Upgrading Radon Mitigation Install with an ERV System

After another company installed a radon system last year for this homeowner, they still saw levels around 9 pCi/L in the basement and 5 pCi/L upstairs. Unsatisfied, he reached out to our team for a better solution. We installed an Energy Recovery Ventilator (ERV) on the back wall, using a Y-connection to also pressurize the crawlspace through the rim joist. The existing Festa Eagle Extreme and sealed sump were solid, but floor cracks and an inaccessible crawlspace limited performance. With the new ERV setup, the home now has better airflow, lower radon levels, and improved indoor air quality.
