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 San Marcos
Air duct cleaning in San Marcos typically runs $350-$650 for a full residential system, and most jobs are scheduled within a few days of your call. Our crews live and work in North County, so we know the difference between a coastal Carlsbad home and a San Marcos inland-valley tract house, and we bring the right equipment for what your ducts actually contain.
We’re Morton’s Air Duct Cleaning, part of the Cedarwell family, and we’ve been sending crews to San Marcos since 2005. Scheduling runs through our San Diego office, but the technicians who arrive at your door in San Elijo Hills, Twin Oaks Valley, or Rancho Coronado are local North County pros who understand Santa Ana wind loading, 1990s flex-duct aging patterns, and the construction dust issues that plague newer builds here. Call us at (323) 918-4345 for a free written estimate before any work starts.
Why Morton’s Air Duct Cleaning Is San Marcos’s Preferred Air Duct Cleaning Company
San Marcos families call us back because we treat their homes like our own. Our technicians wear shoe covers and lay drop cloths before stepping past the entryway, work quietly when there’s a toddler napping down the hall, and choose pet-safe products wherever available. Every visit follows the Cedarwell C.A.R.E. values, and every job carries our 365-Day Done Right Promise.
Paul Adeyemi leads our operation with a simple rule: the written price you approve is the price on the invoice. No per-vent add-ons, no “discovered problems” once the van is in your driveway. We use professional-grade Rotobrush and Nikro equipment, not rental-shop vacuums, and we leave a photo of the clean-up before we go so you can see the difference.
A live person answers our phones 24/7. Not a chatbot, not a callback queue. Real scheduling, real answers, real crews in uniform who’ve passed background checks.
Commercial Air Duct Cleaning in San Marcos
Commercial Air Duct Cleaning in San Marcos covers offices, retail spaces, medical suites, and multi-tenant buildings where code compliance and indoor air quality standards matter more than in a single-family home. We build a containment plan around your business hours, set up HEPA-filtered negative pressure to protect occupied areas, and document every stage for property managers and inspectors. A typical commercial system in San Marcos runs $800-$2,400 depending on square footage, access difficulty, and whether video inspection is required for compliance records.
Scheduled Around Your Operations
We clean after hours and on weekends so your San Marcos business doesn’t lose productive time. Our crews work with property managers at retail centers along Rancho Santa Fe Road and medical plazas near Twin Oaks Valley Road to minimize tenant disruption.
Code Documentation and Video Records
Many San Marcos commercial leases now require annual duct inspection documentation. We provide before-and-after video from our Nikro inspection cameras, timestamped and archived, so you have proof of compliance if the fire marshal or insurer asks.
Air Duct Cleaning Services in San Marcos
Air Duct Cleaning Services in San Marcos address a specific set of local conditions that coastal North County homeowners rarely face. The city’s inland valley position channels Santa Ana winds directly into HVAC intakes, loading ducts with fine Mojave desert dust and chaparral particulate that 1990s-2000s tract home flex ductwork was never designed to filter. Add construction debris from San Marcos’s ongoing building boom, and you get supply registers that puff visible dust every time the AC cycles on. A typical full residential cleaning in San Marcos runs $350-$650; video inspection adds $150-$250 if you want to see inside the trunk lines.
Source Removal, Not Surface Vacuuming
We use Rotobrush contact agitation and Nikro HEPA vacuum systems to dislodge debris from duct walls and remove it completely. Vacuum-only cleaning leaves packed dust against flex duct walls, especially in new San Marcos builds where construction debris has had months to settle and harden.
System Inspection and Repair Coordination
Our camera inspection finds the torn flex liners and loose trunk connections that develop after 20-30 years in San Marcos’s temperature swings. When we find damage, we explain it clearly, quote the repair separately, and never proceed without your written approval.

Trusted Brands We Service in San Marcos
We clean and maintain systems built around Aprilaire, Abatement Technologies, Guardsman, and Rotobrush equipment, and we stock common fittings and filter sizes for San Marcos’s most prevalent HVAC configurations. The 1990s-2000s tract homes in San Elijo Hills and Rancho Coronado typically run Honeywell or Aprilaire media filters; we carry those sizes on every truck so there’s no delay if your filter housing needs attention during the cleaning. Our Nikro HEPA collectors and Rotobrush agitation systems are professional-grade, not rental-grade, because San Marcos’s dust loading demands real extraction power.
