This duct cleaning experience was even better than we had anticipated. Chris did a fantastic job from his set-up through finish. It happened to be a very cold day, 2 degrees above zero. He made every attempt to keep the heat in the house, keeping the doors and windows sealed off as much as he could. He walked us through the process before the job, and after. It all lasted about 3 1/2 hours. When he was done, we could already notice the difference, as the sun was brightly shining through our windows in our home, and we could see very few dust particles milling about in the rays. In the days following, our sleep is like a breath of fresh air..a noticable difference from allergy symptoms. We also notice a much cleaner home as dusting seems to be not needed. Great job…very worth the cost…will highly recommend to even my most picky friends. Might I also share the fact that the scheduling and explanation of service was well handled by Verna on the phone. My experience was comfortable and not high pressred at all, as most people expect when the call a contractor. She was even thoughtful enough to re-schedule us earlier, as we preferred, when a cancellation left an opening. Thanks again to Safety King.
