ERVs (Energy Recovery Ventilators) are popular for improving indoor air. When it comes to crawlspaces, they can do more harm than good when used to dry a crawlspace out. In this episode, I explain why using an ERV to dry a crawlspace is a flawed strategy that can make moisture and mold problems worse — and what you might do instead.

You'll learn:

• Why ERVs can introduce humidity instead of removing it
• The science behind moisture control in unconditioned spaces
• Smarter strategies for drying crawlspaces (that actually work)

Crawlspace issues can be complex. If you've got questions, schedule a consult:
