Michael and his teammate were extremely friendly and impressively professional. They pulled in on time. Both properly uniformed, both polite and easy going. It took them 3.5 hours to be done with my 3500 square foot house, which was the quote I received over the phone at the time of booking. Now after the job I can see the difference: the air has a different smell and taste and it feels like I have just renovated the entire house – it’s that good. I'm extremely satisfied with the service provided by Sem's duct cleaning and I am especially charmed by the skills and professional approach Michael displayed while onsite.
