My house's (builder-installed - so not my idea!) current solution is the most cost effective, IMO - you get the dampening of the cold make-up-air with lots of the benefit of an HRV (except it brings in cold air still, not nice, room temperature outside air like an HRV does)

So, cost effectiveness is definitely a big concern for me. Not sure I want to spend the $500+ for an HRV if there is a cheaper solution. When you say your builder-installed solution, were you talking about that damper valve attached to your cold air intake? Do you know where I could purchase one of those?
