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 Martinez’s Preferred Air Duct Cleaning Company
We’ve been part of the Cedarwell family since 2005, and our reputation in Martinez has grown through one household at a time. Homeowners here talk to each other, and word travels fast when a crew leaves shoe covers on, works quietly past a napping toddler, or shows the actual photo of a clean return plenum before packing up.
Our response time to Martinez is typically next-day or within 48 hours, not because we rush, but because we keep crews stationed close enough to treat this city as local, not a dispatch afterthought. We know which homes near the Carquinez Strait need extra attention to trunk lines, and which downtown Victorians have duct runs that don’t match any standard diagram. That local knowledge means fewer surprises for you, and fewer callbacks for us.
Every visit carries the Cedarwell Care Promise: background-checked, uniformed technicians, drop cloths and shoe covers from the moment we enter, and a 365-Day Done Right Promise stamped on every invoice. If something isn’t right, we make it right. Full stop.
Vent Cleaning in Martinez
Vent Cleaning in Martinez means more than brushing off register covers. The supply and return vents in your home are the visible endpoints of a system that, in this city, is working harder than most. Between the refinery particulates that drift across the western and northern neighborhoods and the Delta winds that force outdoor air through every seam, Martinez vents collect a stubborn load that surface cleaning won’t touch.
Our Air Duct Cleaning team uses Rotobrush agitation tools and HEPA-filtered negative air machines to pull debris back through the vent openings into containment, not push it deeper into your ducts. A typical vent cleaning as part of a whole-system service in Martinez runs $120-$220 when done as a standalone, or it’s included in our full-system pricing. We check every boot and collar for gaps where the Delta wind is re-loading your system after we leave.
Supply Vent Cleaning
Supply vents push conditioned air into your rooms, and in Martinez they’re often the first place that dark, oily residue shows up. We remove each register, clean the boot and the first few feet of duct behind it, and seal any gaps in the wall or floor penetration that are pulling in unfiltered garage or crawl-space air.
Return Vent Cleaning
Return vents draw air back to your HVAC unit, which means they’re the collection point for everything airborne in your home. In Martinez homes near the refinery plume path, these vents and their filter housings need particular attention. We clean the grille, the filter track, and the plenum connection, and we note whether your filter is rated for the particulate load this city generates.
Air Duct Repair in Martinez
Air Duct Repair in Martinez addresses the gaps, collapses, and deteriorated seals that the Carquinez Delta winds exploit mercilessly. When your ductwork is under negative pressure from a running furnace or air handler, any opening pulls in attic dust, crawl-space moisture, and in this city, that distinctive refinery particulate blend. The result is rooms that never heat or cool evenly, systems that run longer, and duct interiors that soil faster even after cleaning.
Common repairs in Martinez include resealing trunk-line seams with mastic, replacing crushed flex duct in crawl spaces, and rebuilding plenum connections on retrofitted systems in older homes. A typical repair visit in Martinez runs $200-$450 for minor sealing and patching, or $500-$1,200 if we’re replacing significant flex duct or rebuilding a plenum. We always inspect with a camera first, show you what we found, and give you a written price before we cut or seal anything.
Sealing and Reconnection
Older Martinez homes, especially the Craftsman and Victorian retrofits downtown, often have duct sections that were joined with tape that’s now brittle, or flex duct that’s pulled off its collar. We resecure with mechanical fasteners and proper mastic, not duct tape, and we test for leakage before we call it done.
Crawl-Space Duct Replacement
Uninsulated sheet-metal or degraded flex duct in Martinez crawl spaces suffers from both the marine moisture and the particulate infiltration. When the duct is too compromised to clean effectively, we replace with properly insulated flex or hard pipe, supported correctly so it doesn’t sag and pool condensation.
Trusted Brands We Service in Martinez
Our trucks carry professional-grade equipment from Rotobrush, Nikro, Aprilaire, and Abatement Technologies, not rental-shop vacuums with brush attachments. For Martinez homes, that means HEPA-filtered negative air machines that can handle the heavy debris load this city’s ducts collect, and camera systems that let us show you the inside of your trunk lines in real time. We stock common fittings and flex duct sizes for faster turnaround on repairs, and our technicians are trained on the specific application of each tool, not just how to turn it on. When we mention Guardsman products for register and vent protection during the job, it’s because we’ve found they hold up to the residue profile we see here.
