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.

Call us at (361) 326-5060 for a free written estimate.
We know Bellaire’s housing stock inside and out: the original 1950s-60s ranches on Braeburn Drive and Pine Street, the infill builds near Evergreen Park, the flooded-and-rebuilt properties off South Rice. These homes don’t have the ductwork of a new suburban development. They’ve got decades of modifications, retrofitted flex duct in hot attics, and pier-and-beam crawlspaces where Gulf Coast humidity never stops working. That matters because a crew that treats every house the same will miss the second system, skip the crawlspace returns, or quote one flat price and under-clean whatever they don’t have time for. We price per system, inspect with cameras, and document everything in writing.
Why Hollis Air Duct Cleaning Is Bellaire’s Preferred Air Duct Cleaning Company
Hollis Air Duct Cleaning operates under The Garrison Standard, which means written prices, written guarantees, and technicians who arrive inside the quoted window in uniform. We’ve built our reputation in Bellaire on jobs where the details matter: point-of-sale inspections with closing dates locked, flood-recovery work where multiple eras of repair hide in one attic, and older homes where three HVAC systems serve a single ranch.
Our 365-Day Done Right Promise covers every job in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit. No negotiation, no runaround.
Technicians are background-checked and uniformed; you’ll know who’s arriving before they knock. Phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops, no callback queues.
We coordinate scheduling from our Houston office, but our crews serve Bellaire locally and understand the specific pressures of this market: the City’s point-of-sale inspection program, the humidity-driven mold cycles, the post-flood rebuilds that leave debris in ductwork other cleaners never check.
Vent Cleaning in Bellaire
Vent Cleaning in Bellaire means more than brushing off a register cover. In these 1950s-60s ranches, supply vents often sit at the end of 30- to 40-foot flex duct runs that sag in attics where temperatures hit 140 degrees in July. The vents themselves collect the debris that makes it through: drywall dust from three renovations, pet dander, pollen that the Gulf Coast delivers ten months a year, and mold spores that thrive in Bellaire’s 75% average humidity. A proper vent cleaning removes the register, cleans the boot and first few feet of duct, and checks airflow with a manometer. In Bellaire, we typically charge $150 – $250 for vent cleaning as a standalone service, or include it in a full system cleaning.
When Registers Signal Deeper Problems
Black streaks around supply vents usually mean the duct behind them is leaking, pulling attic air and insulation through the gap. In Bellaire’s older ranches, we see this constantly: the original metal trunk lines are solid, but the flex duct connections have loosened over decades of thermal expansion. Cleaning the vent without sealing the leak just gives you a clean register and the same dirty air.
Kitchen and Bathroom Ventilation
Bellaire’s point-of-sale inspectors frequently flag exhaust ducts that terminate in attics instead of outside. We clean these runs, verify termination, and document the repair for closing. It’s a small job that kills a transaction if it’s missed.
Air Duct Repair in Bellaire
Air Duct Repair in Bellaire is often discovery work. You call for a cleaning and find crushed flex duct over a joist, a trunk line separated at the seam, or a return plenum rotted through from years of condensation. We quote repair separately from cleaning, in writing, before any work starts. Typical repairs in Bellaire run $200 – $500 for flex duct replacement, $400 – $800 for trunk line sealing or partial replacement, and $150 – $300 for return plenum repairs. We use mastic, not tape, on metal connections; mastic stays sealed where tape dries and fails in Bellaire’s attic heat.
Flood-Damage Assessment and Repair
After Harvey and subsequent heavy rain events, many Bellaire ranches were rebuilt with new drywall and flooring while the ductwork was left in place. We inspect with cameras and find water lines inside trunk lines, rusted collars, and flex duct that looks fine from the outside but collapses under agitation. We document everything for insurance or closing requirements.
Multi-System Coordination
The larger ranches near Evergreen Park and the newer infill homes often run two or three separate HVAC systems. We repair each system independently, price each in writing, and never assume that cleaning one trunk line means the others were touched. Per-system pricing protects you from the shortcut.
Trusted Brands We Service in Bellaire
Hollis Air Duct Cleaning works with professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, and stocks filtration products from Honeywell, Aprilaire, and Guardsman for Bellaire homeowners who want to maintain results after the cleaning. Our Rotobrush rotary brush systems agitate debris off duct walls without damaging the thin aluminum or flex duct common in Bellaire’s older homes. Nikro negative-air machines maintain HEPA-filtered suction during the entire job, so nothing escapes into your living space. We carry replacement flex duct, collars, and mastic on every truck, which means most repairs happen same-visit without a return trip that delays your closing or your comfort.
Common Air Duct Cleaning Problems We See in Bellaire Homes
- Standing condensation in low-point flex duct. Bellaire’s humid subtropical climate means attics stay moist eight or nine months a year. Flex duct sags over decades, creating low points where condensation pools and mold colonizes. We find this on camera inspections in roughly half the 1950s-60s ranches we service.
- Crushed or pinched flex duct over joists. Original installers ran flex duct across joist bays without proper support. In the heat, the duct softens and compresses, cutting airflow by 30% or more. We replace these sections with properly supported new flex and document the before-and-after airflow.
- Crawlspace returns contaminated with flood debris. Pier-and-beam homes on South Braeswood and nearby streets have return plenums and duct runs in crawlspaces that took water during Harvey and subsequent floods. The debris dries, the humidity returns, and the system recirculates whatever’s down there. We inspect these with remote cameras and clean or replace as needed.
- Multiple undocumented HVAC systems in one attic. Flood rebuilds and additions often mean a second or third system was added without updating the original duct layout. We map every trunk line, identify every system, and price per unit so nothing gets skipped.

FAQs About Air Duct Cleaning in Bellaire
Yes, the City’s point-of-sale inspection program can require duct cleaning or repair as a condition of closing, particularly when inspectors find visible mold, debris, or disconnected ductwork. We work directly with realtors and buyers to complete the work, provide before-and-after documentation, and meet the closing timeline. Call (361) 326-5060 if you have an inspection deadline.
Per-system pricing prevents under-cleaning. A crew that quotes one flat price for the whole house will often run out of time and skip the third system or half-clean the second. We price each system separately, clean each one completely, and document each independently. You’ll know exactly what was done and what it cost before we start.
Bellaire’s average humidity stays above 70% for most of the year, and attic temperatures exceed 130 degrees in summer. That combination creates constant condensation inside metal trunk lines and flex duct low points. Mold colonizes within 24-48 hours of moisture exposure, and the HVAC system distributes spores throughout the house. We find active mold in roughly half the older ranches we inspect, and we clean with HEPA-contained negative air to prevent cross-contamination.
Yes. Many Bellaire homes were rebuilt after Harvey and subsequent floods with new interiors but original ductwork. Water lines inside trunk lines, sediment in low points, and rusted metal components are common. We inspect with cameras, document findings, and clean or replace as needed. This is especially critical for point-of-sale inspections where the buyer needs proof the system is clean.
You should receive a written invoice listing each system cleaned, any repairs made, before-and-after photos or video from the camera inspection, and the technician’s notes on duct condition. For point-of-sale jobs, we provide a summary letter suitable for the realtor and inspector. This documentation protects you at closing and validates the 365-Day Done Right Promise. Call (361) 326-5060 to schedule a documented cleaning.
