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.

AfterHow Much Does Air Duct Cleaning Cost in San Diego?
Air Duct Cleaning in San Diego typically costs $350 to $700 for an average single-family home with one HVAC system, and most jobs land near the middle of that range. Smaller condos and townhomes with a single short duct run often come in between $250 and $400. Larger homes in inland neighborhoods with two systems, long attic runs, or years of built-up dust usually run $700 to $1,200. Those are written prices before work starts, not teasers that move once the technician is inside.
We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, serving San Diego since 2004. What follows is a straight breakdown of what drives the number up or down in this market, what you should expect to see on a written quote, and how to tell whether the price in front of you is real.
Key Takeaways
- Most San Diego homes fall between $350 and $700 for standard air duct cleaning.
- Homes with two HVAC systems, long duct runs, or heavy buildup commonly reach $700 to $1,200.
- Dryer vent cleaning runs $125 to $250 as an add-on.
- Duct sealing, when needed, adds $400 to $900 depending on how many leaks are found.
- You should always get a written price before any work begins. That’s how we’ve operated since day one.
Air Duct Cleaning Cost Breakdown (2026)
Here’s what San Diego homeowners are paying in 2026 for each piece of the job. These ranges reflect the local market, not national averages pulled from a trade magazine.
| Service | Typical Cost Range | Notes |
|---|---|---|
| Standard air duct cleaning (single system) | $350 – $500 | Up to 10 vents; most condos and smaller homes |
| Air duct cleaning (larger home, single system) | $500 – $700 | 11 – 20 vents; common in Clairemont, Mira Mesa, Rancho Peñasquitos |
| Two-system home | $700 – $1,200 | Typical for two-story homes in Scripps Ranch, Carmel Valley, Poway |
| Dryer vent cleaning | $125 – $250 | Depends on run length and roof vs. wall termination |
| Duct sealing (mastic + mesh) | $400 – $900 | Priced by number of leaks found during inspection |
| Extra vent (beyond quoted count) | $18 – $35 per vent | Should be written into the original quote, not added at the door |
| Return-side cleaning | $60 – $150 | Often skipped by low-bid crews; it’s where a lot of debris sits |
| Sanitizing or deodorizing treatment | $100 – $300 | Optional; useful after pets, smoke, or water intrusion |
What drives the price up: square footage, number of vents, number of HVAC systems, how long the duct runs are, whether there’s a second story, and how much debris has accumulated. Homes near the coast tend to have less dust load because windows stay closed and humidity is stable, but they also see more salt-air corrosion on metal duct components, which sometimes turns up leaks during inspection. Inland neighborhoods like El Cajon, Santee, and Poway deal with heavier dust from dry air and nearby open ground, so vents there fill up faster. For Bay Area pricing, see How Much Does Air Duct Cleaning Cost in San Jose, CA? (2026 Price Guide).
What doesn’t drive the price up: whether the technician is wearing a uniform or whether the truck says Rotobrush on the side. Those things should be there regardless. If a quote is meaningfully cheaper than everyone else’s, the difference is usually in what they’re skipping – the return side, the plenum, or the negative-air containment that keeps debris from being pushed into your living room.
What Affects Air Duct Cleaning Pricing in San Diego
- Home size and vent count. A 1,200-square-foot condo in Hillcrest might have eight vents and one handler. A 2,800-square-foot home in Del Cerro could have twenty vents across two systems. The labor and time difference is real, and it shows up in the price.
- Number of HVAC systems. Each system has its own return, plenum, and supply network. A second system roughly adds $300 to $500 to the job because it doubles the work.
- Duct accessibility. Ducts buried in a low attic with limited clearance, or routed through tight crawlspaces, take longer to reach and connect equipment to. San Diego’s older housing stock in North Park and Normal Heights often has this problem – original ductwork from the mid-century that wasn’t designed with service access in mind.
- Level of contamination. If you’ve just finished a remodel, the ducts are full of drywall dust. If you’ve had a pet for a decade, that’s a different cleaning. If there was water intrusion after a winter storm, there may be microbial growth that requires more than standard cleaning. Contamination depth affects time on site.
- Duct material and condition. Flexible duct runs clean differently than rigid sheet metal. Old, damaged flex duct may need repair or replacement rather than cleaning, which changes the scope. We tell you what we find before we do any of it.
- Additional services. Dryer vent cleaning and duct sealing are separate line items. Both are worth doing, but they should be quoted separately so you can see what you’re paying for and decide what to prioritize.
We use equipment from Rotobrush, Nikro, and Abatement Technologies on every job. The rotary brush system that Rotobrush makes physically scrubs the interior walls of the duct – think of it as a spinning brush on a flexible shaft that travels the length of the run. The Nikro negative-air machine creates suction at the main trunk so loosened debris gets pulled out of the system rather than blown into your rooms. When filtration upgrades make sense, we work with Honeywell, Aprilaire, and Guardsman products. None of this is exotic – it’s standard professional gear. But it’s the difference between cleaning ducts and just running a shop vac over the registers.
How to Save on Air Duct Cleaning
The biggest savings come from knowing exactly what you need before you call. Here’s what actually helps.
- Get more than one quote, but read the scope, not just the number. A $199 quote that doesn’t include the return side, the plenum, or any containment isn’t a cheaper version of the same job. It’s a different job.
- Bundle dryer vent cleaning with your duct cleaning. The technician is already on site with the equipment. Adding the dryer vent while we’re there typically costs less than scheduling it as a separate visit.
- Address duct sealing at the same time if leaks are found. Sealing leaks reduces the load on your HVAC system, which means the cleaning you just paid for lasts longer before dust re-accumulates. The two services work together.
