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 San Fernando
HVAC cleaning in San Fernando, CA typically runs $380-$720 for a full system clean that includes the evaporator coil, blower assembly, and air handler. Most jobs take four to six hours and are scheduled within a week, not same-day. That range reflects something specific about this city: homes here were built between 1945 and 1970, when central air meant a retrofit into houses designed for swamp coolers. Those systems have more gaps, more patchwork flex duct, and more places for contamination to hide than anything in a newer Granada Hills build. The clean has to account for that.
CleanRun Air Duct Cleaning has worked San Fernando’s older blocks long enough to know what we’ll find before the camera goes in. If you want a documented record of exactly what came out of your ducts and what was sealed, call (806) 606-6902. A written price comes before any work, every time.
Why CleanRun Air Duct Cleaning Is San Fernando’s Preferred HVAC Cleaning Company
We don’t ask San Fernando homeowners to take our word for anything. Every job includes a written price delivered before a single panel comes off, and a photo record of the inside of every duct run, before and after, as a standard deliverable. That’s Haven Standard Clause 1: no-hassle upfront pricing. It’s why homeowners who would never book a $79 coupon crew call us instead.
Tomas Reyes leads our team, and the crews he sends to San Fernando are background-checked, uniformed, and identified by name before they arrive. Their equipment includes Rotobrush and Nikro negative-pressure systems with HEPA filtration, plus camera inspection rigs we don’t skip on retrofit houses. On a 1952 rambler off Maclay Ave, our techs found the supply and return ducts caked with gritty, oily residue, diesel ultrafines from the I-5/SR-14 corridor, and three runs partially crushed in a 140°F attic. After source removal with agitation tools and HEPA filtration under negative pressure, we sealed the leaking junctions and replaced the collapsed sections. The homeowner kept every photo. That’s the record we leave on every job.
Our HVAC Cleaning Services in San Fernando
Evaporator Coil Cleaning
In San Fernando, the evaporator coil works harder than in the coastal basin. Systems run near-continuously from June through September, which means the coil builds a crust faster. A typical evaporator coil cleaning here runs $180-$340. We pull the coil, photograph the buildup, clean it with professional-grade coil treatment, and photograph it again before reinstalling.
Air Handler Cleaning
This is where the freeway residue concentrates. Air handlers in San Fernando’s 1940s-1960s homes pull return air through leaky retrofit ductwork, and the blower housing and insulation collect the particulates that slip through. Air handler cleaning in this city runs $150-$280, and it’s not optional once the motor assembly has been coated in the residue we find east of Brand.
Blower Cleaning
Blower wheels in older San Fernando systems can lose 20-30% of their airflow from caked debris on the fins. On retrofit jobs, the blower often runs against crushed or restricted ducts, compounding the problem. Blower cleaning runs $120-$220 and typically adds a measurable airflow improvement we document in the photo record.
Condenser Cleaning
The outdoor condenser in San Fernando sits in a bowl that collects Valley dust, pollen, and diesel particulate. A condenser clean runs $110-$190 and includes fin straightening where needed, coil wash, and a documented before-and-after. It’s the part of the system homeowners can see, but the inside of the coil is what matters, and that’s where our camera goes.

BeforeAfterTrusted Brands We Service in San Fernando
San Fernando’s housing stock came before modern efficiency standards, so we see a mixed bag: Honeywell controls, Aprilaire filtration add-ons, and a lot of Guardsman components in older service panels. We stock common replacement parts for these brands and can usually source anything unusual from our metro parts network within a day. Our techs are trained on each system type, and the photo record we provide includes the nameplate data so you can verify what’s in your system before you agree to any price.
Common HVAC Cleaning Problems We See in San Fernando Homes
- Diesel ultrafine residue. Homes near the I-5 and SR-14 corridor pull in freeway particulate that bakes onto hot duct walls in July and August. Standard negative-pressure extraction alone won’t remove it; agitation tools are required, and you should ask any company you call whether they use them.
