Q: Is it okay to live in a house with radon?

Q: What are the risks of radon?

If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don&rsquo;t hesitate to perform radon testing and install a mitigation system as soon as possible.</p></div>

Q: How often should you replace a radon fan?

• <div><p>Many radon fans carry a five-year manufacturer's warranty. That said, your radon fan should last between five and ten years. Regular inspections will ensure the fan is operating properly. Unusual or exceptional noise coming from the fan or indications on your manometer or system monitor can immediately tell you that something is amiss.</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>
