I want to compliment the technician who cleaned our dryer vent/duct today. I do not recall his name but the initials on the invoice appear to be W. E. This is the first time we have had the system cleaned since we built the house in 2004 and, consequently, we had no idea of the problems that would crop up due to the location and length of the duct, numerous 90 degree angles and the fact that a blower had been installed. This man worked diligently for approximately four hours on a job which, as I understand it, was expected to take an hour and a half. Despite the frustrating nature of the job, he remained polite and professional and willingly took time to explain the issues. Based on my observations today, I would not hesitate to recommend your company to others.
