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.
Fast, Reliable HVAC Cleaning Across San Leandro
HVAC cleaning in San Leandro typically runs $340-$680 for a full system, depending on home size and how much fouling has accumulated on the coils and blower. Most jobs are completed in one visit, and the work includes a documented photo record of every component before and after. If your registers are coated in dark film and your system runs constantly without cooling like it used to, the coil and blower are probably why. Call (806) 606-6902 for a written price before any work starts.
We work throughout San Leandro, from Washington Manor to Estudillo Estates to the Broadmoor neighborhood, and we know what the I-880 corridor does to residential HVAC equipment. That’s not a theory; it’s the diesel particulate film we photograph on evaporator coils in this city every week. Our HVAC Cleaning team documents what they find, shows you the photos, and only then does the work begin.
Why CleanRun Air Duct Cleaning Is San Leandro’s Preferred HVAC Cleaning Company
CleanRun has built its reputation in San Leandro on a practice most companies don’t offer: every component is photographed before and after, and the customer receives that photo record as a standard deliverable. When we open an air handler near Dutton Avenue and find a coil matted with diesel soot and salt-driven microbial growth, you see exactly what we see. No vague descriptions, no vague “it was dirty.” You get images of your own equipment.
We’re independently owned and operated under the Haven Standard, founded in 2013, with 52,000+ homes served. Every one of those homes received a written price before work started. That’s Haven Standard Clause 1, and it’s not negotiable. If a technician arrives at your San Leandro home and tells you the price changed after opening the panel, that’s not us.
Our background-checked, uniformed technicians operate under the H.A.V.E.N. Standard, with license number published on the page, not buried in a footer. Tomas Reyes leads the team, and he’s the same person who will put your written estimate next to any competitor’s quote you bring us. Free second opinion, in writing.

Our HVAC Cleaning Services in San Leandro

Evaporator Coil Cleaning
The evaporator coil is where the refrigerant absorbs heat from your home’s air, and in San Leandro, it’s also where diesel particulate from the I-880 corridor and salt-laden marine air deposit themselves. A fouled coil loses efficiency fast: the system runs longer cycles, consumes more power, and still can’t hold temperature on hot September days when the marine layer burns off by noon. We remove the coil access panel, photograph the fouling, and clean it with professional-grade equipment-not a spray-and-wipe that leaves the inner fins clogged. Typical evaporator coil cleaning in San Leandro runs $180-$320 when performed as part of a full system clean.

Blower Cleaning
Your blower motor and wheel move air across the coil and through the ductwork. When the blower wheel accumulates the fine diesel soot common in San Leandro neighborhoods within a half-mile of 880, it throws the wheel out of balance. You’ll hear a vibration or hum that wasn’t there two years ago, and airflow drops even though the motor still spins. We pull the blower assembly, photograph the wheel, clean each blade, and check the motor’s amp draw. Blower cleaning in a typical San Leandro home runs $140-$240.

Condenser Cleaning
The outdoor condenser coil rejects heat to the outside air, but in San Leandro, it also collects road film, salt, and airborne particulate from the constant container-truck traffic on 880. A condenser caked in grime drives up head pressure, shortens compressor life, and kills efficiency. Some homes along Washington Avenue or near Davis Street see condenser fouling in a single season that takes inland homes three years to accumulate. Condenser cleaning in San Leandro runs $120-$200, and it should happen annually given the local air conditions.

Air Handler Cleaning
The air handler cabinet houses the blower, coil, and often the filter rack. In San Leandro’s post-war tract homes, these cabinets are frequently located in garages or utility closets that share air with outdoor conditions. The cabinet interior collects dust, fiberglass particles from degrading duct liner, and moisture-driven microbial growth at the drainage pan. We clean the full cabinet interior, check the drain line, and photo-document everything. Air handler cleaning in San Leandro runs $160-$280.

Coil Treatment
Coil treatment is where we apply an EPA-registered antimicrobial treatment after mechanical cleaning. It’s not a substitute for cleaning; it’s the step after source removal. In San Leandro, where salt air accelerates microbial growth at coil fins and drain pans, this step matters more than in Hayward or San Lorenzo further from the bay’s direct influence. Coil treatment runs $80-$140 and is included in our full-system clean at no additional charge.

