The Duct Cleaning Gurus
Your HVAC system is blowing
mold spores into every room.
When mold grows in your crawl space or walls, the spores get into your ductwork. Every time your heating or AC kicks on, those spores circulate through your entire house. Cleaning the ducts is how you stop breathing them in.
Why duct cleaning matters after mold remediation
You can remediate every visible bit of mold in your crawl space, but if your HVAC system is full of spores from before the remediation, you're still breathing them. Proper mold duct cleaning is the step that actually clears your air. We clean inside the ducts and supply boots because lingering mold and spores can still make you sick. Most air filters are not capable of catching spores because they're too tiny; they pass right through. And when mold is actively growing inside the ductwork itself, we treat it on the spot, full mold remediation in air ducts, not just cleaning.
HVAC Duct Cleaning: Ducts, Boots & Insulation
Supply & Return Ducts
The full duct system, from the air handler to every vent in your home. We don't just clean the parts you can see.
Supply Boots & Registers
The boots where ducts connect to your floor or ceiling vents are common collection points for dust, debris, and mold. We clean and inspect every one.
Duct Insulation Inspection
We check whether your ductwork is properly insulated. Uninsulated ducts in a crawl space are a condensation factory. If insulation is damaged or missing, we'll let you know.
NADCA trained
Our team is trained through the National Air Duct Cleaners Association (NADCA), the standard for professional HVAC cleaning. That means proper equipment, proper procedures, and results you can actually trust.
Frequently Asked Questions
How often should HVAC ducts be cleaned?
Every 3 to 5 years for most homes, but immediately after mold remediation. If you've had mold removed from your crawl space or walls, the spores are almost certainly in your ductwork. Every time your heating or AC runs, those spores circulate through your entire house. Cleaning the ducts after remediation is how you stop that from continuing.
Can duct cleaning actually make things worse?
Yes, if done improperly. Bad duct cleaning dislodges mold spores and dust without properly capturing them, which sends contaminants into every room of your house. That's why NADCA training matters. Our team follows proper containment and extraction procedures so that what comes out of the ducts doesn't end up in your living space.
What is NADCA and why does it matter?
NADCA is the National Air Duct Cleaners Association, the industry standard for professional HVAC cleaning. NADCA-trained technicians use proper equipment, follow tested procedures, and understand how to clean duct systems without spreading contaminants. It's the difference between actually improving your air quality and just shuffling dust and mold around.
How do I know if my ducts need cleaning?
Signs include visible dust or debris blowing from vents, a musty smell when the HVAC runs, increased allergy symptoms indoors, or recent mold remediation work. You can also look inside a vent register: if you see dust buildup or discoloration, the rest of the system likely needs attention.
What does professional duct cleaning actually involve?
We start by assessing your duct system — air handler, supply and return ducts, boots, registers — and identify any visible mold or heavy contamination. Then we set up containment so spores don't spread, run rotating brushes through every duct to physically dislodge dust and mold spores, and capture everything with HEPA-filtered extraction. We clean the supply boots (where ducts meet your floor or ceiling), inspect duct insulation, and finish with a final pass to confirm the system is clean. NADCA-trained from start to finish.
How does mold get into my HVAC system?
Mold colonizes anywhere with moisture and a food source, and HVAC systems offer both. Spores from a contaminated crawl space circulate through your home and get pulled into the air return, settle inside the ductwork, and recirculate through every room every time the system runs. The system becomes a re-delivery mechanism for the contamination it picked up somewhere else. That's why cleaning the ducts is essential after any mold remediation job.
Can mold in my ducts make me sick?
Yes — and the duct system makes it worse than mold sitting in one location. Mold spores in ductwork get distributed throughout the entire house every time the HVAC runs, and your air filters can't catch them, because the spores are too small. So they pass right through the air filter. People with allergies, asthma, immune conditions, or kids in the house often see symptoms intensify when the heat or AC kicks on. Persistent musty smells, headaches, or respiratory issues that improve when you leave the home for a period of time are common signs.
What equipment do you use to clean ducts?
Rotating-brush systems for the physical cleaning — these run through each duct line and physically dislodge dust, debris, and mold spores from the inner walls. HEPA-filtered negative-air machines for extraction, so what comes out of the ductwork doesn't end up in your living space. Personal Protective Equipment (PPE) is utilized when we're working in contaminated systems. NADCA-standard equipment, used by NADCA-trained technicians.
Just a few vents?
Small house, 8 or 10 vents, hasn't been cleaned in a while? We do quick duct cleaning jobs regularly. Doesn't take long, doesn't cost an arm and a leg, and makes a real difference in your air quality, especially if you've got allergies.
Large system or post-remediation?
20+ vents, multiple HVAC zones, or you just had mold remediation and need the spores cleaned out of your entire duct system. We handle large residential and commercial duct cleaning with NADCA-trained procedures. Every duct, every boot, every register.
Either way, the inspection is free. Call 855-705-6653 and we'll tell you exactly what you're looking at.
