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 been working in the Canyon Lake area long enough to know the local pattern: when the reservoir drops below 890 feet, the dried limestone shoreline along Canyon Lake Shores and North Shore puts a fine white dust into the air that finds its way straight into ductwork. Combine that with the humidity spikes during fall and spring flood cycles, and you’ve got a system that loads up faster than ducts in nearby New Braunfels or San Marcos. Our Air Duct Cleaning team handles everything from 1970s lake cabins with crawlspace flex duct to newer hill-country custom homes with multiple returns and heat pumps. We bring Rotobrush rotary systems and Nikro negative-air machines to every job, and every Hollis technician works under The Garrison Standard: arrive inside the window, price in writing, finish by the book, leave the site clean.
Why Hollis Air Duct Cleaning Is Canyon Lake’s Preferred Air Duct Cleaning Company
Hollis has been part of the Garrison Partners family since 2004, and our crews know the Canyon Lake market well enough to spot the difference between ordinary household dust and the limestone grit that shows up during low-water periods. We’ve cleaned ducts in the original 1970s cabins off Startzville Road, in the newer builds around Hancock, and in the lakefront properties along Canyon Lake Shores where the dust loading is heaviest.
Our technicians are background-checked and uniformed, and 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 a job in Canyon Lake, you get a written price before any work starts, and that price does not move when the crew arrives. Every job carries our 365-Day Done Right Promise: if the work fails within a year, we come back and make it right at no charge, including a free second visit. That’s written on every invoice, not mentioned verbally and forgotten.
We don’t compete on teaser coupons or per-vent pricing that balloons at the door. We compete on discipline. Roy Castellanos runs Hollis Air Duct Cleaning under The Garrison Code, and that means predictable pricing, accountable crews, and a standard that doesn’t change because your property is harder to reach or your system is older than expected.
Commercial Air Duct Cleaning in Canyon Lake
Commercial Air Duct Cleaning in Canyon Lake covers the same limestone-dust and humidity challenges as residential work, but at larger scale: restaurants, retail, office suites, and rental properties around the lake that see heavier occupancy and more frequent HVAC cycles. A typical commercial duct cleaning in Canyon Lake runs $800 – $2,500 depending on square footage, system count, and access difficulty. We use Nikro negative-air machines and HEPA filtration to contain dust during the cleaning, not blow it back into your space.
Restaurant and Retail Systems
Grease-laden vent hoods and high-occupancy spaces around the Canyon Lake marina district load up faster than standard office systems. We clean supply and return ductwork, inspect the air handler, and document the work with before-and-after photos you can keep for your records.
Rental and Multi-Unit Properties
Turnover cleaning between tenants often reveals filters that haven’t been changed in years and ducts packed with accumulated debris. We price per system, not per vent, so your invoice matches the quote you approved before we started.
Air Duct Cleaning Services in Canyon Lake
Air Duct Cleaning Services in Canyon Lake address a specific regional cycle: the reservoir’s water level swings create alternating dust and dampness problems that don’t exist in the same way even fifteen miles away in New Braunfels. A typical full residential system cleaning in Canyon Lake costs $350 – $650, with dryer vent add-ons at $120 – $180 and duct sealing work quoted separately after inspection. We don’t guess at your price over the phone; we inspect, write it down, and get your approval before opening any equipment.
Residential Full System Cleaning
Our standard residential job covers all supply and return ducts, the air handler cabinet, and the blower assembly. On older Canyon Lake cabins with crawlspace flex duct, we inspect the trunk connections for leaks that pull in unconditioned air and reload the system with dust.

Video Inspection and Documentation
We run camera footage through your ducts before and after cleaning, especially on properties where the white limestone dust has built up in layers. You see what we see. No trust required.

