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.

Why Morton’s Air Duct Cleaning Is San Marcos’s Preferred Dryer Vent Cleaning Company
We’ve been part of the Cedarwell family since 2005, and our approach hasn’t changed: background-checked, uniformed technicians, shoe covers and drop cloths on every visit, and a written price before anyone touches your dryer. San Marcos homeowners know us for working around real life - nap schedules, dogs underfoot, the chaos of a Tuesday afternoon laundry room. Our Dryer Vent Cleaning team uses professional Rotobrush and Nikro equipment, not rental-shop gear, and every job ends with a photo of the clean-up before we leave. The 365-Day Done Right Promise applies to every visit. If something’s not right, we make it right. Full stop.
Dispatch and scheduling are coordinated from our Austin office, but the crew that arrives at your San Marcos door knows the area. They know which Rancho Coronado floor plans have the long horizontal runs that sag over time, and which San Elijo Hills elevations catch the worst Santa Ana wind loading on exterior vent hoods. That local familiarity means faster diagnosis and no guesswork on your bill.
Dryer Vent Cleaning Service in San Marcos
Dryer Vent Cleaning Service in San Marcos starts with a full inspection of the vent run from the back of your dryer to the exterior hood, because in this city the problem is rarely just the lint trap. We use Rotobrush whip systems and Nikro high-velocity vacuums to clear the entire pathway, then run a camera to check for crushed or disconnected flex behind the wall - a failure mode we see constantly in 1990s-2000s tract homes where the original builder used cheap flex duct strapped too tight or routed through awkward framing.
A typical Dryer Vent Cleaning Service in San Marcos runs $150-$225 for a straightforward clean with accessible vent runs. If we find a crushed or disconnected section behind the laundry wall, reconnection and sealing runs $75-$150 additional, and we’ll show you the camera footage before you decide. Every price is written and signed before work starts.
What We Clear From San Marcos Vent Runs
The inland valley position of San Marcos means our crews regularly pull a distinctive fine ochre-tan desert dust mixed with charred chaparral debris from dryer vents - material that blows in during Santa Ana wind events even through closed windows. This packs into the lint pathway alongside normal fiber accumulation, and it doesn’t respond to a shop-vac or a brush-on-a-stick from the hardware store. Our equipment is built for this.
Camera Inspection Included
Every cleaning includes a camera pass of the full run. We want you to see what we see: the buildup, any crush points, whether the exterior flapper actually opens under dryer pressure. That footage becomes part of your record, and it’s how we catch the disconnected runs that vent lint into your wall cavity instead of outside.
Dryer Vent Installation in San Marcos
Dryer Vent Installation in San Marcos addresses the root problem when the original 1990s-2000s flex duct has failed beyond cleaning - crushed, torn, or disconnected behind the laundry wall where patching isn’t safe or durable. We replace with rigid or semi-rigid metal ducting to code, properly supported and sealed, with a new exterior hood and flapper sized for your dryer’s CFM rating. A standard reroute or replacement in San Marcos runs $275-$450 depending on run length, wall penetration needs, and whether we’re working with a slab or raised foundation.
Homes in San Elijo Hills and Twin Oaks Valley Ranch often have the dryer on an interior wall with a long horizontal run to an exterior gable. These configurations sag, collect moisture, and crush where they pass through framing. We re-route to minimize bends, add proper support straps every 4 feet, and terminate with a pest-resistant hood.
Bird Guard and Pest Protection
San Marcos’s chaparral interface means birds, wasps, and rodents investigate vent hoods year-round. We install Guardsman-brand bird guards and replacement vent caps with proper backdraft dampers that still allow full airflow. A bird guard add-on runs $45-$85 installed.
Code-Compliant Materials
We don’t reinstall flex duct for dryer vents. The job gets rigid aluminum or galvanized steel, foil-taped seams, and proper clearances from combustibles. That’s the standard, and it’s what we document with photos before we leave.
