Contaminated air ducts circulate dust, allergens, mold spores, and bacteria through every room in your home. Houston Air Duct Nova's NADCA-certified technicians clean, sanitize, and restore your ductwork — improving indoor air quality and system efficiency. Available 24 hours a day, every day.
Seventeen years of professional air duct service in Houston's demanding climate has taught us what works, what lasts, and what truly makes a difference in the air your family breathes every day.
Every technician at Houston Air Duct Nova holds National Air Duct Cleaners Association (NADCA) certification — the gold standard in the duct cleaning industry. This means every job is performed to a verified technical standard, not just a general guideline. Our certifications are current, our training continuous, and our results consistently exceed industry benchmarks for cleanliness and air quality improvement.
Houston's high humidity and long cooling season create uniquely demanding conditions for HVAC duct systems. Moisture infiltration, mold proliferation, and the continuous cycling of a Houston air conditioner create ductwork challenges that national franchises with generic protocols handle poorly. We've cleaned over 11,000 Houston homes and understand every neighborhood's specific conditions — from the Third Ward to Memorial to Sugar Land.
Mold in your ducts doesn't wait for business hours. Neither do we. Houston Air Duct Nova's emergency dispatch team operates around the clock, every day of the year including all holidays. If you discover visible mold growth in your vents, experience sudden allergy spikes correlated with your HVAC system, or need duct cleaning after a water intrusion event, we can have a certified technician at your Houston property within hours of your call.
We never use portable consumer-grade equipment for professional duct cleaning. Houston Air Duct Nova deploys truck-mounted vacuum systems generating negative pressure that far exceeds what portable units can achieve. Combined with rotating brush and compressed air whip systems, we achieve the deep mechanical agitation and powerful extraction that genuinely removes settled contamination — not just surface debris that would be redistributed with lesser equipment.
We provide photographic documentation of your duct condition before we start and after we finish — so you can see exactly what was removed from your home's air system. This transparency reflects our confidence in the quality of every cleaning we perform and gives Houston homeowners real evidence of the improvement in their indoor air quality rather than simply taking a contractor's word for it.
We quote the full job price upfront, in writing, before any work begins. No add-on fees discovered mid-job, no bait-and-switch tactics common in the duct cleaning industry, no charges for equipment we didn't use. The price we quote is the price you pay. We also offer flexible financing options and multi-service bundle discounts for Houston homeowners who want to combine duct cleaning with dryer vent or coil service.
From residential duct cleaning to full commercial HVAC system decontamination — Houston Air Duct Nova provides the comprehensive indoor air quality services Houston properties require.
Our 4.9-star rating comes from thousands of Houston families who've experienced the difference that genuinely clean ductwork makes in their homes.
After my daughter's asthma worsened over the summer, our pediatrician recommended having our ducts inspected. Houston Air Duct Nova came out the next morning, found significant mold growth in three duct runs, and performed a complete sanitization the same day. Within two weeks her symptoms had noticeably reduced. I cannot recommend them highly enough.
Our dryer was taking three cycles to dry one load — I thought the machine was dying. Houston Air Duct Nova cleared a completely compacted lint blockage from the vent line. The technician was professional, fast, and honest. Dryer works perfectly now and we avoided a potential fire hazard we didn't even know existed.
We used Houston Air Duct Nova for our office building on Westheimer after employees complained about dust and musty odors from the vents. The commercial cleaning team was efficient and minimized disruption to our business completely. The before and after photos were shocking — the improvement in air quality has been immediately noticeable to every employee.

Houston's climate is one of the most demanding in the United States for HVAC and duct systems. With humidity levels regularly exceeding 80% during summer months, air conditioning systems run almost continuously from April through October — pulling enormous quantities of airborne particulates, pollen, dust mites, and biological contaminants into duct systems that then distribute them throughout every room. The EPA estimates indoor air can be two to five times more polluted than outdoor air, and in Houston's climate, that figure can be significantly higher in homes with duct systems that haven't been professionally cleaned in three or more years.
