A farm town on the east bank of the Merrimack

Litchfield runs long and narrow up the east bank of the Merrimack River, Merrimack and Nashua across the water, Manchester at the north end of Route 3A. Granted as Brenton's Farm in 1729 and renamed in 1749, it stayed farmland for two centuries: alluvial soil, no town common, no downtown, everything strung along what is now Charles Bancroft Highway, where McQuesten's farm stand and Nesenkeag Co-op Farm still work it.

The 1970s changed that. Nashua and Manchester pushed housing into the north and south ends, and the town cut Albuquerque Avenue to steer growth off Route 3A and away from the best fields. The result is roughly 2,900 homes, median build year around 1987, sitting on sand and gravel beside a river.

A town whose furnaces all aged out together

Litchfield is a commuting town, so houses sit cold all day and recover hard at night, and the valley floor holds cold air into a January morning. Fuel is split: Liberty runs natural gas up parts of the Merrimack valley corridor, while plenty of homes off Albuquerque Avenue and Page Road burn oil or propane.

The real issue is timing. A town built in one twenty year stretch gets its furnaces and air handlers wearing out in that same stretch, and we replace original equipment on whole Litchfield streets within a few seasons. We size to a load calculation rather than the sticker on the old unit, and check ductwork while the equipment is out, because an undersized return in a raised ranch chokes a new furnace the way it choked the old one.

Summer humidity on the valley floor

Low ground beside the Merrimack gets the muggy end of a New Hampshire summer, and humidity is where air conditioning goes wrong. An oversized condenser cools a Litchfield colonial fast, shuts off before it pulls the moisture out, and leaves a clammy house and a damp basement. We size to the real load so the system runs longer cycles that actually dehumidify.

Then there is the room that never gets comfortable: the bonus room over the garage in a 1990s colonial, or the addition on a Route 3A farmhouse that was never tied into the trunk line. Ductless mini-splits solve both without opening walls.

Well water, the PFOA line, and what the granite adds

Litchfield's drinking water is really two towns. After PFOA turned up at or above 70 parts per trillion in private wells here, Pennichuck extended the public system and connected more than 360 Litchfield homes by late 2018, treating water drawn from the Merrimack River and Pennichuck Brook. Everyone outside that footprint is still on a private well into the sand and gravel or the bedrock beneath.

On a well, New Hampshire granite is what you test for. Arsenic, uranium, radon and manganese come out of that rock naturally, about one in five private wells statewide runs high on arsenic, and none of it can be tasted or smelled. We test before recommending treatment. On the Pennichuck side the complaint is different: chlorine taste and the wear chlorinated water puts on fixtures and water heaters, which calls for carbon filtration, not a softener.

Sand, a high water table, and a town on septic

The largest floodplain on the lower Merrimack sits in Litchfield, and the ground here is stratified drift, sand and gravel dropped by glacial meltwater. It drains fast and carries a lot of water, which is why Litchfield's health rules require a septic bed to stay three feet above the highest known water table, and why basements on the low ground east of Route 3A take on water in a wet spring.

There is no municipal sewer here, so every home runs its own septic into sandy ground, and disposals, back-to-back laundry and a softener discharging to the tank all shorten a leach field. We install sumps sized for real storm volume with battery backup, set ejector pumps for below-grade baths, and replace polybutylene supply lines common in homes built between 1978 and 1995.

Panels sized for a 1985 house

The homes around Darrah Pond went up in the mid-1970s and the north and south end subdivisions followed through the 1980s, each with a panel sized for one oven, one dryer and window units. Nobody wired those houses for a heat pump, a well pump and two cars charging in the driveway, and in a town where 98 percent of residents drive to work, the EV charger request is usually what reveals the panel is full.

We upgrade services to 200 amps, replace the failed breakers and corroded meter sockets that turn up on forty year old equipment, run dedicated circuits for heat pumps and chargers, and wire a generator interlock, permitted and inspected.

When the ice comes down along Route 3A

The December 2008 storm laid a half inch to over an inch of ice across southern New Hampshire and left parts of the region dark for more than a week. Litchfield's power runs overhead down Charles Bancroft Highway and back through wooded subdivision streets, and those tree lines are what bring the wires down.

An outage costs more here than in a city. A Litchfield home on a private well and septic loses its water, its ability to flush and its heat the moment the power drops. A properly sized standby generator starts on its own, carries the furnace, the well pump, the septic pump and the sump, and shuts down when the utility restores the line.

One call instead of five

The furnace replacement, the mini-split, the arsenic test and treatment, the sump and septic pumps, the 200-amp upgrade and the generator are one licensed, veteran-owned team out of our Manchester branch on Allard Drive, a short run up Route 3A, not five contractors to schedule and chase. Same-day service where we can get it, permits pulled, inspections handled, and a lifetime workmanship guarantee behind all of it.

Our own research, sourced and dated, on the problems that come up around here.

• What's Really In Your Tap Water (And What You Can Do About It)Your municipal treatment plant was built to solve 20th-century problems. The list of things that end up in the water supply has changed a lot since then. Here is what the research actually says, and what you can do about it at your own house.
• PFAS: The Forever Chemicals In Your WaterNearly half of U.S. tap water contains PFAS, the federal deadline just moved to 2031, and four of the six regulated compounds are proposed for rescission. Here is what that actually means in New Hampshire, Maine and New Jersey - and what removes them.
• Chlorine Byproducts: When the Cure Creates the ProblemChlorination is one of the great public health achievements of the last century and I am not going to argue against it. But the chlorine reacts with organic matter in the water and makes something else - and your hot shower is a bigger exposure route than your drinking glass.
• Microplastics: What We Know and What We Do NotMicroplastics are in tap water, bottled water, food, air, and human blood and placental tissue. The WHO says current levels do not appear to pose a health risk. Both of those statements are true. Here is how to hold them at the same time.
