Luis, Robert and Lonny (came a little later) are the workers that came to my house to clean the ducts. They were all polite, friendly and professional. I don't think our ducts have ever been cleaned in our house before so needless to say they were pretty bad. I can't believe the before and after pictures. I wish I would have done this a long time ago. I can't imagine all the dust and particles my hubby and I have been breathing. Anyway, it is done and they are clean. They were all hardworkers and I called 4 of my friends to refer Ductworks to them and the guys that did such a great job on my house. Thank you Ductworks for providing such great service and workers!!!
