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.

AfterAir Duct Cleaning Company in Covina, CA
Covina homes trap dust differently than most of the San Gabriel Valley. The city sits against the foothills, and when the Santa Ana winds push through the canyons, fine particulate settles into older duct runs, especially in the 1950s and 60s era homes between Badillo Street and the 10 freeway. Most standard air duct cleanings in Covina run $350 – $650 for a typical 3-bedroom home, and our technicians can usually complete the job in a single visit. Call Cardinal Air Duct Cleaning at (737) 727-2314 when you’re ready for a written price before we touch a single vent.
Why Covina Homes Are Different
Covina’s housing stock tells a story in layers. The neighborhoods north of San Bernardino Road trend toward mid-century construction, with metal ducting that predates modern insulation standards. South of the 10, you’ll find newer flexible ductwork, but it often runs through attics that hit 140 degrees in July, baking dust into the liner. Homes around Charter Oak and the Covina Hills area deal with wildfire smoke drift from the Angeles National Forest during fire season, and that residue settles in return air ducts within weeks, not months.
The terrain matters too. Covina’s older subdivisions sit on gentle slopes, and we regularly see duct runs where settling has opened small gaps at the plenum connections, pulling in attic dust and insulation fibers. Most HOAs in Covina don’t restrict duct cleaning since the work happens entirely inside the home, and no permit is required for standard cleaning on single-family residences. What does vary is access: some closets in the Rancho and Sierra Madre corridor homes are tight, so we bring compact Nikro HEPA extraction units that fit where larger rigs won’t.
Our Main Covina Services
Most Covina homeowners reach out to us for one of three services, and each has its own dedicated page with deeper detail on pricing, timing, and what to expect on the day of the job.
Dryer Vent Cleaning in Covina
Dryer vents in Covina run longer than average in two-story homes near the Covina Hills, and every extra foot of duct creates more surface area for lint to accumulate. Combine that with the dry, windy months from September through November, and a clogged vent turns from a slow-drying nuisance into a fire hazard faster than most people realize. We use professional rotary brush systems to cut through compacted lint without damaging the vent run, and every job includes verification with an airflow meter so you know the vent is drawing properly.

Air Duct Cleaning in Covina
Air duct cleaning in Covina means addressing what’s actually inside your system: years of dust, pet dander, and often construction debris from past remodels that never got extracted. We run Rotobrush rotary brush systems paired with Nikro HEPA-rated negative-pressure vacuums, meaning the loosened debris goes straight into the vacuum, not back into your living room. For homes with older metal ducts or yellowed flex lines, we inspect the interior with a camera before and after so you see exactly what was removed. Read more on our Air Duct Cleaning in Covina page.
HVAC Cleaning in Covina
HVAC cleaning goes beyond the ducts and into the blower assembly, evaporator coil, and return plenum, which is where a lot of Covina’s dust actually gets trapped. The coil is the wet, cool surface in your air handler; when it’s caked with dust, your system loses efficiency and pushes musty air through every register. We open the access panels, clean the coil and blower wheel with commercial-grade cleaners, and sanitize the condensate pan. It’s the service we recommend before peak summer, when Covina’s air conditioning demand peaks. Full scope on our HVAC Cleaning in Covina page.

No. Duct cleaning is an interior maintenance service, and no Covina HOA or city permit is required for standard residential work. The only exception would be accessory dwelling units, but even then the cleaning itself is exempt. Your written quote covers the full scope before we start.
