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.
Fast, Reliable Air Duct Cleaning Across Essex
Air duct cleaning in Essex, MA typically runs $350 – $650 for a full residential system and is scheduled within a few days of your call. Most Essex homes need it done every 3 – 5 years, sooner if you smell must from the vents or your energy bills have climbed without explanation.
We’ve been sending crews to Essex since 2004, and the phone gets answered by a live person no matter when you call. Roy Castellanos built Hollis Air Duct Cleaning on The Garrison Standard: written price before any work starts, background-checked uniformed technicians, and a 365-Day Done Right Promise that puts our guarantee in writing on every job. In Essex, that matters more than in most places. This town sits on tidal marshland between the Back River and Middle River, and the humidity here finds every gap in old ductwork. We’ve pulled standing water out of basement duct boots in Sandalwood and traced mildew through returns in Hyde Park that had nothing to do with household dust and everything to do with crawl-space vapor pushing upward. If your home was built in the 1950s or 1960s with original galvanized duct or early flex runs, you already know the smell we’re talking about. Call (361) 326-5060 for a free estimate and we’ll show you exactly what’s inside your system before we quote a price.
Why Hollis Air Duct Cleaning Is Essex’s Preferred Air Duct Cleaning Company
Essex homeowners don’t hire us because we’re the cheapest. They hire us because the price we write down is the price they pay, and because our technicians arrive in uniform, on time, and inside the quoted window. That’s The Garrison Code in action, and it’s how we’ve operated since 2004.
Roy Castellanos runs this location as part of the Garrison Partners family, but each Hollis office is independently owned and operated. What that means for Essex is local accountability. If something fails within a year, we come back and make it right at no charge, including a free second visit. No negotiating, no runaround.
Our dispatch and scheduling are coordinated from our Boston office, but the crews serving Essex live and work in the area. They know the difference between a post-WWII rowhouse on Eastern Boulevard and a 1960s ranch off Eastern Avenue, and they know which ones are still running oil-to-gas converted furnaces with ductwork that hasn’t been touched in decades.
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 morning to get on the schedule.
Ductwork Cleaning in Essex
Ductwork Cleaning in Essex means dealing with systems that have spent sixty or seventy years fighting tidal humidity, crawl-space flooding, and the slow deterioration of galvanized steel in salt air. We don’t just vacuum dust. We use Rotobrush rotary brush systems and Nikro negative-air machines to dislodge and extract the buildup that Essex’s climate deposits in your ducts: mildew, pollen, pet dander, and the fine silt that comes up from damp crawl spaces during wet seasons.
Most Essex homeowners call us when they notice musty odors when the heat kicks on, uneven temperatures between rooms, or a spike in energy bills that tracks with the humidity. If your house has a partial basement or slab-on-grade duct runs near the Back River, you may need cleaning more often than the standard 3 – 5 year interval.
Full System Cleaning
We clean supply ducts, return ducts, and the main trunk lines in one visit. In Essex’s older ranches, we often find the return plenum packed with debris from decades of neglect. Our negative-air method pulls contaminants out under controlled suction so nothing escapes into your living space.
Supply and Return Separation
Returns in Essex homes work harder than supplies because they draw humid crawl-space air across the filter. We clean each side separately to avoid cross-contamination and to spot moisture damage that might need Duct Sealing in Essex before the next humid summer hits.
Air Duct Inspection in Essex
Air Duct Inspection in Essex should happen before you buy any cleaning package, and it’s free when you call Hollis. We run a video camera through your trunk lines and show you the footage on a handheld monitor. In Essex’s riverside neighborhoods, we regularly find standing water in the basement boots, collapsed flex duct in crawl spaces, and galvanized runs so corroded that cleaning alone won’t solve the problem.
The inspection tells us whether you need a straightforward cleaning, duct sealing to stop moisture intrusion, or replacement of damaged sections. We don’t sell you work you don’t need. The Garrison Standard requires us to price in writing before we touch anything, and that starts with an honest look inside.
