AfterCommercial Duct Cleaning in Henderson, NV
Commercial duct cleaning in Henderson typically costs $0.28 to $0.45 per square foot, with most office and retail spaces between 5,000 and 20,000 square feet running $1,400 to $9,000 depending on system complexity, duct accessibility, and how long it’s been since the last cleaning. Hollis Air Duct Henderson handles commercial jobs with the same negative-air method and rotary brush equipment we run on residential duct cleaning systems, scaled up for larger duct networks. If you manage a building in Green Valley, Water Street District, or the commercial corridors along Stephanie Street and St. Rose Parkway, call (775) 383-5847 and we’ll give you a written line-item price before any equipment comes off the truck.
This page covers commercial work specifically. If you’re looking for residential service, our main Air Duct Cleaning in Henderson page covers homes step by step. For a broader look at how we run every job, start at our home page.
We’ve been cleaning ducts in the Las Vegas Valley since 2004, and commercial work is different from air duct cleaning for homes in ways that matter to building owners: tenants and employees notice stale air, kitchen exhaust carries grease that builds up fast, and the dust load from high desert wind is constant. The March through October season in Henderson means cooling systems run hard for months. That’s when the dust that got pulled into the system in the spring shows up as a haze in the morning light, a layer on cubicle partitions, and allergy complaints from staff. A proper commercial cleaning is an operational fix, not a cosmetic one.
When You Need Commercial Duct Cleaning
You don’t need to wait for a complaint to justify the work. Here are the signs we see most often in Henderson commercial buildings before someone picks up the phone:
- Visible dust accumulation on registers and ceiling tiles. If the diffusers are grey and the tiles around them are shadowed with dust, the duct interior is carrying more than it should. We see this constantly in buildings near the 215 and I-11 corridors where construction dust and high desert particulates work their way into rooftop intakes.
- Musty or stale odors when HVAC cycles on. Duct liners absorb humidity from cooling-season condensation, and once microbial growth starts in the liner it doesn’t dry out on its own. The smell is a biological signal from inside the system, not a filter problem.
- Occupant complaints about allergies, headaches, or stale air. Henderson buildings near Lake Las Vegas and the wetlands get a different particulate mix than those near the foothills. When multiple people report the same symptoms on the same floor or the same wing, the HVAC system is the common variable.
- Reduced airflow at vents. A layer of caked dust 1/8 inch thick on coil surfaces cuts heat transfer and airflow measurably. If some offices are freezing and others are warm, or if the system runs longer to hold setpoint, blocked coils and ducts are likely contributors.
- It’s been more than 3 to 5 years since the last cleaning. The National Air Duct Cleaners Association recommends commercial systems be inspected annually and cleaned every 3 to 5 years, sooner for kitchens, medical offices, or buildings near active construction.
- Post-construction or post-renovation dust. Drywall dust, paint overspray, and construction debris don’t stay in the work area. They get pulled into return ducts and redistributed through every room on the system. We clean several Henderson buildings every year right after a TI or remodel for exactly this reason.
Our Commercial Duct Cleaning Process
Here’s how we run a commercial job from first call to final walkthrough. Every step happens in writing where it counts.
- Walkthrough and system mapping. We walk the building with you or your facilities manager to map the system: rooftop units, VAV boxes, duct runs, returns, and access points. We note which areas are occupied, which have restricted access, and what hours we can run equipment without disrupting business.
- Written line-item price. Before any work starts, you get a written price that covers the scope we agreed on. It doesn’t move. If we find something during the job that changes the scope, we stop, show you what we found, and get your approval in writing before doing anything extra. That’s The Garrison Standard, and it’s how we’ve run every job since 2004.
- Negative-air containment. We connect a Nikro negative-air machine to the duct system, which puts the ducts under vacuum so dust and debris get pulled into the containment unit instead of blowing into offices. Every return and supply opening is sealed except the one we’re actively working on, which keeps the pressure differential doing its job.
- Agitation and extraction. We run a Rotobrush rotary brush system through the ducts. The brush scrubs caked-on debris off the duct walls while the negative-air pressure carries it downstream to the HEPA-filtered collection unit. For heavier commercial systems, we may use compressed-air agitation through access ports cut to industry standard and sealed with rated patches afterward.
- Coil and blower cleaning. The ductwork is only part of the system. We clean the evaporator coils, blower assembly, and drain pan as part of the job because a clean duct connected to a dirty coil is just a faster way to redistribute dirt. On rooftop units, this is where a lot of Henderson dust settles.
