Dusting, sealing the window sills and cracks, installing a great air purifier are some of the many ways of keeping dust out of your house. But even after doing everything, sometimes you may still find dust floating in your air and living spaces. So, how do you keep dust from coming out of vents?
You can stop dust from coming out of vents through regular inspection and cleaning of your duct-work, fixing of any cracks or faulty in the system and replacement of dirty or worn out air vent filters.
Why is dust coming out of vents?
There are two main reasons for dust coming out of your heating and cooling vents; faulty ductwork and clogged vent filters. During renovations or building the house, construction works produce lots of concrete dust that is sometimes left in the crawl spaces.
When this happens and the duct has some cracks that are leaking, the dust in the crawl spaces will find its way into the living spaces through the vents.
Faulty, worn out or clogged air vents filters could also be a major reason for dust coming out of your vents. Instead of trapping dust floating in the air, the worn out filters redirect it to the house. Air filters need a regular cleaning or replacement as recommended by their manufacturer.
What is the black dust around vents?
Having black stuff around your vents is an indication of serious issues within your ducts and the HVAC filters. When coupled with other signs such as frequent sneezing, coughs, difficulty in breathing, runny nose, and skin irritation among others, it is clear that you are living with black mold in your house. But where could the mold be coming from?
Mold thrives well under moist, warm, and low light conditions, all of which are available in the ductwork. Moisture is a result of the humid conditions that are eliminated by the purifier, while warmth comes from your cooking, especially if you do not have a range hood installed in your kitchen.
And because there is debris created by dust accumulation, this forms a perfect medium for the growth of mold in the dark air duct. Heavy-duty cooking also produces lots of smoke that contains black particles known as soot.
Together with cool breeze from outside, the mold and soot are blown back into your house by the conditioner through the cooling vents. The black stuff does not have to be mold or soot; it could also be dark dust sucked in through leaks in the air duct.
Fortunately, there are a number of ways to get rid of black dust around air vents. However, you may need to hire professional HVAC cleaners to handle the problem.
