LC Heating & Air provides professional, NADCA-standard duct cleaning for Los Angeles homeowners. We use truck-mounted negative pressure systems to remove dust, wildfire smoke residue, and allergens from your entire HVAC system.
The air you breathe passes through your ducts dozens of times every day. In LA's dusty environment—with wildfire smoke, construction particulates, and heavy allergen seasons—duct contamination is a real issue. LC Heating & Air provides professional duct cleaning using truck-mounted negative pressure systems that remove years of accumulated dust, debris, and allergens from your entire duct system, not just the vents you can see.
I'm Leo, owner of LC Heating & Air. I believe in being honest about what your home actually needs. We don't push unnecessary services. If your ducts are clean, I'll tell you. If they are full of debris, I'll show you the proof with our before-and-after photos. We focus on the health of your system and the air quality in your home.

Why Los Angeles Duct Systems Need Special Attention
Los Angeles has specific duct contamination issues that make professional cleaning more important here than in many other cities. Wildfire events—more frequent and more severe in recent years—push fine particulate matter and combustion byproducts into home duct systems even when windows are closed, because HVAC systems draw outdoor air through gaps in the building envelope. We have performed post-fire duct cleaning for dozens of affected homeowners, and the before-and-after air quality measurements are striking. Standard filter replacement alone does not address contamination that has settled inside ducts and on coil surfaces.
Beyond wildfire smoke, LA's construction activity is a constant source of fine dust. If you have had any renovation work in or near your home, the duct system has almost certainly collected construction particulates. Older homes in neighborhoods with significant 1920s through 1950s housing stock often have galvanized steel ductwork that has accumulated decades of debris—dust, pet dander, pest droppings, and biological material from condensation that has occurred in duct sections over the years.
Our Diagnostic and Cleaning Process
We start with a system inspection. We use a camera to look inside your accessible ductwork to assess contamination levels and identify any damage or leaks. This is how we determine if cleaning is the right path or if you have structural issues that need repair first.
Next, we connect our truck-mounted vacuum to your main trunk line. This creates whole-system negative pressure. We then use rotary brushes and compressed air whips to dislodge debris while the vacuum captures it. We finish by cleaning the air handler interior, the evaporator coil, and the blower wheel. If we find mold or bacteria, we apply an EPA-registered sanitizer. Finally, we seal any duct leaks we found during the inspection.
Repairing vs. Replacing Your Ductwork
Sometimes, cleaning isn't enough. If your ducts are made of old, deteriorating flex duct that is collapsing or if the insulation is falling apart, cleaning might actually damage them further. In those cases, I will tell you that replacement is the better investment.
If the ducts are structurally sound but just dirty, cleaning is the right choice. We will always provide a written estimate and explain why we are recommending a specific path. You deserve to know the condition of your system before we start any work.
Health, Safety, and Asbestos
Safety is my priority. If your home was built before 1980, there is a risk that your duct insulation contains asbestos. Duct cleaning can disturb this material, which is a serious health hazard. We perform a visual inspection before starting any work. If we suspect asbestos, we will stop immediately. In that case, you will need professional asbestos testing and abatement before any cleaning can safely proceed.
Understanding Costs
Pricing for duct services depends on the size of your home and the complexity of your system. A standard duct inspection typically ranges from $125 to $200. A whole-house duct cleaning usually falls between $400 and $900. If we find leaks that need sealing, that service ranges from $1,000 to $3,000. For full duct repair or replacement, costs can range from $500 to $5,000 depending on the scope of work. We provide clear, written estimates so you know exactly what you are paying for.
Common Mistakes Homeowners Make
The biggest mistake is assuming that all duct cleaning is the same. Some companies use portable vacuums that just move dust around rather than removing it. We use truck-mounted equipment that provides true negative pressure. Another mistake is ignoring the air handler. If you clean the ducts but leave a dirty evaporator coil, you are still breathing in contaminants every time the system runs. We include the coil and blower wheel in our full service.
Frequently Asked Questions
Is duct cleaning worth it in Los Angeles? For homes with allergy sufferers, pets, post-renovation debris, or visible mold, yes. For a clean, well-maintained system, cleaning every 5–7 years is appropriate. We'll inspect and give you an honest assessment before recommending cleaning.
How long does it take? A typical 2,000 sq ft home with a single HVAC system takes 3–5 hours. Larger homes or multi-system homes take proportionally longer.
Do you clean dryer vents? Yes. Dryer vent cleaning is an important fire safety service. We clean dryer vents at the same time as duct cleaning for a package price.
Will it make my home smell better? Often yes, especially if there's pet dander, mold, or bacterial contamination. We apply EPA-registered sanitizer in cases of mold or bacteria for additional odor control.
Is It Time for a Cleaning?
Look for these signs: increased allergy symptoms, visible dust puffing from vents, or a musty smell when the system runs. If you have recently finished a remodel or have pets, you likely have significant buildup.
If you aren't sure, we can perform an inspection. We will show you the condition of your ducts and let you decide if cleaning is necessary. We don't believe in high-pressure sales—just honest, practical advice.

What Los Angeles customers say about duct cleaning
Verified reviews from homeowners in Los Angeles and nearby neighborhoods who used our duct cleaning service.
“Had LC install a Daikin mini split in our 1940s bungalow that never had AC. The work was clean, the unit is incredibly quiet, and our bedroom finally stays cool in summer. Highly recommend.”
“We converted our garage into an ADU and needed HVAC. LC installed a Mitsubishi single-zone mini split — permits, electrical, everything. The unit is so quiet you can barely hear it running. Our tenant loves it.”
“Got a 3-zone Daikin system for our craftsman home — bedrooms upstairs, living room downstairs. Each room has its own temperature control and the monthly electric bill is actually lower than our old window units combined.”
