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 Lochearn long enough to know the houses. The 1950s brick ranches along Liberty Road. The split-levels off Milford Mill Road. The two-story colonials near the county line with full basements nobody’s been in for years. These homes weren’t built for modern HVAC loads, and their ductwork is telling that story. We find crushed flex runs, disintegrating fiberglass wrap, and masonry return chases still holding coal-dust residue from the heating era before natural gas. Our job is to clean what’s dirty and show you what’s broken, so you’re not paying to move air through ducts that leak half their volume into your crawlspace.
Why Hollis Air Duct Cleaning Is Lochearn’s Preferred Air Duct Cleaning Company
We’ve been part of the Garrison Partners family since 2004, and our Air Duct Cleaning crews have worked Lochearn homes enough to recognize the neighborhood’s specific failure patterns before we pull the first register. Roy Castellanos leads this operation, and The Garrison Standard he follows means written prices, written guarantees, and technicians who arrive inside the quoted window, not “sometime between 8 and 5.”
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. Background-checked, uniformed technicians. Phones answered by a live person 24 hours a day, 7 days a week. The price we write down before work starts is the price you pay. We’ve seen what happens when Lochearn homeowners get a low teaser quote that doubles once the van is in the driveway. We don’t work that way.
Air Duct Repair in Lochearn
Air Duct Repair in Lochearn is rarely a standalone call. Usually we find it during a cleaning: a crushed flex branch behind a finished basement wall, a galvanized trunk rusted through where condensation collected in the basement loop, or a supply run disconnected entirely and blowing conditioned air into an unconditioned attic. Typical repairs in Lochearn run $200 – $500 for individual runs, with full trunk replacement on a ranch-style home reaching $1,200 – $2,800 depending on access and material.
Crushed and Disconnected Flex Runs
The flex duct retrofitted into Lochearn’s 1960s and 1970s homes was never meant to last 50 years. We regularly find it flattened behind walls, chewed by rodents in crawlspaces, or pulled loose at the collar. A camera inspection finds it. A written quote fixes it. No surprises.
Coal-Dust Residue in Masonry Chases
Those basement return-air chases built into the original masonry? They’re not standard ductwork. Standard vacuuming won’t source-remove the compacted coal soot. We use agitation tools and negative-air HEPA extraction, then perform Duct Sealing - Lochearn on the chase properly so it stops pulling from unconditioned space.
Ductwork Cleaning in Lochearn
Ductwork Cleaning in Lochearn means more than brushing out supply lines. The full system includes returns, trunk lines, the air handler cabinet, and the coils. For a typical Lochearn ranch or split-level, complete residential ductwork cleaning runs $350 – $650. Commercial systems start around $800 and scale with square footage and access complexity. We use Rotobrush rotary brush systems for mechanical agitation and Nikro negative-air machines to maintain containment, so debris isn’t redistributed through your home during the job.
Source Removal vs. Surface Cleaning
Source removal is the NADCA standard we follow. It means the contamination leaves the building, not just gets loosened. Our HEPA-filtered negative-air machines create suction at 2,000+ CFM while brushes or compressed-air whips dislodge buildup. What comes loose gets captured and filtered, not pushed out your registers.
Coil and Cabinet Cleaning
The air handler in your basement or closet collects what the ducts deliver. If we clean the ducts but leave a moldy coil or dust-caked blower, the system recontaminates itself in weeks. Coil cleaning is included in our full-system pricing, not sold as an upsell.
Trusted Brands We Service in Lochearn
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation inside duct walls, Nikro negative-air machines for containment and extraction, and filtration products from Honeywell, Aprilaire, and Guardsman. We don’t use hardware-store shop vacs on Lochearn’s aging galvanized steel and masonry chases. The tools matter because the housing stock here demands it. A Rotobrush head can navigate the tight turns in a 1950s ranch retrofit where a standard vacuum hose won’t reach. Nikro’s HEPA filtration keeps coal-dust particulate from settling back into your living space during the job. We stock common fittings and flex duct sizes for Lochearn’s dominant housing types, so repairs don’t wait on a parts run.
Common Air Duct Cleaning Problems We See in Lochearn Homes
- Coal-dust residue misidentified as mold. The gray-black soot in basement masonry chases along Liberty Road is often old coal dust, not microbial growth. Antimicrobial spray won’t remove it. Source removal with agitation tools will.
- Disintegrating fiberglass duct wrap leaking into attics and crawlspaces. That white or yellow dust around your basement trunk? It’s the original insulation breaking down. The duct underneath may be intact, but the thermal and air barrier is gone, driving up bills and pulling unconditioned air into the system.
- Crushed flex duct behind finished walls. Rooms that never cool evenly often trace back to a flex branch flattened during a basement renovation decades ago. We find it with camera inspection and fix it with minimal disruption.
- Humidity-driven mold on coils and in basement returns. Lochearn’s sticky summers and damp basement environments create ideal conditions for coil mold. Cleaning the ducts without addressing the coil means the smell and spores return within weeks.

FAQs About Air Duct Cleaning in Lochearn
It’s probably coal-dust residue from the neighborhood’s original heating era, not mold. The masonry return chases in Lochearn’s Liberty Road corridor homes were built for coal furnaces, and that gray-black soot compacts into porous brick and mortar where standard vacuuming can’t reach it. We source-remove it with agitation tools and negative-air HEPA extraction, then seal the chase so it stops pulling from unconditioned space. Call (361) 326-5060 if you want us to inspect it.
Usually yes. The original galvanized steel and early flex duct in these homes has reached the end of its design life. We regularly find disconnected runs, crushed flex behind finished walls, and disintegrating fiberglass wrap during what the homeowner thought was a routine cleaning. We write separate prices for cleaning and repair, and you choose what to proceed with. No package deals, no pressure.
Lochearn’s humid subtropical climate means heavy AC use from May through September, with shoulder seasons that pull pollen and mold spores through open windows into return ducts. Most Lochearn homes benefit from full-system cleaning every 3 – 5 years, with coil cleaning every 2 – 3 years if you run AC continuously. Homes with basement moisture issues or visible mold may need more frequent attention.
NADCA requires source removal of contaminants, protection of the home and HVAC components during cleaning, and verification of results. For our Lochearn jobs, that means negative-air containment, mechanical agitation with rotary brushes or compressed-air tools, HEPA filtration on all exhaust, and post-cleaning inspection with a camera. We don’t consider a job complete until we can show you the before and after.
Yes. Crushed or disconnected flex duct is one of the most common causes of uneven cooling in Lochearn’s ranch and split-level homes. The flex was often routed through tight crawlspaces or behind basement walls where it gets flattened by settling, renovation, or rodent activity. We verify airflow at each register and camera-inspect suspect runs. Repair is usually straightforward once we locate the damage. Call (361) 326-5060 to schedule a diagnostic.
