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 Valencia
HVAC cleaning in Valencia typically costs between $380 and $720 for a complete system, depending on the number of duct runs, accessibility of the air handler, and whether coil cleaning or blower cleaning is included. Most jobs are completed in a single visit, with a written price agreed before any work starts. We’re based in Los Angeles and dispatch crews into Valencia regularly, so scheduling is straightforward and we’re familiar with the village layouts, garage-mounted air handlers, and aging flex duct that define this community.
If you want a documented record of what was actually inside your ducts before and after the work, call (806) 606-6902. Tomas Reyes leads the team and every job includes the photo record we’ve provided since our first job in 2013.
Why CleanRun Air Duct Cleaning Is Valencia’s Preferred HVAC Cleaning Company
Valencia homeowners tend to research before they make contact. They want to see evidence: a written scope, a photo record, a name attached to the work. That’s how we’ve operated since 2013, across more than 52,000 homes, and it’s why the decision usually comes down to what a company can show rather than what it claims. In Valencia specifically, we hear the same three complaints: dusty supply registers even after a “cleaning,” a persistent musty smell from the vents, and a system that runs constantly in summer yet struggles to hold 72°F. Each one points to the same underlying issue: source-level debris that was never actually removed.
Our technicians are background-checked, uniformed, and identified by name before arrival. Under the H.A.V.E.N. Standard, every job starts with a written price, proceeds with source removal under negative pressure, and concludes with a photo record of every duct run, inside and out. That’s the documented evidence a written warranty can attach to. The 365-Day Done Right Promise is in writing on every job: if the work isn’t right, we make it right. Not a manager’s discretion. A written guarantee.
Our HVAC Cleaning Services in Valencia
Air Handler Cleaning
The air handler is the heart of a Valencia HVAC system, and in this city, it’s often mounted in a garage that seals imperfectly against Santa Ana winds. We clean the blower housing, evaporator coil compartment, drain pan, and cabinet interior, then seal the return seams so fine Mojave particulate stops getting pulled into the blower during high-wind events. The garage-mount configuration means dust ingestion from wind-driven grit is a genuine, recurring issue here. It’s one of the cleanings we recommend most often for Valencia tract homes built in the 1970s through 1990s.
Evaporator Coil Cleaning
In Valencia, evaporator coils run under load from May through October. When the coil is fouled with a layer of dust and the biofilm that forms in hot, humid conditions, the system works longer to hit the set point. That means higher energy draw and warmer supply air. We clean the coil with professional-grade equipment from Rotobrush and Guardsman, removing the debris layer and restoring airflow. A clean coil in Valencia isn’t a luxury add-on; it’s the difference between a system that cycles normally and one that runs flat-out in 103°F heat.
Blower Cleaning
The blower wheel accumulates dust and, in Valencia’s heat, often a baked-on film that reduces airflow and can throw the motor out of balance. We clean the blower using Nikro equipment, then check the motor’s amp draw to verify it’s running within range. Homes near the 5 Freeway and Route 126 corridors have a predictable issue: fine road dust and particulate that works its way into the blower housing far faster than in coastal neighborhoods. If your system sounds louder than it should or airflow at the registers has dropped, the blower is usually the first place to look.
Condenser Cleaning
The outdoor condenser coil on a Valencia home fights a different battle than the indoor components. Summer heat, airborne silt from the Santa Clarita Valley, and occasional ash from hillside fires all coat the coil fins. We clean the condenser coil and check the refrigerant pressures after the job to document where the system stands. A condenser that’s dropping efficiency in July is a system that’s overworking every other component, and in this heat, failures cascade.

BeforeAfterTrusted Brands We Service in Valencia
Most of the equipment in Valencia homes carries familiar nameplates: Honeywell controls, Aprilaire filtration, and a mix of manufacturer brands on the handler and condenser. We service all makes and models, and we use professional-grade cleaning equipment from Rotobrush, Nikro, and Guardsman on the job itself. Those names matter because they’re verifiable: before you agree to a price, you can look up what we’re running and what it’s designed to do. We don’t arrive with a shop vac and a dust mask.
Common HVAC Cleaning Problems We See in Valencia Homes
Valencia’s master-planned villages may differ in layout, from the original 1970s tracts off McBean Parkway to the newer builds near Newhall Ranch Road, but the failure patterns are remarkably consistent. Over the years, and hundreds of Valencia jobs, we’ve documented the same issues repeatedly:
- Delaminating flex duct in original 1970s-1980s villages: The inner liner of original flex duct breaks down after four decades of near-continuous summer use, releasing fiberglass particles into the supply air. This is not something a surface clean fixes; the affected runs need replacement.
