Whole service took about 2 hours for air duct cleaning and carpet cleaning for (4 rooms, hallway and staircase).
All Corners of the rooms/hallway/staircase of the Carpet were still dirty. It didn't look it was done or wash properly. We were told not go upstairs because it will take 3 hours to dry but it took much longer than that. After 5 hours we couldn’t even walk on it. It was extremely wet.
Air Duct cleaning was very quick. It was done less than half hour. The setup took longer than any of the cleaning.
We had a free promotion to get the dry vent or central vacuum done, we choose dry vent but this couldn't get completed because our vent from outside was blocked. So the technician did the central vacuum instead. Honestly i wasn't watching him, he did it through the garage and left without telling us he was complete.
I guess never pay in full especially in CASH until ALL full service were completed and checked. Best is to inspect and stick around any contractors to make sure all area are covered.
