First and foremost, HVAC stands for heating, ventilation, and air conditioning. This system provides heating and cooling to residential and commercial buildings. You can find HVAC systems anywhere from single-family homes to submarines where they provide the means for environmental comfort. Becoming more and more popular in new construction, these systems use fresh air from outdoors to provide high indoor air quality. The V in HVAC, or ventilation, is the process of replacing or exchanging air within a space. This provides a better quality of air indoors and involves the removal of moisture, smoke, odors, heat, dust, airborne bacteria, carbon dioxide, and other gases as well as temperature control and oxygen replenishment.
Air quality standards are designed to protect the population. They ensure that people have clean air to breathe.

When a state fails to meet air quality standards, it can face penalties such as loss of federal funding, increased regulatory oversight, and requirements to implement stricter pollution control measures. This failure can also lead to negative health impacts on residents due to increased levels of pollution in the air. States may be required to develop and implement plans to improve air quality and come into compliance with the standards.