Trusted Brands We Service in San Marcos
Our San Marcos crews carry professional equipment from Rotobrush, Nikro, and Guardsman - brands built for residential duct and vent work, not weekend rental projects. We stock common vent caps, bird guards, and transition fittings locally so most installations finish same-visit without a parts run. For homes with integrated Honeywell or Aprilaire ventilation systems, we coordinate dryer vent work so nothing compromises the balanced airflow those systems depend on. Every tool is cleaned between jobs, and we use drop cloths and shoe covers from the moment we enter, because your floors matter as much as your vents.
Common Dryer Vent Cleaning Problems We See in San Marcos Homes
- Crushed original flex behind the laundry wall. In Rancho Coronado and San Elijo Hills homes built 1995-2005, the dryer vent was often strapped with the same cheap flex duct as the HVAC. Decades later it’s flattened where it passes through studs, creating a lint trap inside the wall cavity that the homeowner can’t see or reach.
- Santa Ana dust caking the exterior flapper. The inland valley funnels Mojave desert dust straight into San Marcos vent hoods during fall and winter wind events. The flapper sticks at half-open, back-pressure builds, and dry times stretch from 45 minutes to two cycles.
- Post-Lilac Fire ash residue in Twin Oaks Valley Ranch and San Elijo Hills. After the 2017 fire, ash and smoke particulate coated exterior vent hoods and worked into the lint pathway. It’s a distinctive gray film that standard lint doesn’t match, and it reduces airflow in ways pure fiber buildup doesn’t.
- Long horizontal runs sagging toward the middle. Master-planned communities here favored interior laundry rooms with 15-25 foot runs to the nearest exterior wall. Without proper support, these low spots collect moisture and lint, accelerating blockage and creating a fire risk at the sag point.

FAQs About Dryer Vent Cleaning in San Marcos
The clearest sign is a dryer that still runs hot and slow even after you’ve thoroughly cleaned the lint trap and the accessible transition duct behind the machine. If the exterior hood flapper barely lifts during a cycle, or if you feel hot, humid air collecting in the laundry room instead of exhausting outside, the run is likely obstructed or disconnected behind the wall. Our camera inspection finds this in about 30 percent of San Marcos tract homes built 1995-2005. Call (323) 918-4345 and we’ll confirm exactly what’s happening before you commit to any work.
San Marcos’s inland valley geography puts you in the direct path of Santa Ana wind events that coastal Carlsbad largely avoids. From October through March, those 30-60 mph offshore winds pull fine Mojave desert dust and chaparral particulate into exterior vent hoods, where it mixes with lint and cakes the flapper mechanism. Coastal cities get marine layer moisture that keeps some particulate settled; San Marcos gets the dry blast straight from the desert. That dust loading is real, it’s measurable, and it’s why we see denser packed material in San Marcos vents than in coastal North County jobs. More frequent professional cleaning - typically every 12-18 months here versus 18-24 months at the coast - keeps airflow where it should be.
We follow NADCA guidelines for duct and vent cleaning, and our equipment is professional-grade Rotobrush and Nikro systems - not shop-vacs, not drill-mounted brush kits from the hardware store. That means source-removal agitation, contained high-velocity vacuum collection, and camera verification of the complete run. A shop-vac can clear the first few feet from the hood; it can’t address a crushed flex section 12 feet inside the wall or pull two gallons of packed desert dust from a low sag point. The difference shows in dry times, energy bills, and safety.
It depends on what the camera shows. If the flex duct is intact with no tears, crush points, or disconnections, a thorough cleaning and proper re-support often restores full function. But in Twin Oaks Valley Ranch specifically, we find original flex that’s torn at framing penetrations, crushed where straps failed, or disconnected entirely at couplings. When the duct itself is compromised, cleaning alone won’t fix airflow or safety, and we recommend replacement with rigid metal ducting. We’ll show you the camera footage and explain both options with exact pricing before you decide.
For San Marcos homes built in the 1990s-2000s tract boom, we recommend annual inspection and cleaning every 12-18 months. The combination of aging original flex duct, Santa Ana dust loading, and in some neighborhoods post-wildfire ash residue means these systems accumulate faster than the national average. Homes with multiple pets, heavy laundry volume, or long horizontal runs should lean toward the 12-month side. We note your last service date and send a reminder when you’re due - no pressure, just a prompt. Call (323) 918-4345 to schedule or ask about our recurring service tracking.
