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.
Air Duct Cleaning Company in San Marcos, TX
Air duct cleaning in San Marcos, TX means dealing with a specific combination of inland valley heat, Santa Ana wind events, and a housing stock that mostly went up between the late 1980s and mid-2000s. Those 20 to 35 year old flexible fiberglass duct systems run hard through long, hot summers, and when the wind pushes chaparral dust and wildfire smoke into the valley, it ends up inside your return-air system, not just on your patio furniture. We’re Linden Air Duct Cleaning, and we approach every San Marcos job with that reality in mind. Call us at (980) 447-2498 to talk through what’s happening in your home.
Why San Marcos Homes Are Different
San Marcos sits in an inland valley that funnels Santa Ana wind events far more intensely than coastal neighbors like Carlsbad or Oceanside. That’s not a small detail. When the wind kicks up, it drives fine chaparral dust and wildfire smoke directly into homes before anyone has a chance to close windows and doors. The 2014 Cocos Fire, which ignited near Cal State San Marcos and burned roughly 1,900 acres through the city’s residential corridors, left ash and smoke particulate in surviving homes’ duct systems. Many of those systems have never been professionally cleaned since.
Add to that the housing stock. The vast majority of San Marcos residential neighborhoods were built during the city’s rapid tract-home expansion from the late 1980s through mid-2000s, which means duct systems are now 20 to 35 years old and commonly use flexible fiberglass ductwork. That material sags, tears at joints, and holds onto accumulated debris in a way older galvanized steel does not. Technicians working the neighborhoods around Twin Oaks Valley Road and the Cal State San Marcos corridor routinely find residual ash deposits in return-air plenums of homes that survived the Cocos Fire. It’s a decade-old contamination layer that standard filter changes never address, and most homeowners have no idea it’s there.
Summers here are hot. Highs regularly reach the low-to-mid 90s°F with lower humidity than the coast, which translates to longer AC run times and faster dust loading in return-air systems. San Marcos ductwork simply collects more, faster, than a coastal home’s system would.
Our Main San Marcos Services
San Marcos homeowners most often call us about two things: air duct cleaning and dryer vent cleaning. The third service we provide here, air duct repair, often follows from what we find during a cleaning.
Air Duct Cleaning in San Marcos
Our air duct cleaning service uses negative-pressure extraction to pull accumulated dust, ash, pet dander, and debris out of your duct system without scattering it through the house. In San Marcos, we pay particular attention to return-air plenums, where Cocos Fire ash tends to settle and linger. The process covers supply and return ducts, registers, and the air handler. Every job starts with a written price before any work begins, so you know the full cost up front. Air Duct Cleaning in San Marcos has the full breakdown of what the job involves and what it costs.

Dryer Vent Cleaning in San Marcos
Dryer vent cleaning removes lint buildup from the vent line that runs from your dryer to the outside of your home. In San Marcos, many dryer vents exit through the roof or along exterior walls where they’re exposed to that same chaparral dust and wind-driven debris. A clogged dryer vent makes your dryer work harder, wastes energy, and is a serious fire hazard. We use equipment from trade-trusted brands including Rotobrush to break through lint blockages, including the dryer vent lint trap bypass that most homeowners never see. Dryer Vent Cleaning in San Marcos covers pricing and what to expect.

Air Duct Repair in San Marcos
After 20 to 35 years in service, San Marcos flex-duct systems fail at the seams. Sagging runs, torn joints, and disconnected sections pull attic dust and unconditioned air into your ducts and drive up your energy bills. Air duct repair addresses those failures directly. Every repair we make in San Marcos is covered by a written guarantee with a free second visit if the repair does not hold. That’s our standing commitment, not a promotional offer. Air Duct Repair in San Marcos explains what we fix and how the guarantee works.

Pricing for Air Duct Cleaning Company in San Marcos, TX
| Service | Typical range in San Marcos |
|---|---|
| Air duct cleaning (whole home) | $450 – $950 |
| Air duct cleaning (condo or small home) | $300 – $450 |
| Dryer vent cleaning | $99 – $199 |
| Dryer vent cleaning with roof access | $150 – $250 |
| Air duct repair (minor, single point) | $95 – $195 |

| Return-air plenum cleaning (Cocos Fire ash removal) | $120 – $220 |
What pushes a San Marcos job toward the higher end of those ranges is usually the age and condition of the ductwork. A 35 year old flex-duct system with sagging runs and torn joints takes longer to clean properly than a newer, tighter system. Whatever the price, you get it in writing before any work begins, and that written price does not change mid-job.
