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.

AfterTrusted Air Duct Cleaning for San Antonio Homeowners
Air duct cleaning in San Antonio typically costs $450-$850 for a complete residential system and takes 3-5 hours for a thorough job. CleanRun Duct Repair & Cleaning has delivered written prices and documented photo records on every visit since 2013, serving more than 52,000 homes across Bexar County and the surrounding metro. Call (726) 600-7155 for a free estimate with a written price before any work starts.
San Antonio’s climate puts unique stress on ductwork. Our hot, dusty summers pull fine Hill Country soil through return vents, while spring oak pollen and cedar fever season layers allergens inside supply runs. In neighborhoods from Alamo Heights to Helotes, we’ve photographed buildup patterns that differ block by block - older Terrell Hills homes with original galvanized ducting collect corrosion flakes at elbows, while newer Live Oak construction often shows construction debris the original contractor never removed. We don’t guess at what your system needs. We inspect first, show you the images, and put the scope and price in writing before touching a single panel.
What Our Air Duct Cleaning Service Includes
Residential Duct Cleaning
Residential duct cleaning covers the complete network of supply and return runs, plenum (the central distribution box), and accessible trunk lines in a single-family home or townhome. In San Antonio, we typically find 2-4 years of accumulated dust, pollen, and pet dander in homes that have never been serviced, plus the occasional construction debris in builds from 2015-2025. CleanRun photographs every duct run before and after, delivers the images as part of your job record, and backs the work with our 365-Day Done Right Promise in writing.
Commercial Duct Cleaning
Commercial duct cleaning addresses the larger-volume HVAC systems found in office buildings, retail spaces, medical clinics, and multi-tenant properties throughout San Antonio’s medical center, downtown corridor, and growing Stone Oak business district. These systems move more air through wider trunk lines and often require scheduled after-hours service to avoid disrupting operations. CleanRun provides written scopes with line-item pricing for each air handler zone, coordinates with building engineers, and delivers timestamped photo documentation for facility maintenance records.
Supply Duct Cleaning
Supply duct cleaning targets the pathways that deliver conditioned air from your HVAC unit to each room’s register (the vent cover you see on floors, walls, or ceilings). When supply runs clog with debris, rooms at the end of long duct paths - common in sprawling San Antonio ranch-style homes in Castle Hills and Windcrest - receive weak airflow and uneven temperatures. CleanRun uses negative-pressure extraction (a vacuum system that pulls contaminants out while preventing them from entering your living space) on each supply run, with before-and-after photos showing the full length of the duct.
Return Duct Cleaning
Return duct cleaning clears the larger pathways that draw air back to your HVAC system for reconditioning. These ducts are the entry point for most household contaminants, and in San Antonio they often show the heaviest buildup because they lack the filtration that protects supply lines. We’ve found return plenums in Kirby and Leon Valley homes packed with a full inch of compacted dust, pet hair, and pollen that the homeowner’s standard 1-inch filter never caught. CleanRun’s process includes the return plenum, trunk, and each branch line, photographed and documented.
Full System Cleaning
Full system cleaning combines supply duct cleaning, return duct cleaning, and HVAC component cleaning into one coordinated scope - the plenum, evaporator coil, blower assembly, and accessible trunk lines. This is what most San Antonio homeowners actually need when they call for “air duct cleaning,” and it’s the only service CleanRun recommends without first inspecting your system. We deliver one flat price per system, agreed in writing before work begins, with the full photo record included.
Video Inspection
Video inspection uses a push camera to record the interior condition of duct runs that are otherwise inaccessible - behind finished walls, under slab foundations, or in tight attic spaces common in Alamo Heights and Monte Vista historic homes. The footage reveals corrosion, disconnected joints, pest intrusion, or construction debris that static photos cannot capture. CleanRun includes video inspection at no additional charge when our technicians determine it’s necessary to build an accurate scope, and we review the footage with you before finalizing the written price.

