How often should you have the duct cleaning in your home done? In most cases, it depends on your specific needs. For example, homes that have something in the area that produces a lot of dust, such as machine plant will need to have their duct cleaning done more often. Those that have allergies should plan to have theirs done more often too.
When considering a professional duct cleaning company, one of the most important things to consider is what they will use to pull the debris from your duct work. You should consider having a company that uses a rather large cart mounted unit to pull the debris out. This will take much more out and be able to work effectively.
