Your air ducts are the hidden highways of your HVAC system—delivering clean, conditioned air to every room in your home. But over time, those ducts can become clogged with dust, debris, mold spores, allergens, and even pests—compromising your indoor air quality, HVAC performance, and energy efficiency.
At AtticShield, we provide professional air duct cleaning and repair services designed to restore clean airflow, reduce health risks, and improve energy savings. Whether you’re concerned about air quality or suspect leaks or damage in your ductwork, our expert team is here to help you breathe easier.
Ducts collect pollutants like pet dander, pollen, mold spores, and dust mites—and then circulate them throughout your home. Regular cleaning helps eliminate these contaminants and supports a healthier, allergen-free environment.
Clogged or leaky ducts force your HVAC system to work harder. Clean and sealed ducts improve airflow and reduce strain on your system—leading to lower energy bills and fewer breakdowns.
Moisture inside ducts promotes mold growth and foul odors. Our cleaning process removes moisture-trapping debris and prevents mildew and bacteria buildup.
Routine cleaning and prompt repairs reduce wear and tear on your system’s components—helping you avoid expensive repairs or early equipment replacement.
We perform a detailed visual inspection of your duct system to identify visible leaks, disconnected sections, blockages, and areas of contamination. We assess the condition of your ducts and determine the best approach for cleaning and repair.
We remove dust, debris, insulation fragments, and rodent contamination from accessible ductwork using brushes, vacuums, and hand tools. This process clears buildup and biological contaminants from the entire duct system that can restrict airflow and affect indoor air quality—safely and thoroughly.
We apply EPA-registered disinfectants to kill bacteria, viruses, and fungi to help neutralize lingering odors from rodent activity or dust buildup—creating a cleaner, healthier environment for your home.
Cracked or leaky duct sections are repaired using professional-grade mastic sealants, reinforced insulation, or replacement materials to restore integrity and optimize airflow.
After completing the cleaning and repairs, we turn the HVAC system back on to verify proper operation and airflow throughout the ductwork. Our technicians confirm that all connections are secure and air is moving as expected.
Our technicians are experienced in industry-recommended cleaning methods, follow California code requirements, and are skilled in identifying and resolving common duct system issues.
We use durable, contractor-grade vacuums, brushes, hand tools, and safe sealants to clean, repair, and insulate duct systems—delivering effective results without the need for advanced equipment.
We only use eco-safe, family- and pet-friendly disinfectants and sanitizers approved for residential use.
No hidden fees. No aggressive upsells. Just a clean, efficient duct system and results you can feel immediately.
If you’re experiencing any of these symptoms, it’s time for a full air duct evaluation.
Don’t let dirty or damaged ductwork compromise your comfort or your health. With AtticShield, you get clean air, improved efficiency, and total peace of mind—all backed by trusted professionals and proven results.

Your duct system moves the entire volume of air in your home several times every hour the HVAC runs. Whatever lives in the runs — dust, dander, spores, the leavings of pests — rides that circulation into every bedroom, every time. That is why duct condition punches so far above its visibility: you never see the runs, but you breathe their contents all day.
Ducts collect pollutants like pet dander, pollen, mold spores, and dust mites — and then circulate them through every room. Cleaning removes those contaminants at the source and supports a healthier, allergen-reduced environment.
Clogged or leaky ducts force your HVAC system to work harder. Clean, sealed ducts improve airflow and reduce strain — leading to lower energy bills and fewer breakdowns.
Moisture inside ducts promotes mold growth and foul odors. Removing moisture-trapping debris helps prevent mildew and bacteria buildup before it spreads.
Routine cleaning and prompt repairs reduce wear on your system’s components — helping you avoid expensive repairs or early equipment replacement.
Five steps, in an order that never changes — because cleaning ducts you have not inspected, or sealing ducts you have not cleaned, is how homeowners end up paying twice. Every step below is photographed, and the crew that runs it is the same in-house, family-operated team on every Attic Shield job — no subcontractors, no rotating strangers in your hallway.
