Absolutely impressed with their sales. Cliff phoned me to give me an estimate and answered my questions professionally. Their starting costs are better than almost everyone else who does the furnace and duct cleaning (even the per extra vent cost). The gentleman who came to our home was on time, and got to work right away. He said it would take about an hour and he was right on the money (about and hour and 10 mins). He then notified me about their spray that helps keep dust mites down and can help people with asthma (he mentioned it because it was on sale %50 off). It only took maybe 10 minutes and it smelt pretty good. Absolutely impressed with the service, their response time, their porfessionalism, and their prices. Would 100% recommend to anyone, especially if they are having deals/sales.
