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.

HVAC cleaning in North Hills typically costs $380-$740 for a full system and is completed in 4-7 hours.

Why CleanRun Air Duct Cleaning Is North Hills’s Preferred HVAC Cleaning Company
CleanRun has served 52,000+ homes since 2013, and every single one received a written price before a panel came off. That is Haven Standard Clause 1, and it applies in North Hills the same way it applies everywhere we operate. No exceptions.
Our technicians know the difference between a 1954 sheet-metal plenum and a 1997 flex-duct patch job. That matters here. Most North Hills homes were built between 1950 and 1975, and a meaningful share had ductwork disturbed during Northridge earthquake repairs. Dispatched from our Los Angeles office, our crews arrive in North Hills in freshly stocked vans carrying Rotobrush and Abatement Technologies equipment, ready to document the inside of every duct run you own.
Tomas Reyes leads our service team and personally reviews photos from every North Hills job before the final record is released. That’s not theater. It’s how we catch mistakes before you ever see them.
Our HVAC Cleaning Services in North Hills
Evaporator Coil Cleaning
The evaporator coil sits directly in your airstream, and in North Hills it doubles as a filter for everything your ductwork leaks in. We find coil fins packed with a gray paste of skin cells, pet dander, and wildfire ash. A fouled coil drops efficiency by up to 30 percent and forces your compressor to run longer through every 110°F afternoon. We clean it with professional-grade coil solvents, then photograph the result and hand you the picture.
Air Handler Cleaning
Your air handler moves every cubic foot of air in your home, and in North Hills that air carries whatever the attic leaks into it. We open the cabinet, vacuum the blower housing, clean the fan blades, and inspect the motor. What we find in 1960s homes near the Rinaldi corridor is consistent: blower wheels caked with a fine silt that reduces airflow and strains the motor. That silt is attic particulate pulled through unsealed post-earthquake splices. Cleaning the wheel is step one. Sealing the splice is the fix.
Condenser Cleaning
The outdoor condenser unit on your North Hills patio or side yard takes a beating from Valley dust, cottonwood, and direct sun exposure. We clear the fins, check refrigerant levels, and remove debris blocking airflow. A condenser clogged with North Hills particulate makes your whole system work harder at the exact moment summer temperatures peak. We clean it and document the before and after.
Blower Cleaning
A dirty blower wheel is the quiet thief in most North Hills systems. It moves less air, runs hotter, and pushes your energy bill up month after month. We remove the blower assembly, clean it with negative-pressure extraction, and reinstall it with a camera inspection confirming no debris remains downstream. This is included in standard HVAC cleaning, not billed as an add-on.

Common HVAC Cleaning Problems We See in North Hills Homes
- Post-earthquake duct disconnections. The 1994 Northridge quake’s epicenter sat just southwest of North Hills, and many homeowners patched ducts with whatever was available in the months that followed. We routinely find sheet-metal trunk lines spliced into flex duct without mastic or proper fasteners, leaving gaps that pull 140°F attic air directly into your supply runs.
- Degraded flex-duct lining from attic heat. North Hills attics bake to 140°F+ every summer for months. That heat breaks down the inner lining of older flex duct, which sheds fibers that embed in your evaporator coil and blower wheel. This is not a maintenance issue; it’s a material failure.
- Wildfire smoke and ash infiltration. North Hills sits downwind of two active fire corridors: the Chatsworth hills to the west and the Sylmar/Granada Hills ridgeline to the north. Smoke events are near-annual here, and that ash settles inside return ducts and air handlers. Standard filter changes never touch it.
- Crushed or collapsed duct runs. In older North Hills homes, duct runs through tight attic spaces get stepped on, crushed by stored boxes, or simply sag over decades. We find runs with less than 40 percent of their original diameter, choking airflow to entire rooms while the system runs full-time to compensate.
Pricing for HVAC Cleaning in North Hills, CA
A full HVAC cleaning in North Hills runs $380-$740 depending on system size, number of returns, and accessibility of the air handler. Evaporator coil cleaning as a standalone service runs $190-$310. Blower cleaning alone is $140-$240. Full coil treatment with antimicrobial application runs $110-$190. Every price is written before work starts, and the price you sign is the price you pay. That is Haven Standard Clause 1, applied without exception.
What changes the number is not the salesperson’s mood. It’s the square footage of your home, the number of duct runs, and whether we find disconnections that require sealing or section replacement. We’ll put the number in writing and show you the camera photos that justify it. Call (806) 606-6902 for a free estimate delivered the same day.

FAQs - HVAC Cleaning in North Hills
North Hills’s original tract housing used sheet-metal ductwork that has now spent five to seven decades in attics that hit 140°F every summer. The metal itself survives, but every joint, seam, and transition point has been flexing and leaking for decades. Add in post-earthquake flex-duct patches, and the system has been pulling unconditioned attic air for so long that the interior surfaces accumulate debris far faster than a new construction home in Porter Ranch or Arleta. We recommend annual cleaning for most 1950s-1970s North Hills homes.
We find splices where original sheet-metal trunk lines were connected to 1990s-era flex duct using tape or sometimes nothing at all. These connections are chronic debris traps. The camera shows gaps, fallen insulation, and years of accumulated dust packed around the seam. The cleaning removes the debris; the sealing eliminates the source. Call (806) 606-6902 and we’ll show you exactly what we mean in your own ductwork.
Yes, with a qualification. Cleaning removes the ash and particulate that hold smoke odor inside the air handler, coil, and duct runs. What it cannot do is undo odor that has soaked into drywall or carpet. But in North Hills, where the Chatsworth and Sylmar corridors produce near-annual smoke events, the HVAC system is almost always the primary reservoir of that smell. We treat the coil, replace the filter, and run negative-pressure extraction until the camera shows clean surfaces.
The Valley basin traps smog, road dust, and wildfire ash far more aggressively than coastal LA neighborhoods, and North Hills sits in the center of that basin. Your ductwork is accumulating particulate at a faster rate than the same system would in Santa Monica or West LA. For most North Hills homes with older ductwork, annual cleaning is realistic. For homes with post-earthquake splices that have not been sealed, even an annual cleaning is just managing the symptom.
The real fix is sealing or replacing the affected section. Our crew working a 1960s tract home near the Rinaldi corridor found the original sheet-metal trunk line spliced into 1990s flex duct after the Northridge quake, with the connection nearly collapsed and pulling 140°F attic air into a bedroom register. We cut out the crushed section, resealed the transition using mastic and UL-listed tape, then ran a full negative-pressure cleaning with HEPA-filtered air and camera inspection to confirm no debris remained downstream. That’s the difference between cleaning around a problem and fixing it. Call (806) 606-6902 for a written scope on your system.