Trusted Brands We Service in Canyon Lake
Hollis carries professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, and we stock filtration products from Honeywell, Aprilaire, and Guardsman for Canyon Lake customers who need replacement media after a cleaning. The Rotobrush rotary brush system scrubs duct walls without damaging older flex duct common in 1980s lake cabins, while Nikro negative-air machines maintain containment so we’re not redepositing limestone grit into your living space. We size replacement filters to your actual system, not to whatever’s on the van that day. If your Canyon Lake home runs a heat pump with a media cabinet rated for MERV 11, that’s what we install. No upsell to a filter your blower can’t handle.
Common Air Duct Cleaning Problems We See in Canyon Lake Homes
- Limestone dust infiltration during low reservoir levels. When Canyon Lake drops below 890 feet, the exposed shoreline dries and sends fine white grit airborne. Homes near Canyon Lake Shores and North Shore see register buildup that looks like construction dust but is actually geological. Standard vacuums without HEPA filtration and negative pressure just re-suspend it.
- Mold and mildew in crawlspace and attic duct runs. The fall and spring flood cycles push humidity into unconditioned spaces where poorly sealed original ductwork from the 1970s and 1980s sweats and grows microbial contamination. We inspect these runs with cameras and clean or recommend replacement based on what we find.
- Heat pump systems running constantly in summer. Canyon Lake’s humid subtropical climate means heat pumps work overtime July through September, moving more air and loading filters faster. Older cabins with original duct sizing often have blowers straining against restricted airflow.
- Leaking trunk connections in unconditioned attics and crawlspaces. Many Canyon Lake properties pull conditioned air into spaces that reach 140 degrees in summer or flood with groundwater in spring. We seal with mastic after cleaning so the system doesn’t immediately re-contaminate.
Pricing for Air Duct Cleaning in Canyon Lake, TX
A full residential Air Duct Cleaning in Canyon Lake typically costs $350 – $650 for a single system up to about 2,500 square feet. Larger homes, multiple systems, or properties with extensive crawlspace ductwork run $650 – $950. Commercial jobs start around $800 and scale with square footage and access difficulty. Dryer vent cleaning adds $120 – $180. Duct sealing is priced after inspection, since we need to see how much of your trunk is accessible and how badly it’s leaking.
What moves the price: system size, number of returns, crawlspace versus attic access, and whether we find mold that requires antimicrobial treatment. We do not quote per-vent. We quote per system, in writing, before work starts. The price you approve is the price on the invoice. Call (361) 326-5060 for a free estimate at your Canyon Lake property.

FAQs About Air Duct Cleaning in Canyon Lake
Canyon Lake’s reservoir-level swings create a dust-and-dampness cycle that doesn’t hit inland cities the same way. When the lake drops below 890 feet, dried shoreline limestone becomes airborne grit that loads ductwork faster than typical household dust, and the fall/spring flood cycles push humidity into crawlspace ducts that promotes mold growth. Most Canyon Lake properties we serve benefit from cleaning every 2 – 3 years rather than the 4 – 5 year interval common in New Braunfels. Call (361) 326-5060 and we’ll inspect your system and recommend a schedule based on your location and HVAC setup.
Every 2 – 3 years for most crawlspace cabins in Canyon Lake, and sometimes more frequently if you’re downwind of the reservoir during a low-water period. Crawlspace flex duct from the 1970s – 1990s era leaks heavily into unconditioned space, pulling in dust and groundwater vapor that reloads the system continuously. We inspect trunk connections and seal leaks during cleaning so you’re not paying for the same work on shortened intervals. Call (361) 326-5060 for a free inspection and written recommendation.
Yes. We clean ductwork in detached shops, guest houses, and outbuildings with independent systems, priced separately from the main house. Rural properties around Canyon Lake often have wood heat or older heat pumps in these buildings with minimal filtration and heavy dust loading from unpaved driveways and open land. We price each system in writing before starting, same as the main house. Call (361) 326-5060 to schedule a walkthrough of all your structures.
It’s most likely limestone grit from the reservoir shoreline, not construction dust or ordinary household debris. When Canyon Lake drops below 890 feet, the exposed white limestone along Canyon Lake Shores and North Shore dries and pulverizes into fine particles that your HVAC system pulls in through return leaks and gaps around the air handler. We pulled the flex supply and return ducts out of a 1980s lake cabin off Canyon Lake Shores during a low-water stretch and found the interior liner coated in the same fine white limestone grit that was hazing the neighborhood – the homeowner assumed it was construction dust from a nearby build. After a camera inspection of the air handler, we ran agitation tools and negative pressure with HEPA filtration to the exterior, then sealed the leaking trunk in the crawlspace and swapped the filter to a properly sized MERV rating so the next drawdown wouldn’t reload the system. Call (361) 326-5060 if you’re seeing this pattern; we’ll confirm the source and fix the entry points.
Yes. Wood heat produces fine ash and creosote particulate that accumulates in ductwork differently than standard dust, and older heat pumps often run longer cycles with lower airflow, which deposits more debris in the coils and blower. On Canyon Lake hill-country homes with both systems, we inspect the heat pump cabinet and blower more closely and may recommend more frequent filter changes between cleanings. The cleaning scope itself – full duct agitation, negative-air HEPA containment, and trunk sealing – remains the same, but we adjust our inspection focus based on what equipment you’re running. Call (361) 326-5060 and we’ll tailor the work to your actual system mix.
