Air Duct Cleaning Cost Breakdown (2026)

Here is what you should expect to pay line by line in the Pasadena market this year. These ranges reflect our own pricing data alongside what we see from other established local companies – not national chains running $59 bait-and-switch ads.

Service	Pasadena Price Range	What It Includes
Full-system air duct cleaning	$390 – $760	All supply and return vents, main trunk lines, blower compartment, and an inspection of the full system on a typical 1,500 – 2,500 sq. ft. home.
Condominium / apartment duct cleaning	$285 – $430	Systems with 8 – 12 vents, generally under 1,200 sq. ft. Common in older Pasadena condo buildings near Old Town and along South Lake Avenue.
Large home / extra vent cleaning	$650 – $1,100	Homes above 2,800 sq. ft. or with more than 20 vents, common in San Rafael Hills, Annandale, and the estates off Orange Grove Boulevard.
Dryer vent cleaning (add-on)	$89 – $160	Removal of lint buildup from the dryer duct run. We recommend it any time the duct is being done, especially on long runs common in Pasadena ranch homes.
Duct sealing (per access point)	$35 – $55	Mastic or tape sealing of accessible joints and connections while the system is open.
Standalone duct sealing	$500 – $1,400	Full-system sealing using the negative-air method, which pulls sealant into leaks throughout the ductwork.

One thing we tell every Pasadena homeowner: if a quote comes in under $250 for a full single-family home, read the fine print. Low-teaser pricing in this trade almost always means a crew shows up, opens one or two vents, and then “discovers” mold, rodent activity, or a cracked plenum that requires an upgrade. The price moves, and the homeowner is caught mid-job. Our written price does not move. That is the Garrison Standard: price it before we touch it, and stand behind the number.

What Affects Air Duct Cleaning Pricing in Pasadena

• Home size and vent count. A 900-square-foot bungalow in Northwest Pasadena might have 8 vents. A four-bedroom Colonial in Madison Heights might have 24. Every vent is a work point, and work points drive time.
• Age of the home and ductwork. Pasadena’s housing stock is older than almost any city in Los Angeles County. Many homes built before 1960 have rigid metal ducts that corrode or separate at the seams. We see this constantly in the Bungalow Heaven and Garfield Heights neighborhoods, and it adds labor when joints need resealing.
• Access to the air handler. Some Pasadena homes hide their furnace or air handler in tight attic crawl spaces or basement utility closets. If our technicians need extra time to reach the blower safely, the estimate reflects that. We flag it on the written quote before work starts – never after.
• Contaminant level. Construction dust, pet hair, and the fine soot that drifts in from the 210 Freeway corridor all build up in ductwork. Homes near the freeway or recent remodels often need a slower pass with the rotary brush, and that affects the number.
• Add-on services. Dryer vent cleaning, duct sealing, or replacing a worn filter housing all add to the total. We quote every add-on separately and in writing, so you can say yes or no with the real number in front of you.
• Season. Pasadena prices are steadiest in spring and fall. Summer and early winter tend to bring a rush of calls, and some outfits raise rates during those peaks. Our pricing stays level year-round – the quote in June is the same quote in December.

What Air Duct Cleaning Actually Involves (So You Know What You’re Paying For)

We use the negative-air method paired with a rotary brush system. Here is what that means in plain English.

The negative-air method means we connect a high-powered vacuum, in our case a Nikro negative-air machine, directly to your duct system. The machine pulls the entire system under suction while we work, so the debris we loosen gets drawn out of the duct and into the machine’s filtration – not blown into your living room. Think of it like a dentist’s suction that keeps everything moving in one direction.

The rotary brush system, ours is a Rotobrush unit, sends a spinning brush down each duct line to physically scrub the walls. Dust films that have baked onto the duct surface for a decade do not come off with vacuum alone. The combination matters, and it is the standard we have used since 2004.

After the mechanical cleaning, we inspect for gaps, cracks, and separated joints. If we find leaks, we can seal them with mastic while the system is open. Duct sealing mastic is a paste that hardens and closes the gap permanently. In a city where the summer heat pushes air conditioners hard for five straight months, unsealed ducts mean you are paying to cool your attic. In an older Pasadena home, duct leakage of 15 to 25 percent is common. Sealing it pays for itself.

