Mechanical ventilation is a critical component in the health of the home. If the HVAC system is analogous to a human heart, cooling or heating the home the same way blood can cool and heat the body, then ventilation is similar to the lungs of your home.
The best ventilation system can dilute or eliminate pollutants, control mold and mildew and filter air to remove unwanted particulates from a home. Good ventilation means providing good indoor air quality. A well-designed ventilation system also saves energy, controls moisture, and improves the durability of the home.
Pollutants stack up in places like bathrooms or basements, and can even hide out in wall cavities. Accumulation of pollutants results in hazardous health effects for the occupants, as well as structural damage to the building. As people spend more time in their homes, the rise in the rate of asthma and respiratory illnesses has also increased.
Unfortunately, indoor pollutants are virtually impossible to eliminate completely. Because of this fact, mechanical ventilation is necessary to guarantee good indoor air quality. Mechanical ventilation is used to remove any stale, moist, polluted air and replace it with fresh outside air.
