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 Marino
Air duct cleaning in San Marino typically runs $450-$850 for a full residential system, with most estate-sized homes falling in the $650-$800 range depending on total duct footage and accessibility. We’re usually scheduling within a few days, and our crews are familiar with the specific challenges of San Marino’s older homes. Call (323) 918-4345 for a free written estimate.
We’ve been working in San Marino long enough to know the difference between a 1926 Mediterranean on Woodstock Road and a 1948 Tudor Revival near Lacy Park. Our dispatch is coordinated from our Los Angeles office, but the crews serving San Marino live in the area and understand what they’re walking into: thick plaster walls, clay tile roofs, original sheet-metal trunks that haven’t seen daylight since the Hoover administration, and flex-duct additions that someone’s uncle installed in the 1980s. That local knowledge matters because it changes what equipment we load in the van and how long we block out for your job.
Why Morton’s Air Duct Cleaning Is San Marino’s Preferred Air Duct Cleaning Company
San Marino homeowners tend to find us through neighbors. Word travels fast on Huntington Drive when a crew leaves shoe covers on at the door, works quietly through a toddler’s nap, and emails a photo of the clean-up before driving away. Our reviews from San Marino customers consistently mention the written price we provide before any work starts, and the fact that we stick to it.
We don’t claim same-day dispatch because duct cleaning isn’t an emergency service, it’s a scheduled job that deserves preparation. What we do promise San Marino residents is a specific arrival window, background-checked uniformed technicians, and the Cedarwell Care Promise on every visit: shoe covers and drop cloths from the moment we enter, quiet tools during nap hours, pet-safe product choices where available, and that photo of the clean-up before we leave. The 365-Day Done Right Promise means if something isn’t right, we make it right. Full stop.
Paul Adeyemi leads our operations, and he’s particular about San Marino jobs because the homes demand it. A 4,000-square-foot estate with original 1930s ductwork and three later additions isn’t a standard clean. It requires two different cleaning approaches, careful camera inspection, and the patience to work around built-in bookcases, original millwork, and landscaping that’s older than most suburbs.
Air Duct Cleaning Services in San Marino
Air Duct Cleaning Services in San Marino cover the complete removal of accumulated debris from your supply and return ductwork, registers, grilles, and air handler components. For a typical San Marino estate home, you’re looking at $450-$650 for a straightforward single-system clean, $650-$850 for larger homes with multiple air handlers or extensive flex-duct additions, and $850-$1,200 for the most complex hybrid systems with pool houses, guest cottages, or significant accessibility challenges. Every estimate is written and agreed before we start.
Residential Duct Cleaning
Our residential work in San Marino focuses on protecting your home while we clean it. Floors get drop cloths. Furniture near registers gets moved with care, or worked around if it’s built-in. We use Rotobrush agitation systems on the original metal trunk lines where appropriate, and gentler Nikro source-removal equipment on flex-duct extensions that could tear under aggressive brushing. The goal is clean ducts, not damaged ducts.
Commercial Duct Cleaning
San Marino’s commercial properties, the office suites along Huntington Drive and the smaller professional buildings near Old Mill Road, need scheduled cleaning that doesn’t disrupt business hours. We work early mornings and weekends, provide the same written upfront pricing, and document the clean with before-and-after photos for property managers.

HVAC Duct Cleaning in San Marino
HVAC Duct Cleaning in San Marino addresses the full mechanical system, not just the visible registers. In this city’s estate homes, that often means discovering that your 1930s sheet-metal trunk lines, still hidden inside thick plaster walls, are joined to newer flex-duct extensions grafted on for added rooms or pool houses. One system, two completely different cleaning requirements. We price this honestly: a typical San Marino HVAC duct cleaning runs $550-$750 for a standard hybrid system, with complex multi-zone estates ranging $750-$1,100.
Full System Cleaning
Our full system cleaning includes supply ducts, return ducts, the air handler cabinet, blower assembly, and coil access where reachable. In San Marino’s older homes, we often find that the original metal trunks need aggressive agitation to break loose decades of compacted debris, while the newer flex sections need careful negative-pressure cleaning to avoid collapse or disconnection. We don’t treat them the same because they aren’t the same.
Video Inspection
We run camera inspection before and after major cleans, especially in San Marino homes where ductwork is embedded in plaster or routed through inaccessible attic spaces. You see what we see. On that 1938 Spanish Colonial Revival estate off Lorain Road, our tech ran a camera inspection down the original sheet-metal trunk and found it about 40% occluded with compacted smog-era debris, while the flex-duct extension serving the converted pool house was sagging and disconnected at a hidden takeoff. We set the system under negative pressure with HEPA filtration, used agitation tools on the metal trunk, reconnected and sealed the flex run with mastic and foil tape, and the static pressure at the air handler dropped measurably on the next visit.
