I would highly recommend Ductworks to clean the vents in your home. I had some extenuating circumstances where I had construction debris in my vents, making them quite dirty, but I also had recently refinished my wood floors throughout my home. It was imperative to have the floors heavily protected and I could not have asked for a better technician to handle the job than Luis. The person with whom I made the appointment had conveyed my concerns about protecting the floor and Luis came fully aware of the situation and prepared to take extra precautions. He didn't blow off my concerns or act like they were ridiculous, which I appreciate. So, not only did he thoroughly clean all of my vents and furnace (the before and after pics matched the ones I took myself ;-), he did so in a kind, professional and careful manner. I'm not sure if you can request a specific technician, but if you can, I would highly recommend Luis all day, every day!
