Booked Double Diamond after reviewing a bunch of options based on reviews, awards, and name recognition. Had all my 10 ducts, & 2 return vents cleaned by Mike & Kyle. They showed me the process in detail and were extremely thorough and professional, as well as genuine great people all around. Arrived on time. They wore masks (as per Covid) and took all safety precautions. I ended up adding in a furnace cleaning because they were already here and I’m sure it needed to be done. My mind is now at ease, we haven’t had this cleaning performed and bought the home 3 yrs ago, (who knows when it was last done?) I would absolutely recommended them, they had both been doing this for over 10 years and have mastered this skill. Also I was shown before and after with a mirror, HUGE difference.