On the filtration side, we stock and recommend products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. If your system has a basic one-inch filter slot, we can talk you through whether an upgrade makes sense and what it costs. We never hard-sell filtration. We show you the number and let the math speak.

How to Save on Air Duct Cleaning in Pasadena

Saving money on duct cleaning does not mean finding the lowest bid. It means not paying twice. Here is how to keep your cost down without getting burned.

• Bundle dryer vent cleaning with the duct cleaning. You will pay $89 – $160 for the dryer vent as an add-on, versus $130 – $220 as a standalone visit. It is also the single highest-fire-risk item in most Pasadena homes, so it is not the place to pinch pennies.
• Ask about duct sealing while the system is open. Sealing access points during a cleaning runs $35 – $55 each. Doing it as a separate job later starts at $500. If your home is older or your energy bills are high in August and September, get the sealing done on the same visit.
• Keep up with filter changes. A clogged filter forces your blower to work against resistance, and that pulls more dust into the system. Change a standard one-inch filter every 60 to 90 days, or more often during fire season. A cleaner system means a faster, simpler cleaning when you do call us.
• Do not fall for the $59 whole-house special. In Pasadena, that price does not exist without a catch. The catch is usually a hard pivot to “sanitization” or “mold treatment” after they open the first vent. Get a written price from a company that stands behind the number, and compare apples to apples.
• Get a free estimate and hold us to it. Call (626) 469-5477 and we will quote your home based on square footage, vent count, and access. The price is written, and it does not move when the technician walks through the door.

Pasadena-Specific Notes That Affect Your Ductwork

Pasadena has a few quirks that make duct cleaning here different from, say, a newer suburb in the Inland Empire.

Aging homes. Pasadena was largely built out by 1960. Craftsman homes in Bungalow Heaven, Spanish Colonials in the Langham area, mid-century ranches in Hastings Ranch – most of them carry ductwork installed decades ago. Galvanized steel ducts from that era have seams that open over time. We see gaps at the plenum connection and separated branch lines all the time. Our Commercial Duct Cleaning technicians flag every gap and quote the sealing work in writing. You decide. No surprises.

Freeway proximity and fire season. Homes closer to the 210 and 134 corridors collect a fine gray dust that works its way through window seals and into return ducts. During fire season, when the winds push particulates across the San Gabriel Valley, even well-sealed homes pull in extra debris. That is not a scare tactic; it is what our filters look like after a bad September. If you live in the western part of Pasadena near the Arroyo, or anywhere downwind of the foothills, plan on checking your filter more often and cleaning your ducts on a 3 to 5 year cycle instead of 5 to 7.

Historic district rules. If your home is in a designated historic district like Bungalow Heaven, any duct-related work that requires roof or exterior access may need design review. We handle attic and interior access points without issue, but you should know what your district requires before anyone touches roof-mounted vents. We are happy to talk through it on the phone before the visit.

How the 365-Day Done Right Promise Works

Every Hollis Air Duct Pasadena job is covered in writing for a full year. If the work fails – meaning a duct we cleaned re-contaminates due to an incomplete job, or a sealed joint opens because we missed it – we come back at no charge. No arguing, no “that’s not covered” dance. The promise is on the written quote and the invoice.

Here is what that covers in plain terms:

• Re-cleaning if the system visibly re-contaminates within 365 days due to a miss on our part. Free second visit, included, not negotiated.
• Re-sealing any access point that fails within the year. We stand behind our mastic and tape work.
• Dryer vent re-clean if the line blocks up within 365 days under normal use. We re-clear it at no charge.

Roy Castellanos signs off on every job. If something is not right, you call (626) 469-5477 and we fix it. That is the Garrison Standard, and it predates most of the other duct cleaning companies currently operating in Pasadena. We have been doing this since 2004.

