I have contacted 3 companies; SK Cleaning Service was the only one who came in on time! He knows his stuff, recommended on a better and well-organized system then I asked for. And the price was so nice! I appreciate an expert contractor who cares about his clients, not just his money. The workers came as planned and on time, used floor and dust protection wherever required. They know where the most excellent place to position is the ducts’ outlets, thermostat in the best place to use. I installed a full HAVC system, replacing old gas wall heaters. What a change; I really upgraded the superiority of my life, and thanks to SK Duct Cleaning, did it with no too much hassle. The price was Fair, great service and great communications. Defiantly will recommend him to friends, I actually did already.
