LC Heating & Air provides NADCA-standard duct cleaning for Los Feliz homes, removing years of accumulated dust, allergens, and wildfire particulates using powerful truck-mounted negative pressure systems.
Los Feliz is one of the most architecturally distinct neighborhoods in Los Angeles, home to a dense concentration of 1920s and 1930s Spanish Colonial Revival and Mediterranean-style homes. These properties often feature original plaster walls and complex architectural details that make HVAC maintenance and ductwork routing genuinely challenging. I am Leo, owner of LC Heating & Air, and my team and I have spent two decades working in these homes, understanding exactly how to handle the unique requirements of older construction.
The air you breathe passes through your ducts dozens of times every day. In our dusty environment—compounded by wildfire smoke, construction particulates, and heavy allergen seasons—duct contamination is a real issue. We provide professional duct cleaning using truck-mounted negative pressure systems that remove years of accumulated debris from your entire system, not just the vents you can see. We follow NADCA standards for source removal, ensuring we clean the supply and return ducts, the air handler interior, and the evaporator coil.

Duct Contamination in Los Feliz
Los Angeles has specific duct contamination issues that make professional cleaning more important here than in many other cities. Wildfire events 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 many homeowners, and the before-and-after air quality measurements are striking.
Beyond wildfire smoke, LA's constant construction activity is a source of fine dust. If you have had any renovation work in or near your home, your duct system has almost certainly collected construction particulates. Older homes in Los Feliz 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.
Challenges of Older Los Feliz Homes
Los Feliz's older housing stock presents three consistent HVAC challenges: original ductwork that is undersized for modern comfort expectations, plaster-and-lath construction that complicates new duct runs, and hillside lots with limited space for outdoor condenser placement. We use flexible installation approaches including mini-split systems for rooms that cannot be served efficiently by a central duct system.
Many homes here have partially original duct systems—galvanized steel trunk lines combined with flex duct extensions added in various decades. This patchwork ductwork is a common source of efficiency problems, hot and cold spots, and duct leakage. We assess the full duct system during every project and recommend consolidation or replacement when the existing ductwork would significantly compromise new equipment performance.
Our Cleaning Process
We don't believe in surface-only cleaning. Our process starts with a system inspection where we use a camera to assess contamination levels and identify any damage or leaks. We then connect our truck-mounted vacuum to the main trunk to create whole-system negative pressure, which ensures debris is captured rather than redistributed throughout your home.
Our technicians use rotary brushes and compressed air whips to dislodge debris while the vacuum pulls it out. We also clean the air handler interior, the evaporator coil, and the blower wheel. Finally, we apply an EPA-registered sanitizer if mold or bacteria is present and seal any duct leaks found during our inspection.
Repair or Replace?
If the system is worth repairing, we will tell you. If the pattern points to replacement, we will explain why. Duct cleaning is often a maintenance task, but if we find that your ductwork is severely damaged, undersized, or leaking beyond repair, we will provide an honest assessment of whether a repair is sufficient or if a full replacement is the better long-term investment for your home's efficiency.
The estimate should make sense before anyone touches the equipment. We provide written estimates and clear explanations of what we find so you can make an informed decision based on the actual condition of your ducts.
Understanding Costs
Duct cleaning costs vary based on the size of your home and the complexity of your duct system. A typical 2,000 sq ft home with a single HVAC system usually takes 3–5 hours. We offer transparent pricing for our services, including duct inspection ($125–$200), whole-house duct cleaning ($400–$900), and duct sealing ($1,000–$3,000).
We also offer dryer vent cleaning, which is an important fire safety service. We can bundle this with your duct cleaning for a package price. Every project is unique, so we provide a detailed estimate after our initial inspection.
Scheduling and Access
Our Fairfax Avenue base puts us 15 to 20 minutes from Los Feliz under normal traffic. We understand that hillside homes and narrow roads require careful planning for equipment placement and service clearances. When you schedule with us, we account for these logistics to ensure we arrive prepared to do the job right the first time.
We prioritize clear communication regarding our arrival window and the scope of work. Whether you are in the Los Feliz Hills, Laughlin Park, or along the Rowena Corridor, we are equipped to handle the specific access challenges of your property.
Health and Safety Considerations
If your home was built before 1980, there is a possibility of asbestos duct insulation. We perform a visual inspection before starting any work and will stop immediately if we suspect asbestos. In such cases, professional abatement must be completed before we can proceed with cleaning.
Duct cleaning can help reduce allergy symptoms by removing dust mites, pet dander, mold spores, and pollen. For the most comprehensive allergen reduction, we recommend combining duct cleaning with a quality air filter and a UV air purifier. We are committed to improving your indoor air quality safely and effectively.
Common Duct Myths
A common mistake is assuming that changing your air filter is the same as cleaning your ducts. While filters are essential, they do not remove the debris that has already settled inside your ductwork or on your evaporator coil. Another mistake is relying on 'cheap' cleaning services that only use portable vacuums; these often redistribute dust rather than removing it from the home.
We believe in doing the job right. We provide before-and-after photos so you can see exactly what we removed from your system. This transparency is part of our commitment to being an honest, local contractor.
Is Duct Cleaning Right for You?
Duct cleaning has the most value when dust, smoke residue, renovation debris, odor, poor filtration, or visible contamination is actually present. If you notice visible dust puffing from vents when the system starts, or if you experience increased allergy symptoms at home, it is time for an inspection.
For a clean, well-maintained system, cleaning every 5–7 years is appropriate. We will inspect your system and give you an honest assessment before recommending any work. If your ducts are clean, we will tell you.
How the visit works
We inspect accessible ductwork with a camera to assess contamination levels and identify any damage or leaks.
Our truck-mounted vacuum connects to the main trunk to create whole-system negative pressure.
Technicians use rotary brushes and compressed air whips to dislodge debris while negative pressure captures it.
We apply EPA-registered sanitizer if mold or bacteria is present and seal any duct leaks found during inspection.
Cost factors we review before quoting
- • Square footage of the home
- • Number of HVAC systems
- • Accessibility of ductwork in hillside properties
- • Presence of mold or heavy biological contamination
- • Requirement for duct sealing or minor repairs

What Los Feliz customers say about duct cleaning
Verified reviews from homeowners in Los Feliz and nearby neighborhoods who used our duct cleaning service.
“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.”
“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.”
