Here are some pictures of various projects we have worked on since 2004.  We have retrofitted HRV's in hundreds of houses, and have figured out how to minimize the impact on your house and your life.  We can install a HRV in any house. 

About the Images

Many older houses are being weatherized to make them more efficient.  A crucial part of the upgrade is to provied proper mechanical ventilation to prevent damage to the house from condensation and high humidity levels in the house. 

With lots of careful measuring, it is possible to retrofit an HRV into most homes with minimal impact on the existing structure. 

Many of the ducts can be hidden in the crawlspace, the backs of closets, or other inconspicous locations.  Other times the ductwork may require a soffit built across some rooms to hide the ductwork.
