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.

We know this area. Timberwood Park’s unincorporated Hill Country setting means unpaved roads, open oak savanna, and winter cedar season that loads HVAC systems differently than suburban San Antonio. Our technicians are background-checked, uniformed, and trained to The Garrison Code: price in writing before touching equipment, leave the site clean, and stand behind the work for 365 days.
Why Hollis Air Duct Cleaning Is Timberwood Park’s Preferred Air Duct Cleaning Company
We’ve been part of the Garrison Partners family since 2004, and our Air Duct Cleaning team has built a reputation in Bexar County’s northern Hill Country by showing up when we said we would and pricing jobs before we start them. Timberwood Park homeowners don’t call us for the lowest teaser quote; they call us because the last crew quoted one price on the phone and handed them a bill for double at the door. That doesn’t happen here. The price is written down. It doesn’t move.
Our technicians arrive in marked vehicles, uniformed, with the Rotobrush and Nikro systems already loaded. Phones are answered by a live person 24 hours a day, 7 days a week, so you’re not leaving voicemail when cedar season has your returns clogged and your allergies flaring. Every job carries the 365-Day Done Right Promise: if the work fails within a year, we return and make it right at no charge, including a free second visit.
We understand the local housing stock. Most Timberwood Park homes were built between the 1990s and 2020s as custom or tract-built single-family homes on 1 – 5 acre lots, with flexible duct runs in unconditioned attics and often two or more HVAC zones. That layout changes how we approach the job, how long it takes, and what equipment we bring. We don’t treat a Timberwood Park property like a standard suburban ranch.
Ductwork Cleaning in Timberwood Park
Ductwork Cleaning in Timberwood Park means removing the accumulated cedar pollen, limestone dust, and seasonal debris that gets drawn into return air systems between January and March, then addressing the mold and mildew that can grow in attic flexible ducts during our hot, humid summers. A typical residential Ductwork Cleaning in Timberwood Park runs $350 – $550 for a single-zone system and $500 – $650 for properties with two or more zones; if leaks are found during service, we also offer Duct Sealing in Timberwood Park to restore efficiency. Commercial systems and outbuilding air handlers are priced separately after inspection.
We use rotary brush agitation under negative pressure, which means the Rotobrush scrubs the interior duct walls while a Nikro negative-air machine pulls the loosened debris into a sealed HEPA-filtered collection unit. Nothing gets blown back into your living space. For Timberwood Park’s flexible attic runs, we adjust brush speed and vacuum strength to avoid damaging the ductwork.
Post-Cedar-Season Scheduling
Most Timberwood Park homeowners who struggle with winter allergies benefit from scheduling Ductwork Cleaning in late February or March, after the January – February Ashe juniper peak has deposited its fine yellow coating in returns and blower compartments. Cleaning in summer or fall misses this loading cycle and leaves you breathing that residue until the next cedar season starts.
Wood Heat and Hybrid Systems
Homes with supplemental wood stoves or fireplaces see additional soot and ash particles drawn into return air. We inspect for combustion byproduct residue during Ductwork Cleaning and can recommend filtration upgrades using Honeywell or Aprilaire media filters sized to your system.
Air Duct Inspection in Timberwood Park
Air Duct Inspection in Timberwood Park gives homeowners a clear picture of what’s inside their ductwork before any cleaning begins, using video camera systems that navigate the flexible attic runs common in local subdivisions. A standalone inspection runs $150 – $250; if you proceed with cleaning, we apply that fee toward the job. We recommend an Air Duct Inspection for any Timberwood Park home that hasn’t had ducts cleaned in three or more years, or if you’re noticing uneven airflow, musty odors when the AC kicks on, or allergy symptoms that spike during cedar season.
The inspection documents the condition of supply and return trunks, branch lines, and the blower compartment. In Timberwood Park’s climate, we frequently find condensation-related mold in attic ducts and fine yellow cedar dust packed into low return ducts where the air velocity drops.
Video Documentation
Our camera systems record color footage of your duct interior, timestamped and saved to a drive you keep. This matters for warranty claims, real estate transactions, and verifying that the cleaning was thorough. After our Air Duct Cleaning in Timberwood Park service, we run the camera again so you can see the difference.
Multi-Zone Assessment
Properties with two or more HVAC zones require separate inspection of each air handler and duct network. We map the system, identify which zones show the heaviest loading, and price cleaning per zone so you’re not paying for work on ducts that don’t need it.
Trusted Brands We Service in Timberwood Park
We clean and service ductwork connected to all major HVAC brands, and we stock filtration products from Honeywell, Aprilaire, and Guardsman for Timberwood Park customers who want upgraded media filters after cleaning. Our equipment roster includes Rotobrush rotary brush systems for agitation cleaning, Nikro negative-air machines for debris extraction, and Abatement Technologies HEPA filtration for containment. These are the same tools commercial crews use in hospitals and schools, not hardware-store shop vacs with brush attachments. If your system needs a filtration upgrade, we size it to your air handler’s specs and install it during the same visit.
Common Air Duct Cleaning Problems We See in Timberwood Park Homes
- Cedar pollen loading in returns. After January and February, Ashe juniper pollen settles as a fine yellow dust in low return ducts and blower compartments. Standard cleaning that only addresses supply vents misses this reservoir, so pollen recirculates as soon as the system runs.
- Condensation and mold in attic flexible ducts. Timberwood Park’s Gulf-influenced humidity and large attic temperature swings create condensation on flexible duct exteriors, which can lead to mold growth on the interior liner. We inspect for this during every job and clean with antimicrobial treatment where needed.
- Limestone dust infiltration from unpaved roads and open land. Thin rocky soils around Timberwood Park generate fine mineral dust that gets drawn into outdoor air intakes and settles in ductwork. This abrasive dust accelerates blower motor wear and reduces heat exchanger efficiency.
- Outbuilding systems recontaminating main house air. Detached workshops, barns, and guest houses with shared return air or independent air handlers often get skipped during cleaning, leaving a secondary pollen and dust reservoir that recirculates through the main house.

FAQs About Air Duct Cleaning in Timberwood Park
Most Timberwood Park homes need duct cleaning every 2 – 3 years, not annually, because the cedar pollen and limestone dust loading follows a distinct seasonal pattern rather than steady accumulation. Homes on unpaved roads, with multiple HVAC zones, or with outbuilding systems may need more frequent attention. Call (361) 326-5060 to discuss your property’s specific conditions.
The January – February Ashe juniper peak deposits fine yellow pollen deep into return ducts and blower compartments, and cleaning in late February or March removes this loading before spring oak pollen adds another layer. Summer or fall cleaning misses this window and leaves you breathing cedar residue through the cooling season. We schedule heavily in late February and March for this reason.
Yes. We clean multi-zone Timberwood Park properties regularly, adjusting our Rotobrush speed and negative-air vacuum strength to protect flexible attic ductwork while removing accumulated debris. Each zone is priced and cleaned as a separate system, with video inspection available for every air handler.
Yes. We clean detached workshop air handlers, guest house systems, and barn HVAC units that share return air with the main house or operate independently. Skipping these leaves a secondary dust and pollen reservoir that can recontaminate cleaned main-house ductwork. Pricing starts at $200 – $400 per outbuilding unit after inspection.
We inspect for soot and ash particle residue in return air ducts, then use rotary brush agitation under negative pressure to remove it along with cedar pollen and limestone dust. If combustion byproducts are present, we may recommend upgraded filtration with Honeywell or Aprilaire media filters to capture fine particles before they enter your living space. The 365-Day Done Right Promise covers all our cleaning work, including wood-heat systems.
