Initially, I was dubious if cleaning my vents was necessary. Our home was built 8 years ago and I didn't think it was very dirty. Wow, I was surprised to see so much sawdust, dog hair, moths and more! Jul, the technician, was very professional, listened to my initial concerns and took pictures of each vent before and and after. My vents look like they are new! I didn't realize that my furnace would get such a cleaning as well. Kyle, the second tec, explained to me their process of cleaning the vents and furnace. I feel that both technicians really took care of my home and treated it with great respect. I will recommend Ductworks to everyone!
