AfterHow Much Does HVAC Cleaning Cost in North Hollywood?
HVAC cleaning in North Hollywood typically costs between $350 and $900 for a full house, with most single-family homes landing near $500 to $650. A single dryer vent runs $120 to $200, and duct repair for compromised runs ranges from $250 to $900 depending on how much ductwork needs attention. The written estimate sets the final price, and it’s free.
What separates one quote from another isn’t usually the number of vents. It’s the equipment on the truck. A shop vac and a spinning brush will look busy for an hour. A Rotobrush contact-cleaning system paired with a Nikro HEPA vacuum actually dislodges debris from the duct wall and captures it down to 0.3 microns instead of blowing it back into the room. That’s the difference between cleaning and the appearance of cleaning, and it’s worth understanding before you compare bids.
Here’s how pricing breaks down in our market, what pushes a job up or down, and how to read a quote without a sales pitch attached.

HVAC Cleaning Cost Breakdown (2026)
These are typical ranges for North Hollywood and the surrounding Valley. Every home is different, and the written estimate is what sets the price.
| Service | Typical Range | What It Covers |
|---|---|---|
| Full-home air duct cleaning | $350 – $900 | All supply and return runs, registers, trunk lines, and the air handler cabinet |
| Single-vent or low-count cleaning | $200 – $350 | Small homes, condos, or jobs with six or fewer vents |
| Dryer vent cleaning | $120 – $200 | Full run from the dryer to the exterior termination, with lint removal |
| Air duct repair (per compromised run) | $250 – $900 | Reconnecting separated joints, sealing leaks, replacing damaged flex or rigid sections |
| Dryer vent repair or re-route | $200 – $600 | Fixing crushed or disconnected venting, correcting improper terminations |
| Post-renovation cleaning | $500 – $1,100 | Heavy drywall dust and construction debris removal, often with containment |
What drives the range: the number of vents and returns, how accessible the ductwork is, the age and condition of the system, and how much contamination is present. A newer home with eight vents and clean flex duct sits at the low end. A 1950s Valley ranch with twenty vents, original rigid duct, and a recent remodel sits at the high end. Post-renovation jobs climb higher because drywall dust is fine, stubborn, and coats everything inside the system.
A duct repair line item only appears when there’s actually something to fix, like a separated joint in the attic or a crushed run behind a cabinet. We don’t pad a quote with repair work you don’t need, and we don’t clean around a problem and call it done. If a run is disconnected and pulling attic air into the system, cleaning it first would be a waste of your money.
Dryer vent cleaning is priced separately because it’s a separate system entirely, and it’s the one most homeowners skip. A clogged dryer vent is a fire risk. We treat it like one.
What Affects HVAC Cleaning Pricing in North Hollywood
- Number of vents and returns. This is the single biggest driver. A one-bedroom condo might have five supply vents and one return. A 1960s ranch in the Valley could have twenty or more. Each vent takes time to properly contact-clean and HEPA-vacuum.
- System accessibility. Ductwork buried in tight attic space, run under a low crawl, or packed alongside plumbing is slower to work. North Hollywood has plenty of homes where the air handler sits in a closet or a tight attic corner, and that access time shows up in the quote.
- Contamination level. A system that’s never been cleaned in thirty years, or one coming out of a remodel, takes more passes. Drywall dust from a kitchen or bathroom renovation is the most common reason a job jumps into the upper range.
- Duct type. Rigid metal duct cleans differently than flex duct, and older rigid systems sometimes have loose insulation inside that requires careful handling. Flex runs that have collapsed or torn often need repair before cleaning makes sense.
- Whether repair is needed. A separated joint or a crushed run means the system is pulling unfiltered air from the attic, garage, or crawlspace. Cleaning a compromised system without fixing it first just re-contaminates the house.
- Dryer vent length and routing. A short, straight vent is quick. A long run with multiple elbows, a crushed section behind the dryer, or a termination that’s hard to reach takes longer and prices accordingly.
Why North Hollywood Homes Ask for This Work
Most of the calls we get from North Hollywood start with a reason. Someone in the house has allergies that won’t quit. A renovation just wrapped and the dust is everywhere. A new HVAC system went in and the installer flagged the old ductwork. Or an inspection turned up something that needs answering.
The Valley’s housing stock makes some of this predictable. A lot of North Hollywood homes were built in the postwar decades, and the ductwork in them has had a long time to accumulate debris, collect dust at the joints, and in some cases come apart at the seams. Attic heat is hard on flex duct, and a run that’s been baking up there for years can sag, tear, or pull loose from a collar. That’s not a cleaning problem. It’s a repair problem that happens to show up as a dust problem.
Renovation is the other big trigger. Drywall dust is relentless. It gets pulled into the return, coats the inside of the trunk line, and shows up on every surface in the house for months. A proper post-renovation cleaning with Abatement Technologies filtration equipment running as containment keeps that dust from spreading through the home while the work is happening. That’s the standard restoration and abatement crews work to, and it’s the standard we bring into a house.
If you’re new to the neighborhood and figuring out who to call, Onyx Duct Cleaning is a focused indoor-air-quality specialist. We do three things: air duct cleaning, dryer vent cleaning, and air duct repair. That’s it. That focus is the reason we can show you the system rather than just hand you an invoice.
What Should a Proper HVAC Cleaning Include?
Before you compare prices, know what you’re comparing. A legitimate cleaning includes source removal: the debris gets physically dislodged from the duct wall and captured, not just loosened. Here’s what the process looks like done right.
- Containment and negative pressure. A HEPA vacuum pulls the system into negative pressure so nothing escapes into the living space while work is happening.
- Contact cleaning on every run. Rotobrush contact-cleaning systems put a rotating brush against the duct wall. That’s what dislodges the debris that’s stuck, not just the loose dust.
- HEPA capture. Nikro HEPA vacuum systems capture particles down to 0.3 microns, so what comes off the wall gets contained rather than recirculated.
- Register and vent cleaning. Supply and return covers get cleaned, along with the boots behind them.
- Air handler cabinet. The cabinet, blower area, and coil face get cleaned where accessible. We don’t service the mechanical components, but we clean the housing they sit in.
- Before-and-after visibility. We show you what came out and what the system looks like when we’re done. You should be able to see the difference, not just take our word for it.
If a quote is dramatically lower than everything else you’ve received, ask what equipment will be on site. If the answer is a shop vac and a brush, you’re paying for the appearance of cleaning. Contractor-grade equipment, residential pricing: that’s the balance worth looking for.
How to Save on HVAC Cleaning
There’s no magic discount, but there are real ways to keep the number down.
- Bundle the dryer vent with duct cleaning. The dryer vent is often the cheapest line item and the highest value. Doing both in one visit cuts the trip and the setup time, and the combined quote usually reflects that.
- Address repair before it gets expensive. A separated joint caught early is a small repair. A run that’s been pulling attic air into the system for years can mean contamination spread through the whole house and a much bigger cleaning job. Duct repair priced at $250-$900 today can save a much larger bill later.
- Clean after the renovation, not before. If you’re planning a kitchen or bathroom remodel, schedule the cleaning for after the dust settles. Cleaning first and then remodeling means paying twice.
- Get the estimate in writing before work starts. A free estimate tells you exactly what’s included. Ask whether the air handler cabinet, registers, and all returns are covered, and whether the price changes if repair is needed.
- Change your filters on schedule. A clean filter keeps debris from reaching the system in the first place. It won’t replace a cleaning, but it stretches the time between them.
- Ask about filtration upgrades. If you’re already having the system cleaned, that’s the logical time to talk about a better filter setup. We work with Honeywell and Aprilaire systems and understand how whole-home filtration fits into the ductwork. A filter upgrade is a separate conversation from the cleaning, but the visit is the right moment to have it.

