"We were 100% pleased with the work done by A1 Radon Services. They were able to schedule us quickly, they arrived right on time, and the installation went perfectly. A short time later we tested again for radon and the number had gone from 9 to 1. We highly recommend. them."

"Sam was on time for the estimate appointment that was scheduled. He was very friendly and professional. He was not pushy in any form. On the day of the scheduled service appointment he showed up ready to work and was again very friendly and easy to communicate with. He got the work done in a very reasonable amount of time and his electrician showed up on time and was the same. We will have our after mitigation radon testing done and I will update my review then."

"Very precise in first measuring the level of Radon present, and although well within suggested limits, per my insistence, turned our Passive system into an Active system by installing a fan in the attic to ensure any Radon would be exhausted into the air despite our overly long piping. Working was done quickly and monitoring was explained by Dan and he also provided a pre-paid test kit to check the level of Radon after the fan and monitor were installed."

Radon Detection and Reduction questions, answered by experts

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.

No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.
