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 Air Duct Cleaning Across Covina
Air duct cleaning in Covina typically runs $450-$900 for a full system, and the real question is not whether you need it but whether the company you call will actually document what they did. CleanRun Air Duct Cleaning serves all of Covina, from Charter Oak to the 91723 corridor north of the 10, with written pricing before any panel comes off and a camera-based photo record of every duct run when we leave. If you’ve been putting this off because the quotes feel vague or the results feel unverifiable, call (806) 606-6902 and we’ll put a number in writing before we touch anything.
Our Air Duct Cleaning crews know Covina’s housing stock: 1950s-1970s ranch homes with metal ductwork retrofitted for central AC, larger two-story additions with multiple systems, and the particulate load that comes from being at the eastern edge of the LA Basin. That local familiarity changes what we look for and what we quote.
Why CleanRun Air Duct Cleaning Is Covina’s Preferred Air Duct Cleaning Company
We have cleaned ducts in Covina homes off Citrus Avenue, up in the Rancho Vasquez area, and throughout the 91722 and 91724 zip codes. What that repetition teaches you is that every Covina home carries the same baseline problem: the valley’s trapped smog layer and wildfire ash from the San Gabriel range settle into ductwork faster here than almost anywhere else in Los Angeles County. Homeowners here aren’t asking for a luxury service. They’re asking for a fix to a recurring, documented buildup.
Tomas Reyes, who leads our crews, has walked through hundreds of Covina attics where the return plenum tells the whole story before we even start: a gray-brown cake that should not be there, mixed with fine desert dust from the last Santa Ana event. That’s what we photograph before and after, every single job. The documented record is not a marketing add-on for us. It’s the standard deliverable, and it has been since 2013.
Our Air Duct Cleaning Services in Covina
Full System Cleaning
Full system cleaning in Covina means source removal from every supply run, every return run, the main trunk line, and the plenum boxes. We use HEPA-filtered negative pressure from Abatement Technologies equipment, which matters when you’re dealing with the dense particulate cake Covina’s air deposits in ductwork. A partial cleaning that only addresses registers will leave the trapped residue in the runs themselves, and it will recirculate within weeks.
Supply Duct Cleaning
Supply ducts carry conditioned air from your furnace or air handler into the rooms of your Covina home. In a house where the central AC was retrofitted into 1960s-era ductwork, those supply runs are frequently undersized for modern tonnage and coated with decades of accumulated particulate. We clean each supply run individually and camera-inspect every one of them before we call the job complete.
Return Duct Cleaning
Return ducts pull air back to the system, and in Covina’s older homes they often run through attic spaces where failed tape seals let Santa Ana dust and wildfire ash bypass the filter entirely. We find this on a majority of jobs in the Charter Oak and Covina Hills areas. Cleaning the return side without inspecting those seals means the contamination comes back as soon as the next wind event hits.
Video Inspection
Video inspection is the difference between trusting a technician’s word and seeing the evidence yourself. After we clean, we run a camera through every accessible run and document before-and-after stills. We also look for what cleaning cannot fix: collapsed flex sections, failed seals, and gaps in the trunk line. In Covina’s aging ductwork, those structural failures are common, and finding them during a cleaning prevents a blower motor burnout months later.

BeforeAfterTrusted Brands We Service in Covina
Our crews work with professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, so the extraction and agitation systems we use are the same ones commercial HVAC contractors run. When we find a failed section in a Covina home’s aging flex duct, we can replace it with Guardsman materials on the same visit in most cases. We also service and clean systems paired with Honeywell and Aprilaire filtration components, which are common in larger Covina homes with whole-house air quality upgrades.
What We Found in a 1962 Ranch Near Charter Oak
We opened the return plenum in a single-story home off Cypress Street and found exactly what we expected: a dense gray-brown cake coating the original metal ducts, mixed with fine ash from the previous Santa Ana season. We performed full source removal using HEPA-filtered negative pressure, then camera-inspected every run. Two collapsed flex sections in the attic trunk line were starving the blower motor and had to be replaced before the cleaned system could actually move air properly. This is a common Covina scenario: the cleaning reveals the structural problem that the cleaning alone cannot fix.
