We Know
Amherst Homes.
Amherst is known for its generous lots and a carefully guarded historic center. A Historic District Commission oversees the village around the common. The old center keeps its look while the newer neighborhoods spread out on big lots around it.
Housing: About 93 percent of Amherst's housing units are single-family homes, and just about the same share are owner-occupied. Most of these homes sit on good-sized lots. Near the common you'll find older colonial and cape-style homes, some going back generations. The 1970s and 1980s were the busy building years and account for roughly 44 percent of the houses in town. The remaining homes mostly went up from the 1990s on, and the median home dates to around 1978.
Furnaces, Boilers &
Heat Pumps
Heating in Amherst
Liberty Utilities runs natural gas to part of town. Plenty of homes in the older and more rural areas still heat with oil or propane, and we install and service all three. A lot of those houses date back to the peak building years, so we stay busy swapping out aging oil and propane boilers and furnaces. Where a natural gas main runs along the street, we'll also do oil-to-gas conversions. In the older village homes on hot-water heat, we handle boiler swaps and the piping around them. In neighborhoods without natural gas service, a propane or high-efficiency oil system is still the way to go.

Air Conditioning &
Mini Split Installation
Cooling in Amherst
We install a lot of cold-climate mini splits in Amherst, and multi-zone jobs are common in the bigger custom homes. Plenty of the older village houses were built around hot-water heat and never had ductwork. A ductless heat pump adds real cooling to those homes without tearing into finished walls. If a house already has forced-air, we'll fit central A/C or a ducted heat pump instead. Either way, we size each zone to its room so nothing ends up over- or under-cooled.
Cooling Services We Provide
We install, repair, and service all types of cooling equipment in Amherst, including central air, heat pumps, and ductless mini splits. With thousands of ductless installations completed across Southern NH, our team has extensive experience. We respond quickly when you need a repair or replacement.

Water Treatment in Amherst
Amherst has many private wells along with limited public-water service. Documented work involving PFAS (per- and polyfluoroalkyl substances), a family of long-lasting chemicals, has included investigations and public-water extensions in defined areas near Cobbler Lane and Thatcher Drive. Those local response areas do not describe every Amherst well.
If your home has a private well, we use a current laboratory panel and add PFAS testing when the location or state guidance supports it. Treatment may include sediment filtration, iron or manganese filtration, a softener for measured hardness, sulfur-odor treatment, whole-house ultraviolet treatment for confirmed bacteria, or arsenic treatment selected for the laboratory result. Any PFAS result needs equipment chosen for that contaminant with verified performance.
Public-water customers can consider activated carbon or a dedicated drinking-water system for a specific goal at the tap.
Water Treatment Services We Provide
Our team installs and services water-treatment equipment for Amherst homes. We use independent laboratory results for private wells and the utility report and condition at the tap for public-water homes.

Water Heaters, Drains
& Fixtures
Plumbing in Amherst
Amherst's private wells and public-water extensions give homes different supply and treatment arrangements. When sediment, hardness, or pressure is affecting fixtures throughout the property, we look at that connection. Most plumbing repairs are still specific to the home, including leaking faucets and pipes, toilets that will not stop running, failed shutoff valves, poor hot-water delivery, and recurring drain trouble.
We identify the cause, explain the options, and keep treatment recommendations limited to situations where the water is contributing to the problem.

From everyday plumbing repairs to water-heater and well-tank service, we help homeowners throughout Amherst. We also service pressure switches and related well-system controls.

Local to Amherst.
Trusted Since 1928.
We take the time to walk Amherst homeowners through the options and the tradeoffs, so you're never guessing. In the village historic district, we plan equipment placement with the home's historic character in mind. The bigger custom homes often need multi-zone systems, and we size every install around what the house actually calls for. A lot of the equipment around here is well past its prime, so a good share of our work is swapping out aging boilers, furnaces, and AC for the right-sized replacement.
