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.
Fast, Reliable Air Duct Cleaning Across Sandy Oaks
Air duct cleaning in Sandy Oaks typically runs $350 – $650 for a full residential system, with most jobs completed in a single visit. If you’re noticing dust settling on furniture within a day of cleaning, or your HVAC blower seems to strain harder each season, your ductwork is likely carrying more than it should.
We serve Sandy Oaks from our Dallas-Fort Worth dispatch office, with crews routed specifically for this south Texas market. Roy Castellanos and our team have worked enough homes near the intersection of Highway 281 and Evans Road to know what the caliche dust out here does to return-air systems. Long duct runs in unconditioned attics are common in Sandy Oaks, and that combination of heat, humidity, and fine particulates wears on equipment faster than homeowners expect. When you’re ready to see what’s actually inside your ducts, call us at (361) 326-5060. We’ll give you a written price before any work starts, and we back every job with our 365-Day Done Right Promise.
Why Hollis Air Duct Cleaning Is Sandy Oaks’s Preferred Air Duct Cleaning Company
Hollis Air Duct Cleaning has been part of the Garrison Partners family since 2004. That track record matters in a market like Sandy Oaks, where many competitors arrived more recently and operate without a written guarantee behind their work. We’re not a franchise template; each Hollis location is independently owned and operated under The Garrison Standard, which means our technicians arrive inside the quoted window, price the job in writing before touching equipment, and leave the site clean.
Our phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues. When you schedule in Sandy Oaks, you get a background-checked, uniformed technician who has been briefed on the local conditions: the manufactured housing near Southton Road, the custom builds off Blue Wing Road, the older single-family stock closer to the San Antonio city limits. Each presents different duct configurations, and our crew shows up prepared.
The 365-Day Done Right Promise applies to every job we do in Sandy Oaks. If the work fails within a year, we return and make it right at no charge, including a free second visit. That promise is backed in writing on every invoice, not offered verbally and forgotten later.
Commercial Air Duct Cleaning in Sandy Oaks
Commercial Air Duct Cleaning in Sandy Oaks covers office buildings, light industrial spaces, and multi-tenant properties where HVAC systems run continuously through the long cooling season. A typical commercial system in this market runs $800 – $2,400 depending on square footage, duct complexity, and whether video inspection reveals buildup beyond what standard access points can reach. Properties near active oil and gas operations face accelerated particulate loading, so we assess blower motor condition and filter media separately from duct trunk lines.
System Assessment and Access Planning
We start with a walkthrough to locate all supply and return points, then determine whether rotary brush or negative-air methods suit the duct material. Older metal trunk systems common in Sandy Oaks commercial buildings from the 1980s and 1990s tolerate aggressive mechanical cleaning; newer flex duct requires adjusted pressure settings.
Post-Cleaning Verification
After cleaning, we run a video inspection through key trunk sections and provide the footage to the property manager. This documentation supports maintenance records and confirms the work was completed to specification before we leave the site.
Air Duct Cleaning Services in Sandy Oaks
Air Duct Cleaning Services in Sandy Oaks address the specific burden this region places on residential HVAC systems. A full residential cleaning typically costs $350 – $650, with return-only or supply-only cleaning available in the $180 – $320 range for partial system maintenance. Homes with long attic duct runs, common in Sandy Oaks’s rural lots, often need more attention at the air handler and return plenum than at distant supply registers.
Whole-System Cleaning and Inspection
We clean supply ducts, return ducts, and the air handler cabinet as one integrated system. Splitting the job creates pressure imbalances and leaves debris that simply recirculates. Our Air Duct Cleaning team uses Rotobrush rotary systems for mechanical agitation and Nikro negative-air machines to capture dislodged material before it enters your living space.

Targeted Return and Supply Line Maintenance
For homeowners who maintain their systems regularly, we offer focused cleaning of either return or supply lines. This is useful after construction, during pollen season, or when one wing of the house shows uneven airflow. We also handle Dryer Vent Cleaning in Sandy Oaks and Duct Sealing in Sandy Oaks on the same visit when scheduling allows.

Trusted Brands We Service in Sandy Oaks
Our equipment roster includes Rotobrush rotary brush systems for mechanical duct cleaning, Nikro negative-air machines for containment and extraction, and filtration products from Honeywell, Aprilaire, and Guardsman. We stock common filter sizes and replacement media for Sandy Oaks customers, which means faster turnaround when your system needs more than just cleaning. If your air handler uses a proprietary Aprilaire media cabinet or a Guardsman MERV-rated upgrade, we carry those specifications and install them at the time of service rather than ordering and returning later. The same applies to Abatement Technologies HEPA filtration add-ons for homeowners with allergy or respiratory concerns. We don’t sell equipment you don’t need; we match the tool to the condition of your ductwork and explain why in plain terms before any work starts.
Common Air Duct Cleaning Problems We See in Sandy Oaks Homes
- Caliche dust infiltration through return registers. After dry, windy days, our technicians regularly find a visible layer of fine powder inside supply registers on the south and west sides of Sandy Oaks homes. This material migrates from the Eagle Ford Shale environment directly into your blower motor and evaporator coil, reducing efficiency and accelerating wear.
- Microbial growth in long attic duct runs. The humid subtropical climate here keeps attic temperatures above dew point for months at a time. Flexible ductwork in unconditioned spaces develops condensation on the exterior, which wicks into insulation and creates conditions for odor and biological buildup at joints and seams.
- Undersized filters in older manufactured housing. Many Sandy Oaks homes built in the 1990s and early 2000s use 1-inch filter slots that clog quickly during pollen season. Homeowners who upgrade to higher-MERV media without adjusting fan speed strain the system and increase static pressure, which pulls more unfiltered air through gaps in the return plenum.
- Deteriorated duct sealing at trunk connections. Temperature cycling in Sandy Oaks attics, where summer peaks exceed 140°F, hardens mastic and separates tape bonds. Conditioned air leaks into the attic before reaching living spaces, which homeowners often mistake for a need for more insulation rather than duct sealing.
Pricing for Air Duct Cleaning in Sandy Oaks, TX
A typical full residential air duct cleaning in Sandy Oaks runs $350 – $650 for a standard single-system home. Return-only cleaning runs $180 – $320; supply-only cleaning falls in the same range. Commercial systems start around $800 and scale with square footage, duct accessibility, and whether video inspection reveals conditions requiring additional access points or specialized containment.
What moves the price: the number of HVAC zones, the length of duct runs (common in Sandy Oaks’s large-lot properties), whether your system uses hard duct or flex duct, and the condition of the air handler cabinet. We do not price per vent. One flat price per system, agreed in writing before work starts. No surprise add-ons once the van is in your driveway.
