Styles & brands we work with
Air Duct Cleaning Services
Return Duct Cleaning is part of our Air Duct Cleaning Services, which cover the full removal of accumulated dust, pet dander, pollen, and debris from the supply and return ductwork that moves conditioned air through your San Diego home. Over months and years, these particles build up along duct walls and get pushed back into your living space every time the blower cycles on. Kestrel Air Duct San Diego uses negative-air extraction to pull contaminants out rather than pushing them around, paired with rotary brush agitation from Rotobrush systems to dislodge debris stuck to the duct wall. Most San Diego homes run between $350 and $650 for a complete cleaning, depending on the number of returns, the accessibility of the main trunk line, and the age of the system.
Full-System Cleaning
We clean the entire duct path: return registers, main trunk line, branch runs, and supply boots. Each register is sealed during the process so loosened particles exit through the vacuum collection system, not into your hallways.
Post-Cleaning Verification
Before we declare a job done, we walk you through the before-and-after photos of your own ducts. You’ll see what came out and what the interior looks like after the work is finished.

HVAC Duct Cleaning
HVAC Duct Cleaning focuses on the portion of your heating and cooling system that actually distributes air: the ducts, plenums, registers, and the interior surfaces of the air handler cabinet that sits in the path of moving air. In a San Diego climate, most homes run their HVAC fan year-round even when the compressor is idle, which means fine dust gets pulled continuously through the system and settles in low-velocity corners. Our technicians use Abatement Technologies HEPA filtration during cleaning to keep loosened particles out of the living space while the job is underway. A full HVAC duct cleaning runs between $350 and $650 for most San Diego homes, with larger multi-zone houses quoted on inspection.
Complete Path Coverage
We treat the entire path of airflow, including the return drop, the blower compartment, the supply plenum, and every branch line off the main trunk. Leaving even one section untouched lets dirty air re-contaminate freshly cleaned ducts within weeks.
Filter and Fan Check
As part of an HVAC-specific cleaning, we inspect the blower wheel for dust buildup that restricts airflow and forces the fan to work harder. A clean blower moves air more efficiently and puts less strain on the motor.
Vent Cleaning
Vent Cleaning addresses the visible registers and return grilles where air enters and exits your living space, along with the first few feet of duct behind them. These surfaces trap lint, hair, and dust that can become visible within months, especially in homes with pets or high ceiling-fan use. Kestrel Air Duct San Diego cleans register faces, removes and washes removable grilles, and clears the throat of each vent so air moves freely. Vent cleaning as a standalone service typically runs $150 to $300 depending on vent count and accessibility, though it’s often bundled with a full duct cleaning at a lower combined rate.
Visible Grille Restoration
Over time, supply registers collect a grey film that defies standard household dusting. We clean both the front face and the back side where dust clings unseen and gets reintroduced with every cycle.
Airflow Obstruction Removal
Behind many vents, toys, dryer sheets, or construction debris partially block the airflow. In San Diego homes built during the 1990s and early 2000s, we regularly find drywall scraps that fell into wall cavities during construction and now restrict delivery to individual rooms.
Air Duct Repair
Air Duct Repair fixes the mechanical problems that let conditioned air escape before it reaches your rooms: separated joints, crushed flex runs, punctured trunks, and poorly sealed connections between duct sections. In many San Diego homes, the ducts run through unconditioned attics that hit 130°F in summer, and any gap in the metal or flex fabric means air you paid to cool is dumping into the attic instead of the bedroom. Our technicians inspect every accessible joint in the system during a cleaning and flag leaks, disconnected runs, and crushed sections. Repair pricing depends on what we find: a separated joint might run $75 to $150, while replacing a crushed section of flex duct can run $200 to $400.
Leak Detection and Sealing
Cold ducts sweating in a hot attic is a classic San Diego symptom of insufficient insulation and small leaks. We test visible connections and seal them with mastic or metal tape rated for HVAC use, not the grey vinyl tape that dries up and fails in three summers.
Crushed and Disconnected Runs
Santa Ana wind season and roof work often leave flex duct pinched or pulled apart. A disconnected run means one room gets no airflow while the rest of the house cools unevenly. We locate the break and restore the connection or replace the damaged section.
Ductwork Cleaning
Full System Cleaning is the most thorough level of service we offer, targeting the entire duct system’s interior surfaces, not just the visible parts. This means the main trunk, every branch line, the return drop, the plenums on both sides of the air handler, and the boots behind every register. Kestrel Air Duct San Diego pairs Nikro negative-pressure vacuum units with Rotobrush rotary brush systems to agitate and extract, and we use Abatement Technologies HEPA filtration during the work to keep your indoor air protected while the job runs. Whole-system ductwork cleaning runs between $350 and $650 for a typical San Diego single-family home, which includes both returns, all supplies, and the blower compartment.
Negative-Pressure Containment
The vacuum unit creates continuous suction at the register while the brush works inside the duct, so debris is pulled into collection rather than blown into rooms. This is the difference between professional ductwork cleaning and a surface dusting.
