"I have zero complaints about our tech, Jack. He was thorough and communicative! We have a system installed through the roof and he was able to paint the exhaust pipe to match the shingles. The front office wasn't as great. We had to schedule a follow up visit because the initial install wasn't going to work. Unfortunately they never put me on the schedule the second time. So my install day came and went but we didn't hear anything from Swat. I calle the next day and no one knew what I was talking about. Our account manager (Brian) was very apologetic and offered to take some money off our install because of the confusion and the fact that there were no available appointments until August 11th. Luckily they were able to add me to the top of their cancellation list, so we ended up with a system just 3 days later. I appreciate their willingness to make it right with me. I would reccommend them to others looking to have a radon abatement system installed."

"Chris promptly responded to my inquiry. We set the inspection for a week later. The night before he confirmed that he would be at the appointment. When he arrived he was pleasant and professional. He identified issues of concern and otherwise offered advice about improvements to systems."

Radon Detection and Reduction FAQs, answered by experts

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.

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

Many radon fans carry a five-year manufacturer's warranty. That said, your radon fan should last between five and ten years. Regular inspections will ensure the fan is operating properly. Unusual or exceptional noise coming from the fan or indications on your manometer or system monitor can immediately tell you that something is amiss.