Common Air Duct Cleaning Problems We See in Covina Homes
- Collapsed flex sections in attic trunk lines. The 1950s-1970s ductwork common across Covina was often retrofitted for central AC, and the flex sections added during those retrofits are now past their service life. When they collapse, debris gets trapped and airflow drops.
- Failed tape seals at joints and plenums. Decades of heat cycling in Covina’s 100°F summers degrades the adhesive on old duct tape. The gaps left behind pull unfiltered attic air and Santa Ana dust directly into the airstream.
- Dense gray-brown particulate residue. This is the signature Covina problem: trapped smog particulate and wildfire ash settling against the San Gabriel Mountains leaves a coating in ductwork that is visibly thicker than in homes 15 miles west.
- Mismatched duct sizing after AC retrofits. Older Covina homes often had central air added to duct systems designed for heating only. The undersized runs restrict airflow and trap more particulate than a properly sized modern system would.
Pricing for Air Duct Cleaning in Covina, CA
A full system cleaning for a typical single-family Covina home runs $450-$700. Larger homes with multiple HVAC systems typically fall between $650-$900 because each system gets its own written price and its own documented photo record. That per-system breakdown is the point: if a Covina house has three separate furnace and AC systems, you should see three separate line items, not one vague “whole-house” figure that leaves you guessing what was actually touched. Video inspection is included on every job, not sold as an add-on. Before we start, you get a written price for the full scope. Call (806) 606-6902 and we’ll walk through what your specific home needs.
We Also Serve Cities Near Covina
Our crews regularly work in Covina and the surrounding communities, including Azusa, West Covina, Baldwin Park, and Glendora. The housing stock and particulate exposure across the eastern San Gabriel Valley are similar, but the ductwork in each city has its own age and retrofit profile. When you call, we’ll ask about your home’s year and system setup so the first visit is useful, not a discovery mission.

FAQs - Air Duct Cleaning in Covina
In Covina, plan on every 3-4 years, versus 5-7 years in coastal communities. The reason is geographic: Covina sits at the eastern end of the LA Basin where prevailing westerly winds push accumulated smog and particulate matter against the San Gabriel Mountains, and that concentrated particulate load deposits into duct systems far faster than in Santa Monica or Long Beach. Wildfire smoke and Santa Ana dust add a second contamination wave on top of the baseline smog. If you live in Covina, you are not being oversold when a company recommends a shorter interval. Call (806) 606-6902 for an honest assessment of your system’s actual condition.
Because each system is a separate set of duct runs, a separate air handler, and a separate cleaning job. A 1970s ranch in Covina Hills with an original system plus a later two-story addition often has two or three independent HVAC systems, and a single flat quote cannot tell you which runs were actually cleaned. CleanRun’s policy under Haven Standard Clause 1 is a written price for every system before any work starts, so you can see exactly what is included and what each system costs. Bring us a competitor’s single-number quote and we’ll put our per-system breakdown next to it in writing.
Yes, and this is one of the most common scenarios we work in Covina. The original metal ducts are typically cleanable with source-removal equipment, but the flex sections added during the AC retrofit are often collapsed or torn and may need replacement, not just cleaning. We will not know until we camera-inspect the runs. The cleaning quote covers the cleaning; if we find structural failures, we document them with photos and give you a separate written price before we do any additional work.
You should expect a camera-based photo record of the inside of every duct run, before and after, delivered as part of the standard job record. You should also receive a written scope of the work performed and the written 365-Day Done Right Promise. If a company cannot show you the inside of your own ducts before and after, you have no way to verify the work happened at all. CleanRun has documented every job this way since our first one in 2013, and the photo record is included on every visit, not sold as an upgrade.
It does if the underlying seal failures and filter bypass points are not addressed. Cleaning removes the accumulated residue, but Santa Ana dust and trapped smog particulate will re-enter through any gap in aging ductwork within months. That’s why our process pairs cleaning with video inspection: we find the gaps that let the contamination back in, quote the sealing or repair separately in writing, and you decide what happens next. Call (806) 606-6902 to schedule a cleaning and inspection for your Covina home.
