In Iowa, this client's family faced indoor air quality issues despite efforts to maintain comfort since they moved in the home. Learning about ERV benefits from Iowa Radon Defense, they sought expert help. Identifying poor ventilation as the root cause, the team proposed an ERV solution. The clients eagerly agreed, and the system was installed by the team, effectively exchanging stale indoor air with fresh outdoor air. Thanks to Iowa Radon Defense's prompt service, they bid farewell to ventilation problems, enjoying a comfortable and healthy home environment. 

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.

ERV Installation in Old Farmhouse With Radon Levels of 7 and No HVAC System

This old farmhouse tested at 7 pCi/L, with multiple basement chambers and a large cistern, making airflow and radon control more complex. With no furnace or ductwork and only a boiler, improving indoor air quality required a different approach. An ERV system was installed along the west wall to bring in fresh air and reduce radon buildup. One vent exits through the rim joist at the front of the home, while the second will be cored through the foundation for proper airflow balance. This setup supports steady ventilation and helps lower radon levels in a structure without traditional HVAC.

Protecting Family Health with Radon Mitigation

Tim and Shelly have faced serious health challenges; both were diagnosed with cancer in recent years. Concerned about the dangers of radon exposure, they wanted to protect their children and grandchildren from future cancer risks. That’s when they turned to a professional radon mitigation system.

Our team installed a two-point radon mitigation system on the south side of their home. One extraction point was placed behind the garage near the foundation wall, while a second point was added under the crawl space, ensuring radon gases were effectively pulled away from living areas. We also sealed around the sump lid in the basement and installed a 16x25 BEZ filter to improve indoor air quality. They had a ERV insalled for better indoor air.

While the slab condition meant we could not guarantee exact levels, this system provides powerful protection. For Tim and Shelly, reducing radon was an essential step in safeguarding their family’s health for generations.

It was a bachelor's home and since the client uses it as his office too, he was wondering if the indoor air quality is safe to breathe in on a regular basis. He had his home tested for radon and turned out he had high levels. He booked in for an installation and wanted to make sure that it does not disrupt the aesthetic look of his home. We guaranteed him that.
