Yes, free radon gas detectors, particularly those provided through state programs, can be reliable for initial screening. The Air Chek short-term tests commonly used are EPA-listed and have a proven track record of accuracy when used according to the instructions. It's important to follow the testing procedure carefully to ensure the most accurate results. For example, tests should be placed in the lowest lived-in level of the home, and windows and doors should be kept closed during the testing period. If you have concerns about the accuracy of a free test, you can also opt for a professional radon test conducted by a certified technician, which may provide more comprehensive data.
If your radon test reveals levels at or above the EPA action level of 4.0 pCi/L, it's essential to take action to protect your health. While this can be concerning, it's important to know that radon problems can be fixed. The first step is to confirm the initial result with a follow-up test, especially if it was a short-term test. If the follow-up test also shows elevated levels, you should contact a qualified radon mitigation professional. A professionally installed radon mitigation system can effectively reduce radon levels in your home and significantly lower your risk of lung cancer. In Ohio, we have a high prevalence of elevated radon levels, so effective mitigation is a common and important solution.
Finding high radon can be worrying, but there are good solutions. At Airduct Cleaning & Radon Co., we help people across Ohio, from Columbus to Cincinnati, Cleveland, and Dayton, make their homes safe. We know that radon problems in Ohio can vary. For example, the soil in some areas can make radon removal more complex. Also, houses here have different foundations. Because we understand these local issues, we design radon systems that work best for your specific home. Our goal is to give you clear answers, fast service, and peace of mind, knowing your family is protected.

The turnaround time for radon test results depends on the type of test you use. For short-term tests, you can generally expect to receive your results from the lab within 1 to 2 weeks after you mail the kit back using the provided prepaid envelope. Long-term tests, which are left in place for more than 90 days, will take longer to process. The lab analysis is a crucial step in the process, as it accurately measures the radon levels collected by the detector. Once the lab has completed the analysis, the results are typically sent to you via email or mail.
