Air Duct Cleaning Company in Northridge, CA
Air duct cleaning in Northridge runs between $300 and $600 for a typical single-story ranch home, depending on how many returns and registers the system has and how long it has been since the last cleaning. Northridge is different from coastal LA because of what gets into the ducts here: fine dust from the Santa Susana Pass, ash from wildfire seasons, and decades of debris in post-1994 quake rebuilds. You can reach us at (661) 523-0295 for a written, no-hassle quote before any work starts.
Why Northridge Homes Are Different
The housing stock in Northridge sets the conditions for almost every duct job we do here. Most homes are single-story ranch builds from between 1950 and 1980, on slab foundations, with forced-air systems running through the attic. Those attics get hot. The flexible ducts that were standard in that era sit up there all summer long, baking in 100-degree heat, and they degrade differently than the rigid metal ducts you find in newer construction. Flex ducts in Northridge show up with kinks, compression points, and small tears more often than anywhere we work in the Valley.
Then there is the quake factor. A large number of Northridge homes were rebuilt or extensively repaired after 1994, and a lot of that work happened fast. In those rebuilds, we regularly see undersized return lines, overly long flex-duct runs, and ducts that were never properly supported. What that means for homeowners is uneven airflow, rooms that never quite cool down in August, and ducts that fill with debris faster than they should. Add in the Santa Ana winds pushing dust from the foothills and the wildfire ash seasons, and ducts in Northridge load up more heavily than in coastal ZIP codes. A late-fall cleaning here is not a luxury; it is maintenance.
Styles & brands we work with




Our Main Northridge Services
Most homeowners first call us for one of three jobs: a full air duct cleaning, a dryer vent cleaning, or duct sealing after a pressure test shows leaks. Each has its own dedicated Northridge page, linked below.
Air Duct Cleaning in Northridge
Duct cleaning in Northridge means pulling the registers, running a rotary brush through the supply and return lines, and putting the system under negative air with a Nikro machine so the debris goes into the collection unit, not back into the house. In Northridge attics, we almost always find a layer of fine gray dust from the pass and from wildfire ash; in a lot of the post-quake rebuilds, we also find construction debris that was never removed. The job takes a half day for most ranch layouts, and you get before-and-after photos of your own ducts. Full details on Air Duct Cleaning in Northridge.

Dryer Vent Cleaning in Northridge
Older Northridge ranch homes usually have the dryer vent running through the attic or out a side wall, and that run is often longer than code would allow today. Lint builds up in the low spots, especially where the flex line sags between supports. That is not just an airflow problem; it is a fire hazard, and it is the reason we recommend cleaning the dryer vent every year in this climate. We brush the full run and verify airflow at the exterior vent. Details are on Dryer Vent Cleaning in Northridge.

Duct Sealing in Northridge
If some rooms in your Northridge house never get comfortable, the problem is often not the AC unit. It is leaky ducts. Fiberglass flex ducts from the 1960s through 1980s lose their seal at the joints, and in post-quake rebuilds we find metal seams that were taped, not mastic-sealed. We seal with a water-based mastic and, where appropriate, Aeroseal, then re-test static pressure to show you the before and after. The full write-up for what that involves in Northridge homes is on Duct Sealing in Northridge.

AfterPricing for Air Duct Cleaning Company in Northridge, CA
These are the ranges we quote for Northridge homes. The exact number depends on the size of the system, the number of registers and returns, and how long it has been since the last cleaning. No per-vent pricing. One flat price per system, written down before we touch anything.
| Job | Typical range in Northridge |
|---|---|
| Air duct cleaning, single HVAC system | $300 – $600 |
| Air duct cleaning, two-story home | $450 – $800 |
| Dryer vent cleaning | $85 – $150 |
| Duct sealing (mastic sealing of accessible joints) | $250 – $500 |
| Duct sealing with Aeroseal | $800 – $1,800 |
| Blower motor and coil cleaning | $150 – $350 |
| Register and grille replacement (per unit) | $10 – $35 |
| System sanitation / antimicrobial fogging | $150 – $300 |
| Flex duct replacement (per run) | $200 – $500 |
| Return air filter upgrade (media cabinet) | $150 – $400 |
What pushes a Northridge job toward the top of these ranges is usually attic access: a tight crawl space, a steep roof pitch, or flex ducts that have collapsed and have to be re-supported or replaced. If you have post-1994 rebuild ductwork, we will tell you after the inspection, not after the job starts. The price we quote in writing is the price you pay.