Common HVAC Cleaning Problems We See in San Leandro Homes

- Diesel soot film on registers and coils. Homes within a half-mile of I-880 accumulate the dark particulate film that Port of Oakland container traffic generates. It’s not household dust; it’s combustion particulate, and it coats coils fast. We photograph it on nearly every Washington Manor and Broadmoor job we take.
- Salt-driven microbial growth at duct joints. San Leandro’s persistent summer marine layer drives moisture into duct runs through leaky registers and attic run connections. That moisture feeds microbial colonization at the boot connections and coil drain pans-a problem more severe here than in Tri-Valley cities just 20 miles inland.
- Deteriorated fiberglass duct liner. The 1950s-70s tract homes in neighborhoods like Estudillo Estates and Washington Manor often retain original galvanized ductwork with early fiberglass liner. That liner breaks down over decades and sheds particulate into the air stream. HVAC cleaning can remove the loose particulate, but damaged liner may need replacement-we document it and give you a written scope for either path.
- Vibrating blower wheels. When diesel particulate coats a blower wheel unevenly, the imbalance creates the vibration or hum you hear through the return grille. Some San Leandro homeowners mistake this for a failing motor and get quoted a full replacement. Often the wheel just needs to be removed and cleaned. We show you the amp draw before and after.
Pricing for HVAC Cleaning in San Leandro, CA
A full HVAC cleaning for a 1,200-1,800 square foot San Leandro home runs $340-$680. That includes evaporator coil cleaning, blower cleaning, air handler cleaning, and condenser cleaning as applicable. The written price covers the whole system, not a teaser that changes after the technician opens a panel. No per-vent pricing, no bait-and-switch coupons. What affects your number: home size, number of return runs, accessibility of the air handler, and how much fouling has accumulated. The 1960s home in Washington Manor with original ductwork will land on the higher end. A 1990s condo near the BART station lands lower. Every estimate is written and delivered before any work starts. That’s the whole point of Haven Standard Clause 1.

FAQs - HVAC Cleaning in San Leandro

The soot returns because the source wasn’t fully removed. If a previous company cleaned the register covers but skipped the evaporator coil and blower wheel, the residual particulate redistributes through the system within weeks. Or if they didn’t address the fiberglass liner that has absorbed years of diesel particulate, that liner remains a reservoir. San Leandro homes within a half-mile of I-880 see this pattern repeatedly. A genuine clean removes the source contamination from the coil, blower, and accessible duct surfaces, then documents what was done. Call (806) 606-6902 and we’ll send you photos of what your system actually looks like inside.
HVAC cleaning removes the loose particulate that deteriorating liner sheds into the air stream, but it does not restore structural integrity to fiberglass liner that has broken down. If the liner is actively crumbling, we’ll document it with the camera, give you a written scope for liner repair or replacement, and clean what can be safely cleaned in the meantime. We won’t sell you a cleaning that pretends the liner isn’t failing. The photos tell the story.
Yes, because of the diesel particulate load from the I-880 corridor and the salt content in the marine-layer air. Hayward and San Lorenzo sit further from the constant Port of Oakland container-truck traffic pattern, and they don’t experience the same soot deposition rate on coils and blower wheels. San Leandro homes within a half-mile of 880 show coil fouling in two to three years that might take five or six years to accumulate in those neighboring cities.
A fogging product is a chemical mist applied through the duct system. It does not remove the diesel particulate or the salt-driven microbial food source on the coil fins. A real coil treatment starts with mechanical source removal, the physical cleaning of the coil and blower and accessible duct surfaces, then applies an EPA-registered antimicrobial treatment to the cleaned surfaces. In San Leandro, paying for a fog without the source removal leaves the problem untouched. The microbial growth comes back because the food source was never removed. Our coil treatment follows the cleaning, and the before-and-after photos show both steps.
Very likely. The black dust is diesel particulate, and the vibration suggests the blower wheel has accumulated enough of it to throw the wheel out of balance. We see this pattern regularly in Washington Manor and Broadmoor homes east of 880. The fix starts with pulling the blower assembly, cleaning the wheel blade by blade, and checking the motor’s amp draw against manufacturer spec. We’ll show you the amp numbers before and after. Call (806) 606-6902 for a written price.
What Makes San Leandro Different for HVAC Cleaning
San Leandro sits directly along the I-880 corridor, one of California’s highest-volume diesel freight routes connecting the Port of Oakland to distribution hubs south. That’s not a fact most HVAC companies think about. It means residential duct systems here accumulate diesel particulate matter at rates measurably higher than in comparable East Bay suburbs set back from the freeway. Combined with a dense stock of 1950s-70s post-war tract homes whose original forced-air ductwork has rarely if ever been serviced, San Leandro has an unusually large share of homes with both heavily soiled and structurally aging duct systems.
Our crew recently worked through a 1958 tract home in Washington Manor, just off Dutton Avenue, where the original galvanized supply and return ducts were coated in a dark, diesel-soot film and the evaporator coil was fouled with both particulate and salt-driven microbial growth. Using source removal with HEPA-filtered negative pressure and agitation tools, we restored airflow and knocked a persistent musty odor from the registers-a direct result of both the home’s proximity to 880 and our coil treatment process. That’s the kind of detail you’ll see in our photo record, not just hear about from a technician.
If your San Leandro home’s HVAC system hasn’t been cleaned in years, or if you’re seeing dark film on registers and hearing vibration from the blower, call (806) 606-6902 today for a written estimate. We’ll give you an exact dollar figure before any work starts, document everything with before-and-after photos, and stand behind it with the 365-Day Done Right Promise. This is what HVAC cleaning should look like.