Trusted Brands We Service in San Marino
We clean and service ductwork connected to all major HVAC brands, and we stock common replacement components locally for faster turnaround on San Marino jobs. Our equipment comes from Rotobrush, Nikro, and Abatement Technologies, not rental-grade machines. That matters in San Marino because original 1930s sheet-metal trunks need serious agitation torque that entry-level equipment can’t deliver, while delicate flex-duct extensions need precise vacuum control that cheap systems lack. When we recommend a Honeywell or Aprilaire filtration upgrade after cleaning, it’s because we’ve measured your system’s airflow and know what will actually fit and function in your specific duct configuration.
Common Air Duct Cleaning Problems We See in San Marino Homes
- Original metal trunks left untouched. Some crews only vacuum the easily-reached plenum and registers while the original plaster-embedded sheet-metal trunks in San Marino’s 1920s-1950s estate homes stay coated with decades of compacted debris. We camera-inspect and agitate-clean those hidden runs.
- Wrong method for mixed materials. Cleaning the metal trunk lines and flex extensions with the same method damages one or under-cleans the other. The older metal needs agitation tools; the newer flex sections need gentle source removal to avoid tearing. We adjust our approach per section.
- Disconnected runs from past renovations. Missing crushed or disconnected runs that were added during past renovations is common in San Marino homes expanded through multiple remodel cycles. Our camera inspection finds these before we quote, not after we’ve started.
- Wildfire smoke loading. The San Gabriel Valley’s bowl geography traps particulate matter at extreme concentrations, and Santa Ana events push ash directly into San Marino homes from fires burning in the Angeles National Forest. Ducts here load with fine PM2.5 faster than coastal communities, and standard filter changes don’t remove what’s already adhered to duct walls.
Pricing for Air Duct Cleaning in San Marino, CA
Here’s what honest pricing looks like for San Marino’s market. A typical residential air duct cleaning for a standard 2,000-3,000 square foot home runs $450-$650. The large estate homes that define San Marino, 3,000-5,000+ square feet with original 1930s-1950s ductwork and later additions, typically fall in the $650-$850 range. The most complex jobs, multi-system estates with pool houses, guest cottages, or significant accessibility issues due to plaster-embedded trunks, can reach $850-$1,200.
What moves you within these ranges: total linear footage of ductwork, number of air handlers, accessibility (crawl space vs. walkable attic vs. plaster-embedded), condition of existing ductwork (disconnected runs need reconnection, crushed sections need replacement), and whether you add dryer vent cleaning or filtration upgrades. We provide one flat price per system, agreed in writing before work starts. No per-vent pricing. No surprise add-ons once the van is in your driveway. Call (323) 918-4345 for your specific estimate.

FAQs About Air Duct Cleaning in San Marino
Both need attention, but for different reasons. The original sheet-metal trunk lines in San Marino’s 1930s-1940s homes are usually still structurally sound but heavily coated with compacted debris from decades before modern filtration existed. The newer flex runs often have gaps, sags, or disconnections that leak conditioned air and draw in attic or crawl space contaminants. We clean the metal with agitation tools and the flex with gentle negative-pressure source removal, then seal connections with mastic. Call (323) 918-4345 and we’ll camera-inspect both to show you exactly what you’re dealing with.
We run a video inspection camera through the system before quoting major work. In San Marino’s plaster-walled homes, you can’t see duct condition from the outside, and many flex-duct additions from past renovations were installed with minimal support, leading to sags or complete disconnections at takeoffs. The camera shows us the blockage, the gap, or the crushed section in real time. You’ll see it too.
Yes, our cleaning protocols align with NADCA ACR standards for source removal, negative pressure containment, and post-clean verification. In San Marino’s hybrid systems, that standard is especially important because it requires us to clean the entire duct system, not just the accessible portions, and to protect the home with containment during the process. Our HEPA-filtered collection and sealed access procedures meet or exceed those requirements.
A large San Marino estate clean typically takes a full day for a crew of two. We start with camera inspection of all trunk lines and major branches, then set up negative pressure containment with HEPA filtration. Original metal trunks get mechanical agitation with Rotobrush or equivalent tools; flex-duct extensions to pool houses or additions get gentle source removal with Nikro equipment. We reconnect any separated joints, seal with mastic and foil tape, and verify airflow improvement. Before we leave, you’ll get a photo of the clean-up and a written summary of what was found and corrected. Most estate jobs with pool house extensions fall in the $750-$1,100 range.
Every 4-6 years for most San Marino homes, and every 3-4 years if you’ve experienced significant wildfire smoke exposure or have family members with respiratory sensitivities. The combination of San Marino’s pollution-trapped air basin, dense tree canopy pollen load, and recurring wildfire smoke from the adjacent Angeles National Forest means ducts here accumulate fine particulates faster than in coastal or open-plain communities. After major smoke events like the 2020 Bobcat Fire, we recommended earlier inspection for homes directly downwind of the ridgeline. Call (323) 918-4345 to discuss your home’s specific exposure and schedule.
