While many homeowners are beginning to realize the importance of routine duct cleaning, you may still have questions about the process. That's why we've compiled a list of the most frequently asked questions about who should clean your ducts, why it's necessary, and how it's done.
"Why do my air ducts need to be cleaned?"
Over the years, dust, allergens, dirt, and other debris can accumulate in your ducts. In fact, it can build up in layers as much as three inches deep! This filth can trap bacteria and foster mold growth, creating potential health threats for your family. And, to make matters worse, every time your HVAC system turns on, some of these contaminants are circulated throughout your house. Having your air ducts cleaned removes this accumulation of pollutants and greatly improves the air quality of your home. For safe, breathable air, you should have your ducts cleaned at least every four years.
"How exactly is my ductwork cleaned?"
Using specialized tools and a negative airflow system (essentially a huge vacuum), air duct cleaners scrape the dust, dirt, and debris from your ducts. The tools agitate the particles away from the sides of the ducts and the vacuum keeps them from escaping into your house. The cleaning should also include air washing furnace and air conditioner components, vacuuming registers, and applying mold inhibiting agents if necessary.
