What is HVAC? HVAC stands for Heating Ventilation and Air Conditioning. The main purpose of a HVAC system is to help conserve excellent air quality, which is done through sufficient ventilation with filtration and thermal comfort. HVAC is important in the design of homes, medium and large industrial buildings and office buildings. Engineers design quality HVAC systems that is competitive with the cost of other more traditional ventilation designs, while also being successful in providing a proper quantity and quality of outdoor air and energy costs that are low and easier to maintain.

The HVAC design is based in ASHRAE data. The ASHRAE Standard 62.1-2010 is the national consensus standard for outside air ventilation. This standard is frequently included into state and local business codes, and gives specific instructions of the amount of outside air that must be maintained by mechanical and natural ventilation systems to may different areas.
A major design issue in construction that is not always in someone’s control is the control of climate and comfort. HVAC systems help with climate control and help keeps occupants of a building more comfortable by regulating the temperature and airflow. These systems are also important for the health of the occupants in a building because a properly controlled and maintained system keeps a building and home free from mold and other organisms that are harmful.
