HVAC stands for heating, ventilation, and air conditioning. In computing and especially in enterprise centers, factory and residents HVAC systems control the ambient environment (temperature, humidity, air flow, and air filtering) and must be planned for and operated along with other data center components such as computing hardware, cabling, data storage, fire protection, physical security systems and power. The selection of an HVAC contractor is an important step in planning for the most comfortable working and living environment.