Brands We Service for Air Duct Cleaning
CleanRun’s equipment roster includes professional-grade systems from Rotobrush, Nikro, Abatement Technologies, and Guardsman - brands recognized in the HVAC trade for negative-pressure extraction and agitation tools that remove adhered debris rather than simply vacuuming loose surface dust. We’ve run Rotobrush systems in thousands of San Antonio homes and specify Nikro HEPA-filtered collection units for properties where occupant health sensitivity requires enhanced containment. Our technicians select equipment based on what your duct material, contamination type, and home layout actually require, not on what happens to be loaded that morning.
Whether your HVAC system is paired with Honeywell, Aprilaire, or any other make of air cleaner, humidifier, or ventilator, we can service the full assembly without voiding manufacturer warranties or compromising integrated controls. Our crews document the before-and-after condition of attached components as part of the standard photo record. If you have a specific brand concern, mention it when you call (726) 600-7155 and we’ll confirm compatibility before scheduling.
BeforeAfterSigns You Need Air Duct Cleaning Right Now
- Visible dust puffing from registers when the system cycles on. This means debris has accumulated to the point where airflow dislodges it, and what you see represents a fraction of what’s still adhered to duct walls. In San Antonio’s caliche-dust environment, this typically appears after 3-4 years without service.
- Uneven heating or cooling between rooms that share no obvious explanation. When one bedroom stays stubbornly warm while the rest of the house cools, a partial blockage in that room’s supply run is often the cause. We’ve cleared obstructions in Terrell Hills and Alamo Heights homes that restored balanced airflow without any HVAC repair.
- Persistent musty or stale odors that don’t respond to filter changes or surface cleaning. Ductwork can harbor mold spores, pest debris, or accumulated organic material that circulates whenever the blower runs. Our camera inspection identifies the source before we quote remediation.
- Increased allergy or respiratory symptoms among household members, especially during peak HVAC seasons. San Antonio’s year-round cooling means near-constant air circulation; without clean ducts, your system becomes a distribution network for pollen, dust mites, and microbial contaminants. We document allergen load reduction through photo evidence, not marketing claims.
- Recent renovation or construction work, even in a single room. Drywall dust, sawdust, and insulation particles enter return vents and settle in trunk lines, where they remain for years. In new construction areas like Selma and far Westover Hills, we’ve removed construction debris that builders never addressed.
Our Air Duct Cleaning Process - Step by Step
- 1
On-site inspection and photo documentation. Our technician arrives in a marked CleanRun vehicle, introduces themselves by name, and begins with a visual assessment of your registers, return grilles, and accessible HVAC components. We insert a borescope camera into representative duct runs to capture baseline images of contamination type and depth.
- 2
Written scope and flat-price quote delivered before any work begins. Haven Standard Clause 1 requires a written price agreed by the customer before a single panel is removed. Your quote specifies exactly which duct runs, plenums, and components are included, with one flat price per system - no per-vent add-ons, no equipment surcharges, no post-work invoice inflation.
- 3
Negative-pressure extraction with agitation tools matched to your duct material. We seal each register and create controlled suction at the central plenum, then use mechanical brushes or compressed-air whips to dislodge adhered debris for capture. Flexible ducting in newer Converse and Universal City homes receives gentler agitation than rigid metal ducting in 1970s Leon Valley builds.
- 4
Component-level cleaning of plenum, coils, and blower as specified in scope. The plenum - the sheet-metal box where supply and return trunks connect to your air handler - is opened, brushed, and vacuumed. When included in scope, we clean the evaporator coil and blower assembly to prevent recontamination of freshly cleaned ducts.
- 5
Post-cleaning photo record, system test, and written documentation delivered. Every cleaned run is photographed after completion. We run your HVAC system to verify balanced airflow and normal operation, then provide your complete job record: before-and-after images, scope summary, and 365-Day Done Right Promise documentation.
How Much Does Air Duct Cleaning Cost in San Antonio?
A typical residential full system cleaning in San Antonio runs $450-$850 for a single HVAC system up to 2,500 square feet. Smaller homes or partial cleanings (supply-only or return-only) generally fall in the $280-$450 range. Larger homes with multiple systems, extensive duct networks, or significant contamination requiring extended agitation time may reach $1,100-$1,400. Commercial properties are scoped individually based on air handler count and accessibility.
Several factors move the price within these ranges. Duct accessibility matters: homes with slab foundations and finished basements limit access to certain runs, while homes with attic or crawlspace trunk lines allow more efficient service. Contamination type affects time - light household dust clears faster than construction debris, pest remains, or compacted pollen layers. The number of registers and returns directly impacts scope; we count these during inspection and price accordingly, but never per-vent.
San Antonio’s market includes operators who advertise $79-$149 “whole house” specials, then add per-vent charges, equipment fees, and “required” sanitizing treatments that push the final invoice well above our upfront written price. CleanRun’s Haven Standard Clause 1 exists specifically to eliminate this bait-and-switch pattern. The price we write is the price you pay.

Frequently Asked Questions - Air Duct Cleaning in San Antonio
Air duct cleaning is the mechanical removal of accumulated dust, debris, allergens, and contaminants from the interior surfaces of your HVAC duct network, including supply runs, return runs, and the central plenum. In San Antonio homes, we typically remove fine caliche dust, oak and cedar pollen, pet dander, skin cells, and in older homes, corrosion particles and residual construction debris. The process does not involve applying chemicals or sealants unless specifically scoped and agreed in writing.
A thorough residential full system cleaning takes 3-5 hours for a typical single-system home up to 2,500 square feet. Larger homes, heavily contaminated systems, or properties with difficult access may extend to 6-8 hours. We do not rush the agitation and extraction phases to hit arbitrary time targets - the photo record confirms each run is cleaned to completion. You’ll receive a time estimate with your written price before work begins.
Residential full system cleaning in San Antonio typically costs $450-$850, with smaller or partial cleanings at $280-$450 and larger or more complex jobs reaching $1,100-$1,400.

Yes. CleanRun services duct systems connected to all major HVAC and air quality equipment brands, including Honeywell, Aprilaire, and any manufacturer whose components are integrated with your ductwork. Our process protects attached equipment and documents its condition before and after cleaning. If you have specific brand concerns, we verify compatibility during the initial inspection.
CleanRun does not advertise same-day or emergency dispatch for air duct cleaning, which is a scheduled maintenance service rather than an urgent repair. We do answer calls live 24 hours a day and can typically schedule inspections within 3-5 business days. If your situation involves an active HVAC failure or safety concern, we may recommend a qualified HVAC repair contractor before scheduling cleaning.
Every CleanRun job is backed by our 365-Day Done Right Promise: if the work is not right, we make it right, documented in writing on every invoice. This is not a manager-discretion policy but a written contractual obligation under the H.A.V.E.N. Standard. The promise covers workmanship and documentation accuracy for one full year from service completion.
Clear a path to your HVAC equipment and to at least one register in each room; remove fragile items from shelves near work areas where vibration may occur. You do not need to cover furniture or vacate the premises - our negative-pressure extraction contains debris at the collection point. We protect floors and surfaces as part of standard setup. Pets should be secured in a non-work area for their safety and our crew’s efficiency.
