Dust Blowing from Registers
Visible dust or debris blowing from supply registers when the HVAC first kicks on is the most direct sign of accumulated duct contamination. This debris recirculates through your home on every cycle.

Signs to Look For
6 Signs Your Ducts May Need Professional Cleaning
Most homeowners don’t know their ducts need cleaning until a technician shows them what’s inside. These are the most common indicators AIRONE finds in the field.
Musty or Stale Odor When System Runs
A musty, dusty, or stale smell that appears only when the HVAC is running typically indicates biological growth - mold, mildew, or microbial buildup - somewhere in the duct system or air handler.
Recent Home Renovation
Construction dust - drywall particles, insulation fibers, wood dust - infiltrates duct systems during renovation. AIRONE recommends duct cleaning after any remodel that involved cutting, sanding, or demolition work near HVAC registers.
Rodent or Pest Intrusion
Evidence of rodent or pest activity in the attic or crawl space - droppings, nesting material, or damage to duct insulation - means contamination has entered the duct system. This is one of the most urgent reasons for professional cleaning.
Visible Mold Inside Registers
Visible mold growth on register covers or visible inside the duct opening when a register is removed indicates active biological contamination inside the duct system that a standard filter change will not address.
Moving Into a Previously Owned Home
Unknown duct history is one of the most common reasons AIRONE recommends cleaning. Previous owners may have had pets, smokers, renovations, or deferred maintenance - all of which leave residue in the duct system.
The NADCA Standard
What Does NADCA-Standard Duct Cleaning Actually Mean?
NADCA is the National Air Duct Cleaners Association. The NADCA standard defines how professional duct cleaning must be performed - and it is more rigorous than what most discount duct cleaning services actually do.
What does NADCA-standard duct cleaning require?
The NADCA standard requires two things used together: mechanical agitation to physically dislodge debris and biological buildup from duct walls and components, combined with HEPA-filtered vacuum extraction to capture the dislodged material and remove it from the system before it can settle back into your living space. A blower flush alone or compressed air cleaning alone does not meet the NADCA standard.
What does AIRONE actually inspect and clean during a duct cleaning service?
AIRONE technicians inspect and clean supply ducts, return air ducts, supply and return registers and grilles, the air handler including the evaporator coil area and blower compartment, the drain pan, and all accessible duct connections. Before and after inspection confirms cleaning effectiveness at each section of the system - not just the visible register openings.
Why does it matter that AIRONE is a licensed HVAC contractor and not just a duct cleaning company?
Duct cleaning performed by technicians without HVAC licensure can damage flex duct connections, disturb evaporator coils, introduce moisture into the system, or miss contamination in the air handler that a non-licensed crew is not qualified to assess. As a CA License #114807 C-20 licensed contractor, AIRONE technicians understand the full HVAC system - not just the duct runs.
Our Process
What Does AIRONE’s Duct Cleaning Process Look Like Step by Step?
Every AIRONE duct cleaning job follows the same 5-step process from initial inspection through post-cleaning confirmation.
Step 1 - Schedule and Pre-Visit Checklist
Call (323) 471-1037 or use the form on this page to schedule your duct cleaning appointment. AIRONE schedules Monday through Saturday 7 AM to 7 PM. Before the visit, confirm that all HVAC registers are accessible and that the area around the air handler unit is clear. None of this is required - the technician handles everything on-site - but it reduces service time.
Step 2 - Full System Inspection Before Cleaning Begins
The technician inspects the full duct system before any cleaning equipment is deployed. This includes visual inspection of all accessible supply and return registers, the air handler compartment, the evaporator coil area, the drain pan, and any visible duct connections in the attic or crawl space. The inspection determines the extent of contamination and identifies any sections that require special attention - including sections with suspected mold, rodent damage, or significant debris accumulation.
Step 3 - Mechanical Agitation of Duct Surfaces
AIRONE uses mechanical agitation tools - rotary brushes and air whips appropriate for your duct type - to dislodge accumulated debris, dust, biological material, and any compacted buildup from the walls of supply and return ducts. The agitation method is matched to the duct material: sheet metal ducts, flex duct, and fiberboard duct each require different contact pressure and tool selection to clean effectively without causing damage.
Step 4 - HEPA Vacuum Extraction
Simultaneously with or immediately following mechanical agitation, AIRONE connects HEPA-filtered vacuum extraction to the duct system. The HEPA vacuum captures dislodged particulate matter - including fine dust, mold spores, insulation fibers, and biological debris - before it can settle back into the duct system or enter your living space. HEPA filtration captures particles 0.3 microns and larger, which includes the fine wildfire smoke particles and biological contaminants most relevant to Southern California households.
Step 5 - Post-Cleaning Inspection and Duct Condition Report
After cleaning is complete, the technician performs a post-cleaning inspection of all cleaned sections and provides a verbal and written summary of what was found, what was removed, and any duct condition issues observed - including leaks, disconnected sections, damaged flex duct, or coil condition concerns. If duct sealing or repair is warranted, AIRONE provides a separate written estimate. There is no obligation to proceed with additional services.

