We Know
Exeter Homes.
Exeter is a historic Seacoast-adjacent town with deep roots. Phillips Exeter Academy defines a lot of the town's identity, and the surrounding neighborhoods have some of the most architecturally interesting homes we work in.
Housing: A wide range from 18th and 19th century homes near the academy and town center to 20th century residential streets and newer construction on the outskirts. The older homes are truly old and require experience to work in.
Heating: The older homes in Exeter often have steam or hot water systems that require real knowledge to work on properly. We see more original steam systems here than almost anywhere else in our service area.
Cooling: Mini splits are the right choice for the older historic homes. They add both heating and cooling without requiring changes that would damage original woodwork or plaster.
