Duncans Mills sits in the Russian River Valley, where coastal fog meets inland warmth, creating unique HVAC demands. Your system must handle cool, damp mornings and warmer afternoons, often within the same day. Many historic homes in the area lack modern ductwork, making ductless mini-split systems particularly popular. Proper humidity control is essential to prevent mold in this moisture-prone microclimate, especially during winter months.
