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.

AfterSupply Duct Cleaning in Schertz, TX
Supply duct cleaning focuses specifically on the duct runs that carry conditioned air from your HVAC system outward to every room in your home – the pressurized side of the system that pushes air through your registers. In Schertz, TX, where summer heat means your system runs hard for eight or nine months of the year, those supply ducts accumulate dust, construction debris, allergens, and in older homes, biological growth at a rate that surprises most homeowners when they see the before photos. A full supply duct cleaning from CleanRun runs $280 to $520 for most Schertz homes, and every job starts with our Air Duct Cleaning services with a written price before a single panel comes off.
Supply ducts are not the same as return ducts, and cleaning them is not the same job. Supply runs operate under positive pressure, which means whatever is sitting inside them gets pushed directly into your living space every time the system kicks on. If you have been noticing reduced airflow from certain registers, fine dust settling within hours of cleaning your furniture, or musty odors that appear only when the air conditioning runs, the supply side of your duct system is the most likely place to start looking. CleanRun has been documenting exactly this on Schertz jobs since 2013 – Video Inspection first, findings photographed, written scope delivered before work begins.
This page covers everything specific to supply duct cleaning: what the process looks like, what it costs in Schertz, and what you receive as a documented deliverable when the crew leaves.

When You Need Supply Duct Cleaning
Supply duct contamination does not always announce itself with a single obvious symptom. More often it builds gradually – the kind of slow decline that’s easy to attribute to allergies or an aging filter. These are the scenarios CleanRun technicians most commonly document on Schertz jobs:
- Dust returns within 24 to 48 hours of cleaning. When supply ducts are carrying a heavy debris load, fine particulate gets deposited on every flat surface in a room during normal operation. If you’re cleaning the same surfaces repeatedly and the dust is back by the next morning, the air coming out of your registers is the source, not your housekeeping.
- Uneven airflow across rooms. Schertz homes built between 1995 and 2010 frequently show partial blockages at the first or second elbow of a supply run – a spot where construction dust, insulation fragments, or drywall particles collect over time. One room runs cold, another stays warm, and the thermostat takes the blame when the real problem is a restricted duct.
- Musty or stale odors only when the system runs. An odor that appears when the blower turns on and fades when it shuts off is almost always originating inside the supply system. In Schertz’s climate, where high humidity from late spring through September keeps condensation forming inside insufficiently insulated duct runs, biological growth at joints and elbows is a documented finding on a meaningful percentage of jobs.
- Recent renovation or construction work. If drywall, tile, or flooring work was done anywhere in the house while the system was running – or even powered off with registers open – supply ducts almost certainly caught debris. Drywall dust in particular packs into duct elbows and coats supply plenum walls in a way that does not resolve without mechanical agitation and negative-pressure extraction.
- A home that sat vacant or had deferred HVAC maintenance. Schertz sees its share of homes that were investor-owned or sat between sale and occupancy for several months. During that time, systems often run unfiltered or with a degraded filter. The camera record on these jobs tends to show the heaviest buildup CleanRun technicians document.
- Visible debris at the register face or inside the boot. You can pull a register cover and shine a flashlight into the boot – the short metal collar that connects the register to the duct run. If you see matted debris, discoloration, or biological growth within the first six inches, the rest of the run is worth inspecting. This is exactly where CleanRun’s pre-job camera documentation starts.
Our Supply Duct Cleaning Process
CleanRun’s process on a supply duct cleaning job is sequential and documented at each stage. There is no shortcut version and no abbreviated job sold at a lower price – every step below happens on every job, or the job does not start.
- Written scope and price before work begins. Haven Standard Clause 1: the written price is delivered before any access panel comes off or any equipment enters the home. The scope names every supply run being cleaned, identifies the equipment being used, and states the price in full. You approve the document before any work starts. “Call for a quote” does not exist at CleanRun – the written price is the quote.
- Pre-cleaning camera inspection and photo documentation. A technician runs a camera through each supply run before any cleaning equipment is introduced. The findings are photographed – debris accumulation, biological growth, collapsed liner, disconnected joints, whatever the camera shows. These before photos are part of the job record you receive at the end of the visit. This is the practice CleanRun has held since the first job in 2013, and it exists so you can see the difference between real cleaning and vacuum noise.
- Negative-pressure setup at the supply plenum. A negative-pressure collection unit – equipment from Nikro’s professional line – is connected at the supply plenum, which is the main distribution chamber that feeds all the supply runs. Negative pressure means the system is pulling air and debris toward the collection point rather than pushing contamination further into the duct network or back into the home. This setup is maintained throughout the cleaning.
- Mechanical agitation of each supply run. With negative pressure established, a technician works through each supply run from the register end using Rotobrush equipment – rotating brush heads that mechanically dislodge debris from duct walls, elbow interiors, and boot collars. The Rotobrush system is designed for duct work; it is not a modified shop vacuum or a generic tool. Agitation and extraction happen simultaneously, so loosened debris is captured at the plenum rather than redistributed.
- Boot and register cleaning. The boot – the short collar connecting the register to the duct run – is one of the heaviest debris accumulation points on any supply system. Each boot is wiped and vacuumed separately before the register cover is reinstalled. Register covers are cleaned at the same time. Technicians do not reinstall a dirty register over a clean duct.
- Post-cleaning camera verification and photo record delivery. After every supply run has been cleaned, the camera goes back through each one. After photos are taken at the same reference points as the before photos. Both sets – before and after – are compiled into the documented photo record delivered to you at the end of the job. If the after photos do not show a clear improvement over the before photos, that is a conversation CleanRun has with you before the crew leaves, not a week later. Every job is backed by the 365-Day Done Right Promise: if the work is not right, CleanRun makes it right, in writing.
BeforeAfterSupply Duct Cleaning Pricing in Schertz
Supply duct cleaning in Schertz, TX runs $280 to $520 for most single-family homes. The range exists because the variables that drive labor time are real: the number of supply runs, the age and layout of the duct system, the degree of contamination the camera documents, and whether any additional work – sanitizing, minor sealing at joints – is needed. Here is how those variables break out in practice:
| Home / System Profile | Typical Supply Duct Cleaning Range |
|---|---|
| Smaller home, 1,200-1,800 sq ft, single system, 8-12 supply runs | $280 – $360 |
| Mid-size home, 1,800-2,800 sq ft, single system, 12-18 supply runs | $340 – $440 |
| Larger home, 2,800-4,000 sq ft, or dual-system, 18-26 supply runs | $420 – $520 |
| Heavy contamination surcharge (documented by camera – construction debris, biological growth, or collapse) | $60 – $120 added to base |
| Antimicrobial sanitizing application to supply runs (optional, Honeywell-certified product) | $80 – $140 added to base |
Every price in that table is a written number on a scope document, not an estimate subject to revision once work starts. CleanRun has operated this way under Haven Standard Clause 1 since 2013, across more than 52,000 homes served. The price on the written scope is the price on the invoice.
If you have a written estimate from another company, bring it. CleanRun offers a Free Second Opinion on any written estimate – a CleanRun technician puts a written number next to the competitor’s number, and you decide. There is no charge for the comparison and no pressure attached to it.

