Hi Chris, I just wanted you to know how pleased I was with the duct cleaning that took place this morning. Both Frank and Michael were professional, courteous, neat, and very nice. I apologize, but I don't remember the individual's name who started up the job, he too was very courteous and nice.He explained the entire job, prior to work commencing. Your company is fortunate to have such great employees. I would ask that you please pass this along to their supervisor.
