"They contacted us immediately and were here the next day to test our home for radon. They were very thorough and inspired confidence. They also gave us a report of what they found. Also resonable prices!"

"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."

"Mat is the inspector realtors hate... tongue-in-cheek. He is extremely knowledgeable, has great attention to detail, and is very honest. If there is something wrong with the property, you better believe he's going to find it. He takes the time and does a thorough job. I highly recommend him!"

"I had been working with another radon mitigation company. The owner seemed knowledgeable, but after coming to the house for the estimate he ghosted me. So I called Professional Radon Systems. They were wonderful to work with. They arrived at the scheduled time, told me what needed to be done, and made an appointment to do it. Two fantastic young men showed up when they said they would, did the work, explained everything, and that was that. Great company! I appreciate the professionalism and the high quality work."

"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."
