Custom Comfort Heating and Cooling serves homeowners and property managers across Sonoma, Marin, Napa, Lake, and Mendocino counties. We handle heating and air conditioning installation, repair, and routine maintenance. Our work covers Santa Rosa, Bodega Bay, Ukiah, and surrounding communities. We are a veteran owned and operated business. Our goal is honest work, fast response, and fair pricing. Each job starts with a clear explanation of what your system needs. You decide the next step. We also work on ductless mini-split systems and ducted heat pump systems. Ductless systems cool and heat one room or zone without major duct work.
