We just moved to the brand new house and use Ductworks for complete furnace and duct clean up of construction debris. Our tech JUL was very professional from the time he arrived up until he left six hours later. Called us before his arrival. He explained what needed to be done and how he is going to do it. He answered all of the questions we had along the way. Jul was very respectful to the household. He did his job without interrupting our day. We will highly recommend the company that maintain to employ people like Jul for many years.
