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.

Lakeland South isn’t like the cities to the north. Most homes here are 1970s – 1990s ranch-style builds on private wells or septic, with air handlers mounted in crawlspaces instead of attics. That matters for duct cleaning. Duct runs laid on damp soil, original flex duct that’s never been serviced, and rodent pressure every fall – these aren’t hypotheticals here. They’re what our technicians find on most Lakeland South jobs. Our Air Duct Cleaning team knows the difference between a crawlspace trunkline and an attic drop, and we price by the system so you’re not paying per vent for three separate HVAC setups.
Why Hollis Air Duct Cleaning Is Lakeland South’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Lakeland South on showing up when we said we would, pricing in writing before we touch anything, and leaving the site clean. The Garrison Standard requires it. Every technician is 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.
Our 365-Day Done Right Promise covers every job in writing. If the work fails within a year, we come back at no charge, including a free second visit. That’s not a satisfaction guarantee – it’s a specific, written commitment that competitors in this trade rarely match.
Dispatch and scheduling for Lakeland South are coordinated from our Seattle office, but the crews that arrive at your door are local to South King County. They know the area. They know which homes off Military Road have crawlspace access limited by grade, and they know that a musty smell in a Lakeland South hallway in February usually means standing water in a sagging flex duct run, not a dirty filter.
Air Duct Inspection in Lakeland South
Air Duct Inspection in Lakeland South is the first step for any homeowner who smells musty air, sees uneven heating, or suspects rodents have been in the crawlspace. We run a camera through the full duct network, check the air handler cabinet, and document what we find with photos you can see on a tablet before we quote any cleaning work. A typical inspection in Lakeland South runs $150 – $250, and that fee is credited toward your cleaning if you move forward.
Camera Documentation for Crawlspace Systems
Most Lakeland South homes have duct runs you can’t see without crawling through mud. Our camera inspection gives you eyes on every trunkline, every sag, every chew mark. We show you the footage before we quote. No surprises after we’re in the crawlspace.
Post-Rain Moisture Assessment
After our wet winters, we check for standing water in low spots of flex duct. A camera finds what a flashlight at the register grille misses. If there’s water, we flag it. Cleaning damp duct without addressing the source just grows new mold.
Residential Air Duct Cleaning in Lakeland South
Residential Air Duct Cleaning in Lakeland South means source removal from supply and return ductwork, register grilles, and the air handler cabinet, using negative-air machines and rotary brush agitation. For a typical single-system home here, expect $350 – $550. Homes with two or three systems – common in Lakeland South’s larger rural properties – run $650 – $1,400 depending on total duct footage and contamination level. We price per system, not per vent, so a house with three HVAC setups gets three written prices, not a ballooning invoice at the door.
Multi-System Pricing for Larger Homes
Many Lakeland South properties have 2,500+ square feet with separate systems for main floor, addition, and guest quarters. Per-vent pricing punishes you for having more registers. Our per-system pricing means you know the full cost before we start, whether it’s one system or four.
Source Removal vs. Surface Vacuuming
We don’t just vacuum the grille. Our Nikro negative-air machines pull loosened debris out of the duct under controlled pressure while Rotobrush rotary tools scrub the interior walls. For Lakeland South’s older flex duct, we adjust brush tension so we clean without tearing fragile material.
Trusted Brands We Service in Lakeland South
Our equipment roster includes Nikro negative-air machines and Rotobrush rotary brush systems, plus filtration products from Honeywell and Aprilaire. We stock common replacement parts for these brands so Lakeland South customers aren’t waiting on shipping if we find a damaged component during cleaning. When a flex duct run off 112th Street needs replacement or an air handler cabinet needs a new Honeywell media filter, we can often complete the work same visit rather than scheduling a return trip.
Common Air Duct Cleaning Problems We See in Lakeland South Homes
- Crawlspace moisture wicking into duct runs. Lakeland South’s 40+ inches of annual rain keeps soil damp year-round. Flex duct laid directly on that soil pulls moisture through the vapor barrier over time, creating the musty smell homeowners often blame on their furnace.
- Original flex duct sagging and trapping water. The 1970s – 1990s flex duct common here loses tension after decades. Low spots form. After heavy rains, those low spots hold standing water. A tech who skips camera inspection cleans right over it.
- Rodent intrusion through chewed flex duct. Every fall, rats and mice seek shelter from the wet cold. Lakeland South’s crawlspace-mounted ductwork is accessible and chewable. We regularly find trunklines used as nesting highways, with contamination spreading through the entire system.
- Filter replacement without trunkline sealing. Homeowners change the filter but don’t realize the return trunkline has gaps or rodent damage. The new filter just recycles mold spores and rodent debris through clean pleats.

FAQs About Air Duct Cleaning in Lakeland South
Crawlspace ducts sit on damp soil and use flexible material that’s more fragile than rigid attic ductwork. We use lower-tension rotary brushes and always run camera inspection first to check for standing water or rodent damage before agitation. Attic systems are typically rigid metal or hard duct board – they can handle more aggressive cleaning and don’t have the moisture wicking problem.
Yes. We price each system separately with a flat rate agreed in writing before work starts. A typical three-system home in Lakeland South runs $950 – $1,400 total depending on duct footage and contamination. You’ll know the full cost before we touch anything. Call (361) 326-5060 for an exact quote – estimates are free.
Before-and-after photos of every duct run, the air handler cabinet, and any replaced components. We also provide a written summary of work performed, equipment used, and any recommendations for repairs or follow-up. For Lakeland South crawlspace systems, this documentation is essential – you’re trusting us with something you can’t verify yourself.
We see rodent damage in roughly half of the un-cleaned crawlspace systems we inspect in Lakeland South, especially in fall and winter. The damage shows as chewed flex duct with exposed insulation, droppings in the trunkline, and sometimes nesting material at low points. You may smell ammonia or see dark staining around supply registers before you know they’re there.
Yes. Our Nikro negative-air machines run HEPA filtration at 99.97% efficiency on every job, but in Lakeland South’s damp crawlspaces we also check that the collection drum seals properly against moisture-heavy debris. We never vent agitated air into the crawlspace – it all goes through HEPA filtration outside the home. The wet climate means we take extra care with containment so we don’t add moisture to an already damp system.
