Ventilation, (the “V” in HVAC) is the process of exchanging or replacing air in any space to provide high indoor air quality which involves temperature control, oxygen replenishment, and removal of moisture, odors, smoke, heat, dust, airborne bacteria, carbon dioxide, and other gases. Ventilation adds the proper amount of fresh air from outside to the indoor air in your home.

According to the American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE), ventilation is one of the most important jobs of an HVAC system. Why? Because without it, in the best case your space lacks fresh air and becomes stagnant and uncomfortable. In the worst case, you can be trapping in toxins and contaminants that can make people sick.

Without enough ventilation in your home, you will eventually experience some comfort issues and even health problems.

Your HVAC system is one of the most important systems in your home, it is also complicated. That is what makes it one of the least understood systems in the home as well.
