LC Heating & Air provides professional, NADCA-standard duct cleaning for Pasadena homes. We use truck-mounted negative pressure to remove contaminants, not just move them around.
Pasadena's climate and housing stock create unique challenges for indoor air quality. From the historic craftsman homes in Bungalow Heaven to modern condos downtown, your ductwork acts as the lungs of your home. When dust, wildfire smoke, or construction debris settles inside your ducts, your HVAC system recirculates those particles every time it cycles on.
At LC Heating & Air, we don't believe in 'surface-only' cleaning. We use truck-mounted negative pressure systems to pull debris out of your entire system—trunk lines, branch runs, and the air handler itself. If you are noticing musty odors, increased allergy symptoms, or visible dust, we are here to help you get your home's air back to where it should be.
Local HVAC considerations
We specialize in working around the constraints of Pasadena's landmark districts and historic architecture.
We are experienced in coordinating with HOAs and managing access in dense, multi-family, and mixed-use buildings.
Pasadena's 100-degree summer days require systems that are clean and efficient to prevent equipment failure.
Why Pasadena Ducts Need Professional Attention
Pasadena faces specific environmental stressors that impact your ductwork. Wildfire events frequently push fine particulate matter into homes, and local construction activity keeps a constant layer of fine dust in the air. If you have recently remodeled or live in an older home with galvanized steel ducts, you likely have decades of accumulated debris.
We often see systems where the air handler coil is clogged with dust, which forces the blower motor to work harder and reduces cooling efficiency. Our process cleans the supply and return ducts, the air handler interior, and the blower wheel, ensuring your system isn't just pushing dirty air around your living space.
Repair, Clean, or Replace?
Duct cleaning is a maintenance service, not a repair for a broken system. If your ducts are physically damaged, leaking, or crushed, cleaning won't fix the airflow issues. We always perform a camera inspection first to see if the ducts are intact.
If we find significant mold, rodent infestation, or structural damage during our inspection, we will be honest with you about whether cleaning is sufficient or if sections need to be replaced. We don't sell services you don't need; we provide the information you need to make the right choice for your home.
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
- • Total square footage of the home
- • Number of HVAC systems and zones
- • Accessibility of ductwork (attics, crawlspaces, or tight closets)
- • Level of contamination (mold, pet dander, or construction debris)
- • Need for additional services like dryer vent cleaning or duct sealing

What Pasadena customers say about duct cleaning
Verified reviews from homeowners in Pasadena and nearby neighborhoods who used our duct cleaning service.
“AC wasn't cooling to setpoint even though it was running all day. LC found the condenser coils were completely clogged with cottonwood. Cleaned them on the spot and the system cooled my house 12 degrees in an hour.”
“LC replaced our entire HVAC system — new Carrier condenser, furnace, and coil. Leo walked us through every option without pressure. The install team was professional and clean. System runs perfectly and our electricity bill dropped about 30%.”
“Called LC because our CO detector went off. Their technician found a crack in the heat exchanger and immediately shut down the furnace. He explained the safety issue clearly, provided a replacement estimate, and didn't try to scare us — just facts.”
