Pricing & Estimates
How much does air duct cleaning service cost?
Air duct cleaning in Los Angeles typically runs $350 to $800 for a standard single-family home, and that price depends on the number of vents, the size of the system, and how much debris has built up. A 1,200-square-foot bungalow in Highland Park with 10 vents sits near the low end, while a 3,000-square-foot two-story in Encino with 25 vents and a second HVAC zone pushes toward the top. We write the price down before any work begins, so the number you’re quoted is the number you pay. Call (361) 326-5060 for a free estimate built on your actual system, not a phone guess.
| Service | Typical Los Angeles Range |
|---|---|
| Air duct cleaning (single system, up to 15 vents) | $350 – $800 |
| Additional HVAC zone | $150 – $350 |
| Dryer vent cleaning | $125 – $250 |
| Duct sealing (per system) | $500 – $1,400 |
| HVAC coil and blower cleaning | $200 – $450 |
Do you offer free estimates?
Yes, every estimate is free and comes with a written price before we touch anything. We ask a few questions about your home, your system, and how many vents you have, then give you a range we stand behind. If the job turns out to be simpler than described, the price comes down, not up. There’s no charge to find out what your home needs.
Is it cheaper to repair a duct system or replace it?
Repair and sealing is almost always cheaper than replacement when the ductwork itself is sound and the problem is leaking joints or disconnected runs. Sealing a system runs $500 to $1,400, while full duct replacement in a Los Angeles home often lands between $3,000 and $8,000 depending on attic access and layout. We inspect first, tell you honestly which one you need, and won’t sell you a replacement when a seal will do. Call (361) 326-5060 and we’ll walk you through what we find.
Service & Scheduling
Do you offer emergency air duct cleaning service?
We answer the phone 24 hours a day, 7 days a week, and we schedule urgent calls as fast as our calendar allows. True emergencies with ducts are rare, but they happen: a rodent dies in a return run, a dryer vent backs up and starts smelling of scorched lint, or a renovation fills the system with drywall dust. In those cases we treat it as a priority and get a technician out quickly. Call (361) 326-5060 any hour and a live person will help you sort out what’s urgent and what can wait.
How fast can you respond?
For standard appointments, we typically get to Los Angeles homes within the same week, and same-day slots open up most weeks. When you book, you get a specific arrival window, and our technicians are required to arrive inside it under The Garrison Code. If we’re running late, we call you, not the other way around. Call (361) 326-5060 to check what’s open this week.
What areas do you serve?
We serve Los Angeles and the surrounding metro, including neighborhoods like Sherman Oaks, Silver Lake, Culver City, Pasadena, and the San Fernando Valley communities. Because each Hollis location is independently owned and operated under The Garrison Standard, the crew that shows up at your door is local and accountable to this market. If you’re not sure whether we reach your street, call (361) 326-5060 and we’ll tell you straight.
How long does a duct cleaning appointment take?
A standard single-system home takes about two to three hours, and larger homes with multiple zones can run four hours or more. We don’t rush the job to fit a tight schedule, but we also don’t stretch it out. When we’re done, we show you what came out of the system and leave the site clean. If you need to plan around work or kids, tell us when you book and we’ll work around it.
Licensing & Trust
Are you licensed and insured?
Yes, Hollis Air Duct Cleaning is insured and operates under The Garrison Standard, and our technicians are background-checked and uniformed so you know who’s entering your home. We don’t quote licensing numbers we haven’t published, but we’re happy to confirm our insurance and credentials when you call. Every job is priced in writing, and every job is backed by the 365-Day Done Right Promise. That’s the standard we hold ourselves to, and it’s in writing.
Do you guarantee your work?
Yes, every job is covered by the 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 stated in writing on every invoice, not just promised over the phone. If a sealed joint opens back up or a repair doesn’t hold, you call us and we return. It’s that simple.
Who will show up at my door?
Background-checked, uniformed technicians who work to The Garrison Code, which requires arriving inside the quoted window, pricing in writing before any work, completing the job by the book, and leaving the site clean. You’ll know who’s coming before they arrive, and you’ll see the uniform when they do. If something on site doesn’t match what we quoted, we stop and talk to you first. That discipline is the whole point of how we run.
What payment methods do you accept?
