It's been a while since your team completed the air seal on our ventilation system. We have noticed a definite difference in our air quality and are *very* happy we had you guys come! It was worth the money we paid, and you can freely use my name for any solitications of future work, as a happy customer. I was skeptical that it would work, but it looks like it did work well enough to make a significant improvement in our air quality!
