This is a common problem when a system is getting older, or has had ground moisture problems over the years. Eventually the metal will rust and break down, allowing entry points for dirt to enter. This is especially true on the floor vent boxes. Duct Coating will remedy all of these problems and halt the dirt from blowing out every time you turn the system on. Duct sealing will also make the system work more efficiently.
Again, this is a very common complaint with in-slab air ducts. Typically we find that additional drainage is required, or simply changing the way you irrigate to help the soil around the home dry out. Water will always find the path of least resistance and when water migrates under your home, it thinks the air ducts are a drainage system. Actually water in your air ducts is alerting you to a much bigger problem; water eroding your foundation. When we come out to inspect your ductwork, we will inspect the exterior of the home and give you recommendations on drainage and irrigation in our comprehensive report. Once these recommendations are completed and the ductwork can remain dry, repairs and duct sealing with Duct Armor will ensure your ductwork is safe and clean for many years to come.
This is typically due to overly saturated soil under the foundation. If the ductwork has water issues or a high moisture content, bacteria and mold may form quickly. We see this quite often and we have the ability to help guide you on water management and repair of the ductwork.
Sometimes we find that animals may have gotten into the ductwork and left their debris, or died inside the duct runs. Our camera inspection can identify the problem and help us to find the solution to remediate the smell. Many times duct cleaning may not be enough to remove residue left by animals (rats, mice, skunks, opossums, etc.). Our duct coating process will eliminate the smell completely by fully encapsulating the interior of the ductwork.
This is a common question. We have never seen ductwork collapse without there being significant structural damage to the floors and foundation of a home. This is a rare occurrence. However, what we do find is that so much dirt has piled up in the system that it will "clog" the flow of air. This is usually due to rusted metal, water intrusion bringing ground soil in with it, and overall breakdown of the metal. A thorough and professional cleaning and coating with Duct Armor usually fixes the problem of diminished air flow.
This is always an option and during our inspection, we will always give you a honest answer if we feel this is the right direction to go. However, many times clients find that once they actually get to see what is inside the ductwork, they find it is not as bad as they thought. Also, the cost to remodel and go overhead can typically be 3-4 times the cost of Duct Armor and will take weeks, if not months to complete. The Duct Armor coating is done in 1-2 days depending on the condition of the system. Down time is an important factor as no one wants to live in a construction zone unless you have to.
