"Avert Radon LLC , specifically Chance, recently completed radon mitigation work at my residence, installing two systems. I typically refrain from writing reviews, but felt compelled to share my experience with Avert Radon LLC . I'm extremely satisfied with the results, as the radon levels are now virtually undetectable. Chance demonstrated exceptional professionalism throughout the process. The communication was excellent, and their meticulous attention to detail was also outstanding. Furthermore, their post-installation follow-up has been consistently excellent. I highly recommend this company without reservation. They are among the best service providers I've encountered. if I could give it more than five stars, I certainly would!"

Radon Detection and Reduction questions, answered by experts

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.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. 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 action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

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’t hesitate to perform radon testing and install a mitigation system as soon as possible.

The cost to replace a radon fan ranges from $300 to $600 for the fan itself, with installation adding an additional $200 to $500. Overall, the total cost for replacement can range from $500 to $1,100, depending on factors such as the fan model, home size, and local labor rates. If the fan is part of a larger radon mitigation system, the price may be higher.

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.