Our NADCA-certified team uses professional truck-mounted vacuum systems, high-pressure compressed air agitation equipment, and EPA-approved antimicrobial sanitizers to perform thorough, verifiable duct cleaning that meets or exceeds the NADCA ACR Standard — the most rigorous published cleaning standard in the air duct industry. Every project is documented photographically and includes a written service summary you can keep for your HVAC maintenance records.
To schedule service or request a free estimate, call us at +1 224-780-4340 or email info@houstonairductnova.site. We are available around the clock, 365 days a year, and provide same-day service for most Houston locations.
Seventeen years of dedicated air duct service in Houston — built on technical precision, community trust, and an unwavering commitment to the air quality inside every home we serve.
Houston Air Duct Nova was founded in 2007 with a clear purpose: to bring genuinely professional, verifiably effective air duct cleaning to a Houston market full of companies offering cut-rate service that rarely delivered meaningful results. Our founders had worked in the HVAC industry for years and watched homeowners repeatedly pay for "duct cleanings" that amounted to little more than a shop vac run through accessible vents — leaving the true contamination in place and the homeowner no better off than before.
From our first day of operation, we committed to doing it differently. We invested in professional truck-mounted vacuum equipment capable of generating the negative pressure that NADCA standards require. We hired technicians willing to pursue NADCA certification and complete ongoing technical education. We built our pricing model around complete transparency — quoting the full job before starting and never adding charges mid-service. And we built our reputation entirely on the results we delivered in real Houston homes.
Over seventeen years, Houston Air Duct Nova has grown from a two-truck operation serving the inner loop to one of the largest and most recognized air duct cleaning companies in the Houston metropolitan area. We've cleaned over 11,000 residential properties, hundreds of commercial buildings, and dozens of new construction projects across Harris, Fort Bend, Montgomery, and Galveston counties.
Houston's humidity, heat, and year-round pollen load make duct cleaning not a luxury but a genuine health necessity — and we approach every project with that understanding. When a family calls us because a child's asthma has worsened, or a homeowner notices mold smell when the AC runs, we understand the urgency. Our technicians arrive prepared, work thoroughly, document everything, and leave every Houston home with measurably cleaner air.
We are proud members of NADCA, the Better Business Bureau, and the Houston Chamber of Commerce. Our team of over 30 certified technicians and support professionals lives and works in the same Houston neighborhoods we serve, and our reputation is built entirely on the quality of the work we do — one duct at a time, one home at a time, one family at a time.
Locally owned and operated from day one. Headquartered in the Third Ward at 1622 Live Oak St.

These are the non-negotiable standards that guide every technician, every project, and every customer interaction at Houston Air Duct Nova.
Indoor air quality is a health issue, not just a comfort issue. We approach every project with the understanding that the air circulating through a home's duct system directly affects the respiratory health of everyone inside — and that responsibility gives our work a purpose beyond customer satisfaction.
We follow NADCA cleaning standards on every job — not when convenient, not when the customer is watching closely, but always. Our certifications mean something to us, and we protect them by maintaining the technical discipline they represent every time we put our equipment to work in a Houston home.
Customers have the right to know exactly what they're paying for and exactly what was done. We document before and after conditions, provide written service summaries, and never change our price once we've given a quote. Transparency builds trust, and trust builds a business that lasts.
We are a Houston company in every meaningful sense. We hire locally, contribute to local charitable organizations, and are deeply invested in the health of the communities we serve. Our business exists to improve indoor air quality across Houston — and that mission gives our entire team genuine motivation.

Every service we provide is performed to NADCA ACR standards, documented photographically, and backed by our satisfaction guarantee.
Air duct cleaning removes the accumulated contamination — dust, pet dander, pollen, insect remains, construction debris, and biological material — from every component of your home's forced-air duct system. The EPA and NADCA both recognize professional duct cleaning as a meaningful contributor to improved indoor air quality, particularly in homes with occupants experiencing respiratory conditions, allergies, or asthma.
Our process begins with a thorough video inspection of your entire duct system, documenting existing conditions in all accessible duct runs, supply registers, return grilles, and main trunk lines. We then establish negative pressure throughout the system using our truck-mounted vacuum equipment — rated to move far more cubic feet per minute than portable units — before performing mechanical agitation using rotating brush systems and compressed air whipping devices that dislodge compacted contamination suction alone cannot remove.
