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.

AfterFast, Reliable Air Duct Cleaning Across West Covina
Air duct cleaning in West Covina typically runs $350-$650 for a full residential system, with most jobs completed in a single morning or afternoon. If your home was built during the 1950s boom, there’s a good chance your original ductwork needs more than a surface clean. Call Morton’s Air Duct Cleaning at (323) 918-4345 for a free written estimate before any work starts.
We’ve been serving West Covina families since 2005, and our crews know the difference between a postwar ranch off West Workman Avenue and a split-level near South Hills Country Club. The San Gabriel Valley’s basin geography hits these homes harder than most. Mountains trap smog against the eastern edge of the city, and Santa Ana winds push Mojave Desert grit straight through the Pomona corridor. Your ducts work overtime here. That’s why our Air Duct Cleaning team doesn’t just vacuum out registers and call it done. We inspect, we clean, and we seal - because in West Covina, sealing is usually where the real fix lives.
Scheduling and dispatch run from our Los Angeles office, but the crew that pulls into your driveway knows West Covina’s housing stock and its problems. They bring shoe covers, drop cloths, and quiet tools for nap time. They also bring a written price, agreed before anyone touches your system.
Why Morton’s Air Duct Cleaning Is West Covina’s Preferred Air Duct Cleaning Company
West Covina homeowners call us back because we treat their houses like homes, not job sites. Our technicians are background-checked, uniformed, and trained to the Cedarwell C.A.R.E. values - that means shoe covers before they cross your threshold, drop cloths under every tool bag, and pet-safe product choices where they’ll do the job without stressing your animals.
Every visit starts with a written price. No exceptions. We’ve heard too many stories from families in the Woodside Village area and near Galster Wilderness Park who got a low teaser quote that ballooned once the crew was inside. That doesn’t happen here. One flat price per system, agreed upfront, with no per-vent add-ons.
The 365-Day Done Right Promise backs every job. If something isn’t right, we make it right. Full stop. And before our crew leaves, they take a photo of the clean-up so you can see your floors, furniture, and registers exactly as we found them - or better.
A live person answers our phones 24/7. Not a chatbot, not a voicemail tree. A real human who can schedule your appointment or answer questions about what to expect.
Air Duct Repair in West Covina
Air Duct Repair in West Covina usually means fixing the damage that sixty or seventy years of use, heat cycling, and particulate load have inflicted on original 1950s duct systems. We find crushed flex runs behind drywall, disconnected trunk lines in attics where mastic has turned to dust, and delaminated fiberglass duct board that leaks conditioned air into crawl spaces instead of your bedrooms. A typical repair call in West Covina runs $200-$550 depending on accessibility and material, though full trunk-line replacement on a large ranch home can reach $1,200-$2,000.
Disconnected Runs and Failed Mastic
Original sheet-metal trunk lines in West Covina ranch homes were sealed with fabric-and-mastic joints that crack after decades of thermal expansion. We open the plenum, locate the separation with a video scope, and reconnect with modern foil tape and water-based mastic rated for the temperature swing your attic sees in August.
Duct Board Delamination
Early fiberglass duct board swells and separates when it absorbs moisture from humid summer air or condensate pan overflow. Once the interior liner bubbles away from the fiberglass core, cleaning alone won’t fix it. We cut out the damaged section and splice in new duct board or transition to sheet metal, depending on your system’s layout.
Ductwork Cleaning in West Covina
Ductwork Cleaning in West Covina addresses the particulate buildup that basin-trapped smog, Santa Ana wind grit, and decades of household dust have layered inside your system. A full residential cleaning runs $350-$650 for most West Covina homes, with larger systems or heavy contamination reaching $750-$950. Commercial ductwork starts around $800 and scales with square footage and access difficulty. Every quote is written and agreed before we start.
Source Removal with HEPA Containment
We set up negative pressure using an Abatement Technologies portable HEPA filtration unit before any agitation begins. This captures dislodged debris at the source instead of letting it migrate into your living space. Our Rotobrush system scrubs the interior of round ductwork while the Nikro vacuum pulls loosened material out through a sealed hose.
Register and Plenum Detail Work
Supply registers and return plenums in West Covina homes often show the heaviest accumulation because that’s where airflow changes direction and particles drop out. We remove each register, clean the boot and surrounding drywall or floor cavity, and treat the plenum with contact vacuuming and brushing before reassembly.
Trusted Brands We Service in West Covina
Our vans carry professional-grade equipment from Honeywell, Aprilaire, and Abatement Technologies - not rental-shop gear that loses suction halfway through a job. For West Covina homeowners with older systems, this matters because 1950s-era ductwork needs careful handling. A too-aggressive brush or undersized vacuum can damage brittle fiberglass or pull loose already-failing mastic joints. We match the tool to the material, and we stock common fittings and sealing supplies so most repairs finish same-visit without waiting for parts to ship. If your system uses Honeywell media filters or Aprilaire whole-house air cleaners, we service those during the same appointment and can show you how the clean ductwork changes their load cycle.
