We recently had a fan installed, and I couldn't be more pleased with the experience. From the initial consultation through the final installation, the team was professional, knowledgeable, and courteous. The quality of the installation was excellent. The system is working exactly as promised. Highly recommend!

I had a noisy blower that was about 10 years old. A-1 gave me an honest opinion on replacement vs a service call to evaluate vs living with it until it became unbearable. After reaching unbearable status, A-1 promptly sent a tech over to change out the blower in a 15 minute visit.

Scheduling with Adam was very easy and he sent a technician to my home within a week. I always get three estimates for any home improvements or repairs. This company was half the price compared to two other radon companies. You can't go wrong going with A-1 Radon!

I needed a radon mitigation system installed. Everything about the process was perfect. From the first test, to the installation, to the final follow-up test, Adam did a great job. The price was fair for the work completed. The quality of the work was very good. Definitely recommend.

Had A-1 Radon of Sheboygan in May 10, 2023. One day levels were reading 4.35pCI/L, long term level near 6pCI/L. Installation by a knowledgeable and courteous employee, who with consultation, came up with a great idea for minimizing visual placement of fan. Today, one day levels are at .35pCI/L, over 92% reduction. Fantastic! Great work A-1! John Weber
