Marcus and Eric arrived on time as scheduled and took just over 2 hours to complete the job. After I showed them around the house they explained what they were going to be doing and asked if I had any questions. I had a few questions which they answered satisfactorily. They then put on protective shoe coverings and went about their work professionally. Later, they offered a list of options, no high pressure, one of which they recommended; deodorizing, which I agreed to. When they were finished everything that was moved was put back into place; such as basement ceiling tiles, etc. They even installed a new furnace filter that I had purchased. This is my first experience with duct cleaning and I would recommend this company to anyone. Good job guys!!
