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 Fort Collins
Air duct cleaning in Fort Collins typically runs $350 – $650 for a whole-home system and is usually scheduled within a few business days, with dispatch coordinated from our Denver office. Our crews serve Fort Collins neighborhoods directly, from the older ranches around Old Town to the newer subdivisions south of Harmony Road.
We’ve been inside enough homes in Fort Collins to know the pattern: a 1968 ranch on Swallow Road with original sheet-metal trunk lines, or a split-level near Miller with branch ducts buried in an unvented crawlspace drawing in soil gases. The high-altitude dryness here, that 15 – 25% relative humidity you feel every winter, turns household dust into something that floats easily and static-clings to duct interiors. Then the October-to-April heating season pushes that same dust through your living space for six months straight. Roy Castellanos and our team at Hollis Air Duct Cleaning treat Fort Collins as a distinct market, not a Denver afterthought, because the housing stock and climate here create problems that don’t show up the same way in Greeley or Boulder.

Why Hollis Air Duct Cleaning Is Fort Collins’s Preferred Air Duct Cleaning Company
Our reputation in Fort Collins was built job by job, starting back in 2004 when we first began serving northern Colorado as part of the Garrison Partners family. Homeowners here talk, especially in tight-knit neighborhoods like Andersonville where a good or bad contractor experience travels fast at the farmers market or the neighborhood association meeting.
We answer our phones with a live person, 24 hours a day, seven days a week. No voicemail loops, no “leave a message and we’ll call back Monday.” For Fort Collins scheduling, that means you can reach us on a Sunday evening to book your Wednesday appointment without waiting for business hours.
Our technicians arrive inside the quoted window, in uniform, background-checked, with the job specs already reviewed. The Garrison Code requires it: show up squared away, price it in writing before touching anything, leave the site clean. In a market where too many homeowners have watched a low quote balloon once the van is in the driveway, that discipline matters.
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 a document you sign.
Commercial Air Duct Cleaning in Fort Collins
Commercial Air Duct Cleaning in Fort Collins covers office buildings, retail spaces, restaurants, and multi-unit properties where code compliance and occupant health intersect with the reality of high-altitude dust loads and extended heating seasons. We use Nikro negative-air machines to create controlled suction throughout the system, preventing debris from escaping into occupied spaces during cleaning. For Fort Collins businesses, typical commercial duct cleaning runs $800 – $2,500 depending on system size and accessibility.
Restaurant and Food-Service Systems
Grease-laden vapors from cooking equipment migrate into supply and return ducts over time, creating fire hazards and odor problems. We clean these systems to NFPA 96 standards using rotary brush agitation and HEPA-contained extraction, then document the work for your next health department inspection.
Office and Retail Maintenance
Fort Collins office buildings with VAV boxes and flex-duct drops need periodic cleaning to maintain airflow balance and prevent the “stale air” complaints that spike in January when the heating system runs continuously. Our crews work after hours or in zones to minimize business disruption.
Air Duct Cleaning Services in Fort Collins
Air Duct Cleaning Services in Fort Collins address the specific problems created by this city’s semi-arid climate and aging suburban housing stock. We clean supply ducts, return ducts, trunk lines, and registers using Rotobrush rotary brush systems for mechanical agitation paired with negative-air containment from Nikro equipment. A typical residential full-system cleaning in Fort Collins costs $350 – $650, with video inspection available to show you the before-and-after condition of your ducts.
Supply and Return Duct Cleaning
Supply ducts push conditioned air into your rooms; return ducts pull it back. In Fort Collins homes built in the 1960s and 70s, these runs are often poorly sealed fiberglass flex or sheet metal with failing tape joints. We clean both sides of the loop because dirty returns recontaminate clean supplies immediately.

Video Inspection and Documentation
Before we start, we feed a camera through your trunk line so you see what we see: the dust buildup, the debris, the gaps in sealing. After cleaning, we run it again. The difference is your proof that the work happened, not just a verbal assurance.

