I was reluctant to go with Prop-Air because of a couple bad reviews I read. But as it turns out, they were awesome. Not only was the price wayyyyy less than the other competitors I called, but the staff was polite and professional. The person I called to book the appointment was as nice as can be and the technician who came, Ludovic Henry did an excellent job! He was on time and very friendly. I was surprised how much crap came out on my ducts! I will use them again for sure at my other property.
