The most authoritative sources, including the U.S. EPA, do not recommend routine air duct cleaning. Instead, they advise cleaning only when there is a specific, verifiable problem, such as visible mold growth, a pest infestation, or excessive dust and debris clogging the ducts.

What the Pros Say
"We don't recommend cleaning for every home. But if you've just renovated, see visible dust puffing from vents, or have confirmed mold, it's a necessary step to restore healthy air. It's a targeted solution for specific problems."
M
Mike Johnson
HVAC Technician, 15 years"Before considering duct cleaning, I tell clients to upgrade their HVAC filter to a MERV 11 or 13 and change it quarterly. That's a more effective, evidence-based first step for capturing airborne allergens."
S
Sarah Chen
Indoor Air Quality Specialist"A proper job isn't just about the ducts; it's a full HVAC system cleaning. We put the system under negative pressure to ensure dust and debris are pulled directly outside, not released into your home. Anything less is just moving dirt around."
C
Carlos Rodriguez
Master Technician & NADCA Member"Our clients with severe asthma often report feeling better after a thorough cleaning, especially when we remove years of construction debris or pet dander. However, we always caution that it's not a cure-all and must be done by certified professionals to be safe and effective."