We accept major credit cards, debit cards, and standard payment methods common to home service work, and we’ll confirm options when you book. You get the written price before work starts, so there’s no surprise on the invoice. If you’d like to split payment across a card and another method, ask when you call. We’ll work with what’s practical.
Specific Services
Do you handle air duct cleaning?
Yes, air duct cleaning is our core service, and we use professional-grade equipment including Rotobrush rotary brush systems and Nikro negative-air machines. The negative-air method pulls the entire system under vacuum so loosened debris travels out of the house instead of settling back into your rooms, and the rotary brush scrubs the duct walls where a shop vac can’t reach. This is the same equipment commercial crews use, not a hardware-store rig. For the full picture of how we approach this service across the city, see our Air Duct Cleaning in Los Angeles page.
Do you handle dryer vent cleaning?
Yes, we clean dryer vents, and this is one of the most overlooked fire-safety tasks in a Los Angeles home. Lint builds up in the run and can ignite from the heat of the dryer, and long horizontal runs common in Southern California homes clog faster than short vertical ones. Our dryer vent cleaning typically runs $125 to $250. If your dryer takes two cycles to dry a load or the outside vent flap barely moves, it’s overdue. Call (361) 326-5060 and we’ll take a look.
Do you handle HVAC cleaning?
Yes, we clean HVAC components beyond the ducts, including the evaporator coil and blower assembly where dust and biological growth collect. Coil and blower cleaning typically runs $200 to $450 and matters because a dirty coil makes your system work harder and shortens its life. We pair this with duct cleaning so the whole air path gets handled in one visit. It beats cleaning one half of the system and leaving the other to re-contaminate it.
Do you handle duct repair and sealing?
Yes, we repair and seal ductwork, and sealing typically runs $500 to $1,400 per system depending on how many leaks we find and how accessible the runs are. We use duct sealing mastic, a brush-applied sealant that cures into a flexible, airtight coating over joints, seams, and small holes, which stops the leaks that pull attic dust and unconditioned air into your living space. In older Los Angeles homes with original 1970s and 1980s flex duct, disconnected runs at the plenum are something we see constantly. We inspect first, then give you a written price before any sealing begins.
Is duct cleaning worth it for a newer home?
It depends on the home, and we’ll tell you honestly if you don’t need it. New construction often leaves drywall dust and construction debris inside the ductwork, and that’s a real reason to clean within the first year. In a settled home with no recent work, no pets, and no allergy concerns, the case is weaker. We’d rather turn down a job than sell you one you don’t need. Call (361) 326-5060 and describe your situation, and we’ll give you a straight answer.
Can air duct cleaning help with allergies or dust?
It can help when the ducts are actually dirty, and it won’t when they’re not, so the honest answer is that it depends on what’s in your system. When ducts hold years of dust, pet dander, and pollen, every time the system runs it moves that material through your rooms, and cleaning removes the reservoir. We also install filtration products from Honeywell, Aprilaire, and Guardsman that keep the system cleaner between visits. If allergies are the concern, mention it when you call and we’ll focus our inspection there.
Is air duct cleaning safe for pets and kids in the house?
Yes, it’s safe, and the negative-air setup is what makes it safe: our machines pull the whole system under vacuum while we work, so debris goes into the collection unit instead of into the air your family breathes. You and your pets can stay in the home during the job, though keeping pets out of the immediate work area avoids stress. We leave the site clean when we’re done. That’s part of The Garrison Code, not an extra.
What should I check before hiring any duct cleaning company?
Ask three things: is the price written down before work starts, is the work guaranteed in writing, and will the crew explain what equipment they’ll use. Here’s how we run every job, and what to expect from any company worth hiring:
- Confirm a written price before anyone touches your system, so the number can’t move at the door.
- Confirm the guarantee in writing, including how long it covers and what happens if the work fails.
- Ask which equipment they’ll use. Rotary brush and negative-air machines are the professional standard; a shop vac and a hose are not.
- Confirm who’s coming: background-checked, uniformed technicians you can identify before they arrive.
- Confirm the crew cleans up and shows you the results before leaving.
If a company can’t answer those five, keep calling. If you want a straight answer from us, dial (361) 326-5060 and we’ll walk through each one.