Common Air Duct Cleaning Problems We See in San Marcos Homes
- Construction dust packed in new builds. Contractors in San Marcos’s booming development zones often run air handlers during final construction without sealing registers, pulling sawdust and drywall particulate directly into the blower motor and coating the air handler cabinet. We find this in nearly every handover inspection in San Elijo Hills and Rancho Coronado.
- Santa Ana wind debris in return plenums. The inland valley funnels hot, dry, 30-60 mph offshore winds directly into HVAC intakes, loading return-air plenums with that distinctive ochre-tan Mojave dust mixed with charred chaparral debris. Coastal cities 10 miles west don’t see this signature.
- Torn flex duct liners in aging tract homes. San Marcos’s dominant housing stock of 1990s-2000s master-planned communities is now 20-30 years old, the age range where original flex duct connections loosen and inner liners tear, dumping insulation into supply runs and creating the metallic rattles we get called about regularly.
- Wildfire ash residue from interface fires. Neighborhoods like Twin Oaks Valley sit in the wildland-urban interface, and duct systems here accumulated ash and smoke residue during the 2017 Lilac Fire that standard filters never captured. We still find this layer in older return plenums.
Pricing for Air Duct Cleaning in San Marcos, CA
Most full residential air duct cleaning jobs in San Marcos fall between $350 and $650 for a complete supply-and-return system clean with agitation and HEPA extraction. Video inspection runs $150-$250 additional. Commercial systems start around $800 and scale with square footage and access complexity.
What moves you within that range: the number of supply and return registers, whether your system uses hard duct or flex duct (flex takes longer to clean properly), accessibility of the air handler, and whether we find damage that needs repair coordination. We give you one flat price per system, agreed in writing before any work starts. No per-vent pricing, no teaser coupon that balloons on arrival.

FAQs About Air Duct Cleaning in San Marcos
Yes, and probably sooner than you expect. Builders in San Marcos often run the air handler during final construction without sealing registers, pulling sawdust and drywall particulate directly into the blower motor and coating the air handler cabinet. We see this in nearly every handover inspection in San Elijo Hills and Rancho Coronado. That debris doesn’t stay put; it re-enters your supply air the first hot week of summer when your AC runs hard. Call (323) 918-4345 for a free estimate - we’ll show you what’s actually in there.
San Marcos’s inland valley channels Santa Ana winds directly into your HVAC intake, loading ducts with fine Mojave desert dust and charred chaparral debris that standard filters can’t stop. In San Elijo Hills and the Twin Oaks corridor, we routinely pull that distinctive ochre-tan dust mixed with charred bits from return-air plenums even in homes with windows sealed tight. The dust isn’t coming from outside your house; it’s coming through your ducts. A professional cleaning with HEPA extraction and contact agitation removes the reservoir.
Every 3-5 years for most San Marcos tract homes, but sooner if you have pets, recent construction, or visible dust from registers. The original flex ductwork in 1990s-2000s builds like Rancho Coronado and Twin Oaks Valley Ranch is now 20-30 years old, the age where connections loosen and liners tear, accelerating dust accumulation and potentially distributing insulation particles into your air. We include video inspection so you can see whether your specific system needs cleaning or repair.
No, and vacuum-only cleaning is exactly what leaves San Marcos homeowners disappointed. Our process uses Rotobrush contact agitation to dislodge debris from duct walls, then Nikro HEPA vacuum systems to remove it completely under negative pressure. We protect your floors with drop cloths, seal registers during the process, and run a final camera verification so you see the result. The photo of your clean-up is in your inbox before our crew leaves.
Yes, and in San Marcos’s wildland-urban interface neighborhoods like Twin Oaks Valley, it already has. Standard HVAC filters don’t capture the fine ash and smoke particulate from wildfire events; it passes through, settles in return plenums and trunk lines, and becomes part of your system’s dust reservoir. We still find Lilac Fire residue in older San Marcos homes. If you smell smoke when your AC first kicks on, or if your filters load unusually fast, that’s likely the cause. Call (323) 918-4345 and we’ll inspect.
