What to expect from LC Heating & Air
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.
Overview
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. The 2025 Eaton Fire left particulate contamination throughout homes in Pasadena, Altadena, Arcadia, and neighboring communities. 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 Hollywood, Los Feliz, Silver Lake, and other 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.
LC Heating & Air's duct cleaning process follows NADCA (National Air Duct Cleaners Association) standards: we use truck-mounted negative pressure equipment combined with rotary brush agitation to dislodge and capture debris from the full duct system including trunk lines, branch runs, and boots. We also clean the air handler interior, the evaporator coil (if accessible), and the blower wheel — the components that recirculate everything that comes out of your ducts back into your living space. After cleaning, we photograph representative sections and provide before-and-after documentation.

What customers say about duct cleaning
Verified reviews from Los Angeles homeowners who used our duct cleaning service.
“After the Eaton Fire, our ducts smelled like smoke. LC did a full cleaning — negative air pressure, rotary brushes, the works. Air quality in our home is completely different now. They were sensitive to what our neighborhood went through.”
“Our furnace wasn't heating evenly upstairs. LC found that half of our ductwork in the attic had separated and was blowing hot air into the attic. Repaired everything and now every room heats equally. Professional and transparent.”
“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.”
