Radon Detection and Reduction questions, answered by experts

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.

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.

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.

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.

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.
