Ventilation is vital in all homes. Investigate these strategies for proper air quality maintenance: 1) No ventilation; this requires constant breezes or stable temperatures. 2) Natural ventilation, a non-mechanical option drawing air up and out of the house via vents and solar chimney. 3) Exhaust-only mechanical ventilation uses exhaust fans to remove stale air and moisture. 4) Supply-only ventilation, which uses a fan to bring in fresh air, and allows old air to pass through leaks in the house. 5) Balanced ventilation, a desirable option using separate fans to control airflow. 6) Balanced ventilation with heat recovery; this strategy places separate fans together with an air-to-air heat exchanger to precondition outdoor air.
