Rachel, Smaller rooftop units and split systems generally use the same refrigerant regardless of manufacturer, but higher capacity and custom application rooftop units can vary the refrigerant based on cooling application and compressor type. For this reason, it is best to perform the calculation for all the equipment specified in the design and to update the calculator when the equipment shop drawings are submitted. It is worth shopping around for small units to be able to compare pricing, efficiency, and refrigerant impact; however, small units are a commodity and there is limited ability for projects to be able to influence the specifications of equipment manufacturers.
