Call (361) 326-5060

We’re Hollis Air Duct Cleaning, and we’ve been working in the San Antonio metro since 2004. Our crews know Terrell Hills well, from the winding streets near Morningside Drive to the larger lots off Mount Vernon Drive and the custom builds clustered near the country club. Because this city operates its own permitting and code enforcement, separate from San Antonio or Bexar County, we coordinate directly with Terrell Hills’s building inspection department when a job requires it. That local knowledge keeps your job moving without delays. Call us at (361) 326-5060 for a free estimate.

Why Hollis Air Duct Cleaning Is Terrell Hills’s Preferred Air Duct Cleaning Company

Terrell Hills homeowners don’t call us because we’re the cheapest. They call because they’re tired of estimates that balloon once the truck is in the driveway. Our written price policy means the number you agree to before we start is the number on the invoice. No per-vent add-ons, no “discovered problems” that double the bill.

Our technicians arrive uniformed and background-checked, following The Garrison Code on every job: show up inside the quoted window, price it in writing, complete the work by the book, and leave the site clean. Roy Castellanos, who leads Hollis Air Duct Cleaning, built this operation on the understanding that a homeowner should never have to guess who’s entering their house or whether the work will hold up.

Dispatch and scheduling for Terrell Hills run through our San Antonio office, so we’re not routing calls through a distant call center. A live person answers the phone 24 hours a day, 7 days a week. If you’ve got a question about your ductwork at 9 p.m. on a Saturday, you’ll talk to someone who can actually help.

Every job carries our 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 put that in writing on every invoice.

Air Duct Cleaning Services in Terrell Hills

Air Duct Cleaning Services in Terrell Hills cover the full network of supply and return ducts, registers, grilles, and the main trunk lines that move conditioned air through your home. In Terrell Hills, where many houses are mid-century to late-20th-century custom ranches with full attics and original flexible duct runs, we regularly find systems that have never been properly cleaned since installation. A typical residential full-system cleaning in Terrell Hills runs $350 – $650, depending on the number of air handlers, the accessibility of attic runs, and whether we find significant contamination requiring extra passes with our rotary brush system.

We use Rotobrush rotary brush systems and Nikro negative-air machines, the same equipment commercial crews rely on. The rotary brush scrubs the interior duct walls while the negative-air machine pulls dislodged debris out of your home entirely, rather than redistributing it. For filtration upgrades, we stock Honeywell, Aprilaire, and Guardsman products sized for the larger square footage common in Terrell Hills homes.

Residential Duct Cleaning

Most Terrell Hills homes we service fall between 2,500 and 5,000 square feet with duct networks that snake through attics and crawl spaces. Our residential cleaning includes all accessible supply and return ducts, the main trunk, and each register cover. We also photograph the interior before and after so you see what came out.

Commercial Duct Cleaning

Terrell Hills’s commercial buildings, including professional offices along Broadway and smaller retail spaces, require scheduled cleanings that minimize disruption. We coordinate with property managers to work after hours or weekends, using containment procedures that keep your space operational.

HVAC Duct Cleaning in Terrell Hills

HVAC Duct Cleaning in Terrell Hills addresses the entire heating, ventilation, and air conditioning pathway, not just the visible vents. Because South Texas heat and humidity push your system to run almost year-round, Terrell Hills ducts accumulate dust, pollen, and biological growth faster than in milder climates. The high humidity can also cause condensation inside ductwork, especially where flexible runs sag or returns leak, creating conditions for mold that recirculates through your living spaces. A typical HVAC duct cleaning in Terrell Hills runs $400 – $750 for systems with multiple zones or hard-to-access attic components.

Our process starts with a video inspection when the layout is complex or the homeowner suspects specific problem areas. We feed a camera through the ductwork to locate blockages, collapsed flexible runs, or moisture damage before we quote the full scope. This prevents surprises and lets us show you exactly what we’re dealing with.

Video Inspection and Assessment

Many Terrell Hills homes have never had their ducts inspected internally. Our video inspection identifies collapsed flexible ducts, disconnected joints, and biological growth that wouldn’t be visible from the register. You’ll see the footage, and we’ll explain what it means for your air quality and energy bills.

Full System Cleaning and Sealing

After cleaning, we evaluate whether your ducts need sealing. Leaky returns pull attic air into your system, and leaky supplies waste conditioned air into crawl spaces. We also handle Duct Sealing in Terrell Hills when testing shows significant leakage.

Trusted Brands We Service in Terrell Hills

We clean and service ductwork connected to all major HVAC brands, and we stock filtration products from Honeywell, Aprilaire, and Guardsman for same-day replacement when your system needs an upgrade. Our equipment roster includes Rotobrush rotary brush systems for mechanical scrubbing and Nikro negative-air machines for debris extraction, both sized for the larger duct networks typical of Terrell Hills homes. If your system uses specialized filtration media or electronic air cleaners, we carry compatible replacements and can advise on upgrades that match your equipment without overselling. Most filter swaps and minor component replacements happen during the same visit as your cleaning, so you’re not scheduling a second trip.

Common Air Duct Cleaning Problems We See in Terrell Hills Homes

• Original flexible ductwork sagging in attics. Many Terrell Hills homes built between the 1950s and 1980s still have flexible duct runs that have sagged over decades, creating low spots where dust and moisture collect. These sagging sections restrict airflow and become breeding grounds for biological growth.
• Poorly sealed returns pulling attic air. Custom-built homes of this era often have return plenums and duct joints sealed with cloth-backed tape that has dried and failed. Your system ends up filtering hot, dusty attic air instead of recirculating clean indoor air.
• Condensation inside ductwork from humidity. Terrell Hills’s shaded lots and mature tree canopy slow attic drying after cleaning or during humid periods. When ducts aren’t properly insulated or sealed, condensation forms on cool metal surfaces and supports mold growth.
• Extensive duct networks with multiple zones. Larger Terrell Hills homes frequently have 3 – 4 separate air handlers or zoning systems that each need individual attention. Partial cleaning of one zone leaves contamination circulating through the others.
