HVAC and Roofing in Frontenac, MO

Mini split (ductless) systems are an increasingly popular choice for homes and small commercial spaces in Frontenac, MO. These systems provide zoned comfort, high efficiency, and minimal disruption during installation. For older homes, renovations, or additions, a ductless mini-split often delivers better temperature control and lower energy use compared to extending or installing new ductwork. At Sheet Metal Contractors, Inc., we bring the design expertise, sheet metal coordination, and technical skills necessary to ensure reliable, long-term performance in the St. Louis climate.