Trusted Brands We Service in Fort Collins
We maintain and install filtration and air-quality equipment from Honeywell, Aprilaire, and Abatement Technologies, the same brands specified in commercial buildings throughout Fort Collins and northern Colorado. Our trucks carry common Honeywell media filters and Aprilaire humidifier pads because the dry winters here, that relentless 15 – 25% relative humidity, destroy standard filters faster than in moister climates. When your system needs a replacement part, we don’t order it and make you wait; we stock it. That matters in Fort Collins, where a failed filter during a January cold snap means your heating system runs dirty for days until a part arrives from Denver.
Common Air Duct Cleaning Problems We See in Fort Collins Homes
- Original slab-embedded ductwork in Old Town and midtown ranches. The expansive clay soils and 1960s slab-on-grade construction in older Fort Collins neighborhoods mean supply ducts are sometimes cast into the concrete foundation or run through unvented crawlspaces that draw in radon and soil gases. Cleaning here requires source-control thinking, not just vacuuming.
- Static-cling dust buildup from ultra-low humidity. Fort Collins’s semi-arid climate keeps relative humidity low enough that dust particles develop static charge and adhere to metal duct walls rather than flowing through to the filter. Our rotary brush systems physically break that bond.
- Seasonal microbial spikes during summer monsoons. Those brief July humidity spikes to 50% or higher, rare as they are, can activate dormant dust mite populations and microbial growth in cooling coils and duct interiors that sat dry for ten months. We inspect for this during annual cleanings.
- Leaky branch runs in unconditioned attics and crawlspaces. The 1950s – 1970s ranches and split-levels in neighborhoods like Miller and Andersonville often have short branch ducts in spaces that hit 120°F in summer and below freezing in winter. The thermal stress cracks seams, and the pressure imbalance pulls in insulation fibers and rodent debris.
Pricing for Air Duct Cleaning in Fort Collins, CO
Whole-home air duct cleaning in Fort Collins runs $350 – $650 for a typical single-family system with 8 – 15 registers. Smaller condos or townhomes start around $250; larger homes with 20+ registers, multiple HVAC units, or slab-embedded ductwork requiring specialized access can reach $800 – $1,200. Dryer vent cleaning added to a duct cleaning appointment runs $120 – $180. We also handle Dryer Vent Cleaning in Fort Collins as a standalone service.
What moves the price: number of supply and return registers, whether the system includes a main trunk line and multiple branch levels, accessibility (crawlspace work costs more than basement access), and whether video inspection or Duct Sealing in Fort Collins is included. We also handle duct sealing as a standalone or add-on service for homes with significant leakage.
Every price is written down before we touch your system. No per-vent add-ons, no “we found mold” upsells at the door. The number you approve is the number you pay. Call (361) 326-5060 for a free estimate.

FAQs About Air Duct Cleaning in Fort Collins
We typically schedule Fort Collins appointments within 2 – 4 business days, with dispatch coordinated from our Denver office. Call (361) 326-5060 to check current availability; we don’t overbook, so the window we give you is the window we keep.
We cover all Fort Collins neighborhoods including Old Town, Andersonville, Miller, the subdivisions south of Harmony Road, and everything in between. Our crews know the local housing stock, from 1960s ranches with slab-embedded ductwork to newer builds with flex-duct systems.
We don’t treat duct cleaning as an emergency service; it’s a scheduled maintenance job that requires proper setup and equipment. If you’re experiencing an urgent HVAC failure, we recommend contacting an HVAC repair specialist first, then scheduling duct cleaning once the mechanical issue is resolved.
Fort Collins pricing is comparable to Denver, sometimes slightly lower due to shorter travel distances from our dispatch point. The main cost drivers are system size and accessibility, not city location. A typical whole-home cleaning in Fort Collins runs $350 – $650, same range you’d see in the metro area.
Every Fort Collins job is covered by our 365-Day Done Right Promise in writing. If the cleaning fails to resolve the documented problem within one year, or if workmanship issues appear, we return and make it right at no charge, including a free second visit. The guarantee is tied to the work, not the location, so it travels with you if you sell the home and the new owner experiences the same issue.
