Q: How long can you go without a radon fan?

• <div><p>Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.</p></div>

Q: What are the risks of radon?

• <div><p>Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. 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: How long does the radon abatement process usually take?

• <div><p>Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.</p></div>

Q: What is considered a safe or dangerous level of radon?

• <div><p>No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.</p></div>