Following mechanical cleaning of all duct runs, we apply an EPA-registered antimicrobial sanitizer to the interior duct surfaces to eliminate any remaining biological contamination — mold spores, bacteria, and dust mite populations. We clean all supply registers, return grilles, blower compartment components, and air handler components accessible without refrigerant system entry. Final photographic documentation and a written service summary are provided before we leave.
Dryer vent fires are responsible for approximately 15,000 home structure fires in the United States every year, according to the U.S. Fire Administration — making dryer vent cleaning one of the most important fire prevention services a homeowner can schedule. Lint accumulation in dryer vent lines restricts airflow, forces your dryer to work harder and run hotter, and creates a highly combustible blockage that combined with ignition temperatures from the heating element produces a serious and preventable fire risk.
In Houston's humid climate, dryer vent lines face an additional challenge: moisture from dryer exhaust can condense in long vent runs or incorrectly pitched lines, creating damp lint deposits that are not only a fire hazard but a potential mold source inside the vent line itself. Houston Air Duct Nova's dryer vent cleaning team is experienced with the complex vent routing common in Houston townhomes, two-story homes, and multi-unit buildings where vent lines may run through multiple floors or walls.
Our service includes full inspection of the vent line from dryer connection to exterior termination cap, mechanical cleaning using flexible rotary brush systems, airflow measurement before and after cleaning to document restored performance, and inspection of the exterior cap for proper operation and pest exclusion. We identify and report any damaged vent sections or improper materials that may require correction for safe dryer operation.
Houston's humidity creates one of the most mold-conducive environments in the United States. When moisture infiltrates ductwork — through condensation on cold supply ducts, humid air drawn in from attic spaces, or water intrusion during Houston's intense rainstorms — mold colonies can establish in duct systems within 48 to 72 hours and begin dispersing spores throughout the home with every HVAC cycle. Occupants may experience nasal irritation, coughing, eye irritation, or worsening respiratory conditions before any visible signs of contamination appear.
Our mold remediation service begins with a comprehensive video camera inspection to assess mold growth in all duct sections, followed by air sampling when contamination levels are in question. Our remediation protocol combines negative air pressure containment, physical removal of contaminated material where necessary, EPA-registered antimicrobial treatment of all affected surfaces, and HEPA filtration of the work area. We document the remediation process throughout and provide post-remediation verification of cleaning effectiveness.
We also address the moisture sources that enabled mold growth — poorly insulated ducts, disconnected joints allowing humid attic air infiltration, and condensate drainage issues — to prevent re-contamination after remediation. A duct system remediated without moisture source correction will re-contaminate, and we ensure our Houston customers receive lasting results, not temporary improvements.
The evaporator coil inside your air handler and the condenser coil in your outdoor unit are critical components of your Houston HVAC system — and both are highly susceptible to contamination that reduces efficiency and can lead to costly mechanical failure. In Houston's pollen-heavy spring and fall seasons, outdoor condenser coils can become densely coated with pollen, cottonwood seeds, and debris within weeks. Indoor evaporator coils accumulate mold, bacteria, and dust that bypass the air filter, reducing heat exchange efficiency and contributing directly to poor indoor air quality.
Houston Air Duct Nova performs professional evaporator coil cleaning using no-rinse coil cleaner formulations approved for residential HVAC systems, applied with proper technique to penetrate coil fins and remove biological contamination without damaging delicate fin structure. Condenser coil cleaning uses high-pressure water and commercial coil cleaner to restore full airflow through the outdoor unit — often recovering significant efficiency losses accumulated over one or more Houston cooling seasons.
A dirty evaporator coil running in Houston's summer humidity is also a significant mold factory — moisture condensing on a contaminated coil provides ideal conditions for biological growth that then disperses into the air stream. Professional coil cleaning eliminates this contamination source. Many customers report noticeable improvement in cooling performance and reduced utility bills following combined coil and duct cleaning service.
