Kianoosh and Jeramiah were so friendly, genuine, polite, and conscientious as they worked carefully to communicate what services they could provide to clean all the air ducts (intakes and outtakes), showing me what each duct looked like before and after they cleaned and sanitized everything. They worked systematically and thoroughly, making sure that they were careful to not miss any detail. I enjoyed the opportunity to chat with them as they worked. Highly recommend!
