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 Cardinal Air Duct Cleaning Is San Leandro’s Preferred Air Duct Cleaning Company
San Leandro homeowners keep calling us for a simple reason: we tell them what the job will cost before the van even arrives. That’s rare in this trade. A lot of companies around the East Bay still quote “per vent,” which on a 1950s bungalow with a dozen small registers becomes a number that has nothing to do with the actual work. We quote one flat price per system and hand it to you in writing. If the number looks higher than you expected, you can tell us to stop right there. No one is on your property yet. No awkwardness.
Our technicians arrive in uniform, background-checked, and carrying professional-grade equipment: Rotobrush whip lines for branch agitation, Nikro HEPA vacuums for true negative-pressure extraction, and Abatement Technologies containment when a crawlspace or attic has contamination that should not migrate into living space. You’ll know your tech’s name before they knock. And because we’re part of the Relay Home Co. family, founded 2005, every booking carries the Relay Standard: a live trackable arrival window, before-and-after photo documentation, and a digital invoice payable from a link on your phone. That’s it. No four-hour windows, no mystery pricing, no phone tag.
Omar Haddad leads the team here, and the standing rule is this: if the work isn’t right within 365 days, we come back and make it right. That’s the 365-Day Done Right Promise, and it covers every job without exception. Not just select ones.
Ductwork Cleaning in San Leandro
Ductwork cleaning in San Leandro means removing the accumulated dust, pet dander, construction debris, and sometimes worse from inside your supply and return ducts, branch runs, and the main trunk line. The job differs house to house because San Leandro’s housing stock splits sharply along the 880 corridor. Pre-war bungalows and 1950s tract homes near downtown, Broadmoor, and the East 14th corridor often still run original galvanized steel or early flex duct. Meanwhile, homes in the Marina and Bay-O-Vista hillsides have crawlspace and attic runs that pull in salt air and marine moisture year-round. A camera inspection here routinely finds two completely different problems on the same block.
The process itself is source removal: we set up a HEPA-rated negative-pressure vacuum at the main trunk so that any debris we loosen gets pulled directly out, not blown into your living room. Then we agitate the duct walls with rotary brushes and compressed air whips to break up the packed layer. The price for a standard single-system ductwork cleaning in San Leandro runs $425 – $650 for homes with accessible duct runs and no prior documented cleaning. Larger homes with two systems or older galvanized trunk lines packed with decades of material run $650 – $890.
Source Removal Method
Trade term: negative-pressure extraction. That means the loosened debris goes straight into the vacuum, not back into your home. Cheap outfits skip this and just blast compressed air around a disconnected blower motor. The dust settles back into your duct runs within weeks. We pull it out at the source, and we show you the photo proof.
Older Galvanized Systems
If your San Leandro home was built before 1965 and has never had the ducts opened, the galvanized trunk may hold 60-plus years of material. A quick vacuum won’t do it. We use mechanical agitation to break up that compacted layer, then extract it under negative pressure. This is exactly the kind of job where per-vent pricing falls apart. One flat price per system, agreed before we start.
Air Duct Inspection in San Leandro
Air duct inspection in San Leandro is the step that separates a real diagnosis from a guess. We push a camera down your supply and return runs and look at what is actually in there. You see the images. We point to the dust buildup, any crushed flex, disconnected joints, or microbial growth, and we tell you honestly whether cleaning will solve your problem or whether something else is going on. The inspection is included with every full duct cleaning; as a standalone service it runs $149 – $249 depending on how many runs and access points are involved.
A homeowner on Estudillo Avenue near downtown called us about a bedroom that never cooled and a musty smell only in summer. Our tech pulled the air handler in the hall closet, ran the camera down the supply and return ducts, and found the original 1950s galvanized trunk packed with dust and a crushed flex branch feeding that bedroom. That’s inspection doing its job: finding the real problem before anyone touches a brush. We set up negative pressure with HEPA filtration at the main trunk, used agitation tools and a Rotobrush whip through the branches, sealed the crushed run, and handed the homeowner before-and-after photographs of their own ducts along with the flat per-system price we had agreed before we started.
Camera Documentation
Every inspection includes still images. You see what we see, plainly labeled. If we find something beyond cleaning, like a failed joint or a crushed run, we document it and quote a repair separately. No pressure.