A detailed inspection of your duct system to identify visible leaks, disconnected sections, blockages, and areas of contamination — photographed, so you see exactly what we see before any work is proposed.
We remove dust, debris, insulation fragments, and rodent contamination from accessible ductwork using contractor-grade brushes, vacuums, and hand tools — clearing the buildup and biological contaminants that restrict airflow and degrade indoor air quality, safely and thoroughly.
Where contamination exists, we apply EPA-registered disinfectants to kill bacteria, viruses, and fungi and neutralize lingering odors from rodent activity or dust buildup — only eco-safe, family- and pet-friendly products approved for residential use.
Cracked or leaky sections are repaired with professional-grade mastic sealants, reinforced insulation, or replacement materials to restore integrity and optimize airflow — and larger failures route honestly to the duct repair & replacement service rather than a patch that will not hold.
The system goes back on, and we verify airflow through the ductwork, confirm every connection is secure, and close with the before-and-after photo file — yours to keep.
Here is what most duct companies will not put on a sales page: the EPA advises that duct cleaning has never been shown to actually prevent health problems in every home, and recommends it specifically when there is visible mold, vermin infestation, or ducts clogged with excessive debris. We agree — and we build our recommendations on exactly those cases. It costs us jobs to say that on a sales page, and it earns us the right kind of customers: the ones who wanted a diagnosis, not a pitch.
So we will tell you straight at the inspection: if your ducts show rodent contamination, visible growth, construction debris, or years of measurable buildup, air duct cleaning is the right call and we will show you the evidence in photographs. If your real problem is duct leakage, crushed or disconnected runs, or missing insulation on the runs through a hot attic, cleaning alone will not fix your comfort or your bills — the fix is sealing, repair, or insulation, and we offer each as its own honest scope — the register was never the problem, the run through the 130-degree attic was. And if your ducts are simply fine? We will say that too, show you the photos, and shake your hand. The inspection is free either way — which is exactly what makes the honesty affordable.
This is where being an attic and crawl space specialist changes the job. Rodents use duct runs as highways and nesting shelter — and they leave behind droppings, urine, gnawed insulation, and sometimes chewed-open runs that dump your conditioned air into the attic. The CDC connects rodent waste to serious health risks, which is why contaminated ductwork is one of the clearest cases where cleaning and sanitization genuinely matter.
But cleaning contaminated ducts without closing the highway is a subscription, not a solution. Attic Shield pairs air duct cleaning with the exclusion work the problem actually requires: entry points sealed with 1/8-inch steel mesh or steel wool behind every closure — never foam alone — through the rodent proofing service, waste handled through rodent waste removal and sanitization, and the attic itself restored where nesting damaged insulation. One company, one sequence, one photo file — and the animals do not come back to re-dirty what you just paid to clean. If you have heard scratching in the vents at night, seen droppings near a floor register, or smelled that unmistakable ammonia note when the heat kicks on, start with the signs-of-rats guide — then book the inspection, because contaminated runs do not improve with time.
None of these symptoms proves the diagnosis by itself — that is what the photographs are for — but each one is your duct system asking for a look, and together they are how most of our air duct cleaning calls begin.
Ducts are out of sight by design, so they speak through symptoms. These are the seven we hear most on the phone:
If you’re experiencing any of these, it’s time for a full air duct evaluation — free, photographed, and honest about which symptom points to cleaning, which to sealing, and which to a different fix entirely. Two or more symptoms together — dust plus uneven rooms, odors plus noises — sharpen the case considerably; that combination usually means the system is both dirty and leaking, and the scope will show both, photographed.
Duct cleaning is a crowded market with a famous scam problem — the too-cheap ‘whole-house special’ that becomes a pressure pitch in your hallway. Our answer to that market is the same answer we give everywhere: a verifiable license, published methods, honest limits, and photographs. Six specifics:
Technicians experienced in industry-recommended cleaning methods, working to California code requirements, and skilled at identifying the duct system issues that hide behind symptoms.
