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 Air Duct Cleaning Across San Leandro
Air duct cleaning in San Leandro typically runs $350-$650 for a complete residential system, and most jobs are scheduled within a week of your call. We’re Kestrel Air Duct Cleaning, part of the Kingswell family of companies founded in 2004, and our crews serve San Leandro from our Bay Area dispatch office. If your home sits near the I-880 corridor or down in the Bay flatlands, you’ve probably noticed musty odors when the furnace kicks on or weak airflow in the back bedrooms. That’s not normal, and it’s usually fixable. Call us at (469) 972-3151 for a free estimate with a written price before any work begins.
San Leandro’s older housing stock, persistent marine-layer humidity, and heavy industrial traffic create duct problems we don’t see in drier inland cities. We’ve cleaned ducts in Washington Manor homes with original 1958 sheet-metal trunk lines, reattached separated flex connectors in Estudillo Estates crawl spaces, and pulled decades of diesel particulate from rigid duct systems along East 14th Street. Local conditions here demand local knowledge.
Why Kestrel Air Duct Cleaning Is San Leandro’s Preferred Air Duct Cleaning Company
We’ve built our reputation in San Leandro on showing up in the window we promised and putting the price in writing before touching a single vent. Our Air Duct Cleaning in San Leandro customers get the same Kingswell Guarantee that governs every job: written price, defined arrival window, clean job site, and a written guarantee with a free return visit if anything fails within the guarantee period.
Our technicians are background-checked, uniformed, and trained on Rotobrush rotary brush systems, Nikro negative-pressure units, and Abatement Technologies HEPA filtration. They know San Leandro’s specific failure modes: corroded joints in 60-year-old rigid trunk lines, mold-positive inspections in uninsulated crawl-space ducts, and flex connectors pulled apart by decades of seismic settling on soft Bay-margin soils. That expertise means we diagnose the real problem instead of selling a fogging treatment that masks symptoms.
Calls are answered by a live person, 24/7. No automated queue, no callback tag. When you’re staring at a water stain around a ceiling vent or smelling mildew every time the AC cycles, you want to talk to someone who can schedule a technician, not leave a message in a digital void.
Air Duct Cleaning Services in San Leandro
Air Duct Cleaning Services in San Leandro address the specific contamination patterns created by this city’s aging housing stock and industrial air exposure. Our process begins with a video inspection of your supply and return runs, followed by source removal using mechanical agitation and negative-air extraction. A typical residential system in San Leandro runs $350-$550 for a full cleaning, with larger homes or heavily contaminated systems reaching $650.
Residential Duct Cleaning
Most San Leandro homes we serve are 1,200-2,000 square foot tract houses built between 1945 and 1968. These systems usually have 8-14 vents and a single return. We clean the full supply and return network, including the plenum and main trunk lines, using Rotobrush agitation tools to dislodge debris from duct walls while Nikro negative-pressure units pull contaminants out of the living space. Abatement Technologies HEPA filtration captures particles as small as 0.3 microns during the process.
Commercial Duct Cleaning
San Leandro’s commercial buildings along Davis Street and Marina Boulevard face accelerated particulate loading from the nearby port and freight traffic. We scale our equipment to multi-zone systems and coordinate around business hours to minimize disruption. Written scope and price are agreed before any work begins.

HVAC Duct Cleaning in San Leandro
HVAC Duct Cleaning in San Leandro requires attention to components beyond the visible vents, especially in homes with original forced-air systems that predate modern sealing standards. Our technicians inspect the air handler, evaporator coil, and blower assembly as part of a complete cleaning, since contamination in these areas recirculates immediately after the ducts are cleaned. A full HVAC duct cleaning with component access typically runs $450-$650 in San Leandro.
Supply Duct Cleaning
Supply ducts deliver conditioned air to your rooms. In San Leandro’s older homes, we frequently find that supply runs have never been cleaned since installation, with compacted debris reducing airflow by 30% or more in individual branches. We use brush agitation to break loose this buildup, then extract it under controlled negative pressure.
Return Duct Cleaning
Return ducts pull air back to the air handler and typically run dirtier than supply lines, since they handle unfiltered household air. In San Leandro homes near the I-880 corridor, return ducts also accumulate diesel particulate and industrial pollutants that standard filters don’t catch. Cleaning these runs improves system efficiency and reduces the particulate load on your air handler.
Trusted Brands We Service in San Leandro
We clean duct systems connected to all major HVAC brands, and we stock Honeywell and Aprilaire filtration products for San Leandro homeowners who want to maintain cleaner air between service visits. Our technicians carry Guardsman indoor-air-quality accessories on their trucks, so upgrades like higher-MERV filters or media air cleaners can often be installed during the same visit. For persistent humidity issues in Bay-flatland homes, we can recommend Honeywell whole-home dehumidification options sized to your existing system. Parts and filters for these brands are available through our Bay Area supply chain with fast turnaround, so you’re not waiting weeks for a specialty order.