When Should You Combine Duct Cleaning with Other IAQ Services?
Duct cleaning removes what is already inside your duct system. These companion services address the conditions that allow new contamination to accumulate.
Duct Cleaning and Duct Sealing - Why Do Both?
Duct cleaning removes accumulated debris from inside the duct system. Duct sealing closes the gaps and leaks that allow new debris - attic dust, insulation fibers, unconditioned air, and outdoor pollutants - to re-enter the system. According to the US Department of Energy, duct leakage wastes 20 to 30 percent of conditioned air in a typical home. Doing both in the same visit reduces total labor cost and means the sealed system starts clean.

A freshly cleaned duct system is the right time to upgrade your air filtration. Installing a MERV 13 or whole-home air purifier after duct cleaning means the upgraded filtration starts with a clean baseline - not a contaminated system. AIRONE can assess whether your HVAC system airflow supports a MERV 13 upgrade at the same visit.
View Air Purifier and Filtration Options →Post-Wildfire Duct Cleaning - What AIRONE Recommends
After a significant wildfire event where the HVAC system was running during heavy smoke conditions, AIRONE recommends professional duct cleaning followed by a MERV 13 filter replacement and - for households with respiratory sensitivities - consideration of a whole-home air purifier or UV-C sanitizer installation. This combination addresses particulate accumulation in the ducts, improves ongoing filtration, and reduces the biological load from smoke-related microbial activity.

FAQ
Duct Cleaning Los Angeles - Frequently Asked Questions
AIRONE provides itemized duct cleaning quotes after a system inspection. Pricing depends on home size, number of supply and return registers, duct system layout, and condition found during inspection. Contact AIRONE at (323) 471-1037 for a written estimate.
NADCA - the National Air Duct Cleaners Association - recommends professional duct cleaning every 3 to 5 years for most homes. You should schedule cleaning sooner if you have recently completed a renovation, experienced rodent or pest intrusion, noticed visible mold growth inside registers or ducts, or are moving into a previously occupied home with unknown duct history.
The NADCA standard requires mechanical agitation to loosen debris from duct walls combined with HEPA vacuum extraction to capture and remove dislodged particles without releasing them into your living space. This is more thorough than a simple blower flush or compressed air cleaning. AIRONE follows the NADCA standard on every duct cleaning job.
Signs your ducts may need cleaning include visible dust or debris blowing from registers when the HVAC runs, a musty or stale odor when the system is on, increased allergy or respiratory symptoms at home, visible mold or debris inside register covers, a recent renovation, pest intrusion, or purchase of a previously owned home. An AIRONE technician can inspect your duct system and confirm whether cleaning is warranted.
Yes. After a wildfire event, fine smoke particles can settle inside duct systems - especially when the HVAC was running during heavy smoke conditions. Professional duct cleaning removes this accumulated particulate matter and restores clean duct surfaces. Pairing duct cleaning with a MERV 13 filter upgrade or whole-home air purifier provides the most complete post-wildfire indoor air quality recovery.
Professional NADCA-standard duct cleaning performed by a licensed HVAC contractor does not damage properly installed duct systems. Risks arise from unqualified technicians using improper equipment or excessive pressure. AIRONE technicians are licensed and experienced with all duct system types common in Southern California - including older flex duct, sheet metal, and fiberboard duct systems.
Yes. Duct cleaning removes accumulated debris and contaminants. Duct sealing closes the leaks that allow new contaminants to enter the system and also stops conditioned air from escaping - which the US Department of Energy estimates wastes 20 to 30 percent of conditioned air in a typical home. AIRONE recommends duct inspection after cleaning to identify whether sealing is warranted.
