Review 1
I had a fantastic experience with the company that installed our radon mitigation system. From the very first phone call, they were professional, responsive, and extremely helpful. They offered a free estimate and took the time to answer all of my questions—especially during the HOA approval process, which made things so much easier for us.

On installation day, the team arrived on time and completed everything efficiently and with great attention to detail. I also appreciated that they provided a free radon test kit, which I’ll be sending to their lab after a week to ensure everything is working properly.

Overall, I highly recommend this company. Their customer service, knowledge, and commitment to quality are truly top-notch.

Review 2
I needed a duct fan replacement in my basement, the guys from Apex came in swapped out my defective fan with a new one in under 30 minutes. The old fan was extremely noisy, I could hear it throughout my house. The new fan is whisper quiet which makes me very happy. I’m extremely impressed with the work that Apex performed for me, I recommend them.
