First, I want to thank you for the wealth of information I've gained from your channel. I have a finished basement(Atlanta GA), and to be honest, no one mentioned radon testing during construction. I could have done a better job sealing the floors and walls. I'm currently using two Airthings devices (Corentium and Wave Plus 2nd generation) placed side-by-side in the basement. They're showing a weekly average radon level of less than 4(3.8). When I turned off the basement's dedicated HVAC system, the radon reading dropped to 1.5. Additionally, opening a basement window further reduced the radon level. Considering these results, I'm thinking about installing an Energy Recovery Ventilator (ERV) for ongoing ventilation. What are your thoughts?
so it goes down when you open a window? seems like the radon leak would be away from the area of that window. When i open windows in my basement, my radon levels don't really change (i too am using the air waves).
Sounds like a negative pressure issue. I would install a ERV or HRV balancing the unit 60/40 (intake 60% / Exhaust 40%) to create slightly more positive air in house to make up for HVAC sucking in Radon looking for passive air intake.
I don't have any experience with HRVs or ERVs. I've heard they can be expensive to operate since you need to double your air changes per hour to cut your radon levels in half. One crucial aspect that many overlook is the regular maintenance of air exchanges. A clogged intake screen, for instance, can lead to increased radon levels. This is because the system, under such circumstances, would create more negative pressure in your home, drawing in more radon. If it were my house, I'd install a radon mitigation system and stop the radon from entering my home rather than trying to dilute it once it enters.
What’s the best way to mitigate radon in Florida condo with constant radon levels that are changing Every time the barometric pressure changes? my radon goes extremely up or down, depending on what it is.
