As Roque worked on the maintenance, I reviewed the Air Scrubber literature. He mentioned it to me when I complained about my allergies. No sales pitch or pressure, just information about a product he believed would help me feel better. It’s too soon to tell for sure but I believe it’s helping with my allergies and overall air quality issues. My prior HVAC company sent a different tech every time. None of whom are as knowledgeable and trustworthy as Roque. Very happy and I will recommend your company whenever I can. Very, very happy!