Multi-Level and Attic Systems
San Diego homes on canyons and hillsides often have long attic runs or split systems with multiple returns. We plan each cleaning around the actual layout of your ductwork, not a one-size-fits-all pattern, and the written price reflects the specific configuration before work begins.
Air Duct Inspection
Air Duct Inspection is a visual and diagnostic walkthrough of your duct system to identify leaks, contamination, mold, pest activity, and airflow problems before they become expensive repairs. You need an inspection if you’ve never seen the inside of your ducts, if rooms heat or cool unevenly, if your energy bills climb in mild months, or if you’ve recently completed renovation work. Kestrel Air Duct San Diego inspects with camera equipment that lets you see the actual condition of the ducts yourself, and we document findings with photos so you’re making decisions based on evidence, not a sales pitch. A standalone inspection runs $99 to $199 depending on system size and access difficulty, and that fee is credited toward the cleaning if we proceed with the work.
Camera Walkthrough
We push a small camera into the main trunk and branch lines so you and our technician can both see the buildup, damage, or contamination in real time. You’ll know exactly what you’re paying to address because you’ve seen it with your own eyes.
Post-Renovation Checks
After any remodel, drywall dust, sawdust, and debris find their way into open ducts. An inspection after construction catches this before the blower redistributes it through the whole house as a fine white film on every surface.
Residential Air Duct Cleaning
Residential Duct Cleaning serves single-family homes, townhomes, and condos throughout San Diego, from 1920s bungalows in North Park to 2000s tract homes in Scripps Ranch and modern builds in Carmel Valley. Homes with kids, pets, carpet, or anyone dealing with allergies benefit from periodic cleaning because these conditions add more airborne particles to the system than the filter alone can catch. Our technicians wear boot covers inside your home, lay drop cloths at each work point, and clean up after themselves as part of The Kingswell Way code that governs every visit. Residential duct cleaning runs $350 to $650 for a full system in most San Diego homes, and the written price you receive before the job is the price you pay when it’s done.
Homes with Pets and Allergies
Pet dander is sticky and fine, and it accumulates inside ducts even in homes where the filter is changed monthly. A resident with asthma or allergy symptoms that worsen at home but improve when away is a strong signal that the ductwork needs attention.
Older and Historic Homes
San Diego’s older housing stock, especially the 1920s and 1930s homes in central neighborhoods, often has original metal ducts with decades of layered dust. These systems clean beautifully with rotary brush agitation and negative-air extraction, and our technicians know how to work with older register styles without damaging original fittings.
Commercial Air Duct Cleaning
Commercial Duct Cleaning handles the larger, more complex duct systems in San Diego offices, medical suites, retail spaces, restaurants, and light industrial buildings. Commercial systems move more air, run longer hours, and often share ductwork across multiple rooms or tenants, which means the contamination spreads further and the cleaning requires larger equipment and careful scheduling around business hours. Kestrel Air Duct San Diego works with property managers and business owners to clean after hours or on weekends when needed, and every commercial job still runs under the same Kingswell Guarantee: written price first, defined arrival window, clean job site, and written warranty. Commercial pricing starts around $800 and scales with system size, tenant count, and access complexity. We quote each commercial building individually after an inspection.
Offices and Medical Spaces
Offices with dense occupancy pump skin cells, paper dust, and tracked-in debris through the HVAC system every workday. Medical and dental suites in particular benefit from clean ducts because the air quality directly affects patients and staff, and because inspection reports create a paper trail for facility compliance.
Restaurants and Retail
Grease-laden air and high foot traffic make restaurant duct systems some of the most contaminated we see anywhere in the San Diego market. We schedule around prep hours and clean in phases so the business keeps operating with minimal disruption.

AfterBrands We Service
Kestrel Air Duct San Diego works on all makes and models of residential and light commercial duct systems, regardless of the original installer or the age of the equipment. Our technicians use Rotobrush rotary brush systems for agitation, Nikro negative-pressure units for extraction, and Abatement Technologies HEPA filtration to keep loosened particles contained during the cleaning. We’ve maintained and cleaned ducts in homes with Carrier, Lennox, Trane, Rheem, Goodman, and York equipment, and we know the common duct layouts each brand tends to use.
For homeowners who want to maintain cleaner air between service visits, we also supply Guardsman filtration and indoor-air-quality products along with Honeywell and Aprilaire options. Whether you have a newer variable-speed system or a 1990s single-stage furnace, the ductwork on the other side of the filter still needs periodic attention. If you have a brand we haven’t mentioned, we can help: the cleaning approach is determined by the duct configuration, not the badge on the air handler.
Signs You Need a Pro Right Now
- Dust returns within days of cleaning. If you dust the furniture and a fresh layer appears within 48 hours, the ducts are likely releasing accumulated particles every time the blower runs. You’re not seeing normal household dust; you’re seeing whatever has been stored in the duct walls being redistributed into the rooms.
