We Know
Sandown Homes.
Sandown is a quiet community with lake and pond frontage that gives parts of it a distinct waterfront feel.
Housing: A mix of older rural homes, seasonal properties near the lakes, and newer single-family construction. Some of the lakefront homes here started as seasonal camps and have since been converted to year-round use, with all the mechanical implications that brings.
Heating: Oil and propane are the fuels here. The converted seasonal homes are a particular focus because they often have heating systems that were never designed for year-round use.
Cooling: Mini splits are ideal for the older and seasonal homes. Quiet, efficient, and they do not require invasive changes to the structure.
