The American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) has determined that today’s tightly sealed, energy-efficient Stockbridge, GA homes typically harbor high concentrations of contaminants due to poor ventilation. These toxins include radon, volatile organic compounds (VOCs), household cleaners, lead, pesticides and formaldehyde. Dust mites. pet dander, bacteria and viruses may also be present. Insufficient ventilation can also cause a moisture buildup indoors that encourages the growth of allergens. Learn more about ventilators here.

How Are Homes Ventilated?

Ventilation occurs naturally in homes without an airtight seal because small holes and cracks allow air to move in and out. Before the shift toward sealed homes to prevent energy losses, natural ventilation was enough to keep contaminants from overpowering indoor air. People also opened windows for fresh air. Now, people depend on their HVAC systems to maintain indoor comfort, and to counteract pollution, they are turning to mechanical, whole-house ventilation systems.

How Do Ventilators Work?

There are four types of mechanical ventilation systems: exhaust, supply, balanced and energy recovery. The most effective and efficient ventilation is provided by energy recovery ventilation systems. They move stale air outside and bring fresh air inside without losing heated and cooled air. Using a heat exchanger, whole-house ventilators use the heat that’s already inside a home to warm incoming cold air in winter. In summer, they use the cool air indoors to chill incoming warm air.

What Kind of Ventilation Systems Are Available?
