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.
Fast, Reliable Air Duct Cleaning Across Covina
Air duct cleaning in Covina typically runs $350-$650 for a whole-home system, and most residential jobs are scheduled within a few days of your call. We’re Morton’s Air Duct Cleaning, and our crews work regularly in the neighborhoods between Citrus Avenue and the San Gabriel Mountains, from downtown Covina up through the Charter Oak foothills.

Call us at (323) 918-4345 for a free written estimate before any work begins.
Why Morton’s Air Duct Cleaning Is Covina’s Preferred Air Duct Cleaning Company
We’ve been part of the Cedarwell family since 2005, and our dispatch office coordinates scheduling from Los Angeles to serve Covina homes directly. Our technicians know the local housing stock: the 1950s ranch tracts off Barranca Avenue, the 1960s split-levels near Covina Park, the 1970s developments climbing toward Glendora. That matters because a crew that recognizes unsealed register boots and original fiberglass duct board can diagnose problems in minutes, not hours.
Covina customers tell us the same things after every visit. They mention the shoe covers at the door. The drop cloths laid down before equipment touches the floor. The written price they signed off on before we started, with no add-ons after. Our 365-Day Done Right Promise means if something isn’t right, we make it right. Full stop. And every job ends with a photo of the clean-up, sent before we leave your driveway.
A live person answers our phone 24 hours a day. Not a voicemail tree. Not a chatbot. Someone who can book your appointment, explain what the visit will include, and tell you exactly what it will cost.
Air Duct Cleaning Services in Covina
Air Duct Cleaning Services in Covina address a specific regional problem: the San Gabriel Mountains trap ozone and fine particulates against the city’s eastern edge, loading ductwork with ultrafine matter that coastal homes simply don’t see. Our process starts with a video inspection of your trunk lines, followed by source removal using Rotobrush agitation tools under continuous negative pressure from Nikro portable collectors. We clean every supply and return register, the main trunk, and the plenum connections at the air handler. A typical whole-home Air Duct Cleaning in Covina runs $350-$550 for homes under 2,500 square feet, and $500-$650 for larger systems or those requiring additional register boot sealing.
Residential Duct Cleaning
Our residential crews work around your schedule, including nap times and pet routines. We use quieter equipment during sensitive hours, and every technician is background-checked and uniformed. Shoe covers and drop cloths are standard, not optional.

Commercial Duct Cleaning
Small commercial systems in Covina’s retail corridors along Azusa Avenue and Badillo Street need scheduled cleaning that doesn’t interrupt business hours. We coordinate after-hours access and provide the same written upfront pricing as our residential jobs.

HVAC Duct Cleaning in Covina
HVAC Duct Cleaning in Covina goes beyond the visible registers to address the full mechanical system, including the blower motor, evaporator coil access, and air handler cabinet. Because Covina’s inland summers push air conditioning systems to near-continuous operation from June through September, blower motors work harder and pull more particulate-laden air through deteriorating duct board liner. Our HVAC Duct Cleaning includes mechanical agitation of the supply and return trunks, contact vacuuming of the blower assembly, and filter upgrade recommendations. Expect $450-$650 for a complete HVAC Duct Cleaning that includes blower service, with the final price locked in writing before we start.
Full System Cleaning with Video Inspection
We run a camera through every trunk line before and after cleaning. You see what we see: compacted debris, deteriorated liner, or unsealed boots pulling crawl-space air. No guesswork. No upsell based on scare tactics.
Supply and Return Duct Cleaning
Supply ducts push conditioned air to your rooms; returns pull it back. Both sides need attention, especially in Covina’s older homes where return plenums were often built from untreated wall cavities that collect decades of dust.
Trusted Brands We Service in Covina
Our vans carry professional-grade equipment from Nikro, Honeywell, and Aprilaire, not rental-shop tools that lose suction halfway through a job. We stock Honeywell MERV 11 and MERV 13 filters for common Covina system sizes, so your filter upgrade happens the same day as the cleaning. For homes with Aprilaire whole-house air cleaners, we keep replacement media on hand. This matters because Covina’s particulate load is heavy enough that a fresh filter immediately after duct cleaning protects your investment longer than a standard fiberglass panel would.
Common Air Duct Cleaning Problems We See in Covina Homes
- Original fiberglass duct board shedding fibers. The 1950s-1970s tract homes that dominate Covina were built with fiberglass-lined duct board that deteriorates after fifty years of blower cycles. We find loose fibers blowing through registers in homes that have never had the liner inspected.
- Unsealed register boots pulling crawl-space caliche dust. Fast-build era contractors in the San Gabriel Valley often skipped boot sealing. Our crews find fine caliche dust, the pale alkaline soil common to local foothill geology, puffing up from below every time the system cycles.
- Santa Ana wind infiltration through gaps in attic trunk lines. Fall Santa Ana events reverse normal airflow patterns and drive desert dust and ash eastward through any opening. Gaps in attic ductwork that seemed minor in spring become major contamination paths by October.
- Moisture and microbial growth from coastal influence. While Covina is inland, summer marine layer penetration and winter storms create enough humidity in duct runs to support growth on debris-coated surfaces. True source removal eliminates the organic material; fogging alone does not.

FAQs About Air Duct Cleaning in Covina
Covina’s position at the eastern end of the San Gabriel Valley traps ozone and fine particulates against the San Gabriel Mountains, so ductwork here collects heavier ultrafine loads than coastal homes. The South Coast Air Basin consistently ranks Covina among its worst air-quality zones, meaning filters clog faster and debris compacts more densely in trunk lines. Most Covina families benefit from inspection every three to five years, versus five to seven for coastal properties. Call (323) 918-4345 to check whether your system is due.
Source removal uses mechanical agitation and negative pressure to physically extract debris from duct walls; a fogging treatment only wets the surface, leaving the material in place. In Covina’s climate, moisture from fogging can actually accelerate microbial regrowth on debris that wasn’t removed, especially in humid summer months. We perform true source removal with Rotobrush and Nikro equipment, then address any remaining moisture concerns at the air handler. The result lasts longer and doesn’t introduce unnecessary chemicals into your home.
Bare sheet-metal trunk lines with unsealed register boots, deteriorated fiberglass duct board liner shedding fibers, and decades of compacted debris that filter changes never reached. In a 1962 ranch house off Charter Oak Avenue, our tech pulled registers and found bare sheet-metal trunk lines with unsealed boots, dust puffing out from the crawl space below. Using a Rotobrush agitation tool under negative pressure, we cleaned the supply and return ducts, then sealed the boots and verified with camera inspection. We installed a Honeywell MERV 11 filter at the air handler; the blower motor amp draw dropped back into range on the next service call.
Fall Santa Ana winds reverse the typical west-to-east airflow pattern across the LA Basin, driving desert dust and ash eastward through any gap in your duct system. Homes with unsealed attic trunk lines or loose return plenum connections see a second major contamination event each October through December, often worse than summer AC loading because the particles are coarser and more abrasive to blower motors. We inspect for these infiltration paths during every cleaning.
Yes, if the blower wheel and housing are coated with debris, the motor works harder and distributes particulate back into supposedly clean ducts. Our HVAC Duct Cleaning includes contact vacuuming of the blower assembly and inspection of the evaporator coil access panel. In Covina’s heavy-particulate environment, a clean blower can drop amp draw significantly, which you see on your electric bill. We include this in our written price when it’s needed, never as a surprise add-on.
