The Global Leader in Residential Indoor Air Quality

The vänEE story begins in 1980 with Rick Olmstead founding Conservation Energy Systems Inc. However, the origins of the vänEE product start with the energy crisis of the early 1970s that created concerns about energy security in North America.

Those concerns led to the research and development of the first super-insulated homes and an appreciation for the indoor air quality issues created as we built homes with significantly less air leakage. Traditionally, houses are dry during winter due to excessive air leakage, so humidification is required for comfort and health. Once air-sealed, homes retain moisture and unhealthy contaminants, making controlled ventilation for the occupants' health and the building's security a necessity.
