Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterWhy Los Angeles Homeowners Choose Trane Air Duct Cleaning
We provide independent Trane service in Los Angeles, and our diagnostic-first approach is built around Trane’s specific cabinet, coil, and plenum geometry rather than generic one-size-fits-all cleaning. From XR14 straight-cool units in San Fernando Valley tract homes to XV20i variable-speed heat pumps in Pasadena, we know how Trane ductwork loads and airflow actually behave in real LA homes. Morton’s Air Duct Cleaning is an independent service provider, not affiliated with or authorized by Trane, but we work on their systems every day. Call (323) 918-4345 for a written estimate before any work begins.
Why Trust Morton’s Air Duct Cleaning for Your Trane Air Duct Cleaning
Paul Adeyemi, our owner, grew up in Inglewood and studied HVAC fundamentals and indoor air quality at Los Angeles Trade-Technical College before spending the better part of two decades working inside the walls of homes across the LA basin. That hands-on grounding in ventilation mechanics shapes how our technicians approach every Trane repair in Long Beach and across the LA basin. We understand that a Trane XR15 in a Silver Lake Spanish Revival with retrofitted duct runs behaves differently from the same unit in a 1960s Crenshaw tract home with fiberglass duct board crammed into a low-clearance attic. Our technicians are background-checked, uniformed, and trained to work to the Cedarwell C.A.R.E. values on every job. That means shoe covers and drop cloths go down before tools come out, and you get a written price before any work starts. We also carry OEM Trane filters, gaskets, and access panels where fit matters, paired with quality aftermarket flex duct, mastic, and insulation on the runs themselves. As independent technicians, we make repair and replacement calls based on what we find, not what earns us the highest margin.
Common Trane Air Duct Cleaning Problems We Fix in Los Angeles
Trane builds a durable system, but Los Angeles conditions test even the best equipment. Here are the issues we see most often, tied directly to Trane’s specific designs:
- Factory-sealed plenums loosening at the air handler. Trane factory-seals plenums with gaskets and mastic at installation, but years of thermal expansion and attic heat cycles dry those seals out. When the gasket separates, attic dust and insulation fibers get pulled into the return before the filter ever sees them. In neighborhoods like Brentwood and Pacific Palisades after the January 2025 Palisades and Eaton fires, that dust carried ash containing heavy metals and combustion VOCs from burned structures, requiring documentation for insurance claims that most contractors outside a wildfire-prone basin never encounter.
- All-aluminum spine-fin evaporator coils loading with lint and dust. Trane’s signature spine-fin coil is efficient, but the tightly packed aluminum fins trap lint and fine dust on the fin face. In coastal and valley air, that accumulation chokes airflow and raises static pressure across the coil. We see this constantly on XR14 and XR15 systems in the South Coast Air Basin, where seasonal temperature inversions from June through September concentrate particulate matter and the dry Mediterranean season from May through October puts heavy dust into return vents with no rain to settle it.
- ECM blower wheels accumulating fine dust unevenly. Trane’s newer ECM blower motors are quiet and efficient, but their blower wheels collect fine dust unevenly on the blades. That imbalance causes vibration owners hear as a low rumble through the return grille. On variable-speed systems like the XV18 and XV20i, the blower ramps through multiple speeds, which can make the imbalance more noticeable at certain RPMs. We hand-clean the blower wheel rather than blasting it with air, which keeps the balance intact.
- Oversized condenser pads paired with undersized returns creating high return-side static. This is a Trane-specific mismatch we see regularly in Los Angeles. Homeowners replace an aging unit with a larger Trane condenser, but the original return duct stays the same size or gets partially blocked by years of debris. The result: branches nearest the air handler starve for air while far rooms get poor airflow. Los Angeles housing stock makes this worse because the San Fernando Valley, Inglewood, and Crenshaw corridors are dominated by 1950s-1970s post-war tract homes where central HVAC was retrofitted years after construction, with aging flex duct or deteriorating fiberglass duct board crammed into attic spaces never designed for those runs.
- Coil pitting and heat exchanger wear in coastal and wildfire-adjacent zones. In neighborhoods close to the coast or downwind of wildfire zones, Trane coils can show pitting from corrosive particulate exposure. When a Trane coil is pitted or a heat exchanger is cracked, we say so plainly instead of sealing it and calling it cleaned. The repair-vs-replace call belongs to the owner, not the upsell.
Trane Parts and Our Repair-vs-Replace Approach
We use OEM Trane filters, gaskets, and access panels where fit matters. Trane’s cabinet dimensions and plenum geometry are precise, and aftermarket access panels rarely seal as tightly as the factory parts. On the duct runs themselves, we use quality aftermarket flex duct, mastic, and insulation. That’s where the aftermarket products perform just as well, and they save you money without sacrificing the seal integrity. When a Trane coil is pitted or a heat exchanger is cracked, we tell you plainly. No sealing over a failing part and calling it cleaned. The repair-vs-replace decision belongs to you, and we lay out the costs and expected service life for each path before you commit. For an exact quote on your Trane system, call (323) 918-4345.