Commercial and industrial HVAC systems in Houston face the same contamination challenges as residential systems — amplified by building scale, occupancy density, and often the continuous operation schedules that don't allow maintenance during business hours. Houston Air Duct Nova's commercial services division handles office buildings, retail centers, restaurants, medical facilities, schools, apartment complexes, warehouses, and industrial facilities across the greater Houston area with equipment and protocols scaled to commercial system specifications.
Our commercial duct cleaning service follows NADCA ACR standards for commercial applications, which specify minimum cleaning verifications including vacuum pressure measurements and post-cleaning visual inspections that meet NADCA published criteria. We work with building owners, property managers, and facility directors to schedule cleaning during off-hours, weekends, or in phased sections to minimize disruption to building operations. Our commercial team includes project managers experienced in the logistics and documentation requirements of commercial cleaning contracts.
We provide comprehensive commercial service documentation including pre-service system condition reports, cleaning process records, post-service verification documentation, and NADCA-compliant service certifications that property managers can provide to building owners, tenants, or regulatory inspectors. For Houston food service establishments, our documentation is formatted to support health department inspection requirements relating to ventilation system maintenance.

Honest answers to the questions Houston homeowners ask most often before scheduling their first air duct cleaning service.
NADCA recommends professional air duct cleaning every 3 to 5 years for typical residences. However, Houston's high humidity, year-round pollen, and long AC season mean Houston homes often benefit from more frequent cleaning — particularly those with pets, occupants with allergies or asthma, older home construction, or duct systems that have never been professionally cleaned. Our free inspection will assess your specific system's current condition and give you a personalized recommendation.
Common indicators include: visible dust or debris coming from supply registers when the AC turns on; a musty or stale odor when the HVAC system runs; allergy symptoms noticeably worse inside your home than outside; visible mold growth inside or near vent covers; a significant increase in dust settling on furniture and surfaces; reduced airflow from one or more registers; and a history of water intrusion near ductwork. Homeowners who've just purchased an older Houston home or completed a renovation also benefit strongly from professional cleaning before occupancy.
Professional air duct cleaning performed to NADCA standards is genuinely effective — but the duct cleaning industry has a documented history of companies selling "cleaning" with inadequate equipment that delivers no meaningful benefit. The critical difference is equipment: professional truck-mounted vacuum systems versus portable shop-vac units, and mechanical agitation to dislodge compacted contamination versus suction alone. Houston Air Duct Nova uses professional truck-mounted equipment and NADCA-trained technicians, and we provide before and after photographic documentation so you can verify the actual difference our service made — not just take our word for it.
A thorough, professional duct cleaning for a typical Houston single-family home — including initial inspection, system setup, mechanical cleaning of all duct runs and registers, sanitizer application, and final documentation — takes approximately 3 to 5 hours for a 2,000–3,000 square foot home. Larger homes, more complex duct systems, or systems requiring mold remediation will take longer. We never rush the cleaning process, because incomplete cleaning is ineffective cleaning. We'll provide a time estimate during our initial inspection so you can plan accordingly.
Clean duct systems allow your HVAC equipment to operate at designed airflow rates, which improves efficiency and can reduce energy consumption — particularly when combined with coil cleaning. Severely restricted ductwork and contaminated evaporator coils force your system to run longer cycles to achieve the same cooling effect, which translates directly to higher electricity bills during Houston's long cooling season. Many Houston customers report noticeable improvements in system performance and comfort after combined duct and coil cleaning service.
Yes, comprehensively. Houston Air Duct Nova holds all required Texas contractor licenses applicable to our scope of work, maintains $2 million general liability insurance coverage, and carries workers' compensation coverage for all employees. Every technician on our team holds current NADCA certification — the recognized professional standard for the duct cleaning industry. We provide proof of insurance and licensing to any customer upon request, and we encourage Houston homeowners to verify these credentials for any contractor they invite into their home.
No. Our service rates are consistent regardless of when you need us. A Saturday night emergency call carries the same rate structure as a Tuesday afternoon appointment. We believe emergencies don't follow a schedule, and we won't penalize Houston homeowners for needing help outside traditional business hours. Our 24/7 availability is genuinely unrestricted and no overtime surcharges are applied to after-hours or weekend calls.
