Shop Packaged Gas Units—powerful all-in-one heating and cooling systems that use natural gas or propane (LP) for heating. These systems combine the compressor, condenser, and gas furnace into a single outdoor cabinet, freeing up valuable indoor space. In cooling mode, the system works like a standard air conditioner, removing heat from inside your home. In heating mode, the gas furnace takes over to provide strong, reliable heat during colder months. Packaged gas units are ideal for rooftops, garages, manufactured homes, and light commercial properties where natural gas or propane service is available. As a family owned business for over 30 years, we offer fast shipping, free duct designs with every system, clear honest pricing, and expert warranty and technical support.
