HVAC Indoor Air Quality Stuffy no more.
Fresh air is an important, and regulated, part of a building's indoor climate.
That's why an integral part of your HVAC system is ventilation. That number varies by area. Because of that, SCE urges you to check the current codes that specifically apply to your region. The ease of ventilation depends on your building. Most buildings today are equipped with adjustable ventilation dampers, ducts, and blowers that are easily adaptable to your building's fresh air needs.
