Offices, hospitals, schools, government buildings and industrial plants across the USA. Moreover, commercial air duct cleaning with full HEPA containment, 24/7 mobilization and audit-ready documentation. Our commercial air duct cleaning follows EPA indoor air quality guidance and NADCA industry standards.
OSHA estimates about 30% of commercial buildings suffer below-standard indoor air quality.
Consequently, the NADCA ACR Standard calls for inspection-based cleaning — most buildings need 12–24 month cycles.
One certified crew standard, one scope, one report format — across every site in your portfolio.
Containment, negative pressure and HEPA filtration capturing 99.97% of 0.3-micron particles.
Dust, microbial growth and construction debris inside ductwork recirculate through occupied spaces all day — driving tenant complaints, sick building syndrome, higher energy bills and premature equipment failure.
Cleaning the complete air conveyance system — supply and return ducts, air handlers, coils, blowers, plenums and exhaust — restores design airflow, cuts HVAC energy waste, extends equipment life and reduces fire and liability risk. In addition, it is the engineering fix behind most successful sick-building remediations.
IAQ Restoration performs commercial duct cleaning for the most demanding clients in the country — Bank of America, IBM, Delta, Emory Healthcare, the US Army and Hartsfield-Jackson among them. For example, the numbers make the case:
Complete HVAC system inspection with video documentation before and after — you see exactly what we found and what we removed.
Supply, return and exhaust ducts cleaned to the NADCA ACR Standard, plus air handlers, coils, blowers and drain pans.
EPA-registered sanitizing treatments where conditions warrant, plus optional UV-C germicidal and air purification installation.
Scope, before/after photos, cleanliness observations and a recommended re-inspection cadence — audit-ready.
As a result, we clean air systems for hospitals and healthcare facilities, government buildings, military bases, schools and universities, corporate offices, senior living communities, courthouses and industrial buildings and warehouses nationwide.
In particular, commercial air duct cleaning is the inspection and source-removal cleaning of a building’s entire air conveyance system — the supply and return ductwork, air handling units, coils, blowers, plenums, diffusers and exhaust runs that move conditioned air through a facility. Unlike residential work, commercial duct cleaning services deal with rooftop units, VAV systems, long trunk runs, ceiling return plenums and equipment that runs nearly continuously — which is why NADCA certification, commercial-grade HEPA equipment and occupied-building experience matter.
Method matters just as much. IAQ Restoration uses source removal — the approach specified by the NADCA ACR Standard — combining mechanical agitation with continuous HEPA-filtered negative pressure, so contaminants leave the building instead of being redistributed through it. Fogging fragrance into vents or running a “blow-and-go” vacuum truck is not duct cleaning; insisting on documented source removal is how facility managers protect their buildings and their budgets.
Watch for dust puffing from diffusers at system start-up, dark smudge streaks on ceiling tiles around supply vents, musty odors that return no matter how often the space is cleaned, unexplained hot and cold zones, rising energy use without a rate change, and clusters of allergy or headache complaints in specific areas. Recent construction or renovation is an automatic trigger. Above all, the simplest test costs nothing: shine a flashlight through a return grille — if the visible surfaces show matted dust, the parts you can’t see look worse.
Importantly, the NADCA ACR Standard is inspection-based: assess system cleanliness annually, then clean when contamination exceeds benchmarks or moisture and microbial growth are present. High-traffic buildings and healthcare facilities typically clean every 12–24 months — and every building should be cleaned after construction projects or water events.
Nearly all of our commercial work happens in occupied buildings. Crews work nights, weekends and phased zones with daily hand-back, using physical containment and HEPA negative air so business hours are never touched — and the building is cleaner at 8 a.m. than we found it at 8 p.m.
On top of that, every building is different, so honest pricing starts with a site walk or a set of mechanical plans — not a per-vent coupon. In practice, the main cost drivers are the number and size of air handling systems, total ductwork footage and accessibility, ceiling heights and lift requirements, contamination level, and scheduling constraints such as night-only or phased work. As a rule, professional cleaning costs a fraction of what fouled coils quietly add to a building’s energy bill — and far less than the mechanical repairs that deferred contamination eventually causes. Quotes are free, itemized, and can be standardized across multi-site portfolios.
Ductwork is only half the system. Cooling and heating coils, blower assemblies and condensate pans are where airflow, moisture and dust meet — making them both the largest efficiency loss and the most common microbial reservoir in commercial HVAC. Meanwhile, our crews deep-clean coils to restore heat-transfer performance, treat drain pans with EPA-registered products, and decontaminate complete air handlers as part of every full-system scope. Beyond that, the EPA and Department of Energy both note that dirty coils and restricted airflow measurably increase HVAC energy consumption — which is why coil cleaning routinely pays for itself in reduced run-time.
Duct cleaning is where we start. In short, every major component of your commercial HVAC system has its own dedicated, NADCA ACR-verified cleaning service — explore the full HVAC component cleaning line-up.
Workstations wrapped, ceilings opened and closed section by section, HEPA-filtered negative air running the whole time. Most commercial cleanings run nights and weekends — your staff never knows we were there, except for the air.
Every project is photo-documented from first inspection to final walkthrough. You get the before-and-after evidence your compliance file, insurer or tenant board expects — not just an invoice.
System mapping and a containment plan built around your operations.
Physical barriers and HEPA negative-pressure isolation of each zone.
Agitation and extraction of deposits from every system component.
Matched-angle before/after photos and cleanliness checks.
Audit-ready closeout and preventive maintenance plan.
NADCA recommends inspecting commercial HVAC systems annually and cleaning based on verified conditions. High-traffic buildings and healthcare facilities typically clean every 12–24 months, and always after construction or water events.
Yes. Therefore, we work nights, weekends and phased zones with daily hand-back, using occupied-facility containment protocols so your operations never stop.
