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 El Granada’s Preferred Air Duct Cleaning Company
We’ve been part of the Cedarwell family since 2005, and our reputation in El Granada has been built one ranch home at a time. Homeowners here talk to each other, and word travels fast in a community this size. Our reviews from El Granada customers consistently mention the same things: the crew showed up in uniform, laid down drop cloths before touching anything, and the written price matched the final invoice exactly.
Response time to El Granada is typically next-day or within 48 hours, depending on season. We don’t pretend we’re around the corner when we’re not, but we do keep routes efficient so Coastside customers aren’t waiting weeks. Our technicians know to bring extra corrosion-rated inspection tools for this area, and they understand that a system that “barely runs” can be the one that needs the most attention.
Every visit is backed by our 365-Day Done Right Promise and the Cedarwell Care Promise. That means shoe covers and drop cloths on every visit, a written price before any work starts, and a photo of the clean-up before the crew leaves. A live person answers our phone 24/7, not a voicemail tree.
Commercial Air Duct Cleaning in El Granada
Commercial Air Duct Cleaning in El Granada covers restaurants near Highway 1, small professional offices, and retail spaces where coastal humidity creates the same accelerated conditions seen in residential systems but with higher occupancy and code considerations. A typical commercial duct cleaning in El Granada runs $800-$2,400 depending on system size, access difficulty, and whether kitchen exhaust is included. We use Rotobrush and Nikro commercial-grade equipment with HEPA containment, and every job starts with a written scope and price.
Kitchen Exhaust and Grease Systems
Coastal moisture in El Granada mixes with grease particulate to form a particularly stubborn residue in kitchen exhaust ducts. We clean the full hood-to-fan path using Abatement Technologies containment systems, with before-and-after photos for your records.
Office and Retail HVAC Maintenance
Small commercial buildings in El Granada often share the same 1950s-1970s construction era as the homes. We inspect mixed-use systems for corrosion at metal joints and verify that salt-air degradation hasn’t compromised duct integrity before cleaning begins.
Air Duct Cleaning Services in El Granada
Air Duct Cleaning Services in El Granada address a specific coastal problem: Pacific marine fog maintains near-constant high humidity that infiltrates ductwork and creates mold, mildew, and corrosion conditions fundamentally different from what we see even 10-15 miles inland. A typical whole-home residential cleaning in El Granada runs $350-$650, with video inspection and source removal under negative pressure as standard. We don’t quote per-vent prices because that’s how bait-and-switch starts. One flat price per system, agreed before work starts, every time.
Video Inspection Before Cleaning
We run a camera through your supply and return lines before touching anything. In El Granada, we’re often documenting corrosion scale and biological growth that surprises homeowners whose systems “barely run.” The video becomes part of your record and helps us target the cleaning plan.

Source Removal with HEPA Containment
Our crews use Rotobrush agitation tools and Nikro negative-pressure collection systems with HEPA filtration. Agitation matters here. Salt-accelerated corrosion scale and biofilm bond stubbornly to old sheet-metal joints in these 1950s-1970s homes. Vacuum-only cleaning leaves it behind.

Trusted Brands We Service in El Granada
We clean and maintain systems using equipment and components from Rotobrush, Nikro, Honeywell, Aprilaire, and Guardsman. For El Granada customers, this means we can source replacement parts for most residential and light commercial systems without the long lead times that coastal residents sometimes face. Our technicians arrive with the right agitation heads, HEPA filters, and corrosion-rated inspection cameras already on the van. Fast turnaround matters when your ducts are holding moisture that isn’t going away on its own.
Common Air Duct Cleaning Problems We See in El Granada Homes
- Biological growth in lightly-used systems. Because El Granada’s marine climate keeps humidity high and temperatures mild, the lightly-used heating systems in its 1950s-1970s ranch homes can carry worse mold and biological growth than heavily-run systems 10-15 miles inland in Redwood City. Infrequent airflow never purges the coastal moisture that settles in the ducts.
- Salt-accelerated corrosion of metal duct joints. The salt content in El Granada’s coastal air corrodes metal fasteners and joint connections faster than inland environments. We regularly find compromised seals in original sheet-metal trunk lines that have been slowly degrading for decades.
- Filter overload from persistent dampness. High marine humidity consumes filter capacity faster than dry climates. A MERV rating that works fine in San Mateo can strain a blower motor in El Granada when the filter is saturated with moisture-borne particulate.
- Outbuilding and detached structure neglect. Rural properties around El Granada often have shop or studio spaces with separate duct systems that sit stagnant for months. These systems face the same coastal moisture without any periodic airflow to mitigate it.
Pricing for Air Duct Cleaning in El Granada, CA
Whole-home residential air duct cleaning in El Granada typically runs $350-$650 for a standard single-story ranch system. Two-story homes or those with separate zone systems range $550-$950. Commercial systems start around $800 and scale with square footage and access complexity. Video inspection adds $75-$125 if done as a standalone service, but it’s included when you book a full cleaning.
What moves the price: system size, number of main trunk lines, access difficulty (crawl space vs. attic), and whether we find corrosion damage that needs repair referral. We do not charge per vent. One flat price per system, written and confirmed before work starts. No surprises on the invoice.

FAQs About Air Duct Cleaning in El Granada
Every 3-5 years for most El Granada homes, but coastal ranch properties with infrequently-used systems should consider inspection every 2-3 years. The marine moisture here creates conditions that inland homes simply don’t face. Call (323) 918-4345 to discuss your specific system and we’ll recommend an interval that makes sense for your home.
Yes, and this is exactly the scenario we see cause the most problems in El Granada. Stagnant, moisture-laden air in ducts off Capistrano Road can breed mold that heavier inland use would never allow. We took a call on a 1960s single-story ranch off Capistrano Road where the homeowners only ran the furnace a handful of times each winter, yet every time it kicked on the house smelled like a damp basement. Our tech ran a camera inspection and found heavy biological growth and surface corrosion on the original sheet-metal supply and return ducts, worse than many systems we see that run daily - after sealing the trunk and setting up source removal under negative pressure with HEPA filtration, the odor was gone.
Yes. The salt content in coastal air accelerates corrosion of metal duct joints and fasteners, and the persistent humidity keeps that corrosion active year-round. We find surface pitting and joint separation in El Granada systems that inland technicians rarely encounter. This is why we bring corrosion-rated inspection cameras and why we check metal integrity before recommending any cleaning approach.
Proper cleaning means video inspection first, then source removal under negative pressure with HEPA filtration using agitation tools like Rotobrush systems - not just a vacuum hose waved at a vent. In El Granada, we also verify that salt-air corrosion hasn’t compromised duct integrity and that biological growth is fully addressed, not just disturbed. Every job ends with a photo of the clean-up before the crew leaves.
Yes, if they have their own duct systems. Rural properties around El Granada often have shop, studio, or guest house systems that face the same coastal moisture without any periodic airflow to mitigate it. These systems frequently show worse contamination than the main house because they’re completely ignored. We price detached structures as separate systems with the same flat-price, upfront standard.
