I am not being hyperbolic when I say that this is the best company I have ever worked with for…read moreanything, ever. We tested for radon and though the level was not above 4.0 where the EPA would highly suggest (and probably enforce if they could) that a radon mitigation system be installed, it was reaching levels of 3.5 with overall averages of 2.5-2.7 and never going below 1.7 and this during the summer where radon levels measure lower than they do in winter months. Because there is no absolute safe level of radon exposure, and because we have an in-law living space in the basement where small children also spend a lot of time (their little developing lungs are even more vulnerable to radon exposure damage), we decided to get professional advice and were leaning toward installation of a reduction system. I tried reaching a company closer to our location, left several messages because they did not answer their calls, and sent a request for help on their website and no one ever contacted me. Finally I decided to call American Radon Systems. The owner, Bill, came to my home within hours of my first call. I was so relieved. He saw the readings I was getting on my radon monitor but did not try to sell me a thing because he wanted to make sure, first, that my older monitor was actually working correctly and recommended I purchase another reliable monitor because he was not wanting us to have to handle a non-existent issue. I appreciated that. We got the new monitor which was not very expensive and tested again. It was syncing up with the other one closely enough that we still decided to go through with the install. Bill is very knowledgeable, friendly, kind, and not pushy -- just straightforward, compassionate and easy-going. We scheduled 2 weeks out and continued to monitor. At one point we wondered if we were overreacting or if we should try other less expensive fixes like improving ventilation, looking for other leaks for radon entry, etc. because I misunderstood what he told me in our initial consultation and thought the procedure would be more invasive than it was, requiring cutting through remodeled spaces, etc., and contacted Bill on the very day the system was to be installed to communicate our reservations. He was so professional! He handled all of my concerns. They came to our home and were so courteous about taking care not to disrupt or dirty our space. They covered the floors, vacuumed all messes made, never left one speck of dirt or any garbage. Jose, the installation tech, was excellent, knowledgeable, diligent, efficient, and practically walked on cat's feet. We were afraid that the install on the outside of the house would be unsightly -- not at all. It blends right in. Anyway...I know this is long but I feel the entire process is important, and not just the final result. The final result: The radon system is basically silent and attractive. Our average radon levels are now measuring 0.8 and as I write this, the level is 0.6. The outside average is 0.4 so we're thrilled! Thank you, Bill and team. You're the best!
