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 Martin’s Preferred HVAC Cleaning Company
Most San Martin homes sit on larger lots than you’d find in Morgan Hill or Gilroy, which means longer return runs in unconditioned attics and more places for dust, rodent debris, and degraded flex duct to hide. Our HVAC Cleaning team has pulled some genuinely surprising things out of San Martin systems, from mouse nests in return plenums to flex duct that had collapsed and was pulling attic air straight into the house. Omar Haddad, who leads our crews, makes a point of walking homeowners through a camera inspection before any cleaning starts, so you see exactly what we see.
Homeowners looking for Air Duct Cleaning in San Martin regularly tell us two things. First, they appreciate that we quote one flat price per system, not per vent. Second, they like knowing the technician’s name before the van pulls up. Every Cardinal technician is background-checked, uniformed, and running professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies. Dispatch for San Martin is coordinated through our San Francisco Bay Area office, and crews serve the area locally with scheduling that fits typical South County workdays.
AC Vent Cleaning in San Martin
AC vent cleaning in San Martin means more than wiping register covers. It means removing the supply and return grilles, cleaning the interior of each vent boot, and clearing the first few feet of ductwork where dust collects against the register face. In San Martin’s older single-story homes, especially those along Monterey Road and the side streets off it, we regularly find the return vents are the dirtiest part of the system because they pull unfiltered air from hallways and living spaces into the air handler.
A full AC vent cleaning for a typical San Martin home runs $150 – $300 as part of a whole-system job. We don’t price per vent, because per-vent pricing hides the real cost and incentivizes skipping the runs that matter most.
What Our Crews Actually Do
We remove every register and grille, wash them, and inspect the boot with a camera before and after. If a boot is full of dust or pet hair, we clean it with hand tools and a HEPA-filtered vacuum, not by blowing it deeper into the duct. On San Martin homes with older stamped-steel registers, we check for rust and scored paint that can flake into the airstream.
When San Martin Homeowners Call Us
You’ll typically notice it first as dust accumulating on furniture within days of cleaning, or a musty smell when the AC kicks on. If you have pets or live on a dirt road near Llagas Road or Santa Teresa Boulevard, your vent boots fill faster than a suburban tract home. That’s not a defect. It’s the reality of San Martin’s rural air, and it’s easy to fix.
Furnace Duct Cleaning in San Martin
Furnace duct cleaning in San Martin targets the full supply and return runs that move heated air through your home from late fall through early spring. San Martin winters are mild by Midwest standards, but furnaces still run for a few hours every morning, and that’s enough to circulate dust, dander, and whatever’s accumulated in the ducts during the months the system sat idle. We clean the supply runs, the return runs, the plenums, and the air handler cabinet as one job.
Whole-system furnace duct cleaning for a San Martin home of 1,500 – 2,200 square feet typically runs $400 – $750 depending on the number of vents and the condition of the ductwork. We hand you a written quote before any work starts, and it does not change at the door.
Air Handler and Blower Cleaning
The blower motor and fan blades are the largest dust reservoirs in most San Martin systems, especially in homes built before 1990. We remove the blower assembly, clean the wheel and housing, and vacuum the cabinet with a HEPA-filtered unit. Skipping this step leaves the single biggest source of re-contamination in place, which is why we always include it.
Heat Exchanger Inspection During Cleaning
While we’re in the cabinet, we check the heat exchanger for cracks, rust, and soot buildup. We can’t repair a cracked exchanger, but we can flag it before it becomes a carbon monoxide risk. In older San Martin ranchettes, it’s one of the most common safety findings on systems that have run for 20-plus years without an inspection.
Trusted Brands We Service in San Martin
We service and clean systems from every major brand you’re likely to find in San Martin homes: Carrier, Trane, Lennox, Rheem, Goodman, York, and American Standard. We also carry replacement filters from Honeywell and Aprilaire for San Martin customers who want better filtration than a standard one-inch panel. Our use of Nikro HEPA vacuums and Abatement Technologies containment units means we can guarantee what we’re pulling out of your ducts stays out of your living space.
Common HVAC Cleaning Problems We See in San Martin Homes
- Rodent debris in return runs: San Martin’s mix of ranchettes and open land means mice and rats find their way into attic ductwork. We regularly remove nesting material, droppings, and chewed flex duct from return runs, then seal the entry points we can reach.
- Degraded flex duct in unconditioned attics: Long attic runs common on older San Martin properties sag, tear, and collapse over time. Collapsed flex duct chokes airflow and pulls unfiltered attic air into the home, which shows up as sudden dust or poor cooling in summer.
- Caked blower wheels on older systems: A blower wheel layered with dust runs out of balance and strains the motor. On 1970s-era single-story homes around San Martin, this is one of the most frequent findings on our camera inspections.
- Clogged evaporator coils from skipped filter changes: If the filter wasn’t changed regularly, the evaporator coil becomes a dust-and-hair mat that insulates the coil and drives up cooling costs. Coil cleaning is part of every whole-system job we do in San Martin.

FAQs About HVAC Cleaning in San Martin
Every 3 – 5 years for most San Martin homes, though ranchettes near open fields or dirt roads may need it more often because dust and rodent pressure are higher than in a typical suburban tract. If you have pets, kids, or anyone with allergies in the house, lean toward 3 years. If you just moved in and don’t know the system’s history, have it inspected once and you’ll know where you stand. Call (737) 727-2314 for an honest recommendation, even if the answer is “you don’t need it yet.”
One flat price per system, always. Per-vent pricing is how bait-and-switch operators hide the cost, because a San Martin ranchette with long attic return runs might have 18 vents and a deceptive per-vent quote can double by the time the tech is done. We quote a single number in writing before anything starts, and it covers every vent, every run, the plenums, and the air handler. Call us at (737) 727-2314 and you’ll get the real number up front.
We start with a camera inspection of the supply and return plenums so you see what’s actually inside. Then we seal off the system and run a negative-pressure HEPA vacuum at the air handler while we agitate the duct walls with rotary brushes. That means the dust we loosen goes straight into the vacuum, not back into your living room. We clean the blower, the evaporator coil, the plenums, and every vent boot. At the end, you get before-and-after photos of your own ducts. This is NADCA-standard source removal, not a register vacuum job.
Yes, often significantly, especially in San Martin homes where the ducts haven’t been touched in a decade or more. Removing the dust, pet dander, and pollen that cycles through your system every time the furnace or AC runs reduces the load on your family’s sinuses. The biggest improvement we see is when a homeowner upgrades to a MERV 13 filter after we clean the system. On a ranch property off Llagas Road, a homeowner’s MERV 13 filter stayed clean for months after our source removal plus new registers, where it had been clogging in weeks. That’s the difference between cleaning the system and actually fixing it.
No, and we’d be wary of anyone who promises it. A proper whole-system cleaning takes 3 – 5 hours and requires a camera inspection, containment setup, and methodical cleaning of every run. We schedule San Martin jobs on a real calendar, with a live trackable arrival window so you know exactly when we’re coming. No four-hour windows, no showing up late. Call (737) 727-2314 and we’ll get you on the schedule with a written quote in hand.
