What is an HRV system?

 An HRV system provides an energy efficient way to bring in fresh filtered air while removing stale air. A heat recovery ventilator (HRV) brings in fresh air from the outside, preheats (using the existing warm air from inside) the incoming air during the winter and precools the incoming air during the summer.  It can provide clean fresh air every day while helping to keep energy costs low.The American Lung Association recommends HRVs and sealing of air leaks to protect your health while conserving energy.
