Most homeowners living in the four-state area of southwest Missouri know the importance of regularly cleaning their air ducts. But it may not be clear what the best practice method is for getting clean air ducts.

So how can a homeowner select a qualified professional to clean the air ducts in their home without knowing what methods work best? That’s what this blog will answer for you today.

Clearing the Air Ducts

Before jumping into how air ducts get cleaned, homeowners should understand that the entire HVAC system needs cleaning, not just the air ducts. By not cleaning the whole HVAC system, there is a high risk of re-contamination, which minimizes the benefits of cleaning your air ducts. 

The standards according to NADCA, the National Air Duct Cleaners Association, there are critical components in an HVAC that need cleaning or replaced, which include:

  • Air cleaner
  • Air ducts
  • Coils
  • Grills
  • Registers
  • Air plenum, or distribution box
  • Blower and assembly
  • Heat exchange
  • Air filters

Dislodge Contaminants in Air Ducts

The first step to efficiently cleaning any HVAC is establishing negative air pressure in the duct system, which better protects the ductwork from damage. According to the NADCA standards, negative pressure is critical “to prevent contaminants from spreading throughout the home.”

Once the negative pressure is stable, some form of agitation device gets pushed and pulled through the supply vents to the trunkline connected to the furnace. Some standard agitating equipment includes:

  • Compressed air whips with nozzles
  • Cleaning hoses
  • HVAC Brushes (often depends upon the ducting in a home)

Once all the contaminants are loose, everything gets vacuumed up. Most professional cleaning companies have truck-mounted vacuums that can pass through a home’s entire air duct system. In contrast, some professionals use portable vacuums, like “rotovacs,” that cannot pass through a whole air duct system and often underperform at vacuuming contaminants.

Antimicrobial Application

The final step in air duct cleaning is as important to you and your family’s health as having the air ducts in your home cleaned annually. These chemicals are registered with the United States Environmental Protection Agency, or the EPA, as safe for use in homes and businesses.

After cleaning, your team of professionals at Angel Clean will use a sanitizing fog inside your home’s air ducts, a plant-based sanitizing solution that is safe for all. They also use the same sanitizing solution to clean parts of the air handler to help it function better by improving airflow.
