Since then we have grown into one of the premier radon testing and mitigation companies in Ohio. Our President, Jim McDonald, and his staff have successfully reduced radon levels in over 10,000 homes in Ohio and West Virginia. Mr. McDonald is well regarded as an expert in his field and has received several awards and keynotes for his work. Throughout our success, we have always maintained a focus on customers’ health and well being. “One advantage of our systems is that we will custom design a system that not only is effective at reducing radon levels but will visually blend in with the architecture of your home.” –Jim McDonald A-Z Radon Services, LLC operates in both the residential and commercial fields.