Our Trane Service Process, Step by Step
- 1
Diagnosis. We inspect the Trane air handler cabinet, plenum connections, coil face, and blower wheel. We measure static pressure across the coil and filter to identify where airflow is choking. Before we start, let me show you exactly what we found and exactly what it will cost to fix it.
- 2
Repair and clean. We hand-clean the Trane evaporator coil face and ECM blower wheel rather than blasting them with compressed air, which can damage the spine-fin coil and unbalance the blower. We mastic-seal and re-tape the plenum and branch collars where the factory gaskets have dried and separated.
- 3
Duct sealing. On Trane systems with aging flex duct or deteriorating fiberglass duct board, we seal accessible runs with mastic and replace damaged sections. This reduces leakage that pulls attic air into the return before the filter.
- 4
Test. We measure static pressure before and after the work so you can see the improvement in writing. We run the system through a full cooling or heating cycle and verify airflow at registers throughout the house.
- 5
Warranty and documentation. Every job is backed by the 365-Day Done Right Promise. If it’s not done right, we make it right. And before the crew leaves, we take a photo of the clean-up so you have visual proof the house is left better than we found it.
Trane Products We Service and Install in Los Angeles
We service the full Trane residential line across Trane in San Diego and Los Angeles, from the XR14 and XR15 split systems to the XR17 and variable-speed XV18 and XV20i heat pumps. We also work on Trane S-Series furnaces including the S8X1, S8X2, and S9V2, plus Trane Tempo and RunTru by Trane builder-grade packages. We carry OEM Trane filters and access panels locally for faster turnaround, and we stock quality aftermarket flex duct, mastic, and insulation for the runs. Whether you have a matching Trane condenser and furnace or a mixed system, our technicians know the geometry and airflow behavior to expect.
We Also Service These Brands
Trane is a significant part of our work in Los Angeles, but it’s not the only brand we know well. We also service Lennox and Carrier systems, which gives us perspective on how Trane’s coil, blower, and plenum designs compare to their major competitors. That broader experience helps us diagnose Trane issues faster because we understand what’s unusual about a Trane system versus what’s common to all residential HVAC.
FAQs: Trane Air Duct Cleaning Service in Los Angeles
Yes, when the uneven cooling is caused by return-side static pressure or a blocked coil. On a Trane XR15 in a Los Angeles home, the most common culprits are a dried plenum gasket at the air handler pulling attic dust into the return, an all-aluminum spine-fin coil loaded with lint and dust, or branches nearest the air handler starving while far rooms get poor airflow. We measure static pressure across the coil and filter before and after cleaning so you see the improvement in writing. If you’re not sure what’s causing the uneven cooling, call (323) 918-4345 for a diagnostic visit with a written estimate.
Yes. Trane’s spine-fin coil has tightly packed aluminum fins that are efficient but easy to bend with compressed air or aggressive brushing. We hand-clean the coil face with soft brushes and low-pressure rinsing, which removes the lint and dust without flattening the fin surface. Hand-cleaning takes longer, but it protects the coil you already paid for. Call (323) 918-4345 to schedule a Trane coil inspection.
No. Before we start on an attic air handler, we seal off the return and supply registers inside the house and run the system with a high-efficiency filter in place during the cleaning. Our technicians lay down drop cloths along the attic access path and work with shoe covers. The dust we dislodge stays in the attic and gets vacuumed out through our Rotobrush and Nikro collection equipment, not pushed into your living space. In Los Angeles, where many Trane air handlers sit in low-clearance attic spaces, this containment matters more than in homes with basement or closet installations.
We stock and install OEM Trane filters because their dimensions and sealing edges match the factory cabinet precisely. Aftermarket filters with the same nominal size often sit slightly looser in the filter track, letting air bypass the media. That bypass is exactly what we’re trying to eliminate when we clean a Trane system. If you prefer a specific aftermarket filter media, we’ll work with you to find one that seals correctly in your Trane cabinet.
Yes. Warranty coverage for Trane equipment is handled by Trane’s own warranty terms, and having an independent service provider clean the ducts does not void the manufacturer’s equipment warranty. Morton’s Air Duct Cleaning is not affiliated with or authorized by Trane, but we follow warranty-safe service practices: we use OEM Trane parts where fit matters and we never modify the air handler, coil, or blower assembly in ways that would affect warranty eligibility. If you have a specific Trane warranty question, call (323) 918-4345 and we’ll walk through what we can and can’t do safely within your coverage.
Trane in Fresno and Los Angeles air duct cleaning typically costs $450 to $900 for a full system clean, depending on the size of the home, the number of runs, and the condition of the plenum and coil. A full system clean on a 3-4 bedroom Los Angeles home with a Trane XR14 or XR15 and matching air handler usually falls in the $500 to $750 range. Evaporator coil cleaning added to a duct cleaning typically runs $150 to $300. Duct sealing, when the Trane plenum and branch collars need mastic work, adds $200 to $500 depending on how many connections need attention. We provide a written price before any work starts, so you’ll know the exact number before we touch anything. Call (323) 918-4345 for a free estimate on your specific Trane system.
