Air Duct Cleaning in Northridge, CA
Air duct cleaning in Northridge typically costs $350-$550 for a standard residential system up to 12 vents, with full system cleaning and video inspection running $550-$850. Most jobs are completed in a single visit by our background-checked, uniformed technicians, and every homeowner receives camera-verified before-and-after documentation. Northridge’s unique combination of post-WWII ranch homes and 1994 earthquake-rebuilt properties creates duct conditions you won’t find in neighboring Valley cities, which is why we tailor our approach to what your specific home demands. Call (855) 401-6006 to speak with a live person and get your upfront price before we lift a single tool.
Why Northridge Homes Are Different
Northridge sits on the inland San Fernando Valley floor where summer temperatures routinely top 105°F and often push 110°F - well above what coastal Los Angeles neighborhoods experience. From June through September, residential HVAC systems here run almost continuously, pulling significantly more particulates, dust, and allergens through duct systems each season than moderate-climate homes.
The housing stock tells a second story. Northridge is the namesake of the 1994 Northridge earthquake, and ductwork throughout the neighborhood - especially in the 91324 and 91325 ZIP codes - was displaced, cracked, or hastily reconnected during the massive post-quake rebuilding rush. Thirty years later, those mid-1990s flex-duct installations are now sagging, kinked, and collecting debris at disconnected joints. Technicians working along streets like Reseda Boulevard and Zelzah Avenue frequently find flex duct installed quickly by multiple contractors in 1994-1995 with mismatched fittings and unsealed register boots.
Air Duct Cleaning in Northridge
Our Air Duct Cleaning service addresses both layers of Northridge housing: the original post-WWII ranches with decades of accumulated buildup, and the 1994-1996 rebuilds with flex-duct systems now reaching the end of their functional life. We use Rotobrush contact cleaning and negative-air methods to dislodge debris from every branch line, then verify with camera inspection before we leave.
Residential Duct Cleaning
For homes near Northridge’s older tracts off Tampa Avenue or the rebuilt properties along Reseda Boulevard, we tailor our approach to your specific duct material and condition. The post-earthquake rebuilds throughout 91324 and 91325 are particularly susceptible to separated register boots from 1994-1995 that have degraded under decades of thermal expansion, pulling insulation fibers and unconditioned attic air directly into supply lines. A standard residential system with up to 12 vents runs $350-$550.
Supply Duct Cleaning
Supply ducts push conditioned air into your living spaces, but in Northridge they’re often the path for attic debris to enter your home. We clean and seal these pathways, restoring proper airflow and reducing the particulate load your family breathes. Return or supply duct cleaning alone typically falls between $200-$350.
How does Northridge’s 1994 earthquake affect my air ducts today?
The post-earthquake rebuilding rush installed thousands of flex-duct systems with mismatched fittings and unsealed register boots that have now degraded for thirty years. These hastily connected joints have separated under thermal cycling, pulling unconditioned attic air and insulation fibers into your living spaces. We find this damage routinely in homes rebuilt 1994-1996, especially in the 91324 and 91325 ZIP codes. Call (855) 401-6006 for a video inspection that maps these problems exactly.
Dryer Vent Cleaning in Northridge
Dryer vent cleaning in Northridge typically runs $149-$189 for standard single-story homes with direct exterior wall vents, with attic-run or roof-cap jobs at $189-$249. We know the difference between a ranch home on Zelzah Avenue with its original 1960s venting and a rebuilt property off Reseda Boulevard with the foil-flex installations that went in after the ’94 quake.
Dryer Vent Inspection & Cleaning
We start every Northridge job with a camera inspection of the full vent run, from the back of your dryer to the exterior cap. In the 91324 and 91325 ZIP codes, we’re specifically looking for crushed foil vents, kinked flex duct, and unsealed joints that trace back to the post-earthquake rebuild era. Standard cleaning for a direct exterior wall vent runs $149-$189, while attic-run or roof-cap access moves the job to $189-$249.
Vent Rerouting & Replacement
Some Northridge homes, especially slab-on-grade ranches common south of Devonshire, have dryer vents that run 25 feet or more through the attic to a roof cap. Long runs kill airflow and create sag points where lint collects. We can reroute to an exterior wall cap where feasible, shortening the run and improving performance, with vent rerouting typically at $249-$389 and full replacement of crushed foil with smooth-wall aluminum at $199-$289.
How does the 1994 Northridge earthquake affect my dryer vent today?
Many Northridge homes, particularly in 91324 and 91325, received semi-rigid or foil-style dryer vents during the 1994-1996 post-earthquake rebuilds that were never intended to last thirty years. These vents are now prone to crushing, kinking, and lint trapping due to their non-UL-listed construction and age. If your home was built or rebuilt during that period, we inspect specifically for this legacy material and replace it with code-compliant smooth-wall aluminum. Call (855) 401-6006 to schedule.
HVAC Cleaning in Northridge
HVAC cleaning in Northridge typically runs $280-$650 for full system service, with individual components priced separately depending on what your system needs. The Valley’s extreme heat and Santa Ana dust loads mean your evaporator coil, blower, and condenser work harder here than in coastal LA, and they collect debris faster too.
