Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFast, Reliable HVAC Cleaning Across Northridge
HVAC cleaning in Northridge runs $380-$650 for a typical single-family home with one furnace and one AC coil, and most jobs take four to six hours with two technicians. That’s the number we give you before a panel comes off, in writing, under Haven Standard Clause 1. We serve Northridge from Reseda Boulevard to Zelzah Avenue, and from Lassen Street up to the 118, with crews who know exactly what’s hiding in the attic duct runs of 1960s-era Valley ranchers. Call (806) 606-6902 and you’ll get a live person, a specific window, and a technician identified by name before arrival.
Northridge is the only San Fernando Valley community where the January 1994 magnitude-6.7 earthquake severed supply plenum connections in thousands of attics. The post-quake rebuild was fast, and a lot of it was done with duct tape instead of mastic. That tape is now 30 years old, dried, and peeling. The joints it was meant to hold together are open. And those open joints pull fiberglass insulation directly into the airstream. We see this pattern in Northridge more than anywhere else in the Valley. It’s not a generic dust problem. It’s a specific failure mode with a specific fix, and you can’t price it correctly until someone looks inside with a camera.
Why CleanRun Air Duct Cleaning Is Northridge’s Preferred HVAC Cleaning Company
We’ve cleaned HVAC systems in homes off Devonshire Street, through the Northridge West neighborhood, and across the CSUN-adjacent blocks where mid-century ranchers still run their original duct work. The homes change. The failure patterns don’t.
Every job starts the same way: a written price, delivered before any work begins. Not a phone estimate, not a ballpark. A number. Our HVAC Cleaning team photographs the inside of every duct run before and after, so you don’t have to trust a verbal summary. You see the before. You see the after. That photo record is part of the standard job file, not an upsell.
Tomas Reyes, who runs our crew operations, has walked more Northridge attics than he can count. His technicians are background-checked and uniformed, and they work under the H.A.V.E.N. Standard. Clause 3 is Verified Crews, and it means exactly that. When a technician arrives at a Northridge home, they identify themselves by name before they step inside. No surprise crews, no mystery sub-contractors.
Since 2013, CleanRun has served 52,000+ homes. Every one of them got a written price before work started, and a documented photo record when the crew left. The 365-Day Done Right Promise backs every job in writing. If it’s not right, we make it right. That’s not a phrase on a brochure. It’s a line in the written guarantee we hand you.
Our HVAC Cleaning Services in Northridge
Northridge homes run their AC hard from June through October, and that means the coil, blower, and air handler all carry more load than they would in a coastal zip code. Here’s what we do when we open a system in this part of the Valley.
Evaporator Coil Cleaning
The evaporator coil sits inside the air handler and does the actual cooling work. In Northridge, a typical coil in a 1960s rancher will show a gray film of fine Valley dust after two or three years, even in a clean house. Santa Ana events load it faster. We pull the coil, apply a professional-grade cleaner, and flush it. A coil cleaning in Northridge typically runs $180-$320 when done as part of a full HVAC cleaning. On its own, it’s $200-$350. A dirty coil costs you efficiency every day it runs, and in a Valley summer, that’s real money.
Blower Cleaning
The blower wheel moves air across the coil and through the house. In Northridge, we routinely find blower wheels caked with a paste of fine dust and cooking oils that have re-circulated through the return side for years. The wheel loses balance, the motor works harder, and you can hear it. We remove the blower assembly, clean each fin, and reinstall. Blower cleaning in Northridge runs $150-$280. It’s the kind of work that changes how the system sounds on day one.
Condenser Cleaning
The condenser is the outdoor unit, usually on the side of the house or in a side yard. Northridge yards are dry, and the condenser pulls in dirt, leaf debris, and plenty of Santa Ana dust. We clean the fins, straighten what’s bent, and check the refrigerant levels. A condenser cleaning here runs $130-$250. It’s fast work, but it matters. A clogged condenser in 105°F heat is the difference between the system keeping up and falling behind.
Air Handler Cleaning
The air handler is the heart of the system, and in Northridge it’s often in a closet or garage from the original build, with decades of accumulated debris inside. We clean the cabinet, the interior surfaces, the drain pan, and the blower assembly. Air handler cleaning in Northridge runs $220-$400 depending on access and condition. This is the service that often uncovers the earthquake-related damage we described above: separated plenums, open joints, insulation getting pulled into the airstream.

