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 HVAC Cleaning Across San Leandro
HVAC cleaning in San Leandro typically costs $350 – $650 for a complete system cleaning of a standard single-family home, and most jobs are finished in a single visit. That price covers the full system: supply and return ducts, the air handler, blower motor, evaporator coil, and a written guarantee on the work. At Cardinal Air Duct Cleaning, we give you that number in writing before a single duct is touched, and the price doesn’t change at the door. Call (737) 727-2314 and you’ll talk to a live person who can schedule you right then.
We know San Leandro’s housing stock because we work in it every week. From the 1940s bungalows near downtown to the 1960s ranchers climbing toward the hills, the combination of marine air from the bay and aging duct runs creates a specific kind of buildup. Our HVAC Cleaning team works with equipment built for real source removal, not a surface-level once-over.
Why Cardinal Air Duct Cleaning Is San Leandro’s Preferred HVAC Cleaning Company
Omar Haddad leads our team, and the standard he set is simple: show the homeowner what’s actually in their ducts, fix it, and photograph the result. No scripted sales pitch, no mystery pricing. That’s why San Leandro homeowners keep us on speed dial when the system starts pushing dust back into the living room.
Every technician who shows up at your door in San Leandro is background-checked, uniformed, and you’ll know their name before they arrive. We run Rotobrush agitation systems and Nikro HEPA vacuums on every job. When we work in older neighborhoods like Broadmoor or Estudillo Estates, where return ducts often pull in decades of settled grime, that equipment is the difference between moving dust around and actually removing it.
We’re part of the Relay Home Co. family, founded in 2005, and we operate under The Relay Visibility Guarantee. That means you get a live trackable arrival window, before-and-after photos of your own ducts, and a digital invoice you can pay from your phone. The 365-Day Done Right Promise backs every single job: if the work isn’t right within a full year, we come back and make it right at no charge.
Our dispatch is coordinated from the San Francisco Bay Area office, and our crews serve San Leandro directly. We answer the phone 24/7. No voicemail loops.
AC Vent Cleaning in San Leandro
AC vent cleaning in San Leandro is the most requested part of our HVAC cleaning service, and for good reason: those supply registers are where you see the problem. When the system runs in summer, every room with a register gets whatever the ducts send. In San Leandro, we see supply runs coated with a fine, gray, slightly sticky film from years of fog-born moisture carrying dust into the system. A full AC vent cleaning for a typical San Leandro home runs $175 – $300 as a standalone job, or it’s included in a complete system cleaning.
Source-Level Vent Removal
We don’t wipe register faces and call it done. The vent opening is the visible end of a run that goes back to the trunk line. We photograph inside the run, agitate the buildup loose, and pull it back to the vacuum at the source. You get the photos after.
When It’s Actually Needed
In San Leandro’s marine climate, the buildup on vent interiors happens slowly. Most homes need AC vent cleaning every three to five years, not annually. If you see dust puffing from registers when the system kicks on, or if the vent face needs wiping more than once a month, it’s time.
Furnace Duct Cleaning in San Leandro
Furnace duct cleaning in San Leandro matters most for homes built before 1980, which is a large share of our service area. Those older furnace systems often have return ducts in the floor or low on the wall, and in San Leandro’s damp winter months, those returns pull in moisture along with household dust, pet hair, and whatever the fog carries. A furnace duct cleaning for a typical San Leandro single-family home ranges from $350 – $650, depending on system size and the number of returns.
Return-Side Focus
Most of the crud in a furnace duct system lives on the return side. That’s the side pulling air into the system, so it catches everything. In older San Leandro homes, we regularly see return boots that haven’t been opened since the house was built.
Blower and Air Handler
A furnace duct cleaning that skips the blower and air handler is half a job. Dust that collects on the blower wheel throws off balance, shortens bearing life, and recirculates whatever it’s holding. We clean the blower, the heat exchanger surfaces, and the air handler interior as part of every furnace duct cleaning.
Trusted Brands We Service in San Leandro
We service and clean systems from every major manufacturer you’ll find in San Leandro homes: Carrier, Trane, Lennox, Rheem, Goodman, Bryant, and more. When filtration is part of the job, we stock Honeywell and Aprilaire media cabinets and replacement filters so there’s no second trip for parts. Our technicians also carry Abatement Technologies containment materials for jobs where a home has heavy contamination or a resident with respiratory sensitivities. You won’t wait on a parts order.
Common HVAC Cleaning Problems We See in San Leandro Homes
- Fog-borne sticky residue. San Leandro sits in a marine-influenced corner of the East Bay, and the salt-laden air pushed inland from the bay mixes with household dust to create gluey buildup that clings to duct walls instead of blowing clean. Inland cities don’t see this at the same rate.
- Half-sealed returns in older homes. The 1940s and 1950s housing stock in neighborhoods like Broadmoor and Davis Tract often has return air paths that were never sealed, so they pull dust from wall cavities and crawlspaces, not just living space.
- Oversized blowers with clogged wheels. When a furnace was replaced but the ducts weren’t, the blower often works harder than it should. Dirt on the wheel makes that worse. We see this constantly in post-2000 furnace replacements in original ductwork.
- DIY vent-cleaning debris. Homeowners run a vacuum hose or a brush as far as they can reach, then leave loosened debris deeper in the run. It recirculates when the system runs. We’ve pulled everything from dryer lint to building debris out of San Leandro ducts.

FAQs About HVAC Cleaning in San Leandro
Every three to five years for most San Leandro homes. The fog and salt buildup that makes our duct residue sticky accumulates slowly, not fast enough to justify annual service. If you have pets, live near a busy road, remodeled recently, or someone in the home has respiratory issues, lean toward the three-year mark. Call (737) 727-2314 and we’ll tell you honestly whether your system needs it now.
No. We charge one flat price per system. Per-vent pricing is how discount operators hide the real cost: the price looks low until you multiply it by 20 registers plus returns, then “discover” the trunk line and air handler are extra. With us, the price you agree to covers everything. Full stop.
We set up negative-pressure extraction at the air handler using a Nikro HEPA vacuum, which means loosened debris goes straight into the vacuum, never back into your living room. Then we run Rotobrush agitation tools through each supply and return run, clean the blower, evaporator coil, and air handler interior, and photograph the trunk line and key runs before and after. You see what we saw.
No, and no honest company should. HVAC cleaning is a scheduled job, and doing it right takes several hours. We book appointments with a live trackable arrival window, not an eight-hour “sometime Tuesday.” Call and we’ll find the soonest slot that works, usually within days.
Because a shop-vac in the driveway doesn’t do source removal. Rotobrush agitation breaks loose the sticky, fog-borne residue that clings to San Leandro duct walls, and Nikro’s HEPA-rated vacuum captures it at the air handler. The result is visible in your before-and-after photos. No generic equipment means no way to prove the work actually happened. We prove it, every time.