Video Documentation
We record the inspection and can leave you with still images of problem areas. When we find mold in a return tied to a wet crawl space in Hyde Park or Sandalwood, you’ll see exactly where it’s coming from and why Dryer Vent Cleaning in Essex or duct sealing might be the smarter first step.
Post-Cleaning Verification
After our Air Duct Cleaning team finishes, we re-inspect to confirm the debris is gone and the system is intact. In Essex’s older housing stock, we’ve found loose connections that were hiding behind decades of buildup. We flag them before they become air leaks or moisture entry points.
Trusted Brands We Service in Essex
Our equipment comes from Nikro, Honeywell, and Aprilaire, the same names commercial crews trust for hospitals and schools. We stock filters and replacement parts sized for Essex’s common furnace configurations, including the older oil-to-gas converted systems still running in rowhouses along Eastern Boulevard. That means faster turnaround and no waiting for special orders when your system needs attention. If your home has a Honeywell electronic air cleaner or an Aprilaire media filter, we know how to integrate our cleaning process with those components without damaging the sensitive electronics or voiding any remaining warranty.
Common Air Duct Cleaning Problems We See in Essex Homes
- Humidity-driven mildew in returns. Essex’s location on the Back and Middle Rivers means year-round moisture that inland Baltimore County towns don’t face. We regularly find return ducts coated in mildew that traces back to crawl-space vapor, not household dust.
- Standing water in basement duct boots. After coastal flood events or even heavy spring rains, low-lying blocks around Sandalwood and Hyde Park see water intrusion into slab-on-grade duct runs. Cleaning alone won’t fix this; we flag it for sealing or drainage work.
- Collapsed or disconnected flex duct in crawl spaces. Essex’s 1950s-60s ranches often have early flex duct that has deteriorated from decades of humidity cycling. We find sections hanging loose, blowing conditioned air into the crawl space instead of the bedroom above.
- Galvanized steel corrosion in original rowhouse systems. The post-WWII brick and formstone homes along Eastern Avenue still run original galvanized duct that flakes rust into the airstream. Our rotary brush system removes the loose material without punching through the thin remaining metal.
Pricing for Air Duct Cleaning in Essex, MA
A typical residential duct cleaning in Essex runs $350 – $650 for a full system, depending on the number of vents, the accessibility of your trunk lines, and whether we find moisture damage that needs addressing first. Commercial systems in Essex’s small retail and restaurant spaces along Eastern Boulevard start around $800 and scale with square footage and HVAC complexity.
We price by the complete system, not by the vent. That means no surprise add-ons when the technician counts fourteen returns instead of ten. The price is written down before any work starts, and it does not move at the door. Factors that can push Essex jobs toward the higher end include crawl-space access requiring extra setup time, heavy mildew remediation, or the need to clean both the ductwork and the blower assembly on an older oil-to-gas converted furnace.
Every estimate is free. Call (361) 326-5060 and we’ll schedule a time that works for you.

Yes. We serve Sandalwood, Hyde Park, and the full corridor along Eastern Boulevard and Eastern Avenue. The riverside homes near the Back River and Middle River are actually where we do some of our most important work, since the humidity and flood risk there create duct problems that inland crews often misdiagnose.
We answer the phone live 24 hours a day, 7 days a week, and we can often accommodate urgent requests for Essex homeowners dealing with post-flood contamination or sudden system blockages. True emergencies, like a completely blocked return causing furnace shutdown, get priority scheduling. Call (361) 326-5060 anytime.
Essex pricing sits in the same range as Beverly and Gloucester for standard residential systems, typically $350 – $650. Essex’s older housing stock and higher humidity can push some jobs toward the upper end if we find moisture damage or corroded galvanized duct that needs extra attention. We don’t charge differently by zip code; the written price reflects the actual condition of your system.
If any part of our cleaning fails within one year, Hollis returns and makes it right at no charge, including a free second visit. That covers re-contamination due to incomplete cleaning, damage to ductwork from our equipment, and any workmanship issue tied to the original service. The promise is backed in writing on every Essex job, not just verbal assurance. If you suspect a problem, call (361) 326-5060 and we’ll schedule the follow-up promptly.
