We Know
Sandown Homes.
Sandown started as a small rural town in Rockingham County and grew into a bedroom community as its population pushed past 6,500. A handful of small ponds give parts of town a waterfront feel, including Angle Pond down in the southeast corner.
Housing: Most of Sandown's housing consists of single-family homes, and they are largely owner-occupied. Most of these homes went up between the 1980s and the 2000s, and the median house dates to 1986. There is still an older core of pre-1940 homes, plus seasonal cottages near the ponds. Angle Pond has had a seasonal cottage community for a long time, and some of the older camps around the ponds have been converted to year-round living. These conversions can be tricky, because the camps started out as buildings that were never meant to hold heat through a full winter.
Furnaces, Boilers &
Heat Pumps
Heating in Sandown
Most of Sandown heats with oil, and propane comes in a distant second. Sandown has no natural gas service, so converting to gas is not an option. A lot of our work here involves replacing oil boilers and furnaces, along with oil-to-heat-pump conversions for homeowners who want to burn less oil. The converted camps near the ponds need extra care, because their heating equipment was often never built for a full winter. We take a hard look at what is actually in the house before we size anything.

Air Conditioning &
Mini Split Installation
Cooling in Sandown
Many of the older homes and converted camps have no ductwork, so mini splits are a practical way to cool them without tearing into the structure. Mini splits run quiet, they are efficient, and you can set up separate temperature zones room by room. The newer single-family homes already have forced warm air heat. Those homes can usually take central A/C using the existing ductwork. We size the cooling to the house instead of pushing one approach on everyone.
Cooling Services We Provide
We install and service central air conditioning, heat pumps, and ductless mini splits in Sandown. We have installed thousands of ductless systems across Southern NH. Whether you need a summer repair or a complete replacement, we respond quickly.

Filtration, Softeners
& Testing
Water Treatment in Sandown
Water service in Sandown depends on the address. Pennichuck East Utility and Hampstead Area Water Company each serve parts of town, while other homes have private wells. Public-water customers can use the report from their supplier and add household treatment only for a clear goal.
A whole-house activated-carbon filter or under-sink carbon or reverse osmosis system may fit a taste or drinking-water preference. Private-well homeowners should begin with accredited laboratory testing. Depending on the results, we can provide sediment filtration, a softener for measured hardness, or iron or manganese treatment.
Separate results may support whole-house ultraviolet treatment for confirmed bacteria or arsenic treatment through under-sink reverse osmosis or whole-house arsenic filtration.
Water Treatment Services We Provide
Sandown homeowners can call us for water-treatment installation and service. For a private well, an independent laboratory analyzes the sample before we select and size the treatment equipment.
- Well Water Filtration
- Water Softeners
- Iron & Manganese Removal
- Reverse Osmosis Drinking Water
- UV Purification
- Water Sampling & Independent Laboratory Testing
Water Heaters, Drains
& Fixtures
Plumbing in Sandown
Sandown homes may receive Pennichuck East water, Hampstead Area Water Company water, or private-well water. The source and any treatment equipment matter when the same symptom appears throughout the house. For everyday service, we repair leaking fixtures, toilets, shutoff valves, supply pipes, water heaters, and household drains.
A problem limited to one bathroom, appliance, or branch stays focused there. If filtration or water chemistry is contributing to broader wear, we explain that connection and include it in the options.

Trusted Since 1928.
Converted camps near Sandown's ponds often require careful evaluation because the structures and mechanical systems may have been modified over time. We inspect the existing heating needs, building layout, and equipment before recommending an oil-system replacement, heat-pump addition, or new cooling system. Year-round homes and former seasonal properties can require different approaches.
