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 Monrovia, CA
Air duct cleaning in Monrovia costs between $380 and $690 for a whole-home system, depending on home size and contamination level, and most jobs take 3 to 5 hours. What makes Monrovia work different from surrounding cities is the ash. Homes here sit directly against the San Gabriel Mountains, and the 2020 Bobcat Fire pushed fine particulate into HVAC systems across town in volumes we simply don’t see in flatland communities a few miles south. If your system hasn’t felt clean since fall 2020, that’s not your imagination. Call (980) 447-2498 for a written quote before any work begins.
Why Monrovia Homes Are Different
Monrovia’s position at the base of the Angeles National Forest means your ducts collect what the mountains send down. Santa Ana wind events funnel through the canyons above town and drive chaparral pollen, coarse dirt, and wildfire ash into residential HVAC intakes along the north side. During the Bobcat Fire, which scorched over 115,000 acres directly above the city, fine gray-black ash settled into duct systems and never left. Technicians working homes near Monrovia Canyon Park still pull debris with that distinctive ash layer sitting atop years of standard household dust. It’s a fingerprint of the fire, and it’s one reason systems in Monrovia feel dirtier faster than homes closer to the coast.
The housing stock adds another layer. Monrovia incorporated in 1887, and many streets in Old Town and the central grid hold 1920s and 1930s Craftsman bungalows with original or piecemeal-replaced ductwork. Sheet-metal joints in these older systems separate over time, pulling dust from crawlspaces and wall cavities into the airflow. Add the South Coast Air Basin’s inversion layer, which traps smog against the foothills for days at a stretch, and Monrovia ducts accumulate fine particulate at rates measurably higher than cities even a few miles downhill. The work here is not routine. It’s specific to where Monrovia sits.
Our Main Monrovia Services
Three services cover nearly every call we handle in Monrovia, and each has its own dedicated page with pricing and local specifics. Here’s what homeowners ask about most.
Air Duct Cleaning in Monrovia
Whole-system cleaning in Monrovia means addressing what the mountains put into your ducts. We use negative-pressure extraction to pull ash, dust, and debris from the full duct run, and we replace the air filter so the system starts clean. In older Craftsman-era homes, we pay particular attention to return ducts, which tend to pull crawlspace air through separated joints. The Bobcat Fire ash we find in north Monrovia homes requires a heavier filtration setup than a standard job. Full details on process, pricing, and what to expect are on the Air Duct Cleaning in Monrovia page.
Dryer Vent Cleaning in Monrovia
Lint buildup in dryer vents is a fire risk in any city, and Monrovia’s older homes often have long, kinked vent runs that trap lint faster. We clear the entire vent path from dryer to exterior termination and check for the bypass points where lint sneaks past the trap. Many Monrovia dryers vent through roofs, which means more bends and more accumulation points than wall-vented setups. We show you before-and-after photos of your own vent so you can see the work was done. Read specifics on Dryer Vent Cleaning in Monrovia.
Air Duct Repair in Monrovia
Older duct systems in Monrovia’s prewar homes frequently develop separated joints, crushed flex runs, and torn insulation. A separated return duct pulls unfiltered air from the crawlspace into your living space, which defeats the purpose of cleaning. We inspect the full duct run, identify every separation and restriction, and repair what’s failed. Every repair carries a written guarantee, and if a covered repair doesn’t hold, we come back at no charge. The Air Duct Repair in Monrovia page covers what we fix and what it costs.
