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 Air Duct Cleaning Across San Diego
Air duct cleaning in San Diego typically costs $349 – $649 for a full single-system home, and most jobs are completed in 3 – 5 hours. We at Cardinal Air Duct Cleaning work across the entire metro, from Ocean Beach to Rancho Bernardo, and we do not charge per vent. You get one written flat price for the whole system before a single duct is touched. Call (737) 727-2314 for a free estimate and a live booking window you can track from your phone.
San Diego homes carry what the ocean gives them. The marine layer settles salt and moisture into ductwork in ways inland cities never see. Our crews live here, drive these freeways daily, and know exactly what that means for your air handler, your registers, and the air you breathe. We do not send a truck from outside the county and hope for the best. We schedule from our San Diego office, and the technician who arrives is background-checked, uniformed, and will introduce himself by name before stepping inside.
Key takeaways:
- Full-system air duct cleaning in San Diego runs $349 – $649 for a typical home, regardless of vent count.
- One flat price per system, written down, before work starts. No per-vent math at the door.
- Coastal San Diego homes accumulate salt-crystal buildup and rusted register screws that inland homes never deal with.
- Before-and-after photos of your own ducts are included with every job.
- Every booking carries the 365-Day Done Right Promise. If it is not right, we return and correct it at no charge.
Why Cardinal Air Duct Cleaning Is San Diego’s Preferred Air Duct Cleaning Company
San Diego homeowners call us because we name the price before we arrive. Not a range that tightens when the truck pulls up. A written number for the entire system, agreed to before work begins, that does not change at the door. That is the Relay Standard, and it applies to every booking without exception. No per-vent surcharges. No “we found something extra” conversations. You know the total, the technician knows the total, and the invoice you pay by link at the end matches the quote you approved at the start.
Our crews carry professional-grade equipment, not truck-mounted shop vacs. We run Rotobrush rotary brush systems and Abatement Technologies HEPA containment units because a San Diego home with marine-layer dust needs real negative-pressure extraction. That means the loosened debris goes straight into the vacuum, not back into your living room. The technician who shows up is licensed, background-checked, and in uniform. You will know his name before he opens the door.
Omar Haddad leads our San Diego operation. Every job we complete is backed by the 365-Day Done Right Promise. If the work is not right within a full year, we return and make it right at no charge. That is not a limited offer. It is our standing policy on every duct cleaning, every HVAC cleaning, and every dryer vent cleaning we perform. The Relay Home Co. family was founded in 2005, and the Visibility Guarantee we operate under is simple: live trackable arrival time, photo proof of the work, and a digital invoice you can pay from your phone.
Commercial Air Duct Cleaning in San Diego
Commercial Air Duct Cleaning in San Diego runs $0.18 – $0.35 per square foot for most office, retail, and restaurant spaces, with most small commercial jobs landing between $850 and $2,400. What a commercial job here involves is different from a house. High-traffic retail spaces near Mission Valley pick up construction dust from the constant roadwork and parking-garage exhaust. Restaurants in the Gaslamp Quarter deal with grease-laden air that coats ducts in a film residential systems never see. We run the same Rotobrush agitation and HEPA negative-pressure extraction, but the job is larger, takes longer, and requires scheduling around business hours.
Supply and return volumes at scale
Commercial systems push far more cubic feet per minute than a home. That means the supply side carries visible dust accumulation faster, especially in buildings near the I-5 and I-8 corridors where freeway particulate is constant. Our crews inspect both supply and return sides before and after, and you get photo documentation of every trunk line.
Phased work for open businesses
We can clean a retail space or office in phases, section by section, so you do not close for an entire day. A dental practice in La Jolla does not want patients walking through a work zone. We schedule around your hours, mask off the area, and keep the front door open while we work the zones behind it.
Air Duct Cleaning Services in San Diego
Air Duct Cleaning Services in San Diego means the full run: supply ducts, return ducts, the air handler, the blower motor, and every register in the house. Our crews set up negative pressure with a HEPA vacuum at the air handler, then feed rotary agitation tools through each line. The dust, pet hair, and salt crust come out into the vacuum, not into the room. A typical single-family home in San Diego takes 3 – 5 hours, and the price is $349 – $649 for the whole system, not per vent.
Supply and return duct cleaning
Supply ducts push conditioned air out. Return ducts pull room air back in. Both collect dust, but returns in San Diego homes collect more pet hair and fine dust because they pull from living spaces. We clean both, photograph both, and show you the before-and-after from the camera inside the duct.

Video inspection before and after
We run a camera through your ductwork before we start and again when we finish. You see what was in there and what it looks like after. If the camera finds a disconnected joint or a crushed flex line in a crawlspace, we will tell you and quote the repair separately before doing anything.