- Rooms heat and cool unevenly. Some rooms consistently run five to ten degrees warmer or cooler than the rest of the house. This often points to a crushed flex run, a disconnected branch, or a damper that’s been closed for years and never reopened.
- Musty smell when the fan kicks on. Odor that appears only when the HVAC fan runs is typically coming from inside the ducts or the coil area, not from the room itself. If it smells like a damp crawlspace every time the air moves, the source is in the system.
- Visible lint or dust at the registers. Supply registers with grey fuzz or visible accumulation around the louvers are a direct sign that the duct interiors are loaded. What you see at the face is a fraction of what’s upstream in the run.
- Energy bills climb in mild months. When your usage stays flat but the bill rises, the system is working harder than it should. Restricted airflow from dirty ducts and a loaded blower wheel makes the fan run longer to deliver the same comfort, and that run time shows up on the invoice from SDG&E.
Our Process, Step by Step
- 1
Walkthrough and written price. We inspect the duct layout, count the returns and supplies, and identify access points to the trunk line. Then we hand you a written price for the complete job, no verbal estimates, no ranges that can change. The number on that paper is the number you pay.
- 2
Protection of the living space. Drop cloths go down at every work point, boot covers go on before we step onto carpet or hardwood, and corner guards protect walls in tight hallways. We treat your home like a work site we need to leave cleaner than we found it.
- 3
Negative-air setup and access. We cut or open access into the main trunk and return drop, connect the Nikro negative-pressure unit to create continuous suction, and seal each register during cleaning. The vacuum runs the whole time the brush is inside, so debris has one path out of your house: through the collection system.
- 4
Agitation and extraction. Rotobrush rotary brush systems work through each branch line and the main trunk, dislodging debris at the duct wall while the vacuum pulls it out behind the brush. The process runs supply by supply, return by return, until the entire system is clean.
- 5
Verification and final walkthrough. Before we pack up, we walk you through before-and-after photos of your own ducts. You’ll see what the interior looked like when we started and what it looks like when we finish. Then we hand you the 365-Day Done Right Promise in writing, with the same four commitments the Kingswell Guarantee has applied to every job since 2004.
How Much Does Air Duct Cleaning Cost in San Diego?
A full-system air duct cleaning in San Diego runs between $350 and $650 for a typical single-family home with one air handler and standard attic or crawlspace access. Homes with two or more air handlers, very long trunk runs, or difficult access can run $700 to $1,000 or more, and we’ll tell you the exact written number before any work begins. Standalone vent cleaning runs $150 to $300. Air duct inspection with camera documentation runs $99 to $199, credited toward the cleaning if we proceed.
Three things drive the price: the number of returns and supplies, the accessibility of the duct system, and the level of contamination currently in the ducts. A clean, accessible single-story system is straightforward work. A two-story home with a tight attic and 20 years of accumulated pet hair takes a different amount of labor, and that’s reflected honestly in the quote. The Kingswell Guarantee removes the gamesmanship from pricing: the written price in your hands covers the complete job, not a teaser that becomes a larger invoice once the van is in the driveway. You’ll also get the 365-Day Done Right Promise in writing, so if the work falls short within the first year, we return and make it right at no charge.

Frequently Asked Questions About Air Duct Cleaning in San Diego
Air duct cleaning is the removal of accumulated dust, pet dander, pollen, and debris from the interior surfaces of the ductwork that distributes conditioned air through your home. We use negative-air extraction to pull contaminants out and rotary brush agitation to dislodge material stuck to the duct walls, then verify the results with before-and-after photos. Call (619) 695-0424 for a free estimate on your San Diego home.
Most San Diego homes take between 3 and 6 hours for a complete cleaning, depending on system size and access difficulty. Single-story homes with attic access run faster; two-story homes with a crawlspace main trunk take longer. We’ll give you a defined arrival window and an estimated completion time when we schedule.
A full-system cleaning runs $350 to $650 for a typical single-family home, with larger or multi-zone homes quoted higher on inspection.

Yes, we clean ductwork connected to every major HVAC brand, including Carrier, Lennox, Trane, Rheem, Goodman, and York. The cleaning process adapts to the duct configuration, not the badge on the air handler. Whether your system is 5 years old or 50, we can clean it.
Duct cleaning is a scheduled service, not an emergency dispatch. We answer calls with a live person 24/7, so you can reach us any time of day to discuss your situation, and we’ll schedule the earliest available appointment that fits your needs. If you’ve had a water intrusion or construction event, call us immediately so we can inspect before contaminants harden inside the ducts.
If the cleaning falls short within one year, we return and make it right at no charge. The promise is documented in writing on every single job, and it covers the cleaning work we performed. To invoke it, call us: we’ll assess the issue and schedule the return visit under the same Kingswell Guarantee commitments that applied to the original appointment.
Clear a small working space around each register and the area near the furnace or air handler so our technicians can access the system. Move any fragile items off shelves near registers, since the brush creates minor vibration during cleaning. We handle the rest, including laying drop cloths and covering all work areas.
