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’re the Coalinga crew from Hollis Air Duct Cleaning, dispatched out of our Fresno office to serve the west San Joaquin Valley directly. If your registers are blowing fine dark grit, your back bedrooms won’t cool below 80°F even with the AC cranked, or your energy bills have climbed without explanation, the problem is usually in the ductwork, not the unit itself. Call us at (361) 326-5060 for a free estimate, and we’ll show you exactly what we find before any work starts.
Why Hollis Air Duct Cleaning Is Coalinga’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our Coalinga customers know we operate on The Garrison Standard: arrive inside the quoted window, price it in writing before touching anything, finish by the book, and leave the site clean. Our technicians are background-checked and uniformed, and our phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops. No callback queues.
Every job carries our 365-Day Done Right Promise in writing. If the work fails within a year, we come back and make it right at no charge, including a free second visit. That’s not a slogan. It’s printed on every invoice.
We know Coalinga’s housing stock: the post-WWII ranches along Sunset Drive, the rebuilt and retrofitted homes in neighborhoods patched after the 1983 earthquake, and the newer tract developments near the city edge. That local knowledge matters because Coalinga ducts fail in specific ways that generic crews miss.
Air Duct Cleaning Services in Coalinga
Air Duct Cleaning Services in Coalinga mean pulling accumulated debris from your entire forced-air system, not just wiping the registers and calling it done. We use Rotobrush rotary brush systems and Nikro negative-air machines to agitate and extract buildup from supply trunks, return trunks, branch lines, and the plenum. In Coalinga, that buildup is rarely ordinary household dust. It’s a fine, dark grit, oil-field particulate mixed with Valley agricultural dust, that settles deep in return trunks and coats the blower motor. A typical residential full-system cleaning in Coalinga runs $350 – $650, depending on system size, accessibility, and whether we find disconnected or crushed runs that need repair.
Residential Duct Cleaning
Our residential crews clean the full system: supply ducts, return ducts, registers, grilles, and the air handler cabinet. We run a video camera first so you see what we’re seeing. In Coalinga’s older homes, we often find original 1950s metal trunk lines sitting inches from earthquake-era retrofits that were never properly sealed together.
Commercial Duct Cleaning
Commercial systems in Coalinga’s industrial and retail buildings see heavier loading from outdoor air intakes and longer runtimes. We scale our negative-air setup and rotary brush agitation to match duct gauge and building occupancy, with scheduling that doesn’t shut down your operation.

HVAC Duct Cleaning in Coalinga
HVAC Duct Cleaning in Coalinga addresses the entire heating, ventilation, and air conditioning pathway, from the return air grille through the filter, blower, heat exchanger or coil, and out to every supply register. In Coalinga’s semi-arid climate, where summer temperatures regularly exceed 100°F and windy conditions blow dust and agricultural particulates straight into outdoor HVAC units, the load on your ducts is constant and heavy. A full HVAC duct cleaning here typically costs $400 – $700 for residential systems, with commercial quotes provided after site inspection. We don’t guess. We inspect with a camera, write the price down, and stick to it.
Video Inspection Before Work
We feed a borescope camera through your ductwork and show you the footage. In Coalinga, that footage usually reveals seismic-era gaps at the air handler, crushed runs behind remodeled closets, and that characteristic dark grit coating the return trunk. You see it. We see it. Then we agree on what needs doing.
Duct Sealing and Repair
Cleaning without sealing is temporary in Coalinga. We use duct sealing mastic and mechanical fasteners to close gaps we find, reconnect detached flex joints, and replace crushed or deteriorated sections. The price for sealing work is added to your written estimate before we start, never after.
Trusted Brands We Service in Coalinga
Our equipment comes from Rotobrush, Nikro, and Abatement Technologies, and we install filtration and air-cleaning products from Honeywell, Aprilaire, and Guardsman. These are the same brands commercial crews use in hospitals and industrial facilities, not hardware-store attachments. For Coalinga customers, that means parts and filters are available without long waits, and our technicians are trained on the specific torque settings, sealants, and clearances each manufacturer requires. If your system needs a media filter upgrade or a UV air purifier added during the cleaning, we stock the common sizes and configurations for Valley HVAC setups.
Common Air Duct Cleaning Problems We See in Coalinga Homes
- Seismic-era gaps and unsealed joints. Ducts patched or rerouted after the 1983 earthquake often have unsealed connections at the air handler and inside wall cavities. Cleaning alone without sealing means the same oil-field grit re-enters your system within weeks.
- Crushed or disconnected runs hidden by remodeling. We regularly find branch lines pinched flat behind added closets or room additions, especially in the older ranches near the old oil-field edge. That’s why a back bedroom never cools, no matter how hard the AC runs.
- Dark fine grit coating blower motors and return trunks. This isn’t ordinary dust. It’s oil-field and agricultural particulate unique to Coalinga’s environment, and it settles deep where register-only cleaning can’t reach.
- Original and retrofitted ductwork sitting unconnected. In Coalinga’s split housing stock, we often open a wall cavity and find a 40-year-old original trunk a few feet from a newer, poorly connected run that was never sealed to it. Two systems, neither doing the full job.

FAQs About Air Duct Cleaning in Coalinga
Coalinga’s combination of oil-field particulate, agricultural dust, and frequent windy conditions creates a heavier, finer grit that loads ducts faster than ordinary household dust in other Valley towns. The 1983 earthquake also left many homes with patched or retrofitted ductwork that has unsealed gaps, pulling in attic and crawl-space debris continuously. Most Coalinga homeowners we serve schedule cleaning every 3 – 5 years rather than the typical 5 – 7. Call (361) 326-5060 and we’ll inspect your system to give you a specific recommendation.
Yes, earthquake-era repairs in Coalinga frequently involved rerouting or patching ductwork without fully sealing new connections to original trunk lines. We regularly find retrofitted runs sitting unsealed a few feet from 40-year-old originals, creating leaks that pull in attic air and drop system efficiency by 20% or more. A video inspection reveals exactly what you’ve got. We provide that inspection free with every estimate.
The dark grit is a mixture of oil-field particulate, agricultural dust, and standard organic debris, compressed by your blower into a fine, oily layer that coats return trunks and motor housings. It’s not typically toxic, but it reduces airflow, forces your HVAC system to run longer, and can aggravate allergies or asthma in sensitive individuals. More importantly, it’s a symptom of gaps or leaks that are letting unfiltered outside air into your system. We remove it under negative pressure with rotary brush agitation, then seal the leaks so it doesn’t return.
We do both, and we quote the repair work in writing before we start. Cleaning without sealing is temporary in Coalinga. Our techs are trained to reconnect detached flex joints, replace crushed runs, and seal gaps with mastic and mechanical fasteners. The full fix costs more than vacuuming alone, but it’s the only way to solve the actual problem. You’ll know the full price before we touch anything.
We show you before-and-after video from our borescope inspection, measure static pressure at your registers before and after, and leave you with a written completion checklist signed by the technician. Our 365-Day Done Right Promise covers the work for a full year: if the same problem returns or the cleaning fails, we come back at no charge, including a free second visit. That’s The Garrison Standard, and it’s on every job we do in Coalinga.
