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 Lake San Marcos, CA
Air duct cleaning in Lake San Marcos typically runs $350 – $650 for a whole-home system, with most jobs scheduled within a week and completed in a single visit. The 1970s and 1980s housing stock here, much of it originally built with electric forced-air heat pumps, means we’re often cleaning legacy ductwork that’s been modified, extended, or left with abandoned runs after decades of HVAC upgrades. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and we serve Lake San Marcos with written upfront pricing, background-checked uniformed technicians, and the 365-Day Done Right Promise on every job. Call us at (361) 326-5060 for a free estimate.
Why Lake San Marcos Homes Are Different
Lake San Marcos isn’t a typical suburban grid. It’s a tight, lake-centered community where most homes date to the late 1960s through the 1980s, and many were built with electric forced-air systems that have seen multiple HVAC upgrades over the years. Those upgrades often left behind mismatched flex duct, abandoned trunk lines, and connections that never got properly sealed. When we clean ducts here, we’re not just vacuuming debris, we’re mapping what’s actually still in use and what’s been left to collect dust in attics or crawlspaces.
The inland North County climate works against these systems too. Hot, dry summers pull dust and allergens through every gap, while mild, damp winters can let moisture sit in unconditioned attic ducts and crawlspace runs. We’ve found moisture stains and even rodent nesting evidence in lakefront homes where ducts pass through unconditioned spaces. And because Lake San Marcos is heavily HOA-governed, scheduling often requires coordinating with association rules and working around lake-adjacent access constraints that don’t exist in standard subdivisions. Wildfire smoke events in the region can also force ash and soot into HVAC systems, creating sudden spikes in demand for thorough duct cleaning.
Our Main Lake San Marcos Services
Homeowners in Lake San Marcos call us most often for these three services, each with its own dedicated local page:
Air Duct Cleaning in Lake San Marcos
Our rotary brush system, powered by Rotobrush equipment, agitates debris from duct walls while a high-capacity vacuum pulls it out of your home. In Lake San Marcos, we often find that original rigid metal trunks have been patched with flex duct that sags or leaks at the joints, so our technicians inspect for airflow restrictions while they clean. We use negative-air methods from Nikro when the buildup is heavy or when mold is suspected from winter moisture exposure. Every job gets a written price before we start and is covered by our 365-Day Done Right Promise. Air Duct Cleaning in Lake San Marcos
Dryer Vent Cleaning in Lake San Marcos
Dryer vent cleaning in Lake San Marcos addresses a real fire hazard that builds faster than most homeowners expect. The same dry climate that fills ducts with dust also creates ideal conditions for lint accumulation, and many older homes here have vent runs that are longer or more convoluted than modern codes allow. Our technicians use professional-grade brushes and high-velocity air to clear the full run from dryer to termination, checking for proper airflow at the exterior cap. We document the before-and-after with photos you can see. Dryer Vent Cleaning in Lake San Marcos
Duct Sealing in Lake San Marcos
Duct sealing in Lake San Marcos often delivers the biggest comfort improvement for the investment, especially in homes where decades of modifications have left joints and connections leaking conditioned air into attics and crawlspaces. We apply mastic sealant and mechanical fasteners to accessible joints, and we use pressure testing to verify results. For Lake San Marcos homes with unconditioned crawlspace or attic runs, sealing can drop energy bills measurably and reduce the dust load that makes cleaning necessary more often.
