A ventilation system helps you manage the airflow in your home, circulating it through the use of ducts and fans, so you have air where and when you want it. Considering that the average American spends 90 percent of the day indoors, according to the Environmental Protection Agency (EPA), it is particularly important for a home to have good ventilation.
Regulation of Air
With the use of a ventilation system, you have more control over the airflow in your home. Without such a system, airflow would depend on the difference in pressure inside and outside your home.
During the winter, you may be exposed to too much fresh air, making you uncomfortable and raising your utility bills. During the summer, you will likely get too little fresh air.
And air could leak into your home from undesirable areas, such as from the garage.
Indoor air can be more polluted than outside air, according to the EPA's Energy Star initiative. A ventilation system can improve the quality of indoor air by getting rid of pollutants.
It also takes care of moisture that can lead to mold issues. A ventilation system also helps by filtering and conditioning the air from outside that enters your home.
According to the EPA, indoor air pollution and stale air can create health problems that include allergies, headaches, rashes and respiratory ailments, such as asthma and sinusitis. A good ventilation system protects against indoor pollutants, reducing the likelihood of these occurrences.
