Technicians include HVAC software in their toolbox. So do HVAC dealers and designers. With larger systems, you can find HVAC software that not only helps diagnose system problems but also helps with management. Software may provide tools to help with scheduling, dispatching, billing, maintenance and inventory.
HVAC engineers use design software to develop heating and cooling systems for new buildings based on their architecture and use. HVAC software enables building owners to see computerized simulations of poorly performing HVAC systems and new HVAC systems before installation.
