With the cold temperatures of winter descending upon most areas of the United States, there is a desire to keep as much heat as possible in the home. Ventilation systems can sometimes make it difficult to retain the heat in the home, as the warmed air is cycled out and the cold air is cycled in. This can spike electric and gas bills and affect the comfort level of the home. Humidity levels may also be difficult to control, resulting in dry skin and breathing discomfort.
