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
Air duct cleaning in Covina runs between $395 and $950 for most single-family homes, depending on system size and how long the ducts have gone without service. Covina’s older ranch-style housing stock, paired with San Gabriel Valley air that carries smog, ash, and wildfire particulates, means ducts here collect a different kind of buildup than coastal neighborhoods. If your system hasn’t been opened up in years, call us at (469) 972-3151 and we’ll give you a written price before any work begins.
Why Covina Homes Are Different
Covina sits in a topographic bowl at the base of the San Gabriel Mountains. That geography does something specific to the air: when wildfire smoke from Angeles National Forest drifts south, it settles into the valley and stays there, cycling through residential HVAC systems for days at a time. The same inversion layer that traps smog over the San Gabriel Valley also traps the fine ash and particulate matter your return vents pull into the ductwork. Homes in Covina aren’t just dustier than coastal LA homes – they’re filtering the same degraded air over and over, and that load lands directly in the ducts.
The housing stock compounds the problem. Most of Covina’s residential core was built between the 1950s and 1970s, and many of those original ranch-style tract homes had central forced-air systems retrofitted after construction. That means aging flex duct and early fiberglass-lined metal ducts that, in some cases, have never been opened. Around downtown Covina and the older neighborhoods off Citrus Avenue, technicians regularly find inner fiberglass liner that has crumbled after 50-plus years of heating and cooling cycles. The duct isn’t just dirty. It’s shedding insulation particles into the air your family breathes.
Summer temperatures routinely pass 100°F in Covina, which pushes AC systems into near-constant operation from June through September. Every hour that system runs, it’s pulling valley air through the return registers and depositing whatever is in that air onto the duct walls. Then Santa Ana winds arrive in the fall and add a fresh layer of fine debris from mountain wildfires. The result is a duct system that needs attention more regularly than a comparable home in, say, Long Beach or Torrance would.
Our Main Covina Services
Covina homeowners call us most often about two jobs: cleaning the HVAC ducts that move heated and cooled air through the house, and clearing dryer vents that fill with lint faster than homeowners expect. Each service has its own Covina page with full pricing and detail.
Air Duct Cleaning in Covina
Our Air Duct Cleaning in Covina work starts with an inspection of your system, including the return side, supply registers, and the main trunk lines. We use negative-air extraction, which means a powerful vacuum creates suction at one end of the system while rotary brush agitation loosens debris at the duct walls – so the dust and ash get pulled out rather than blown into your living space. In Covina’s older homes, this often includes removing crumbled fiberglass liner fragments that have been circulating for years. We also inspect the flex duct runs that retrofit systems often used, because those connections loosen over time and pull unfiltered attic air into the airstream. Every job includes a written price agreed to before we open the first register.
Dryer Vent Cleaning in Covina
Our Dryer Vent Cleaning in Covina service clears the full run from the dryer’s lint trap bypass to the exterior vent termination. That bypass is the internal chamber where lint collects before the exhaust pipe, and in Covina’s 1960s and 1970s homes, the exterior terminations are often located on roofs or through long walls with several elbows – configurations that collect lint in the bends and restrict airflow. A restricted dryer vent forces your dryer to work harder, which adds drying time and creates a fire hazard from built-up lint near the heating element. We clean the entire run and verify airflow at the termination point before we call the job done. The Kingswell Guarantee applies to every dryer vent job, with a written price handed to you before work starts.

What Covina Customers Say
"My wife's allergies were awful every morning. Had the ducts done and it's made a real difference. Tech was on time and wore booties in the house without me asking."
- Rob Pendergast"Bought an older home and the previous owners had pets everywhere. After Kestrel did the ducts the stale smell was just gone. On time, quick, and they showed me the filter they pulled."
- Preston Ngata"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