Common Air Duct Cleaning Problems We See in West Covina Homes
- Delaminated fiberglass duct board in original 1950s ranches. The interior liner separates from the fiberglass core, creating a rough surface that traps dust and releases fibers into airflow. Cleaning without repair just postpones the problem.
- Carbon-tinged soot accumulation near I-10 corridor homes. Slab-on-grade houses with unsealed under-slab returns pull diesel particulate from freeway air. Standard surface cleaning won’t touch it; agitation with proper source removal is required.
- Disconnected supply runs behind finished ceilings. Thermal expansion and rodent activity in older attics knock flex ducts off collar connections. Homeowners notice weak airflow to specific rooms, not knowing conditioned air is dumping into the attic.
- Heavy PM2.5 and grit loading from Santa Ana wind events. After major wind episodes, we find measurable desert sand in return plenums. Without concurrent air handler and blower motor cleaning, that grit recirculates within weeks.
Pricing for Air Duct Cleaning in West Covina, CA
Here’s what honest pricing looks like for Air Duct Cleaning in West Covina:
| Service | Typical Range |
|---|---|
| Residential full system cleaning | $350-$650 |
| Large home or heavy contamination | $750-$950 |
| Commercial duct cleaning | $800-$2,500+ |
| Air duct repair (typical) | $200-$550 |
| Full trunk-line replacement | $1,200-$2,000 |
| Dryer vent cleaning (add-on) | $120-$180 |
What moves the needle? System size, contamination level, and access. A single-story ranch with an attic air handler costs less than a two-story with ducts buried in soffits. Homes near the I-10 with heavy soot infiltration need more contact time and HEPA filtration, which we build into the upfront quote. We don’t bait with a low number and add per-vent charges later. One flat price per system, written down, agreed before work starts. Call (323) 918-4345 for your exact estimate - they’re free, and we’ll explain what we expect to find before we schedule.

FAQs About Air Duct Cleaning in West Covina
West Covina’s position at the eastern end of the San Gabriel Valley basin means mountains trap smog and Santa Ana winds funnel Mojave dust through the Pomona corridor directly into this area. Your ducts accumulate PM2.5 and grit at rates that coastal or western-valley cities simply don’t see, so cleaning schedules that work in Pasadena or Santa Monica fall short here. Most West Covina families with kids or allergies benefit from inspection every two to three years rather than the five-year cycle common elsewhere. Call (323) 918-4345 to discuss your home’s specific load.
Expect original sheet-metal trunk lines with deteriorating mastic joints, or early fiberglass duct board that has cracked and delaminated after sixty to seventy years of thermal cycling. We find disconnected runs, collapsed flex sections, and significant leakage on most 1950s West Covina service calls. Cleaning without camera inspection and subsequent sealing usually wastes money because conditioned air keeps leaking into attics and crawl spaces. Our written quote includes what we find and what it costs to put right.
Homes within roughly a half-mile of the San Bernardino Freeway show noticeably darker, carbon-tinged particulate accumulation in return ducts compared to similar-aged homes elsewhere in the SGV. Slab-on-grade construction with unsealed under-slab returns pulls diesel soot directly into the system. A standard surface wipe-down misses this layer entirely. We use agitation tools and proper source removal with HEPA containment to dislodge and capture it. If you live near the freeway corridor, mention it when you call (323) 918-4345 so we plan the right equipment.
Yes, our procedures align with NADCA ACR guidelines for source removal, negative pressure containment, and post-cleaning verification. We use Abatement Technologies HEPA equipment and Rotobrush mechanical agitation that meets NADCA-recommended contact vacuuming standards. For West Covina’s older housing stock, we also exceed minimum scope by including visual inspection of accessible joints and plenum condition, since original 1950s materials often need repair beyond standard cleaning parameters.
Uneven temperatures between rooms, weak airflow at distant registers, or a blower motor that runs constantly without reaching setpoint usually mean disconnected or leaking ducts, not just dirty ones. We bring a video scope to every West Covina appointment and can show you the condition of your trunk lines before we quote either cleaning or repair. The photo of your clean-up that we take before leaving includes any repair documentation so you have a record. Call (323) 918-4345 and we’ll schedule an inspection.
We answered a call off South Azusa Avenue near the I-10 corridor, where the homeowner’s return ducts showed that familiar carbon-tinged diesel soot film that slab-on-grade West Covina homes pull in from the freeway. After setting up negative pressure with our Abatement Technologies HEPA unit and running a Rotobrush through the 60-year-old sheet-metal trunk lines, we found two disconnected runs in the original duct board that had delaminated - we reconnected and sealed them with mastic, and the blower motor amp draw dropped noticeably by the time we buttoned up the air handler.
