We Know
Amherst Homes.
Amherst has large lots, good schools, and a historic village center that the town works hard to preserve.
Housing: A real mix. Older colonial and cape-style homes near the village green that date back generations, alongside larger newer construction from the 90s through today. Lot sizes here are generous.
Heating: Gas is available in a good portion of the town, but oil and propane heat are still common in the older and more rural areas. We install and service all three.
Cooling: Cold-climate mini splits are popular choices in Amherst. Multi-zone installs are a common project, especially in the larger custom homes.
