"Danny and his team is professional and helpful. We used a home monitor to check radon before the installation and once the fan is in, radon reading dropped below 1 immediately. Would recommend."

"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."

"We had a radon remediation installed by them in 2021. We've had to replace the fan 2x already- whereas the expected lifetime of a fan is 8-10 years."

"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."

As a real estate professional I know I'll need the services again and I know that he is the person I will be calling. Thank you!"
