Q: What is the black stuff around my air vents?

• <div><p>Seeing black dots around the air vents is alarming, but don&rsquo;t worry. It&rsquo;s probably just a build-up of soot and darkened dust. Soot is just a byproduct of burning organic materials, so it tends to form in the winter months. </p></div>

Q: Can I clean my ductwork myself?

• <div><p>You can partially clean the ductwork yourself using a dryer vent brush and a high-powered vacuum cleaner. However, without the proper equipment, you won&rsquo;t be able to reach deep inside the ductwork for a thorough cleaning. A professional air duct cleaning company can remove all the dust and debris from your ductwork and address rust before it becomes a more significant issue. </p></div>

Q: How often should ductwork be cleaned?

• <div><p>Ductwork should be thoroughly cleaned at least every <b>three to five years</b>. An air duct cleaning specialist will need to clean and inspect the ductwork for any leaks or other damage. You can also help keep the air ducts clean by changing out air filters every 30 to 90 days.</p></div>

Q: What happens if you don't clean your air ducts?

• <div><p>If you don&rsquo;t clean your air ducts, dust, allergens, and mold can accumulate, potentially reducing indoor air quality. Clogged ducts can also strain your HVAC system, leading to inefficiency, increasing energy costs, and, worse, the possibility of a complete HVAC breakdown </p></div>