- Garage-mounted air handlers with unsealed return seams: The cabinet return path pulls in dust and debris from the garage, and in Santa Ana conditions, the negative pressure actively sucks fine particulate into the system. Sealing the seams is part of a proper clean; skipping it means the system re-contaminates itself within weeks.
- Supply-only cleanings that miss the return ducts: During May-October continuous running, return ducts accumulate dust faster than supply runs. A crew that cleans only the supply registers leaves the reservoir untouched.
- Fogging “sanitiser” jobs that mask odor instead of removing source material: In Valencia’s heat-trapped valley, microbial growth inside the ducts reappears quickly when the debris isn’t physically removed. Fogging a chemical into the system doesn’t take out the food source. Source removal does.
Pricing for HVAC Cleaning in Valencia, CA
Straight numbers: a single-system HVAC cleaning in a Valencia tract home, with both supply and return ducts, blower cleaning, and evaporator coil cleaning, typically runs $480 to $720. A partial job, like coil-only or blower-only service, ranges from $180 to $340. Flex duct replacement, which we recommend when the original liner has delaminated, adds $45 to $75 per run depending on access. We price this in writing before work starts, every time. That’s Haven Standard Clause 1. You see the number, you approve it, and the number does not change after the truck arrives.
What drives the price down is a simple system with clear access; what drives it up is a tight crawlspace, two air handlers, or significant liner deterioration. We’ll give you the written number up front, and we’ll include a Free Second Opinion on any written estimate you’ve already received. We’re not afraid to put our number next to a competitor’s quote.

FAQs - HVAC Cleaning in Valencia
Valencia sits in the Santa Clarita Valley, one of the hottest inland pockets in LA County, where summer temperatures routinely hit 100-108°F and central air systems run almost continuously from May through October. That constant runtime, combined with Santa Ana wind events that funnel fine Mojave particulate through the valley’s passes and into any duct gaps, means Valencia homes accumulate duct debris significantly faster than coastal communities just 25 miles away. Annual or biennial cleaning here is a genuine operational necessity, not a marketing line. Call (806) 606-6902 for an exact quote on your system - the estimate is free.
No. Fogging a sanitiser into a duct system without first removing the debris that feeds microbial growth is the equivalent of spraying air freshener over an unwashed drain. In Valencia’s heat-trapped valley, the biofilm and organic dust that support microbial growth return within weeks if the source material is left in place. What actually works is physical source removal under negative pressure with HEPA filtration, followed by a documented photo record of every run. If a bid includes only fogging, ask what they’re removing and ask for photos. If they can’t show removal, they haven’t done the core work. Our standard job includes source removal and the photo record. Call (806) 606-6902 to see what that looks like, in writing.
The inner liner of the original flex duct delaminates. Those systems were installed when Valencia homes ran air conditioning far fewer hours per year, and four decades of near-continuous summer operation in triple-digit heat has exceeded the manufacturer’s expected lifecycle. The liner breaks down and sheds loose fiberglass particles directly into the supply air. We regularly document this with camera inspection in the original villages off McBean Parkway, Northbridge, and around Valencia High School. The fix is replacement of the affected runs, not a cleaning. If you’re seeing white specks around your supply registers, that’s a strong indicator. Call (806) 606-6902 and we’ll put a camera in your ducts.
Santa Ana winds push fine Mojave-desert particulate against the garage door seals and through any gaps in the air handler cabinet’s return path. The negative pressure created by the blower actively pulls that dust into the blower housing and over the coil. In homes with garage-mounted handlers, which are extremely common across Valencia’s villages, this is the single biggest re-contamination source we document. The fix is not a one-time cleaning; it’s cleaning plus sealing the cabinet’s return seams so the system stops pulling in wind-driven grit. Our complete Air Handler Cleaning includes that sealing step specifically because of how often we see this failure mode in Valencia. Call (806) 606-6902 for a written quote on handler cleaning with return-seam sealing.
Yes. When hillside fires in the Santa Clarita Valley push smoke and ash across the Placerita Canyon corridor into Valencia, fine particulate enters homes through the return air path and can settle deep in the duct runs. A routine cleaning doesn’t address the microscopic smoke particulate that adheres to the duct walls and coil surfaces. What’s needed is source removal under negative pressure with HEPA filtration, exactly the equipment we run on every job with Rotobrush and Nikro systems. If you’ve had smoke intrusion during a Santa Clarita Valley fire event, call (806) 606-6902 and ask about smoke-specific duct remediation. We’ll document what’s in your system and give you a written price before any work starts.
