4 Ton Packaged Straight Cool Units, built for cooling larger homes, offices, or light commercial spaces between approximately 2,100 and 2,400 square feet. These all-in-one HVAC systems house the compressor, condenser, and air handler together in a single outdoor cabinet, saving valuable indoor space. Unlike traditional split systems that separate components inside and outside the building, packaged straight cool units are ideal for rooftops, garages, manufactured homes, and commercial installations. Focused strictly on cooling, they are perfect for warm climates where heating is not a priority. Includes choice of backup electric heat strip for heating. Family owned and operated for over 30 years, we offer fast shipping, free duct designs with every system purchase, transparent pricing, and expert warranty and customer support.