Common Air Duct Cleaning Problems We See in San Leandro Homes
- Mold growth in uninsulated crawl-space ducts. San Leandro’s marine layer creates condensation cycles inside uninsulated ductwork that drier inland cities simply don’t experience. We find mold-positive inspections routine in Bay-flatland homes, not exceptional.
- Separated flex connectors dumping air into crawl spaces. Decades of seismic settling on soft Bay-margin soils pull original 1950s-60s flex duct connections apart at the plenum. Homeowners notice weak airflow in rear bedrooms; the real problem is conditioned air pouring into the dirt below the house.
- Diesel particulate accumulation from I-880 freight corridor. San Leandro sits in one of California’s busiest truck routes. Rigid sheet-metal trunk lines in older homes collect this industrial debris at rates exceeding sheltered East Bay neighborhoods, and vacuum-only cleaning without brush agitation leaves it stuck to the walls.
- Corroded joints in 60-80 year old sheet-metal trunk lines. Original ductwork in Washington Manor and Estudillo Estates homes often lacks sealed connections required by current Title 24 standards. Cleaning reveals these failures and allows us to flag needed sealing or repair work.
Pricing for Air Duct Cleaning in San Leandro, CA
Most San Leandro homes run $350-$550 for a complete residential air duct cleaning. Larger systems or homes with heavy contamination from decades of deferred maintenance reach $650. Full HVAC duct cleaning with air handler and coil access typically runs $450-$650. Commercial systems are priced by scope after inspection.
What moves you within these ranges: square footage and vent count, accessibility of ductwork (crawl-space work takes longer than basement access), contamination level, and whether separated connections or corroded joints need repair before cleaning is effective. We give one flat price per system, agreed in writing before work starts. No per-vent pricing, no door-step revisions, no fogging upsells presented as necessary. Every estimate includes before-and-after photos of your own ducts so you can verify the work.
Call (469) 972-3151 for a free estimate. We’ll ask about your home’s age, location in San Leandro, and any symptoms you’ve noticed, then schedule a technician to inspect and quote.

FAQs About Air Duct Cleaning in San Leandro
San Leandro’s persistent marine layer humidity and pronounced diurnal temperature swings create condensation inside uninsulated ductwork that drier inland East Bay cities like Livermore or Pleasanton rarely experience. That moisture cycle feeds mold growth and dust-mite accumulation as a routine finding, not an outlier. If your home sits in the Bay flatlands and you smell mustiness when the system runs, a video inspection is the right first step. Call (469) 972-3151 for a free estimate.
Genuine source removal physically dislodges and extracts diesel particulate and industrial debris from duct walls using brush agitation and negative-air extraction. A fogging treatment deposits chemicals that may temporarily mask odors but leaves the particulate in place, where it recirculates once the system runs. In San Leandro’s I-880 corridor homes, we’ve found vacuum-only cleaning also fails because compacted industrial debris adheres to rigid sheet-metal trunk lines without mechanical agitation. We use Rotobrush tools specifically for this reason. Call (469) 972-3151 to schedule source removal.
Original 1950s rigid sheet-metal ducts in Washington Manor can almost always be cleaned successfully; the question is whether corroded joints and disconnected sections also need sealing or repair to meet current Title 24 standards. We inspect with a camera before quoting, so you’ll know the full condition before any work begins. A typical full cleaning runs $350-$550, with sealing work quoted separately if needed. Call (469) 972-3151 for an inspection.
Weak airflow in rear bedrooms, uneven heating or cooling across rooms, and utility bills that seem high for your usage are common indicators. In San Leandro’s crawl-space homes, decades of seismic settling on soft Bay-margin soils often pull original flex duct connections apart at the plenum. We verify this with a camera inspection that shows you the separation directly. One Washington Manor customer called us about weak rear-bedroom airflow; our tech found a 1958 flex connector completely separated, dumping conditioned air into the crawl space for years. Call (469) 972-3151 if you’re seeing these symptoms.
Homes in San Leandro’s industrial freight corridor with original ductwork typically benefit from cleaning every 3-5 years, sooner if you notice musty odors, visible dust emission from vents, or worsening allergy symptoms. The combination of diesel particulate loading and aging uninsulated ductwork creates faster contamination buildup than in cleaner-air environments. Homes with upgraded filtration and sealed duct systems may extend to 5-7 years. Call (469) 972-3151 and we’ll assess your specific system and location.
