Mini-Split AC Installation and Ductless Cooling in Old Greenwich
Nestled along the Connecticut coastline, Old Greenwich seamlessly combines classic New England charm with a coastal lifestyle. As any long-time resident or architect will agree, the architecture in Old Greenwich is as diverse as its seasonal climate. Colonial homes, coastal cottages, and modern custom builds line the streets, often requiring flexible cooling solutions to maintain comfort year-round.
With hot, humid summers and freezing winters, efficient heating and cooling systems are a must. However, traditional HVAC systems pose challenges to many historic or custom-built homes due to ductwork constraints, layout limitations, and efficiency concerns.
