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 $800 for a standard single-family home, with most homeowners landing around $475. Larger houses with two systems, heavy dust from canyon winds, or decades of buildup in older neighborhoods like North Park and Normal Heights run $850 to $1,400. That price should be in your hands in writing before anyone touches a vent.
We’re Kestrel Air Duct Cleaning, part of the Kingswell family of companies, and we’ve been doing this work under the same written standard since 2004 – the Kingswell Guarantee. That means a written price before work begins, a defined arrival window, a clean job site, and a written guarantee on the work itself. No doorstep revisions. No vanishing act after the invoice clears.
Air Duct Cleaning Cost Breakdown (2026)
Here’s what San Diego homeowners actually pay, line by line, for the 2026 market. These aren’t teaser rates or “starting at” bait – they’re the ranges we see quoted and billed across the county, from Chula Vista to Encinitas.
| Service | Typical Price Range | What It Covers |
|---|---|---|
| Single-system home (up to 2,000 sq ft) | $350 - $550 | Full supply and return cleaning, one HVAC system, standard vent count (10-18 vents) |
| Two-system home (2,000-3,500 sq ft) | $550 - $950 | Both systems, all supply and return runs, main trunk lines |
| Large or multi-level home (3,500+ sq ft) | $850 - $1,400 | Multiple systems, extended runs, attic and crawlspace ductwork |
| Extra vent beyond standard count | $12 - $22 per vent | Each additional register or return |
| Heavy buildup / post-renovation | $150 - $400 add-on | Drywall dust, construction debris, years of accumulation |
| Dryer vent cleaning | $125 - $225 | Lint removal, lint trap bypass clearing, exterior termination check |
| Mold or rodent contamination treatment | $400 - $900 add-on | Sanitizing, sealing gaps, remediation of affected sections |
So a typical three-bedroom home in Mira Mesa with one system and 14 vents usually comes in near $425 to $475. A 1970s-era house in Clairemont with original ductwork, a second story, and a system that hasn’t been touched since the Reagan administration? Closer to $900 – and worth it, because that ductwork is pushing decades of dust into every room.
What drives the price up or down: number of systems, square footage, how many vents, how dirty the ducts actually are, and whether there’s contamination (mold, rodents, construction dust) that needs more than standard cleaning. What doesn’t drive our price up: whether we’re having a slow week. The written price is the price.
What Affects Air Duct Cleaning Pricing in San Diego
San Diego isn’t Phoenix, Houston, or San Francisco, and duct pricing here reflects that. Here’s what actually moves the number in this market.
- Number of HVAC systems. You can’t clean two systems for the price of one, and a lot of San Diego homes built after 1995 have a separate upstairs unit. Each system is a separate cleaning job with its own trunk lines and returns.
- Home age and duct condition. In neighborhoods like North Park, Normal Heights, and City Heights, we routinely find 60-year-old galvanized ductwork with disconnected joints and decades of settled debris. That takes longer and sometimes needs sealing before cleaning makes sense.
- Coastal vs. inland dust load. Homes within a mile or two of the ocean deal with salt air and marine humidity, which can corrode thin duct metal and encourage mold. Inland homes in El Cajon, Santee, and Poway pull in fine canyon dust during Santa Ana wind events – that grit settles in the runs and comes back every fall.
- Access difficulty. A single-story ranch with an open attic is a straightforward job. A 1920s bungalow in Golden Hill with a low crawlspace and ducts snaking under a finished floor? That’s slower work, and slower work costs more.
- Contamination type. Plain household dust is standard cleaning. Rodent droppings, mold growth from a leak, or drywall dust from a kitchen remodel all trigger different handling – we use Abatement Technologies HEPA filtration to keep loosened particles out of your living space during the job, and that equipment is part of why contamination jobs cost more.
- Vent count. Standard is roughly one vent per 100 to 150 square feet. Big open-concept homes and additions often have extra registers nobody counted when the place was built.
One thing that doesn’t change our price: the day of the week or how the schedule looks. We quote in writing, and that number holds. If a competitor is quoting $199 over the phone and $600 at your door, that’s the pattern we exist to replace.
How the Cleaning Actually Works (and Why It Costs What It Costs)
Price makes more sense when you know what’s happening in your house for those two to four hours. We use three pieces of equipment, and each one does a specific job:
- Rotobrush rotary brush system. A spinning brush head travels through the duct, physically knocking debris off the duct walls. Think of it as scrubbing the inside of a pipe, not just blowing air through it.
- Nikro negative-pressure unit. While the brush is loosening debris, this unit pulls air out of the system and into a containment setup. Negative pressure means dust moves toward the machine instead of into your living room.
- Abatement Technologies HEPA filtration. The final stage. Air pulled from your ducts passes through HEPA filters before it’s exhausted, so fine particles don’t end up settling on your furniture.
That’s the difference between a real duct cleaning and a guy with a shop vac and a leaf blower. One takes two techs, professional equipment, and hours of careful work. The other takes forty minutes and leaves half the debris where it was. It’s also why a $150 “whole house special” is almost always a come-on – nobody can do this job properly at that price and stay in business.
You should know the safety side too: if you’ve got rodent activity, mold, or a suspected gas appliance issue anywhere near the ductwork, that’s not a DIY situation. Disturbing contaminated ductwork without containment spreads spores and droppings through the house. It’s a job for trained technicians with proper equipment, and that’s a big part of what your money pays for. See our related guide on dryer vent cleaning if your concern is lint buildup rather than air quality – it’s a shorter job with a different safety profile.
How to Save on Air Duct Cleaning in San Diego
Nobody wants to overpay. Here’s how to keep the number down without cutting corners that cost you later.
