Ground-Mounted Commercial HVAC Package Units

While residential air conditioning systems typically rely on a "split" design—meaning there is an outdoor condenser paired with a separate indoor blower in the attic or closet—commercial buildings often require a much more robust, consolidated approach. The industrial-grade equipment pictured above is a massive Carrier WeatherMaker package unit. As the name implies, an HVAC package unit combines the high-voltage compressor, the condenser fan, the evaporator coil, and the massive blower motor all securely within a single, heavy-gauge steel cabinet.

While most package units are famously hoisted onto flat commercial rooftops via helicopter or crane, many commercial or agricultural locations do not have the structural roof rating to support the immense weight. In these scenarios, the package unit is ground-mounted on a dedicated, reinforced concrete pad. As you can see terminating out the left side of the cabinet, thick, heavily insulated sheet metal ductwork acts as an umbilical cord, penetrating directly through the exterior wall to relentlessly pump thousands of cubic feet of cold air into the open commercial retail or warehouse space inside.

Ground-mounting large package units offers tremendous logistical advantages when it comes to long-term serviceability. Without requiring technicians to drag ladders and heavy refrigerant tanks up onto a sweltering roof, preventative maintenance—such as rapidly swapping out massive commercial air filters and chemically cleaning the aluminum condenser coils—can be executed significantly faster. SunDollar A/C & Heat specializes in these heavy-duty installations, ensuring your retail or industrial facility maintains absolute climate control despite the relentless heat index outside.