Marine Air and Crawlspace Runs
In Bay-O-Vista and the Marina district, crawlspace and attic flex duct absorbs marine moisture year-round. That environment quietly supports microbial growth in the duct insulation that a quick vacuum never addresses. A camera inspection catches it before you’re breathing it. In downtown and Broadmoor, inspections more often turn up decades of packed dust and crushed branches. Two different problems, same two-mile radius.
Trusted Brands We Service in San Leandro
We work with the equipment already installed in San Leandro homes. That includes systems built around Honeywell filtration, Aprilaire media cabinets, and Guardsman UV products. We stock common filters and replacement components for local customers so a follow-up isn’t a two-week wait. When a cleaning reveals a filtration product that belongs in your system, we’ll recommend it, show you the price, and install it the same visit if you approve. No upsell theater. Just a straight recommendation with a number attached.
Common Air Duct Cleaning Problems We See in San Leandro Homes
- Original galvanized trunk lines packed with decades of material. Homes near downtown and Broadmoor, built in the 1940s and 1950s, often have never had the main trunk opened. The layer of compacted dust can be 2 – 3 inches thick. This requires mechanical agitation and proper HEPA extraction, not a quick vacuum pass.
- Crushed or disconnected flex branches. In older homes, flex runs added during remodels get pinched between joists or pulled loose at the collar. One crushed branch means one room that never cools while the rest of the house is fine. The camera inspection finds it; the cleaning crew fixes it.
- Salt-air moisture in crawlspace and attic flex. Marina and Bay-O-Vista homes sit close enough to the San Francisco Bay that marine air moves through crawlspaces constantly. Flex duct insulation stays damp. That supports microbial growth no surface vacuum will remove. This is a real concern specific to San Leandro’s geography, not a generic scare line.
- Blow-and-go residue from previous cleanings. We regularly find homes where a previous company blasted compressed air through the registers without a collection vacuum. The dust was loosened, not removed. It resettled inside the duct runs and blew into the living space for weeks. We fix that with proper source removal.
Pricing for Air Duct Cleaning in San Leandro, CA
We never quote per vent. San Leandro’s older homes often have a dozen or more registers, and per-vent pricing is how a bungalow gets priced higher than the actual labor justifies. Instead, we quote one flat price per system, in writing, before any work begins. A standard single-system air duct cleaning in San Leandro runs $425 – $650. Homes with two systems or heavily packed original galvanized trunks run $650 – $890. A standalone camera inspection runs $149 – $249, and that fee is credited toward the cleaning if you book within 30 days. The price you sign is the price you pay. No dispatch fee, no fuel surcharge, no last-minute add-ons. Call (737) 727-2314 for a free estimate, and we’ll give you a number over the phone based on your home’s size, system count, and build era.

FAQs About Air Duct Cleaning in San Leandro
Per system. One flat price, in writing, before any work starts. We don’t do per-vent pricing because it unfairly penalizes San Leandro’s older homes, which often have a dozen or more small registers. The flat per-system price covers every supply and return register on that system, the main trunk, and all accessible branch runs. Call (737) 727-2314 for an exact quote. Estimates are free.
Every 4 – 7 years for most homes. If you have pets that shed, recent construction or remodeling on the property, or you live near the Marina or Bay-O-Vista where marine air keeps flex duct damp, every 3 – 5 years is more realistic. If your home has original 1950s galvanized ductwork that has never been opened, do it once now, document it, and then reassess in 4 – 5 years based on what the camera shows. We’ll tell you honestly if you don’t need it yet. Call (737) 727-2314 to talk through your situation.
Yes. Every job includes photo documentation of the interior of your ducts, before and after. You receive those images as part of the Relay Standard booking. That’s how you know the work was actually done, not just claimed on an invoice. If a photo ever shows something we missed, the 365-Day Done Right Promise applies. Call (737) 727-2314 to book.
Usually not, and we won’t pretend otherwise. Air duct cleaning is a scheduled job that takes several hours and involves professional equipment setup. We book real appointment windows through the Relay Standard, so you get a live trackable arrival time rather than a vague “sometime between 8 and 4.” When there’s a cancellation or an open slot, we do offer same-week service often. Call (737) 727-2314 and we’ll find the fastest real opening.
That depends on what the camera shows. If the trunk line is packed with 60 years of dust and debris, cleaning it properly removes a real source of airborne particulate and improves airflow. But if the galvanized runs are rusted through or collapsing, cleaning won’t fix them. That’s why we inspect before we clean. You see the condition, you see the cost, you decide. The inspection is credited toward the cleaning if you proceed. Call (737) 727-2314 for a straight conversation about your system.