The Garrison Code: What to Expect When Our Technicians Arrive

We run every job on The Garrison Code. That is not a slogan. It is a set of operating rules every Hollis technician works under, and you can hold us to them:

• Arrive inside the quoted window. The phone call you get has a real time range, and we hit it.
• Write the price before any work starts. The number on the estimate is the number on the invoice.
• Do the job by the book. Every vent, every trunk line, every access point is handled systematically. No skipped vents, no “that one’s hard to reach.”
• Leave the site clean. Drop cloths go down before equipment comes in. Floors get swept. Furniture goes back where it was. You will not find dust trails through the hallway.

Every technician is background-checked and uniformed. You know who is walking into your home before they arrive. If you ever have a question mid-job, the person in your hallway can answer it – and if they cannot, Roy is one phone call away.

Is It Worth Cleaning Ducts That Are Already Clean-Looking?

We get this question from Pasadena homeowners who pull off a vent cover, peek inside, and see what looks like a light dust film. Here is the honest answer: a thin, even dust film is normal and not a problem. What you cannot see from the vent opening is what sits deeper in the trunk line, around the blower, and in the return plenum. That is where the heavy accumulation settles.

If you have lived in the home for five or more years and have never had the ducts cleaned, assume the system is carrying buildup. If you see visible dust blowing from vents when the system kicks on, or if you have unexplained dust settling on furniture within a day or two of cleaning, the ducts are the likely source. A cleaning in that case runs the standard $390 – $760 range and usually takes 3 to 5 hours.

If you just moved in, especially into an older Pasadena home that may have had renovation work, get the ducts cleaned in the first month. Construction dust, drywall particulates, and whatever the previous owner’s pets left behind all sit in the system until someone removes them.

Air Duct Cleaning vs. Replacement: When Repair Beats Cleaning

Sometimes a homeowner calls us expecting a cleaning and the inspection shows the real problem is not dirt – it is damage. Here is how to think about it, with real Pasadena numbers.

A full cleaning runs $390 – $760. If the ducts are intact and the system is operating, that solves the problem. But if the inspection finds collapsed flex duct in the attic, severely separated metal seams, or rust-through on a 60-year-old galvanized trunk line, cleaning will not fix it. The system needs repair or partial replacement.

Duct repair in Pasadena typically runs $200 – $600 for localized fixes like reconnecting a separated branch or replacing a crushed section of flex. Partial duct replacement runs $1,500 – $3,500 depending on how much of the system is compromised. Full duct replacement in a typical Pasadena home runs $4,000 – $9,000.

We will always tell you which one you actually need. If your ducts are dirty but intact, we clean them and that is the end of it. We do not pad a cleaning into a replacement job. Roy Castellanos has been running crews long enough to know that telling the truth keeps the phone ringing, and inventing work is what gives this trade a bad name.

How Often Should You Clean Your Air Ducts in Pasadena?

The honest answer for most Pasadena homes is every 3 to 5 years. Here is how to think through your situation:

• Every 3 years: Homes with pets that shed, homes near the 210 or 134 freeway corridors, homes with residents who have allergies or asthma, homes that had recent renovation work, or homes that run the HVAC system hard through Pasadena’s hot summers.
• Every 5 years: Homes without pets, homes in less dusty parts of the city like the hillside neighborhoods above Colorado Boulevard, and homes where occupants stay on top of filter changes.
• Every 7 years: Same as above, plus a system that uses a high-efficiency media filter or whole-home filtration and shows no visible dust discharge from vents.

If it has been longer than seven years, do not wait for a symptom. The buildup is there. One Pasadena homeowner in Chapman Woods who called us last fall had not cleaned the ducts in 12 years. The system moved air fine, but the blower compartment held an inch of caked dust and the return plenum looked like the inside of a vacuum bag. The cleaning took an extra hour and came in at the high end of the range. An earlier cleaning would have been faster and cheaper.

Air Duct Cleaning Cost vs. Energy Savings: The Pasadena Math

Let us talk about whether a duct cleaning pays for itself. The Energy Department estimates that even minor duct leakage can account for 20 to 30 percent of airflow loss in a typical home. In Pasadena, where August temperatures routinely sit in the 90s and the AC runs daily for three to four months, lost airflow means longer run times and higher electric bills.

