Q: Is a radon mitigation system expensive to run?

• <div><p>The fan that pulls the radon out of the air needs to run continuously, so you may see an increase in your electric bill once you install the mitigation system. Additionally, you may see an increase in your heating or cooling bills, as the fan can cause some loss of hot or cool air.</p></div>

Q: What if radon is still high after mitigation?

• <div><p>You'll need to test your home for radon after installing the mitigation system, then again every two years.

Q: What is the biggest source of radon?
