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’ve worked in Conroe long enough to know the difference between a Loop 336 subdivision built in 2018 and a 1970s ranch on county land. The duct systems aren’t the same. The problems aren’t the same. And a crew that treats them the same will miss half the job.
Why Hollis Air Duct Cleaning Is Conroe’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family. That’s a track record that predates most of the duct cleaning outfits you’ll find in Montgomery County today. Our Conroe customers know our technicians arrive uniformed, background-checked, and inside the quoted window – because The Garrison Standard says we do, and we put it in writing.
Our phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday to schedule. When you call (361) 326-5060, you talk to a human who can book your Conroe appointment and give you a real arrival window.
Every job gets a written price before we touch anything. The price does not move at the door. And every repair or cleaning is backed by 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.
Air Duct Cleaning Services in Conroe
Air Duct Cleaning Services in Conroe cover the complete removal of dust, pollen, mold spores, and construction debris from your supply and return ductwork using professional-grade equipment. A typical residential cleaning in Conroe runs $350 – $550 for a standard single-system home, while larger homes or properties with multiple air handlers range $500 – $650. Most Conroe homeowners need this service every 2 – 3 years, though rural properties on unpaved roads often need shorter intervals due to heavier grit loading.
Residential Duct Cleaning
We clean the full supply and return network in your home, from the main trunk lines to the branch ducts at each register. In Conroe’s post-2010 subdivisions, we often find flexible ductwork in attics that needs careful handling to protect builder warranties. Our rotary brush systems agitate debris without damaging thin-walled flex duct.

Commercial and Outbuilding Systems
Shops, barns, and converted outbuildings on Conroe acreage frequently run separate air handlers that collect wood ash, pollen, and road grit. We treat these as distinct systems with their own cleaning scope and pricing, typically $200 – $400 per additional air handler.

HVAC Duct Cleaning in Conroe
HVAC Duct Cleaning in Conroe addresses the entire forced-air system, including the air handler, coils, and registers, not just the visible duct runs. In Conroe’s humid subtropical climate, this matters more than in drier regions – your system runs hard eight months a year, pulling in pine pollen, mold spores, and dust that accumulate rapidly. A full HVAC duct cleaning in Conroe typically costs $450 – $650 and includes before-and-after video inspection so you see what came out.
Video Inspection and Documentation
We camera-inspect your ducts before and after cleaning. You see the buildup. You see the clean. In Conroe, we regularly show homeowners mold growth in attic trunk lines they didn’t know existed – the source of that musty AC smell they’ve been masking with air fresheners.
Negative-Air Method with HEPA Filtration
Our Nikro negative-air machines pull debris out of your ductwork under controlled suction, capturing it in HEPA filtration rather than letting it settle back into your home. This is the same method commercial crews use in hospitals and schools. We explain how it works in plain terms before we start.
Trusted Brands We Service in Conroe
We clean and service duct systems connected to all major HVAC brands, and we stock filtration products from Honeywell, Aprilaire, and Guardsman for Conroe customers who want upgraded protection after their cleaning. Our equipment roster includes Rotobrush rotary brush systems and Nikro negative-air machines – professional-grade tools, not hardware-store gear. If your Conroe home needs new filtration media or a UV light upgrade after cleaning, we carry the parts and install them the same visit. No waiting on shipped orders, no return trips.
Common Air Duct Cleaning Problems We See in Conroe Homes
- Pine pollen and road grit overload in rural properties. Homes on unpaved county roads around Conroe load return ducts with a coarse grit that standard filters can’t catch. We see filters clogged solid after six weeks instead of three months.
- Mold in attic trunk lines of slab-foundation homes. Conroe’s 100°F+ attic temperatures combined with high humidity degrade duct insulation and cause condensation. The musty AC smell homeowners report is often active mold growth, not just dust.
- Detached shops and outbuildings with forgotten air handlers. The main house gets cleaned, but the shop system keeps recirculating wood ash and pollen. We address these as separate systems with their own scope.
- Construction debris in newer Loop 336 subdivisions. Post-2010 Conroe builds often have drywall dust, wood scraps, and insulation scraps left in ductwork during construction. Builder-grade filters don’t remove what’s already inside.

FAQs About Air Duct Cleaning in Conroe
Every 18 – 24 months, not the standard 3 – 5 years. The combination of pine pollen, road grit, and wood heat loads filters and return ducts faster than suburban homes on paved streets. If you’re changing filters monthly and still seeing dust buildup, your ducts are likely packed. Call (361) 326-5060 and we’ll camera-inspect to tell you for certain.
Yes. We treat outbuilding systems as separate jobs with their own scope and pricing, typically $200 – $400. The shop air handler pulls the same pollen and grit as your main house, plus wood ash if you heat with a stove. Cleaning only the main house leaves a contamination source running continuously. We can schedule both systems the same day.
Mold growth in attic trunk lines, caused by degraded duct insulation and condensation in 100°F+ attic temperatures. The high humidity in Conroe’s climate lets mold colonize quickly once insulation fails. Surface dust removal won’t fix it – we address the mold source directly and show you before-and-after video. Call (361) 326-5060 if you’re smelling musty air from your vents.
Yes. The equipment and method don’t change because of mileage. We bring Nikro negative-air machines, HEPA filtration, and Rotobrush agitation tools to every Conroe job, whether it’s a Loop 336 subdivision or a 20-acre property past the city limits. The Garrison Standard applies everywhere we work.
They’re separate systems, but we clean both. Dryer vent cleaning removes lint buildup that creates fire risk and extends drying times. If we’re already on site for duct cleaning, we can inspect and quote your dryer vent the same visit. Many Conroe homeowners bundle the two jobs.
