Single-Zone
One outdoor unit to one head for a cold room or an addition in a Walpole home with no ductwork.
Read moreWalpole — a river-valley town of historic, often pre-1940 homes where ductwork was never part of the original build. That makes ductless the natural fit: a head where you need it without tearing into plaster.
Walpole is heavy on pre-1940 single-family homes in the river valley, many never ducted. The work is mostly single-zone installs and additions, with larger homes occasionally going whole-house multi-zone. Line-set routing through older construction is the main planning variable.
Calls run heaviest in fall and early winter as owners plan around heating season, with steady interest from owners pairing a comfort fix with the efficiency rebate.