- Bundle duct and dryer vent cleaning. If you book both in the same visit, you save a trip charge and usually a bit off the total. Dryer vent cleaning alone runs $125 to $225; bundled, it’s often less.
- Get the price in writing before you book. This is the single biggest saver, and it’s not about discounts – it’s about avoiding the $199-to-$600 bait-and-switch. A written price means the number can’t move.
- Clean after renovations, not before. If you just finished a kitchen or bathroom remodel, wait until the dust settles, literally, then clean once. Cleaning twice is paying twice.
- Ask about maintenance. If you want to keep air cleaner between visits, Honeywell, Aprilaire, and Guardsman filtration and indoor-air-quality products are available. Better filtration means less debris pulls into the ducts over time.
- Book on your schedule, not a promotional deadline. We don’t manufacture urgency with countdown timers or “two slots left.” If a company is pressuring you, that’s the tell.
- Handle small contamination early. A small leak that grows mold in one section is a $400 fix. Ignore it for two years and it spreads through the trunk line – now you’re in the $900 range.
Estimates are free, and you’ll get a real number before you commit. Call (469) 972-3151 and we’ll walk you through what your specific home needs.
Repair vs. Replace: Which Makes Sense?
This comes up constantly, especially with older San Diego homes. The honest answer depends on the ductwork itself, not the price of cleaning.
If your ducts are intact and just dirty, clean them – a few hundred dollars solves the problem. If the ductwork is falling apart, that’s a different question. In homes from the 1920s through the 1960s we sometimes find duct sections that are disconnected, crushed, or so corroded from coastal humidity that cleaning them is like cleaning a sieve. In those cases it makes more sense to replace the failing sections than to keep paying to clean something that won’t hold air.
We don’t do duct replacement – our two services are air duct cleaning and dryer vent cleaning – so you won’t get a sales pitch from us to replace anything. What you’ll get is an honest answer about what we find, in writing, and a referral conversation if the situation calls for something we don’t do. That’s the Kingswell Way: say the price, show up in the window we gave, leave the place cleaner, put the guarantee in writing, and come back if it fails.
The 365-Day Done Right Promise, in Plain Terms
Every job we do is covered by the 365-Day Done Right Promise. Here’s exactly how it works, because a guarantee you can’t invoke isn’t a guarantee:
- What it covers: the work itself. If we clean your ducts and the airflow, the dust, or the result isn’t what we said it would be, we come back and make it right at no charge – within 365 days.
- What you need to do: call us at (469) 972-3151 and tell us what’s wrong. That’s it. No forms to hunt down, no fine print to argue about.
- How we respond: we schedule a return visit, and if the repair fails, the second visit is free too. That’s written into the guarantee, not a courtesy we extend at our discretion.
This is why the price on the page matters less than the price on your invoice. We’ve operated under this same written standard since 2004, across every location in the Kingswell family, from San Jose to Seattle. Each one is independently owned and operated, but they all hold to the same four promises and the same guarantee. Our technicians are background-checked and uniformed, and calls are answered by a live person 24/7 – not a voicemail queue, not an automated menu.
What About Filtration Between Cleanings?
A duct cleaning resets the clock; filtration keeps it from resetting fast. If your system uses a standard 1-inch fiberglass filter, dust that gets past it lands in your ducts and stays there. Upgrading to a better filter housing is one of the cheaper improvements you can make after a cleaning. Honeywell, Aprilaire, and Guardsman products cover the range from simple media filters to whole-home air cleaners, and we can point you toward what fits your system. The goal is fewer particles entering the ductwork in the first place, so your next cleaning is a smaller job.
We also recommend keeping an eye on the obvious stuff. Change your filter on schedule. Watch for visible dust around registers, which often means a joint has come loose. And if you notice a musty smell when the air kicks on – especially in coastal homes or after a roof leak – get it looked at before it spreads. If you’re looking at dryer vents instead of air ducts, our San Diego dryer vent cleaning page covers lint buildup and the fire risk that comes with it.
FAQs – Air Duct Cleaning Cost
How much does air duct cleaning cost in San Diego?
Most San Diego homes pay $350 to $800, with a typical single-system home landing around $475. That’s comparable to Seattle duct cleaning costs. Two-system homes run $550 to $950, and homes over 3,500 square feet with heavy buildup reach $1,400. Call (469) 972-3151 for a free written estimate exact to your home – the price won’t change at the door.
Is $99 or $199 duct cleaning a real price?
No, not for a full job. Professional equipment, two technicians, and hours of work can’t produce a real cleaning at that price – that number is usually a door-opener that becomes $500 or $600 once the technician is inside. We put the real number in writing before we start, and it holds. Free estimates at (469) 972-3151.
How long does the job take, and does that affect the cost?
A typical single-system San Diego home takes two to four hours, and a two-system home takes three to five. Time is built into the quoted price, so a slower job doesn’t mean a bigger bill later – the written number is the final number. Call us for a free estimate tailored to your layout.
Do I need duct cleaning every year?
Most homes are fine on a three-to-five-year cycle. Move to a two-to-three-year cycle if you have pets, allergies, recent renovations, or a home near the coast where humidity encourages mold. Homes inland dealing with seasonal canyon dust often do well on a fall schedule. Call (469) 972-3151 and we’ll give you an honest recommendation, not a recurring plan you don’t need.
What’s included in the written price?
Every quoted price covers the full supply and return cleaning for your listed system count, the number of vents on the quote, containment using HEPA filtration, and the 365-Day Done Right Promise in writing. Extras like extra vents, contamination treatment, or dryer vent cleaning are quoted upfront – never added at the door. Call (469) 972-3151 for your free estimate.