Common Air Duct Cleaning Problems We See in Martinez Homes
- Refinery particulate infiltration. Homes on the western and northern sides of Martinez, closest to the PBF Energy refinery plume path, routinely develop a dark, tacky film inside return plenums and trunk lines. It’s chemically distinct from ordinary household dust, and it requires agitation plus negative-air extraction to remove, not just vacuuming.
- Marine moisture and mold in crawl-space ducts. The Carquinez Strait funnels moist Delta breezes into Martinez year-round. Uninsulated sheet-metal trunk runs in older home crawl spaces stay cool enough to condense that moisture, creating the mold speckling we find on camera inspections regularly.
- Non-standard duct runs in historic home retrofits. The early-1900s bungalows and Victorians near downtown Martinez were never built for forced air. Decades-later HVAC retrofits often produced improvised duct paths through floor cavities and tight crawl spaces that are difficult to access and prone to debris accumulation where no standard tool reaches.
- Re-contamination from wind-driven infiltration. Even after thorough cleaning, Martinez ducts re-load faster than inland Contra Costa systems because the persistent Delta pressure differential forces outdoor air through gaps in duct seams, filter housings, and building envelopes that calmer climates don’t stress as hard.
Pricing for Air Duct Cleaning in Martinez, CA
Whole-home residential air duct cleaning in Martinez typically runs $350-$650 for a standard single-system home with 10-15 vents. Larger homes, dual-zone systems, or properties with significant contamination from refinery particulate and mold may run $700-$950. Commercial duct cleaning in Martinez starts around $800 and scales with system complexity. Dryer vent cleaning, which we often pair with duct work, runs $120-$180 as a standalone.
What moves the price: the number of supply and return vents, whether your system includes a main trunk line and multiple branches or a simpler radial layout, accessibility of crawl-space or attic runs, and the level of contamination we find on initial inspection. We do not quote per-vent pricing, and we do not bait with a low teaser rate that balloons once we’re in your home. One flat price per system, agreed in writing before work starts, every time. Call (323) 918-4345 for your specific estimate.

FAQs About Air Duct Cleaning in Martinez
Martinez sits adjacent to the PBF Energy refinery on the Carquinez Strait, and the prevailing winds carry petroleum-based particulates, sulfur compounds, and VOCs into residential HVAC systems. Combined with the Delta wind pressure that forces outdoor air through duct seams year-round, this creates a dark, tacky residue inside plenums and trunk lines that inland Contra Costa cities simply don’t see. Call (323) 918-4345 if you’re noticing dark buildup around your registers.
Yes. The Carquinez Strait acts as a natural wind tunnel, pushing marine Delta breezes through Martinez every afternoon from spring through fall. This persistent pressure differential drives far more outdoor air infiltration into duct systems than occurs in calmer inland cities, accelerating particulate loading and moisture-related microbial growth. Homes here benefit from more frequent inspection and, when indicated, more thorough cleaning. We’re happy to assess your system.
No. A fogging mist does not remove the petroleum-based film or the mold on uninsulated crawl-space runs that we find in Martinez homes. It only deposits a chemical layer on top of existing contamination. Source removal, agitation, and HEPA-filtered extraction are what actually clean your ducts. If a contractor’s headline service is fogging rather than mechanical cleaning, you’re paying for disguise, not results. We do not upsell fogging.
Expect non-standard duct runs that don’t match any textbook diagram. These systems were improvised decades after construction, often with flex duct or sheet metal routed through floor cavities and tight crawl spaces. We camera-inspect before we quote, identify access points and potential trouble spots, and give you a written price that accounts for the extra time and care these homes require. The 1920s bungalow off Ferry Street we mentioned earlier is representative of what we handle regularly.
We provide before-and-after camera inspection footage of your trunk lines and main plenums, and we show it to you before we pack up. If the dark film or mold speckling was there before, you’ll see it gone after, or we’ll keep working until it is. Every job ends with a photo of the clean-up, and every invoice carries our 365-Day Done Right Promise. Call (323) 918-4345 to schedule an inspection and see the standard for yourself.