Every system is different. Cleaning and repair plans are tailored to your duct layout, airflow issues, and indoor air quality concerns — never a one-size package. A 1962 ranch with original metal runs and a 2019 two-story with flex duct are different jobs, and their scopes should read like it.
Durable, contractor-grade vacuums, brushes, hand tools, and safe sealants — effective results, honestly delivered.
Only eco-safe, family- and pet-friendly disinfectants and sanitizers approved for residential use ever enter your system.
No hidden fees, no aggressive upsells, no same-day-only pricing — a written scope with photographs, and results you can feel immediately.
Ducts do not run through empty space — they run through your attic. We handle the sealing, insulation, and exclusion around them, so fixes actually hold.
The duct runs above your ceiling pass through one of the harshest environments in your home: an attic that bakes past 130°F all summer. Clean ducts that leak into that attic, or run through it uninsulated, still waste the air you paid to condition. That is why our duct work comes with the surrounding system in view: duct repair & replacement when runs are crushed, disconnected, or past saving; air duct insulation so conditioned air survives the attic crossing; attic air sealing so the ceiling plane stops leaking around the runs; and attic insulation brought to Title 24 depth so the whole assembly performs. ENERGY STAR guidance on duct sealing points the same direction: airflow you keep beats airflow you replace.
On the inspection we look at all of it — the ducts, the connections, the insulation on and around them, and any evidence of the rodent traffic that shortens all their lives. One visit, one photo file, one written scope with the now/later/fine-as-is columns. That is what ‘air duct cleaning near me’ should actually find: a company that sees the system, not just the symptom you searched. It is also why pairing services saves real money — when the attic is already under containment for insulation or rodent work, the ductwork is exposed, the protection is already down, and handling it in the same visit beats scheduling it twice.
Duct systems here do not age the way textbooks assume. From late spring through October, attic temperatures run past 130°F — heat that bakes flex duct, dries out old tape joints, and turns every small leak into money leaving through the roof. West of I-15, marine air works on metal runs and under-ventilated attics every month of the year, feeding the moisture that mold in ductwork needs. And the region’s roof rat pressure never takes a season off — mild winters and mature landscaping keep populations active, which is why duct contamination shows up here far more than homeowners expect.
The housing stock compounds it: pre-war homes with improvised runs, 1970s–80s tract systems with original ducts long past their design life, and newer construction where speed-built connections were never sealed to code. Each fails differently, and each is exactly why the inspection photographs your specific system before anyone proposes anything.
A duct evaluation is more than a flashlight in a register. The inspection walks the system end to end: connections at the plenum and boots, where leaks concentrate; kinked or crushed flex runs strangling airflow to the far rooms; failed support straps letting long runs sag and pool debris; the condition and coverage of insulation on runs crossing the hot attic; register and grille condition room by room; and every sign of pest traffic — droppings, gnaw marks, nesting material — that turns a cleaning job into an exclusion job.
Everything notable gets photographed, and the findings land in the same three-column written scope as every Attic Shield service: what needs attention now, what can wait, and what is fine as-is. You can hand that scope to any contractor and compare bids line by line — that is the point of it.
The same protection discipline as every job we run: floor runners and coverings down first, register areas protected, and containment at the work points so what comes out of your ducts never tours your living room. Registers come off and are cleaned individually; the runs are agitated and vacuumed with contractor-grade equipment; sanitization is applied where the inspection documented contamination; repairs and resealing follow; and the system is turned back on for the final airflow verification.
Most homes are done within a day, the HVAC system is only down while the work requires it, and the visit ends the way every Attic Shield job ends: a walkthrough with the before-and-after photographs, and a file copy for your records — useful for allergies you’re tracking, escrow disclosures, or simply proof the work you paid for actually happened.
