"Schan did a great job, very professional. He came out to see what the job was before he gave me a quote. I have a huge crawl space which took some time but he stuck with it to finish it in one day. Now I can breathe easier knowing it's taking care of right. I highly recommend Clean Air Radon Systems."

"This business was highly recommended by my realtor. I hired this company to inspect the radon mitigation system prior to me buying a house. The owner, Sidad, was very responsive to my inquiries. The inspection price was reasonable, and he followed up promptly with the results on the inspection. I hired him to come out and fix the radon mitigation fan after purchasing my house. He was quick and efficient, and the price was reasonable. I highly recommend this business."
