There is some disagreement within the industry about the best method for cleaning air ducts.  The two schools of thought are the “negative air” approach and the rotary brush and vacuum approach.  We believe that both air duct cleaning methods can achieve great results in most situations when performed properly by competent technicians.  However, our focus has always been on high quality residential service.  The type of residential duct work commonly used in homes in the South poses unique challenges to duct cleaners because it is soft, flexible, and does not go in straight lines.  Firms using the negative air approach are especially challenged by this type of duct work, as that process was originally designed to work well on the rigid metal duct work commonly found in the North and in large commercial buildings.  The tools used to agitate the duct work in negative air cleaning are very difficult to get all the way into your duct work and can damage the lining of the ducts we find in most residences in the greater Jacksonville area.
Air McCall’s comprehensive Duct Cleaning process includes the use of a fogging machine to sanitize your duct system with an all-natural biocide that is harmless to you and your family, and your pets as well. Most companies use a sprayer (not a fogging machine) to try to sanitize the duct system but the sprayers are not effective to treat the entire duct system.
"So My A.C. suddenly went belly up and I needed a total brand new unit inside and out. So a little background on myself. I'm an engineer, so I know a little bit about A.C. and how they work. I'm by no means an expert, but it does allow me to detect if the A.C. guy knows his stuff, especially if they don't know what I do. 😉 And I'm happy to say, these guys do. One of the things that helped me chose them is that they brought up the importance of controlling humidity. None of the other contractors I spoke to, mentioned that. I also appreciate the fact that he didn't try to "up sell" me and get me to buy things I didn't need. He was on time, honest and forth coming about what I needed and what I didn't. When the workers came, they were on time, very professional and very CLEAN. After they left, I couldn't tell they had been there. Highly recommended this service."
