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 Leon Valley
Air duct cleaning in Leon Valley typically runs $350 – $650 for a full residential system and is scheduled by appointment with our San Antonio office dispatching crews locally. We’re familiar with the mix of mid-century ranch homes near the Leon Valley Golf Course and the newer subdivisions climbing the hills toward Ridgeview and Seneca, so we know what to expect before we arrive.
Our Air Duct Cleaning in Leon Valley crews drive the full system route regularly. Leon Valley’s position in the Balcones Escarpment transition zone means a 1960s ranch on the valley floor can have completely different duct conditions than a 2005 build two streets up. That’s not a detail you catch from a template quote. Call (361) 326-5060 and we’ll schedule a free estimate, usually within a few days.

We recently cleaned a 1960s ranch near the Leon Valley Golf Course where the original galvanized supply and return ducts were packed with tree debris and irrigation-driven humidity. Using a Rotobrush agitation tool under negative pressure with HEPA filtration, we pulled out the buildup, restored airflow at the registers, and advised the homeowner to move from filter-only maintenance to a professional clean every three years. We also recommended Duct Sealing in Leon Valley to prevent future humidity intrusion.
Air Duct Inspection in Leon Valley
Air Duct Inspection in Leon Valley is the first step for homeowners who suspect reduced airflow, musty odors, or uneven heating and cooling across rooms. Our technician runs a video camera through the supply and return lines, documenting debris levels, duct condition, and any moisture points where mold can take hold. In Leon Valley’s humid subtropical climate, we often find mold growth inside ductwork in older homes that have relied on filters alone for decades. An inspection typically costs $150 – $250 and includes a written report with photos.
When to Schedule
Book an inspection if your Leon Valley home hasn’t had ducts cleaned in ten years or more, if you’ve recently renovated, or if family members experience unexplained respiratory irritation. Homes near the Leon Valley Golf Course should consider inspection every two to three years due to accelerated debris loading from irrigation runoff and tree pollen.
What the Camera Reveals
Our video inspection identifies cracked flex duct, disconnected joints, and standing water in low points. These issues are common in Leon Valley’s 1950s – 1970s ranch stock with original galvanized or early flex installations. Finding them early prevents the spread of contaminants and protects your HVAC equipment from strain.
Residential Air Duct Cleaning in Leon Valley
Residential Air Duct Cleaning in Leon Valley removes accumulated dust, pollen, mold spores, and debris from the complete duct network serving your home. Our crew seals each register, applies negative pressure with a Nikro system, and uses Rotobrush rotary agitation to dislodge buildup at the source. The entire job is captured under HEPA filtration so nothing recirculates. A typical Leon Valley home runs $350 – $650 depending on system size, duct material, and contamination level.
Valley-Floor Ranch Homes
Older ranches near Bandera Road and the original Leon Valley core often have galvanized steel ducts that corrode internally and trap debris. These systems need thorough mechanical agitation. We price them individually after inspection because access points vary and some original installations lack sufficient cleanouts.
Hillside Subdivisions
Newer homes in Ridgeview and Seneca typically use flex duct with better initial design but still accumulate dust through normal use. The cleaning process is more straightforward, and these systems often respond well to standard rotary brush and negative-air extraction on a predictable schedule.
Trusted Brands We Service in Leon Valley
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for controlled debris removal, and filtration products from Honeywell, Aprilaire, and Guardsman. We stock common fittings and replacement filters for Leon Valley customers, so if our inspection turns up a crushed flex run or failed register boot, we can often address it during the same visit rather than rescheduling. The tools are professional-grade, not hardware-store gear, and we explain what each one does while it’s running so you understand what you’re paying for.
Common Air Duct Cleaning Problems We See in Leon Valley Homes
- Filter-only maintenance in older ranch homes. Many Leon Valley residents change filters regularly but never clean the ducts themselves. In 1950s – 1970s galvanized systems, debris and mold accumulate for decades behind what looks like clean filter changes.
- Golf course proximity accelerating contamination. Homes near the Leon Valley Golf Course face higher pollen loads, tree debris, and humidity from irrigation runoff. Ducts in these homes often need cleaning every three years instead of the standard five-to-seven.
- DIY modifications without permits. Leon Valley’s strong DIY culture means some homeowners have added registers, extended flex runs, or sealed joints with tape that degrades. These alterations create leak points that pull attic dust into the system.
- Contractors who don’t use negative pressure. Without source removal under controlled negative pressure, agitating duct debris simply blows it into your living space. We follow NADCA standards on every Leon Valley job to prevent this.
Pricing for Air Duct Cleaning in Leon Valley, TX
A typical full-system residential cleaning in Leon Valley runs $350 – $650. Smaller homes with straightforward flex-duct systems may fall at the lower end. Larger homes with multiple HVAC units, extensive galvanized duct, or significant contamination requiring extra agitation time run higher. Commercial systems are priced by square footage and unit count, typically starting around $800.
What moves the number: system size, duct material and accessibility, contamination level, and whether we find damage requiring repair during inspection. We do not quote per-vent. One flat price per system, agreed in writing before work starts. No add-ons at the door. Call (361) 326-5060 for a free estimate.

FAQs About Air Duct Cleaning in Leon Valley
Every three years is the realistic interval for homes near the Leon Valley Golf Course due to tree debris, pollen, and elevated humidity from irrigation runoff. Homes farther from the course with standard suburban exposure can typically go five to seven years. Call (361) 326-5060 to schedule an inspection and we’ll recommend a schedule based on your specific duct conditions.
NADCA standards require source removal of contaminants using mechanical agitation under controlled negative pressure, with HEPA filtration on the exhaust. For your Leon Valley home, this means debris is dislodged and captured, not blown through your vents. Our Nikro negative-air machines and Rotobrush systems meet this standard on every job.
Start with an Air Duct Inspection, which runs $150 – $250 and includes video documentation of your duct conditions. Many Leon Valley homes, especially mid-century ranches, have gone decades without cleaning due to the city’s strong DIY culture and strict permitting environment. The inspection tells you whether cleaning is needed now or can wait.
Yes, if they have ducted HVAC or dust collection systems. Rural properties around Leon Valley often have shop buildings with mini-splits or ducted units that accumulate dust from unpaved roads and open land. These systems need the same source-removal cleaning as your main house, priced individually after inspection.
Leon Valley’s humid subtropical climate produces year-round moisture that promotes mold growth inside ductwork, especially in older homes with original galvanized or flex duct. Long, hot summers mean constant HVAC operation, which circulates any mold spores or debris throughout living spaces. Professional cleaning removes the source and restores proper airflow.
