Q: Why is my radon mitigation system so loud?

• <div><p>Your radon mitigation system may be loud because it&rsquo;s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.</p></div>

Q: How is radon gas abatement professionally handled?

• <div><p>Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.</p></div>

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. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.</p></div>

Q: Can you remediate radon yourself?

• <div><p>There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.</p></div>

Radon Detection and Reduction questions, answered by experts

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.

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.

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system.
