What is Negative Air Pressure in Air Duct Cleaning?

Negative air pressure is a powerful air duct cleaning method that is highly effective at removing contaminants from your home’s air ducts. By using a powerful vacuum to create suction, negative air pressure extracts air from the duct system and draws in dust, debris, and other contaminants. This method is often considered the best air duct cleaning option, as it turns your furnace and ductwork into one large vacuum.

Stay Away From These Duct Cleaning Methods

However, it’s important to note that not all air duct cleaning companies use negative air pressure. Other methods may include brushing or blowing compressed air through the ducts. Please understand that these methods are cheaper and they are not as effective at removing debris from HVAC system. The vacuums do not create enough CFM to draw in all the agitated debris.

Another method is the contact cleaning method, where the cleaner physically scrubs the ducts using brushes or other agitation tools. While this method is effective at removing surface-level debris, it may not reach deep into the duct system to remove all contaminants.

Conclusion

When choosing an air duct cleaning company in Milwaukee, it’s important to ask about their methods and equipment. A reputable company will use negative air pressure or another highly effective method that can remove all contaminants from your ducts. Don’t forget to ask about the CFM and PSI ratings on their equipment because not all equipment is created equal.

While negative air pressure is often considered the best air duct cleaning method, it’s important to understand the other options available. Choose a company that uses the most effective method for your specific needs to ensure the best results for your home and indoor air quality.
