Filtration Lines

Do you have a darkening of the carpet along the edges of your wall. This is caused by your homes HVAC system. You will notice that the problem is worse the closer you go to the return air system. When your HVAC system is running , air is being drawn to that return air grid (essentially a vacuum). Air is then pulled under walls and doors and turns your carpet into a filter. The stain left behind is carbon based and requires special treatment to remove. I have the products and techniques to remove these unwanted stains. I can also go as far as to repair the problem permanently. Please call for a free estimate. 865-951-9816