Is It Cheaper to Repair or Replace Ductwork?
Repair is almost always cheaper than replacement. Repairing a separated joint or sealing a leak typically runs $250-$900, while a full duct replacement is a much larger project. Most homes don’t need replacement, and the honest answer is usually that repair gets the system working again for a fraction of the cost. We do duct repair as a standalone service, which means we can fix the root cause rather than clean around it.
FAQs – HVAC Cleaning Cost
How much does HVAC cleaning cost in North Hollywood?
Full-home HVAC cleaning in North Hollywood typically runs $350 to $900, with most single-family homes landing between $500 and $650. Small condos and homes with six or fewer vents can fall into the $200-$350 range. The written estimate sets the final price, and it’s free. Call (833) 589-9715 for an exact quote.
How much does dryer vent cleaning cost?
Dryer vent cleaning typically costs $120 to $200 in North Hollywood, depending on the length of the run and how accessible the termination is. A clogged vent is a fire risk, so it’s worth pricing even if the rest of the system looks fine. Call (833) 589-9715 for a free estimate on both.
Can you fix damaged ductwork, or do you only clean it?
We fix it. Air duct repair is a standalone service at Onyx, priced at $250-$900 per compromised run. That covers reconnecting separated joints, sealing leaks, and replacing damaged flex or rigid sections. Cleaning a disconnected run without fixing it would just re-contaminate the house. Call (833) 589-9715 to have the system assessed.
Why is my quote higher than a competitor’s?
The difference is almost always equipment and scope. A $200 quote usually means a shop vac and a brush, not a Rotobrush contact-cleaning system and Nikro HEPA vacuum. Ask what equipment will be on site and whether the air handler cabinet, all returns, and register boots are included. Call (833) 589-9715 and we’ll walk you through exactly what our estimate covers.
Can you come today?
Same-day service is often available, and the best way to find out is a call. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday. Call (833) 589-9715 and we’ll book you into the next opening.
Does North Hollywood’s climate affect how often ducts need cleaning?
It plays a role. Valley heat is hard on flex duct, and a run that’s been baking in an attic for years can sag or pull loose at the joints. Homes here also tend to run the system hard through the warmer months, which moves more dust through the ductwork. Most homes benefit from a cleaning every few years, sooner after a renovation or if anyone in the house has allergies. Call (833) 589-9715 to talk through your specific system.
What Happens When You Call
You tell us what’s going on. Allergies, a renovation, a new HVAC install, an inspection flag, a dryer that’s taking two cycles to dry a load. We ask about the house, the number of vents, and whether there’s any known duct damage. Then we schedule a time for a free estimate, and you get a written number before any work starts.
When we’re on site, we show you the system. We’ll point out the air handler, the trunk line, the returns, and any run that looks compromised. If you have a dryer vent that’s crushed behind the dryer or terminating somewhere it shouldn’t, we’ll show you that too. The estimate covers the full picture, cleaning, dryer vent, and any repair work that makes sense, so there are no surprises.

What Our Customers Say
"Did the dryer vent while they were here for a small add on price. The dryer now finishes a load in one cycle instead of two."
- Dustin Bennett"Fair price and thorough work. They ran about an hour and a half past the estimated finish time, so don't schedule anything tight after."
- Emily Wong"Found a disconnected run in the crawlspace while they were in there and told me about it rather than cleaning around it."
