In summer HRV’s work in reverse, retaining cooler air conditioned air and transferring to incoming fresh air. [NOTE: As defined by AHR standards, only areas of the SouthEast U.S. subject to significant outdoor humidity for extended periods throughout the year should consider an ERV. Many Lifebreath ERV models are available for this region.