- Crushed attic runs. San Fernando attics hit 140°F in summer, and flex duct from retrofit installs degrades and collapses. During a cleaning, our camera routinely finds runs that are 40-60% crushed. Cleaning those runs without repairing them wastes the job.
- Non-standard fittings at every junction. Central air added after 1945 was rarely built to tight tolerances. Gaps at plenum connections pull attic air and ultrafines into the HVAC system continuously. If a crew finishes without sealing, the contamination returns within weeks.
- Baked-on coil crust. Valley heat cycles enormous air volumes through San Fernando evaporator coils, and the oily freeway residue creates a baked layer that standard coil spray won’t touch. Proper coil treatment and mechanical cleaning are required.
Pricing for HVAC Cleaning in San Fernando, CA
A full HVAC cleaning in San Fernando typically runs $380-$720. The range reflects system condition, not sales pressure. A 1950s retrofit with crushed runs, freeway residue, and needing junction sealing will land at the higher end. A system that’s been maintained and has no structural issues lands at the lower end. Here’s the breakdown:
- Evaporator coil cleaning: $180-$340
- Air handler cleaning: $150-$280
- Blower cleaning: $120-$220
- Condenser cleaning: $110-$190
- Duct sealing at retrofit junctions: $90-$210

FAQs - HVAC Cleaning in San Fernando
San Fernando sits at the confluence of the I-5 and SR-14 freeways, two of the busiest diesel truck corridors in Southern California. Diesel ultrafines from that traffic get pulled into home HVAC systems through leaky retrofit duct connections and settle on duct walls. The residue is sticky, gritty, and dark brown to black. It’s not household dust, and it requires agitation tools plus HEPA filtration under negative pressure to remove, not just vacuum extraction. If a company quotes you a low flat rate without asking about your home’s proximity to the freeway corridor, they likely don’t understand what’s inside your ducts. Call (806) 606-6902 for an exact quote.
The cause is heat and age. San Fernando attics regularly reach 140°F in summer, and flex duct installed during 1940s-1960s retrofits degrades under that heat. Runs collapse, and connections at non-standard junctions pull apart. During camera inspection, we find crushed runs in roughly one out of three of these older homes. The cleaning can’t fix that; the runs must be replaced or reconnected. If a crew skips camera inspection, they won’t find the problem, and you’ll pay for a clean that doesn’t change your airflow. The fix runs $90-$210 for sealing and $120-$240 for run replacement, depending on length and access.
No. Cleaning removes what’s inside the ducts; it does nothing about how it’s getting in. San Fernando’s retrofit duct systems have gaps at plenum connections, around filter boxes, and at every non-standard junction, and those gaps are the entry points for freeway particulate. If the gaps aren’t sealed after the clean, the contamination returns within weeks. Our process includes sealing those junctions with professional duct sealant as part of the written scope. The sealing is the long-term fix; the cleaning is the reset. Call us at (806) 606-6902 to get a written price for both.
Valley summer heat does two things: it forces HVAC systems into near-continuous operation for months, cycling enormous air volumes through the air handler and blower, and it bakes the oily freeway residue onto interior surfaces. The result is a hard crust on blower fins and air handler insulation that won’t come off with brushing alone. We use mechanical agitation plus professional-grade cleaning agents rated for HVAC components. A blower clean and air handler clean on a heavily used San Fernando system typically runs $270-$500 combined, and the airflow improvement is measurable before you pay the invoice.
Expect the process to take longer than a standard clean. Expect the camera to find things you didn’t know about: crushed runs, gaps at junctions, debris traps where someone spliced two different duct materials together with foil tape. Expect a written scope that includes both cleaning and sealing, because cleaning alone won’t hold on these systems. And expect to see photos of all of it, before and after, before you’re asked for final payment. That’s the CleanRun standard, documented on every job since 2013. Call (806) 606-6902 to schedule yours.