Trusted Brands We Service in San Diego
We service and install filtration components from Aprilaire, Guardsman, and Rotobrush systems, and we keep common replacement parts in our San Diego stock for faster turnaround on San Diego jobs. If your system has an Aprilaire media filter housing or a Guardsman UV air purifier, our technicians know the equipment and carry compatible filters and bulbs. That means fewer trips and less waiting when a homeowner off Genesee Avenue or in Point Loma needs a part we can pull the same day.
Common Air Duct Cleaning Problems We See in San Diego Homes
- Marine-layer salt crust on registers. Homes from La Jolla to Imperial Beach develop visible white salt crystals on register screws and faces. These rust, seize, and eventually snap when you try to remove the register. We replace the rusted hardware and clean the duct interior.
- Dust and pet hair matted in return ducts. Returns in older homes throughout Clairemont and North Park collect a dense felt of hair and dust because the return pulls from the living space. This restricts airflow and forces the blower to work harder.
- Musty odor from a wet air handler pan, not the ducts. In coastal San Diego’s humid air, condensate pans stay damp and the drain line clogs. The smell then circulates through the ducts even after they have been cleaned. Camera inspection finds the real issue.
- Construction dust in newer developments. Homes in Otay Ranch and Carmel Valley built in the last decade often have drywall dust and paint overspray inside the ducts from the original build. Builders do not clean after themselves. We do.
Pricing for Air Duct Cleaning in San Diego, CA
Full-system air duct cleaning for a typical single-family home in San Diego runs $349 – $649. That is one flat price for the entire home: supply ducts, return ducts, air handler, and every register. Commercial spaces run $0.18 – $0.35 per square foot, with most smaller storefronts and offices landing between $850 and $2,400. The factors that move the number are system size, access difficulty, and the age of the home. A 1,200-square-foot condo in Mission Valley takes less time than a 3,200-square-foot two-story in Scripps Ranch with ducts in a tight attic. We do not charge per vent. We never have. Free estimates are available by phone at (737) 727-2314.
If you are comparing quotes, ask each company one question: is this the total I will pay for the whole system? A per-vent price invites math games at the door. Our answer is always yes, and it is in writing before we start.

FAQs About Air Duct Cleaning in San Diego
Every 4 – 7 years for most San Diego homes, not annually, not every two years. Coastal homes in La Jolla, Point Loma, and Imperial Beach may lean toward the shorter end because salt-laden marine air accelerates corrosion and buildup. Homes with multiple shedding pets or recent remodeling should push that closer to 3 – 4 years. If you are not sure whether your system needs it, we will run a camera inspection and show you what we see before recommending a cleaning. Call (737) 727-2314 to schedule that inspection, and the estimate is free.
Per system. Always. One flat price for your entire duct system, written down before work starts, and it does not change at the door. We have cleaned homes with 8 vents and homes with 22 vents in San Diego, and the price is the same for the system if the square footage and access are similar. Per-vent pricing is how customers in North Park and Mira Mesa end up paying wildly different totals for the same single-system job.
Supply ducts, return ducts, the air handler, the blower motor, and every register in the home. We set up negative pressure extraction so debris goes into a HEPA vacuum and not back into your rooms, run rotary agitation through each line, clean the blower and air handler cabinet, wipe down every register, and replace rusted register screws where the marine layer has done its work. You get before-and-after photos of your own duct interiors. The whole job runs $349 – $649 for a typical home.
Because the ducts were not the source. In coastal San Diego homes, the usual cause is a wet air handler pan or a clogged condensate drain line. The dampness creates the smell, and the blower pushes it through the ducts every time the system runs. If a previous cleaning did not inspect the air handler and drain pan, the smell will come right back. Our camera inspection checks the pan, the line, and the duct interiors together so we fix what is actually causing the odor. Call (737) 727-2314 and we will walk you through what to look for.
We cannot promise same-day service. Duct cleaning is a scheduled job that takes several hours and requires proper setup, not a quick service call. What we can promise is a live booking window you can track, so you know exactly when the crew arrives, and a written price before any work begins. A live person answers our phones 24/7. Tell us your availability and we will get you on the schedule for the soonest open window.
Real Duct Cleaning, Real Pricing, Real Proof
In a 1970s ranch house off Mount Abernathy Avenue in Clairemont, we set up negative pressure with a Rotobrush and Abatement Technologies HEPA vacuum, then ran agitation tools through the supply and return ducts. What came out was a mat of dust, pet hair, and marine-layer salt crust from a system the homeowner described as “always musty.” After cleaning the air handler, blower motor, and every register, we replaced the rusted screws at two hallway vents and showed before-and-after photos of the duct interiors, which cleared visibly from gray-black to bare metal. That is what a real San Diego duct cleaning looks like. No shortcuts, no per-vent math, no vague promises.
If your San Diego home has ducts that have not been looked at in years, call (737) 727-2314. We will give you a written price for your whole system, answer every question directly, and book you a live window you can track from your phone. Before-and-after photos come standard. So does the 365-Day Done Right Promise.
