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.

San Dimas sits in the San Gabriel Valley east of Los Angeles, where dry desert winds, heavy spring pollen from the foothills, and an aging housing stock combine to make air duct cleaning a seasonal necessity rather than a luxury. The city’s strong equestrian culture and proximity to the Angeles National Forest mean ducts often collect not just dust but also fine trail dust and animal dander, requiring specialized filtration. We dispatch crews from our Los Angeles office and serve San Dimas homes directly.
Why San Dimas Homes Are Different
Much of San Dimas was built up in the 1960s through 1980s, with tract homes featuring original galvanized or early flexible ductwork that frequently harbors decades of dust, pollen, and sometimes rodent debris. Newer infill developments and custom homes in the foothills often have more complex, multi-zone HVAC systems. This split housing stock means we arrive with two different tool kits: rotary brush systems for the older rigid ducts, and negative-air machines with softer agitation for the newer flexible lines.
San Dimas has a hot-summer Mediterranean climate with dry, windy springs that usher in pollen and dust from the nearby San Gabriel Mountains, and autumn Santa Ana winds that can push ash and debris into outdoor HVAC intakes. These seasonal events drive a spike in duct cleaning demand each spring and fall. Local technicians know that after the Santa Ana winds, calls spike for duct cleaning in the older neighborhoods near the foothills, where original ductwork acts like a sieve for fine ash and dust that settles deep in the system.

Dryer Vent Cleaning in San Dimas
Lint buildup in dryer vents is a leading cause of house fires, and San Dimas homes with longer vent runs through attics or crawl spaces are especially vulnerable. We clear the full run from the dryer connection to the exterior termination, measuring airflow before and after to verify the job. In the foothill neighborhoods where vent runs can exceed 25 feet, we bring extension tools and inspect for proper slope and support. Dryer Vent Cleaning in San Dimas
Duct Sealing in San Dimas
Leaky ducts waste 20 – 30% of conditioned air in typical San Dimas homes, with older galvanized systems especially prone to separations at joints and seams. We seal accessible ductwork with mastic and mesh reinforcement, then pressure-test to verify improvement. Foothill homes with multi-zone systems often need targeted sealing at zone dampers, where temperature differentials cause repeated expansion and contraction. Duct Sealing in San Dimas
