Steve, thanks for taking the time to write about your experience with us. It's just a common courtesy to keep you informed on our arrival, so your not sitting around wondering if were even going to show up, so glad you appreciated the call. We always do a system assessment to make sure you infact need duct cleaning to be done. With a newer home, having it done not to long ago, the condition wasn't at all a worry. Doing some small cleaning out of the vents, having the system disinfected, filters changed, was pretty much all that was needed. Most companies just show up, blow air down the vents, but really, that does nothing. When the time comes for the job to be done, you want it done properly. Whether you use us, or another company, just make sure they are certified (NADCA - National Air Duct Cleaners Association) Thanks for the kind words and we look forward to serving you in a few years. Keep me posted how that HEPA installation goes for you. Hope you and your family have a wonderful new years eve. All the best. Paul
