We’ve been driving the same Covina streets for over 42 years, from the older ranch blocks off Citrus Avenue in 91722 to the hillside homes above Azusa Avenue in 91724. Our technicians know which houses were built on former citrus grove land, which neighborhoods still run original 1950s duct board, and why a standard cleaning quote from a coupon outfit can turn into a bait-and-switch when they discover what Covina’s aging systems actually contain. We don’t operate that way. One price, shown before we start, backed by our 90-Day Done Right Promise in writing.
Why Bellows Air Duct & Vent Co. of California Is Covina’s Preferred Air Duct Cleaning Company
Our reputation in Covina was built house by house, not through mailers. Homeowners here call us back because the job gets done right, and if it doesn’t, we return at no charge with no paperwork to file. That 90-Day Done Right Promise is stamped on every invoice.
Our response time to Covina averages under 90 minutes during business hours because our Los Angeles-based crews know the San Gabriel Valley corridor well. We don’t route you through a call center in another state. A live person answers our phones 24 hours a day, and that person knows where Covina sits relative to the 210 and the 10.
We carry parts from Nikro, Honeywell, and Aprilaire on our trucks, so most Covina repairs don’t require a return trip. Our technicians are uniformed, background-checked, and trained to recognize the specific failure modes of Covina’s mid-century housing stock, something a discount operator with a Rotobrush rental and a coupon won’t catch.
Our Air Duct Cleaning team has handled everything from routine maintenance on newer West Covina systems to full containment jobs on delaminated duct board in original 91722 ranches. The difference is in what we find, and what we do about it.
Our Air Duct Cleaning Services in Covina
Residential Duct Cleaning
Covina’s single-family homes, particularly the ranch-style tracts built in the 1950s and 1960s, present a specific challenge: decades of accumulated debris in ductwork that was never designed for today’s air quality conditions. A typical residential duct cleaning in Covina runs $350-$650 for a standard system, $750-$1,200 if we find degraded duct board requiring containment or replacement. We clean supply and return lines, registers, and the main trunk, then verify with camera footage before and after. Most Covina residential jobs finish in three to five hours.
Commercial Duct Cleaning
Covina’s commercial core along Arrow Highway and the older retail strips near Citrus Avenue includes restaurants, medical offices, and small industrial spaces with duct systems that see heavier loading than residential. Commercial duct cleaning in Covina typically starts at $800 and scales with system complexity. We work after-hours to avoid disrupting your business, and we provide documentation for insurance or health department requirements.
Supply Duct Cleaning
Supply ducts push conditioned air into your living spaces. In Covina, these lines often show the heaviest contamination because they’re the path of least resistance for Santa Ana wind debris and trapped smog particulates. Supply duct cleaning alone runs $200-$400 in Covina, though we generally recommend full system cleaning for homes with original ductwork. Our technicians inspect each supply boot for cracks where valley soil infiltrates, a common find in 91723 and 91724 homes near the foothills.
Return Duct Cleaning
Return ducts pull air back to your HVAC unit, and in Covina’s older homes they’re frequently undersized or partially collapsed where flexible duct was retrofitted in the 1980s. Return duct cleaning in Covina costs $250-$450, but we often find that restricted returns are the real problem, not dirt. Our camera inspection shows you exactly what’s happening in that dark crawl space or attic.
Full System Cleaning
This is what most Covina homes need, especially those built before 1970. Full system cleaning covers supply and return ductwork, registers, grilles, the air handler cabinet, and the blower assembly. In Covina, full system cleaning runs $550-$850 for a typical ranch home, with older systems at the higher end if we encounter degraded duct board or hidden mold from past moisture intrusion. We include before-and-after video documentation with every full system cleaning.
Video Inspection
Every Bellows job in Covina starts with video inspection, not as an upsell but as standard practice. You see what we see: fiberglass liner shedding, collapsed flex duct, rodent debris, or the fine black layer of PM2.5 that accumulates in San Gabriel Valley systems. For Covina homeowners considering whether to clean or replace, our video inspection provides the evidence to make that decision with confidence. Standalone video inspection for diagnostic purposes runs $150-$250.