Here is the practical version: if your ducts are leaking 20 percent of conditioned air into the attic, and your summer electric bills run $250 – $400 per month for the cooling season, a duct sealing job that cuts that leakage pays for itself within two to three years. Sealing runs $500 – $1,400 as a standalone service, or $35 – $55 per access point during a cleaning. For an older Pasadena home with original ductwork, sealing is the highest-return HVAC investment you can make short of replacing the equipment.

Cleaning alone does not directly lower your electric bill the way sealing does. What cleaning does is preserve airflow, reduce strain on the blower, and keep dust out of your lungs and off your furniture. If your system has not been cleaned in five years, the $390 – $760 is restoring the system to the airflow it was designed for.

Dryer Vent Cleaning: The Add-On We Recommend to Every Pasadena Home

We bring up dryer vents a lot, and here is why: lint is the single most preventable fire hazard in a home, and Pasadena’s older housing stock often has long, convoluted dryer duct runs. A dryer vent in a modern two-story home might run 10 to 15 feet. A dryer vent in a 1940s Pasadena bungalow with the laundry in a converted back porch might run 25 to 30 feet, with three elbows and decades of compacted lint.

Dryer vent cleaning runs $89 – $160 as an add-on when we are already in the home. As a standalone service it runs $130 – $220. The add-on price is the right way to do it – it is already in the range, the equipment is already set up, and the extra time is minimal. If you cannot remember the last time your dryer vent was cleaned, that is the answer: it needs it.

Signs you need it immediately: clothes taking more than one cycle to dry, a burning smell when the dryer runs, the dryer exterior getting hotter than normal, or the vent flap outside not opening when the machine is running. If you see any of those, call (626) 469-5477 and mention it. We can typically get you on the schedule fast, and the cost is inside the range above.

FAQs – Air Duct Cleaning Cost in Pasadena

How much does air duct cleaning cost in Pasadena in 2026?

Air duct cleaning in Pasadena costs $390 – $760 for a standard single-family home in 2026, with most homeowners paying around $525. Condos and smaller homes run $285 – $430, and larger homes above 2,800 square feet run $650 – $1,100. The single biggest driver is vent count. Call (626) 469-5477 for a free written estimate specific to your home.

Is cheaper better when it comes to air duct cleaning?

No, and in Pasadena the cheapest bids are usually the most expensive by the time the job is done. A $59 or $99 whole-house “special” is a loss-leader designed to get a technician into your home, where the price will be renegotiated. Our written price covers the full job from the first vent to the last, and it does not change. If you see a price that seems too low, ask what is included. Then call us and compare.

Can you clean air ducts the same day?

We can often schedule same-week service, and in some cases same-day depending on the schedule. Most full cleanings take 3 to 5 hours on site. If you need it done quickly, call (626) 469-5477 and speak to a live person – our phones are answered 24/7, no voicemail loops.

How much does dryer vent cleaning cost in Pasadena?

Dryer vent cleaning costs $89 – $160 when added to a duct cleaning, or $130 – $220 as a standalone visit. We recommend the add-on for most Pasadena homes, especially older ones with long duct runs where lint builds up fast.

Does duct sealing cost extra during a cleaning?

Yes. Sealing runs $35 – $55 per access point during a cleaning, or $500 – $1,400 as a standalone service. We quote sealing separately and in writing, so the decision is yours. If your home is older and your August electric bills are high, sealing during the cleaning is usually the smartest money you will spend on your HVAC system all year.

How do I know if I need air duct cleaning or something else?

If you see dust blowing from vents when the system starts, if dust settles on furniture within a day or two of cleaning, if your allergies are worse indoors, or if it has been more than five years since the last cleaning, you need a duct cleaning. If airflow is weak in one room or one floor, the problem may be duct damage or a failing blower, and the inspection will tell us. Either way, the estimate is free. Call (626) 469-5477.

Is air duct cleaning worth the money?

For a Pasadena home that has not been cleaned in five or more years, yes. A $390 – $760 cleaning restores airflow, reduces dust circulation, and improves the air you breathe every day. If the inspection also finds duct leakage, sealing during the same visit is the highest-return upgrade you can make short of new equipment. The cost is real and the benefit is measurable.