- Ask for a written price before work starts. This isn’t a negotiation tactic – it’s a standard. If a company won’t put the number in writing before touching your system, that tells you something.
- Don’t skip the inspection. A proper inspection tells you whether you need cleaning at all, or whether you have a leak problem that’s pulling dust in from the attic. Fixing the source is cheaper than cleaning the symptom repeatedly.
We offer free estimates on every job. Call (361) 326-5060 and we’ll give you a real range for your home based on square footage, vent count, and system setup – before anyone shows up.
When Does Air Duct Cleaning Make Sense in San Diego?
Not every home needs duct cleaning every year. Some don’t need it at all. Here’s when it’s worth the money in this market.
If you’ve just completed a remodel, yes. Drywall dust and construction debris get pulled into the return the moment the HVAC runs. In San Diego’s older neighborhoods – North Park, Golden Hill, South Park – remodels are constant, and we see the same pattern: fine white dust circulating for weeks after the job is finished because nobody cleaned the ducts.
If you’ve lived in the home for five or more years and never had the ducts cleaned, it’s worth an inspection. We’ve pulled everything from pet hair to Legos to a desiccated lizard out of return trunks. If the system has never been opened up, there’s material in there.
If you’ve had water intrusion or a roof leak, yes – especially after a heavy winter rain. Moisture in ductwork creates conditions for microbial growth that standard vacuuming won’t address properly. That’s not something to put off.
If your energy bills have crept up and the house doesn’t hold temperature the way it used to, get an inspection. It may be duct leaks rather than dirty ducts. Sealing is the fix in that case, and we’ll tell you that instead of selling you a cleaning you don’t need.
If none of those apply and your system is running fine, we’ll tell you that too. Cleaning ducts that don’t need cleaning isn’t doing you a favor.
What You Should Expect From a Written Quote in San Diego
Any quote you get should include the following, in writing, before work begins:
- Number of vents included in the price
- Number of HVAC systems being serviced
- Whether the return side and plenum are included
- Whether dryer vent cleaning is included or separate
- Whether duct sealing is included, quoted, or not addressed
- The total price
If the quote is verbal, it’s not a quote. If the price changes when the technician arrives, that’s a different business than the one you called. Every job we do gets a written price up front, and that price doesn’t move at the door. It’s covered by our 365-Day Done Right Promise: if the work fails within a year, we come back and make it right at no charge, including a free second visit. That’s not a slogan – it’s written on every job.
Our technicians are background-checked and uniformed. You’ll know who’s coming to your home before they arrive. Our phones are answered by a live person 24 hours a day, seven days a week – no voicemail loops, no callback queues. And we leave the site clean. Those aren’t extras. They’re the standard.

FAQs – Air Duct Cleaning Cost in San Diego
How much does air duct cleaning cost in San Diego?
Air duct cleaning in San Diego costs $350 to $700 for most single-family homes, with larger two-system homes running $700 to $1,200. Condos and smaller homes typically fall between $250 and $400. Call (361) 326-5060 for an exact quote on your home – estimates are free.
Is air duct cleaning worth the money?
It’s worth it when there’s a reason to do it – after a remodel, after water intrusion, or when the system hasn’t been cleaned in five or more years. If your ducts are clean and your system is running fine, we’ll tell you that instead of selling you a job you don’t need. Call (361) 326-5060 and we’ll help you decide.
How long does air duct cleaning take?
A standard single-system home takes 2 to 3 hours. Two-system homes or homes with heavy contamination run 3 to 5 hours. The technician should give you a time estimate when the written price is delivered. Call (361) 326-5060 to schedule.
Does duct cleaning help with allergies in San Diego?
It can help by removing accumulated dust, pollen, and pet dander from the duct system, which reduces what gets circulated through the home. In San Diego, coastal homes deal with less dust load than inland homes, but pollen season affects the whole county. If allergies are the primary concern, we’ll inspect first and tell you whether cleaning is the right answer. Call (361) 326-5060 for a free estimate.
How often should air ducts be cleaned in San Diego?
Every 3 to 5 years for most homes, more often if you have pets, have recently remodeled, or live in an area with higher dust loads like El Cajon or Santee. Homes near the coast often stretch closer to five years because dust accumulation is slower. Call (361) 326-5060 and we’ll give you a straight answer for your specific home.
Can you clean my dryer vent at the same time?
Yes. Adding dryer vent cleaning to a duct cleaning visit typically costs $125 to $250 and saves you a separate service call. It’s also the single most overlooked fire-safety item in most homes. Call (361) 326-5060 to bundle both.
Do you offer duct sealing as well?
Yes. Duct sealing runs $400 to $900 depending on how many leaks we find and how accessible they are. Sealing is priced separately so you can see exactly what you’re paying for. Call (361) 326-5060 and we’ll include an inspection in your free estimate.
Why do some San Diego companies quote $99 or $199?
Because the scope is different. A $99 quote usually covers a handful of vents, skips the return side and plenum, and may not include proper negative-air containment. It’s not a cheaper version of the same job – it’s a smaller job. We quote the full scope in writing before we start. Call (361) 326-5060 for a real price.
Are your technicians background-checked?
Yes. Every Hollis technician is background-checked and uniformed, and you’ll know who is coming to your home before they arrive. We also answer the phone with a live person 24 hours a day, so you’re never stuck in a callback queue. Call (361) 326-5060 for your free estimate.
What is the 365-Day Done Right Promise?
Every job we do is covered in writing for a full year. If the work fails within that period, we come back and make it right at no charge, including a free second visit. That’s the standard, and it’s written on every job. Call (361) 326-5060 to schedule your free estimate.
