It can happen in the cleanest homes you know, including yours. “It,” in this case, is dirt forming on or near your air supply vents and registers.
When people first notice, it’s easy to assume that the dirt particles stem from inside the ductwork. Let’s call that a “yes and no”.
You see, when conditioned air flows through your wall or ceiling registers, it’s flowing at high velocity. That causes air turbulence and causes the conditioned air to interact with dust, dirt, pet dander, and other contaminants already in the air. This interaction causes the dirt to adhere to the registers and wall space around them.
Now that you know the source of the problem, here’s how to prevent it:
Clean or replace your heating and air filters regularly to help keep dust and dirt out of your living spaces.
Once a week, thoroughly vacuum and dust your home.
Keep doors adjacent to your garage closed and well-sealed.
Don’t smoke indoors, and don’t allow anyone else to do so, either.
Have a professional determine if your kitchen range is properly vented. Many such fans simply return the air back into the home.
Don’t burn cheap, inefficient candles indoors.
More than anything, signs of indoor air pollutants indicate a clear need for heating or cooling system preventive maintenance. In fact, with a thorough system cleaning and inspection performed by one of our experienced technicians, you can look forward to more than cleaner air.