- Final walkthrough with photo documentation. Before and after photos of the main runs, coils, and access points so you have a record of what was done. The site is left clean. If anything isn’t right, you have our 365-Day Done Right Promise in writing: we come back and make it right at no charge, including a free second visit.
Commercial Duct Cleaning Pricing in Henderson
Here’s what commercial duct cleaning costs in Henderson based on the jobs we’ve priced in this market. These are honest ranges, not teaser quotes designed to get a technician in the door.
| Building Size | Typical Price Range | What’s Included |
|---|---|---|
| Under 5,000 sq ft (small office, retail suite) | $1,400 – $2,800 | Supply and return ducts, registers, coils on package units |
| 5,000 – 10,000 sq ft (medical office, restaurant dining area) | $2,800 – $4,500 | Full duct network, coils, blower, drain pans, photo documentation |
| 10,000 – 20,000 sq ft (multi-tenant office, church, school wing) | $4,500 – $7,000 | Full system with multiple rooftop units, access port work, coil pull-and-clean where accessible |
| 20,000+ sq ft (warehouse, large retail, industrial) | $7,000 – $12,000+ | Scoped per building; priced after walkthrough, written line-item quote |
| Kitchen exhaust hood duct (restaurant) | $600 – $1,800 | Grease duct cleaning priced separately from HVAC ducts due to fire-code requirements |
What moves the price in Henderson specifically: rooftop unit count and accessibility, whether the building has VAV boxes that need individual service, how much access port work is required, the length of duct runs, and the condition of the coils. A building near Sunset Station that shares an HVAC loop with a restaurant kitchen will price differently than a standalone professional suite near Anthem. We’ll tell you exactly why during the walkthrough, in plain terms, and every number goes in writing before we begin.
Call (775) 383-5847 for a free estimate. A facilities manager we work with in Green Valley put it simply: the written price is the reason they keep calling us. No one on their team has to defend a surprise line item to ownership.
FAQs – Commercial Duct Cleaning
How much does commercial duct cleaning cost in Henderson, NV?
Commercial duct cleaning in Henderson runs $0.28 to $0.45 per square foot, so a 10,000 square foot office typically costs $2,800 to $4,500 depending on system complexity, rooftop unit count, and duct condition. Kitchen exhaust ducts are priced separately due to fire-code cleaning requirements. Call (775) 383-5847 and we’ll give you a written line-item price after a walkthrough, free of charge.
Is it cheaper to clean commercial ducts or replace them?
Cleaning is almost always cheaper than replacement. A full commercial duct replacement in Henderson runs $10 to $25 per square foot, while cleaning that same system runs $0.28 to $0.45 per square foot. Replacement only makes sense when ducts are physically damaged, collapsed, or lined with material that can’t be restored. We’ll tell you straight if your system is better served by replacement than a full system cleaning, and we don’t sell replacement work, so the advice isn’t weighted toward our invoice.
How long does commercial duct cleaning take?
Most Henderson commercial jobs take 1 to 3 days depending on building size and system layout. A small retail suite under 5,000 square feet can often be done in a single day, while a 20,000 square foot building with multiple rooftop units usually runs 2 to 3 days. We schedule around your operating hours where possible, so the work doesn’t shut you down.
Can commercial duct cleaning reduce energy bills?
Yes. A layer of dust on coils and blower wheels reduces heat transfer and airflow, which makes the system run longer and work harder to hit setpoint. After cleaning, we routinely see static pressure drop and airflow improve, especially on Henderson rooftops where return duct cleaning matters most because high-desert dust loads are constant through the cooling season. The energy savings depend on how dirty the system was, but the mechanical relationship between a clean coil and lower runtime is direct.
Do you clean kitchen exhaust ducts?
Yes, we clean kitchen exhaust hood ducts for Henderson restaurants and commercial kitchens, priced separately from HVAC ducts because grease removal and fire-code compliance are different scopes of work. Grease-laden exhaust is a fire hazard, and the cleaning frequency depends on cooking volume and fuel type. Call (775) 383-5847 and we’ll walk the hood system with you and put a written price on it.
What is the 365-Day Done Right Promise?
It’s our written guarantee on every commercial job: if anything we cleaned doesn’t stay clean or the work fails within a year, we return and make it right at no charge, including a free second visit. It’s in writing on every invoice, not buried in fine print. Since 2004, that promise has been the standard we hold ourselves to on every Henderson job, residential or commercial.
