Professional Duct Cleaning Services in San Antonio
Your home's air ducts circulate thousands of cubic feet of air daily, but they also accumulate dust, pollen, pet dander, mold spores, and other contaminants. The average home accumulates 40 pounds of debris in its ducts annually. Every time your HVAC system runs, these contaminants circulate throughout your living space, impacting air quality and system efficiency. A-OK Services provides comprehensive duct cleaning services following NADCA (National Air Duct Cleaners Association) standards to remove accumulated contaminants and restore your system to peak performance.
Our TACLA29221C certified technicians use professional-grade truck-mounted vacuum systems and specialized tools to thoroughly clean all supply ducts, return ducts, trunk lines, and air handler components. We inspect your system with video cameras, provide before-and-after documentation, and sanitize ducts with EPA-approved antimicrobial treatments. Whether you need residential duct cleaning, commercial HVAC cleaning, or restaurant hood cleaning, we have the equipment and expertise to deliver exceptional results.

We invest in the best duct cleaning equipment available. Our truck-mounted HEPA vacuum systems create powerful negative pressure to capture all debris without releasing it into your home.

All equipment is regularly maintained and cleaned between jobs to ensure optimal performance and prevent cross-contamination.
Commercial Kitchen Hood Cleaning

Our certified technicians clean exhaust hoods, filters, ductwork, and fans to meet fire code requirements and insurance standards. We provide documentation for inspections and work during off-hours to avoid interrupting your operations.
Return Vent and Supply Duct Service

Complete Guide to Duct Cleaning in San Antonio
NADCA Standards and Professional Certification
NADCA-certified companies follow strict protocols for duct cleaning including complete system inspection, proper equipment, and cleaning all components—not just accessible parts.
The National Air Duct Cleaners Association (NADCA) sets industry standards for proper duct cleaning. NADCA-certified companies follow strict protocols including complete system inspection, cleaning all components (not just accessible parts), using proper equipment and techniques, preventing contamination during cleaning, and providing documentation of services performed. A-OK Services follows all NADCA standards to ensure thorough, safe, and effective duct cleaning. Beware of low-cost providers who only clean visible ducts or use inadequate equipment—proper duct cleaning requires truck-mounted vacuum systems (1000+ CFM), specialized brushes and tools, and trained technicians. The EPA recommends hiring NADCA members for duct cleaning services.
Health Benefits of Duct Cleaning
Professional duct cleaning reduces airborne particles by 40-60%, providing relief for allergy and asthma sufferers by removing accumulated pollen, dust mites, and mold spores.
Indoor air quality significantly impacts health, especially for children, elderly, and those with respiratory conditions. Dirty ducts circulate allergens, dust mites, pet dander, mold spores, bacteria, and viruses throughout your home. Studies show professional duct cleaning can reduce airborne particles by 40-60%, providing relief for allergy and asthma sufferers. San Antonio's high pollen counts (oak and cedar) make duct cleaning especially beneficial—pollen accumulates in ducts and recirculates for months after pollen season ends. If family members experience unexplained respiratory symptoms, headaches, or allergies that worsen at home, contaminated ducts may be the culprit.
Energy Efficiency and Cost Savings
Removing dust from HVAC coils can improve efficiency by 21%. Dirty ducts add $200-500 annually to cooling costs and cause premature system wear.
Dirty ducts force your HVAC system to work harder, reducing efficiency and increasing energy costs. The EPA estimates that removing even 0.042 inches of dust from heating and cooling coils can improve efficiency by 21%. Accumulated debris restricts airflow, causing systems to run longer to reach desired temperatures. For an average San Antonio home, this can add $200-500 annually to cooling costs. Additionally, dirty ducts lead to premature system wear and more frequent breakdowns. Regular duct cleaning extends HVAC lifespan, reduces energy consumption, and prevents costly emergency repairs. Most homeowners recover the cost of duct cleaning through energy savings within 18-24 months.
When to Clean Your Ducts
Clean ducts every 3-5 years, or immediately if you see visible mold, excessive dust, musty odors, or have completed major renovations.
NADCA recommends duct cleaning every 3-5 years for average homes, but San Antonio homes may benefit from more frequent cleaning due to high dust and pollen. Clean ducts immediately if you see visible mold growth inside ducts or on vents, notice excessive dust on furniture shortly after cleaning, detect musty odors when HVAC runs, have vermin infestation in ducts, experience unexplained respiratory symptoms, or completed major renovations (construction dust infiltrates ducts extensively). Also consider cleaning after moving into a previously owned home—you don't know when previous owners last cleaned ducts or what contaminants may be present.
Commercial Duct Cleaning Services
Commercial duct cleaning includes rooftop units, VAV boxes, kitchen exhaust systems (required by fire code), and industrial ventilation with off-hours service.
Commercial buildings have unique duct cleaning needs. Office buildings, retail spaces, medical facilities, schools, and restaurants require specialized approaches. We provide commercial services including rooftop unit cleaning, VAV box cleaning, kitchen exhaust system cleaning (required by fire code), clean room and medical facility HVAC, and industrial ventilation system cleaning. We work off-hours to avoid disrupting business operations and provide detailed documentation for facility managers, building inspectors, and insurance compliance. Commercial duct cleaning frequency depends on occupancy, activities, and regulatory requirements—restaurants need quarterly hood cleaning, while offices typically need cleaning every 3-5 years.
Duct Cleaning and Air Purifiers
Clean ducts maximize air purifier effectiveness. Install HEPA filters or UV lights after duct cleaning for maintained air quality between professional services.
Duct cleaning works synergistically with air purification systems. Clean ducts maximize air purifier effectiveness by removing accumulated contaminants that overwhelm filtration systems. We recommend cleaning ducts before installing new air purifiers or HEPA filters to ensure optimal performance from day one. After cleaning, adding UV lights, HEPA filters, or whole-home air purifiers maintains clean air and extends time between cleanings. However, air purifiers cannot replace duct cleaning—they filter circulating air but don't remove debris stuck to duct walls, in bends, or in less-accessible areas.
San Antonio Climate Considerations
San Antonio's high humidity, oak/cedar pollen, and long cooling season make regular duct cleaning especially valuable for maintaining indoor air quality.
San Antonio's climate creates specific duct cleaning challenges. High humidity promotes mold and mildew growth in ducts, especially in rarely used rooms or on oversized AC systems that don't run long enough to dehumidify. Oak and cedar pollen seasons dump massive amounts of allergens into homes—these accumulate in ducts and continue circulating for months. South Texas dust and occasional sandstorms introduce fine particles that penetrate homes and settle in ductwork. Our long cooling season (April-October) means AC systems run extensively, circulating more air (and contaminants) than in northern climates. These factors make regular duct cleaning especially valuable for San Antonio homeowners.
What to Expect During Service
Professional duct cleaning takes 3-5 hours and includes video documentation, truck-mounted vacuum cleaning, and antimicrobial treatment. Results are immediately noticeable.
Professional duct cleaning typically takes 3-5 hours for average homes. Our process: 1) Complete system inspection with video camera documentation. 2) Protect floors and furniture with drop cloths. 3) Create access points in trunk lines if needed. 4) Attach truck-mounted vacuum to main trunk line to create negative pressure. 5) Clean each supply and return duct using rotating brushes and compressed air. 6) Clean blower compartment, evaporator coil, and air handler. 7) Apply EPA-approved antimicrobial treatment if requested. 8) Seal access points and clean up. 9) Provide before/after video documentation and maintenance recommendations. You can remain home during service, though the vacuum truck will run outside. Most homeowners notice immediate improvement in air quality and reduced dust.

