McQuayToolsâ„¢ for Engineers, a free software program, can help in sizing and selecting products that meet HVAC job requirements. It lets engineers choose from a variety of sizes, options, and components, as well as complete systems, including chillers, indoor air handlers, packaged rooftop units, self-contained units, coils, fancoils, and water-source heat pumps. The software also generates dimensional drawings and technical and performance data and can generate specifications and equipment schedules. The program is installed on the user's computer hard drive and accesses information on a secured network, or via the Internet. The program is updated quarterly.