Trusted Brands We Service in Covina
We stock parts and equipment from Nikro, Honeywell, and Aprilaire on our Covina service trucks, the same brands serious HVAC contractors specify for commercial installations. Nikro’s HEPA vacuums handle the containment work when we find degraded duct board in older Covina homes. Honeywell and Aprilaire air cleaners integrate with existing systems for homeowners who want ongoing filtration after cleaning. Because we carry inventory locally, most Covina repairs don’t wait on shipping. If your system needs a component we don’t stock, our Los Angeles warehouse typically has it next business day.
Common Air Duct Cleaning Problems We See in Covina Homes
- Fiberglass liner shedding from original duct board. We serviced a 1958 ranch on Center Street in 91722 where the original duct board liner had delaminated, sending fiberglass fragments into the airstream. Our Rotobrush and HEPA-vac system contained the debris, but we recommended a full system replacement given the advanced degradation. This is far less common in West Covina’s newer construction.
- Santa Ana wind infiltration overwhelming standard filters. Each fall, fine clay-rich soil from the valley floor pushes into Covina homes through gaps in windows, doors, and attic hatches. Standard 1-inch filters can’t capture these particles, and they accumulate in ductwork until a deep clean removes them.
- Thermal inversion trapping smog and wildfire smoke. Covina’s position in the San Gabriel Valley smog pocket means duct systems load with PM2.5 faster than coastal areas. After cleaning, thorough drying is essential; trapped moisture in old duct board can lead to hidden mold growth.
- Collapsed or disconnected flex duct from 1980s retrofits. Many Covina ranch homes had original metal or duct board supplies replaced with early flex duct that has sagged, torn, or pulled loose at joints. We find this regularly in crawl spaces beneath 91723 homes, where airflow has been silently restricted for years.

FAQs - Air Duct Cleaning in Covina
Original fiberglass duct board in 1950s-60s Covina homes, especially in 91722 off Citrus Avenue, degrades from the inside out as thermal cycling and moisture break down the resin binding the fiberglass mat. Cleaning can remove loose surface material, but once the liner begins delaminating, the shedding continues until the duct board is replaced. We flag this during our initial camera inspection and give you a straight recommendation: contain and replace, or accept that particles will persist. Call (855) 401-6006 for a video inspection and honest assessment.
Most Covina homes need duct cleaning every 3-5 years, but homes in the smog pocket near the 210 corridor or with original 1950s-60s ductwork should consider every 2-3 years. The South Coast AQMD’s unhealthy air days deposit fine particulates that standard filters miss, and Santa Ana wind events add seasonal loading. If someone in your home has asthma or allergies, more frequent cleaning makes sense. We’ll tell you honestly if your system doesn’t need it yet.
Duct cleaning removes the organic material that feeds odor, but if the smell comes from mold in degraded duct board or a chronically damp crawl space, cleaning alone won’t solve it. Our camera inspection locates the source. Musty smells in Covina’s older homes often trace to past roof leaks that soaked attic ductwork, or to high humidity in crawl spaces where flex duct sags and pools condensation. We fix what we find, or tell you what contractor you need instead.
Expect us to start with a full video inspection, then contain the work area because original duct board this old often surprises us. We use HEPA-contained Rotobrush equipment and negative air machines to capture debris. The job takes 4-6 hours for a typical Covina ranch. We’ll show you the before-and-after footage, explain any integrity failures we found, and give you a written quote for repairs or replacement if the duct board won’t hold up. Most importantly, you’ll know exactly what you have, not guess.
Yes. Santa Ana wind events, typically October through January, drive fine clay-rich soil into Covina homes through every gap in the building envelope. We see a spike in calls each November from homeowners whose filters clogged and whose ducts loaded with visible dust. If you’re due for cleaning, scheduling before Santa Ana season prevents the worst loading. If you’ve just had a major wind event, wait two weeks for dust to settle, then call for inspection.