FAQs – Supply Duct Cleaning
What is the difference between supply duct cleaning and return duct cleaning?
Supply ducts carry conditioned air from the HVAC system to your rooms; return ducts carry room air back to the system for reconditioning. Cleaning them involves different access points, different pressure configurations, and in many homes, different contamination profiles. Supply runs tend to accumulate finer particulate and construction debris, while return ducts – which pull air in – are more likely to show heavy dust matting and filter bypass debris near the return plenum. A full home duct cleaning job addresses both sides; a supply-only job is appropriate when the camera documents that the return side is in acceptable condition and the supply runs are the specific source of the problem. CleanRun’s pre-job inspection determines which scope is right before a price is written. Call (830) 402-5110 for a written quote for your home.
How long does supply duct cleaning take in a typical Schertz home?
Supply duct cleaning on a mid-size Schertz home – roughly 1,800 to 2,800 square feet with one system and 12 to 18 supply runs – takes two to three hours from equipment setup to final camera documentation. Larger homes with dual systems or heavily contaminated runs add time; the pre-job camera inspection gives CleanRun a realistic picture of what the job involves before the written scope is issued, so the time estimate in the scope reflects what the camera actually shows. No job is quoted by square footage alone – duct count, layout, and condition all factor in.
Is supply duct cleaning safe for flex duct systems common in Schertz?
Flex duct – the corrugated, insulated tubing used in most Schertz homes built after the mid-1990s – requires a different agitation technique than sheet metal. Rotobrush equipment includes flex-duct-specific brush profiles that clean the inner liner without applying the lateral pressure that tears or collapses corrugated walls. The pre-job camera inspection identifies the duct type in every run before cleaning equipment is selected. If a run is already partially collapsed or the liner is compromised, that finding is documented, disclosed in writing, and addressed through a separate duct repair scope – not ignored and cleaned over. Collapsed flex duct restricts airflow and harbors debris that no cleaning method fully resolves; the right answer in that case is documented repair, not a cleaning service that papers over a structural problem.
How often should supply ducts be cleaned in Schertz?
The National Air Duct Cleaners Association (NADCA) references a three-to-five year interval as a general baseline, but Schertz conditions modify that figure in practice. Homes in neighborhoods with active new construction nearby – areas like Fairway Ridge or portions of Schertz Parkway corridor that have seen sustained residential development – tend to show heavier debris accumulation than the baseline assumes, because construction particulate travels and enters HVAC systems even in finished homes nearby. Homes with pets, high occupancy, or a history of deferred filter maintenance follow a similar pattern. CleanRun’s camera record from a previous job gives you an objective baseline for scheduling the next one – the photo record tells you what the system looked like when it was last cleaned, so you’re not guessing at the interval. Call (830) 402-5110 to get a written scope and price for an inspection and cleaning.