BeforeAfterTrusted Brands We Service in Northridge
Northridge homes run a mix of equipment, much of it installed during the post-1994 rebuild wave and a good portion of it original to 1950s and 1960s construction. We service and clean systems from every major brand, and we show up with professional-grade tools that any homeowner can research independently: Rotobrush extraction systems, Nikro air scrubbers, Honeywell filtration, and Guardsman sanitizing equipment. We don’t use shop-vacs. We don’t use fog machines that cover everything in a fine mist of nothing. We use equipment built for source removal and negative-pressure extraction, and we name it on the page so you can verify it before we ever arrive.
Common HVAC Cleaning Problems We See in Northridge Homes
Here’s what actually shows up when we open a Northridge system. If any of this sounds familiar, the fix is usually more specific than just “cleaning the ducts.”
- Fiberglass fibers around supply registers: In Northridge homes with 1994-1996 post-quake repairs, we frequently find insulation being drawn through open duct joints into the supply side. You change the filter, and the fibers show up anyway. That’s a duct integrity problem, not a filter problem.
- Crushed flex duct in crawlspaces: 1950s-era Northridge tract homes often have crawlspace duct runs that settled after the earthquake. A crushed run cuts airflow silently, and your system works harder while the rooms at the end of the run never cool properly.
- Dried-out duct tape from 1994-1996 repairs: The rebuild after the Northridge earthquake moved fast, and duct tape was the quick fix in thousands of attics. That tape is now past its service life. Joints are open, and attic air is entering the system downstream of the filter.
- Santa Ana ash loading coils and blower wheels: Northridge sits directly in the path of Santa Ana winds funneling dust and ash from the Santa Susana and Simi Hills. That particulate settles on coils and blower wheels, reducing the real-world efficiency of your filter, even when the house is buttoned up.
On a 1960s rancher off Devonshire Street, our crew opened the attic access and found the return plenum separated at the elbow, with fiberglass batt from the 1994 rebuild being sucked into the air handler. We performed source removal under negative pressure, replaced the collapsed flex run with R-8 insulated duct, and mastic-sealed every joint. Then we confirmed with camera inspection that both sides met NADCA standards. That’s what a real cleaning looks like in this neighborhood. It’s not just vacuuming. Sometimes it’s rebuilding the connection.
Pricing for HVAC Cleaning in Northridge, CA
- Full HVAC cleaning (one furnace, one AC coil, all accessible duct runs): $380-$650
- Evaporator coil cleaning (standalone): $200-$350
- Blower cleaning: $150-$280
- Condenser cleaning: $130-$250
- Air handler cleaning: $220-$400
- Coil treatment after cleaning: $60-$120

What moves the price in Northridge is the age of the duct work and what the camera finds. A clean 1990s system with intact mastic seals is on the lower end. A 1960s rancher with earthquake-damaged plenums and open joints runs higher, because the fix is structural, not cosmetic. We give you one written number before we start, and that number doesn’t change after the panels come off. If you have a competitor’s written quote, bring it. We’ll put our number next to it in writing, and you decide. That’s the Free Second Opinion, and it costs you nothing. Call (806) 606-6902.

FAQs - HVAC Cleaning in Northridge
Why does my Northridge home have fiberglass fibers around the supply registers even after changing the filter?
Because the fibers aren’t coming through the filter. In post-1994 Northridge homes, open duct joints in the attic let fiberglass insulation enter the airstream downstream of the filter. The filter can’t catch what never passes through it. The fix is sealing the joints with mastic, not just replacing the filter more often. Call (806) 606-6902 and we’ll camera-inspect the runs to find the open joints.
How do I know if my Northridge ductwork was improperly repaired after the 1994 earthquake?
Look for three things. Silver duct tape at elbow connections is the big one, since mastic is the correct sealant and tape dries out. If you see fibers around registers, or dust reappears within days of cleaning, you likely have open joints. And if some rooms never cool properly, the airflow problem is often a crushed or disconnected run in the attic or crawlspace. A camera inspection settles it.
Does HVAC cleaning in Northridge include sealing the ductwork or just removing dust?
Our standard HVAC cleaning in Northridge includes source removal under negative pressure and a full camera inspection. Sealing open joints with mastic is a separate scope we quote in writing when the camera finds failures. Many Northridge homes need both. We’ll show you the photos that document the open joints, and you decide what to address. No pressure, just evidence.
Can Santa Ana winds contaminate my Northridge ducts even if the house is closed up?
Yes. Santa Ana wind events push fine dust and wildfire ash across the Valley floor, and that particulate finds its way into any duct leak. If your return side has open joints in the attic, the system is pulling in attic air, and the attic air during a Santa Ana is loaded with dust. A sealed system with a clean filter handles it. A leaky system doesn’t.
What is the difference between an HVAC cleaning and an air handler cleaning for Northridge homes?
An air handler cleaning covers the interior of the air handler cabinet, the blower assembly, the coil, and the drain pan. A full HVAC cleaning includes all of that plus every accessible duct run from the supply plenum to the registers. In Northridge homes with earthquake-damaged duct work, the full cleaning is usually the right call, because the duct runs are where the contamination is actually entering the system. We quote both, in writing, before anything starts.
Call (806) 606-6902 for a written estimate and a real person on the line. Every job includes a documented photo record, a written price before work starts, and the 365-Day Done Right Promise.