Duct Cleaning FAQs
How often should I clean my air ducts?
NADCA recommends duct cleaning every 3-5 years for typical homes. Clean more frequently (every 1-2 years) if you have pets, smokers, allergies, recent renovations, or live in high-dust areas. San Antonio's high pollen and dust levels often warrant more frequent cleaning than the national average.
How long does duct cleaning take?
Most residential duct cleaning takes 3-5 hours depending on home size, system complexity, and contamination level. Larger homes or severely contaminated systems may take 6-8 hours. Commercial duct cleaning varies widely based on building size and system configuration.
Will duct cleaning damage my ducts?
No. Professional duct cleaning using proper NADCA-approved methods and equipment is completely safe. We use soft-bristle brushes designed specifically for ductwork and adjust vacuum pressure appropriately. Our technicians are trained to identify and avoid damaging flexible ducts, insulation, and connections.
How much does duct cleaning cost in San Antonio?
Residential duct cleaning typically costs $400-$800 for average homes (1,500-2,500 sq ft), depending on system size, number of vents, and contamination level. Larger homes or complex systems cost more. We provide free estimates after inspecting your specific system. Beware of "$99 whole house" deals—these are typically scams or bait-and-switch tactics.
Can duct cleaning help with allergies?
Yes. Duct cleaning removes accumulated allergens like pollen, dust mites, pet dander, and mold spores that circulate through your home. Many allergy sufferers report significant symptom relief after professional duct cleaning, especially during San Antonio's intense oak and cedar pollen seasons. Combine with HEPA filtration for maximum benefit.
Do you clean dryer vents too?
Yes! Dryer vent cleaning is a critical fire safety service. Lint buildup causes 15,000+ house fires annually. We clean the entire dryer vent system from the dryer to the exterior exhaust, removing all lint accumulation. Dryer vents should be cleaned annually, or more often if you notice longer drying times.
Will I see immediate results after duct cleaning?
Most homeowners notice immediate improvement in air quality and reduced dust on surfaces. You may also notice improved airflow from vents, reduced HVAC noise, and less musty odor when the system runs. Energy savings accumulate gradually—expect to see lower utility bills over subsequent months.
Do you provide before and after documentation?
Yes. We use video camera inspection to document duct conditions before and after cleaning. This shows you exactly what was in your ducts and proves the thoroughness of our cleaning. We also provide written documentation of services performed, equipment used, and maintenance recommendations for your records.
