and leaves rooms uneven. We size to a real load calculation and install right-sized furnaces, boilers, and cold-climate heat pumps rated to keep producing heat well below zero, with backup heat for the deepest snaps. For the many historic Concord homes that never had ductwork, ductless mini-split heat pumps deliver efficient heating and cooling without tearing the house apart, and they handle the humid stretch of summer that this river valley reliably gets.

Aging panels and standby power in historic homes

Concord's older homes were wired for a fraction of today's demand, and it shows up the moment you add a heat pump, central air, an EV charger, or a modern kitchen. Knob-and-tube wiring and 60 or 100 amp panels cannot safely carry that load, and undersized service can complicate both insurance and a sale. We upgrade to 200 amp service and rewire in stages so the house stays livable through the work. Power is the other half of the winter problem - an ice storm or a nor'easter can drop the lines for days, and when the heat and the well pump go with them a cold house is not far behind. A whole-home standby generator starts automatically, keeps the heat, water, and refrigerator running, and shuts down on its own when the utility returns.

Old pipes and the January freeze

Behind the plaster in a lot of these homes is galvanized or cast-iron plumbing that corrodes from the inside out, narrowing until the pressure drops at the tap and eventually failing behind a wall. We repipe in stages so the water stays on and the house stays livable. The cold brings its own risk - pipes that run through unheated crawl spaces, exterior walls, and old summer-built additions freeze and burst on the coldest nights, and the water damage almost never shows up where the ice actually formed. We find the lines most likely to freeze, protect or reroute them ahead of winter, and get to a burst fast when a hard snap gets ahead of everyone.

Hard water, wells, and radon in the rock

Concord's municipal water comes from Penacook Lake and runs hard enough to scale water heaters, clog fixtures, and leave spots on everything. A whole-home softener or filtration system and scheduled water heater flushing protect the equipment and clear the spotting. Homes in the outlying areas draw from private wells instead, and that raises a second issue the Granite State is known for - radon. New Hampshire's indoor radon averages several times the national number, and more than half of the state's groundwater is estimated to carry elevated radon, because the same granite bedrock under Concord releases it into both basements and well water. Iron and manganese are common in these wells too, staining fixtures and laundry, and we handle them in the same treatment pass. We test, treat the water where the radon comes up through the well, and build sealing and ventilation into the work so it is handled at the source rather than ignored.

Rivers, high water tables, and wet basements

All that river frontage comes with a high water table, and low-lying Concord basements take on water every wet spring and every heavy storm. A sump system sized for real volume keeps the basement dry, but a sump is only as good as the power behind it, and groundwater tends to peak during the exact storms that knock the electricity out. We install sumps built for storm volume, add battery or generator backup so the pump keeps running when the lines go down, keep the surrounding plumbing moving, and build the system for the wettest week of the year instead of an average one.

One team instead of five

The right-sized heating, the panel upgrade and generator, the repipe and freeze protection, the water treatment, and the sump are one licensed, veteran-owned team, not five contractors to chase and coordinate. You get one number to call, one crew that knows the house, and one guarantee standing behind the whole system rather than a stack of separate invoices and warranties. Our Manchester branch is a short drive down I-93, so same-day service in Concord is routine, we pull the permits and handle inspections, and every job is backed by our lifetime workmanship guarantee.