Evaporator Coil & Blower Cleaning
The evaporator coil is where your system works hardest in Northridge heat, and where Santa Ana dust does its worst damage. When coils clog with Valley particulates, airflow drops, ice forms, and your compressor strains. We use professional-grade foaming cleaners and low-pressure rinses that clear the fins without bending them. A typical evaporator coil cleaning runs $180-$340, while blower cleaning - essential when filters load fast and bypass happens - falls between $160-$290.
Condenser & Full System Cleaning
Your outdoor condenser faces 110°F days and Santa Ana grit. The aluminum fins clog with dust, cottonwood, and particulate from Valley construction, choking heat rejection and spiking your electric bill. We straighten fins, clean coils with foaming agent, and clear the condensate drain. Condenser cleaning typically costs $140-$260, and full system HVAC cleaning runs $280-$650 depending on component count and accessibility.
How often should I schedule HVAC cleaning in Northridge given the Santa Ana winds?
Most Northridge homes need full HVAC cleaning every two to three years, but homes exposed to frequent Santa Ana events or near construction zones should consider annual coil and blower service. The Valley’s dust load is measurably higher than coastal LA, and post-quake flex duct gaps amplify the problem by pulling unfiltered attic air. We offer $89 Seasonal Tune-Ups to catch buildup before it becomes a system failure. Call (855) 401-6006.
Duct Repair & Sealing in Northridge
Most duct repair jobs in Northridge run $180-$650 and are finished in a single visit. We cover all Northridge ZIP codes - 91327, 91328, 91329, 91330 - plus the 91324 and 91325 areas where post-earthquake flex duct is now hitting its 30-year failure point. Every repair starts with camera inspection so we can show you exactly what needs attention.
Flex Duct Repair & Replacement
Flex duct is the weak point in most Northridge homes built or rebuilt between 1994 and 1996. The inner plastic liner degrades, the insulation compresses, and the wire helix sags until airflow is choked to a trickle. On a recent job near Zelzah Avenue, we found a ranch-style home with sagging flex duct from the mid-90s rebuild - the inner liner had collapsed, and unsealed register boots were pulling hot attic air into every room. Flex duct repair or replacement per run typically runs $220-$480.
Mastic Sealing & Air Leak Repair
Duct tape fails. Mastic doesn’t. We apply professional-grade mastic sealant to every joint, seam, and register boot connection, creating a permanent bond that withstands the thermal expansion and contraction of Northridge’s extreme temperature swings. A typical mastic sealing job for an average Northridge home runs $280-$520, while localized air leak repair for one or two joints falls between $180-$340. Whole-system sealing on larger homes runs $450-$850.
Does the 1994 Northridge earthquake still affect ductwork in my home?
Yes, if your home was rebuilt or heavily renovated between 1994 and 1996, the flex duct installed during that rushed period is now reaching its failure point. The 91324 and 91325 ZIP codes have thousands of these installations, and we find collapsed liners, sagging runs, and unsealed joints on a weekly basis. Call (855) 401-6006 and we’ll camera-inspect your system to see if you’re affected - estimates are free.
Air Quality & Sanitizing in Northridge
Northridge’s constant summer HVAC operation pulls dust, allergens, and whatever’s hiding in your ducts through every room of your house. Our Air Quality & Sanitizing service targets the sources that standard cleaning alone won’t fix: mold from condensation in sagging flex duct, bacteria riding Santa Ana dust particles, and persistent odors from decades of trapped debris.
Mold Treatment & Bacteria Sanitizing
Mold in Northridge ducts usually traces back to condensation from overworked AC units running 16 hours a day through July and August, and moisture trapped in sagging post-earthquake flex duct where low spots collect condensation. We treat active mold with EPA-registered products from Abatement Technologies, then seal the source so it doesn’t return. Targeted mold treatment runs $350-$620, while whole-home duct sanitizing for bacteria and odor typically costs $280-$450.
Filtration Upgrades & UV Installation
Standard 1-inch filters don’t stop the fine particulates that carry bacterial loads into your living space during Santa Ana wind events. We fog duct systems with hospital-grade sanitizer and install higher-efficiency filtration where the HVAC design allows. For families with respiratory sensitivity, we specify Aprilaire whole-home media cleaners. UV-C light installation runs $380-$550, and whole-home media cleaner installation typically falls between $680-$950.
Why is my Northridge home’s air still dusty after a standard filter change?
Your ducts are likely leaking. In Northridge’s 91324 and 91325 ZIP codes, post-1994 earthquake rebuild flex duct was installed with unsealed register boots and mismatched fittings that pull attic dust directly into your supply air, bypassing the filter entirely. We camera-inspect to locate the leaks, seal them with mastic, and upgrade filtration to match your actual particle load. Call (855) 401-6006 for a free estimate.

What Northridge Customers Say
"The job was done well and the house smells better. There was some dust knocked loose around a couple of the registers that I had to wipe down afterward."
- Jodi Ackerman"Booked online at nine at night, got a confirmation, a reminder, and a call when they were fifteen minutes out."
- Renee Fletcher"They ran a negative air machine on the whole system rather than the shop vac on a stick that the cheap outfit uses. Showed me the before and after photos from inside the trunk line and it was genuinely disgusting."
