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.
Return Duct Cleaning in Schertz, TX
Return duct cleaning in Schertz typically runs between $120 and $280 depending on the number of return air grilles and the condition of the plenum – that’s the central chamber your return ducts feed into before air enters the air handler. Most Schertz homes can have the work completed in a single visit, and every job CleanRun our Air Duct Cleaning services handles starts with a written price before anything comes off the wall.
Return ducts are the half of your duct system that most companies skip, or vacuum at the grille and call it done. They pull air back from every room in the house and deliver it to the air handler for reconditioning. That means everything airborne in your home – pet dander, construction dust, dead skin cells, pollen blowing in from the Guadalupe River corridor – gets drawn through those ducts constantly, twelve months a year. In Schertz, where summers run long and systems run hard, that accumulation builds faster than most homeowners expect. When we photograph the inside of a return duct run that hasn’t been cleaned in four or five years, the camera typically shows a felt-like mat of grey debris coating the duct walls from the grille collar to the plenum elbow. That material doesn’t stay put. It gets pulled through the air handler, coats the evaporator coil, and ends up recirculating into your living space.
CleanRun has been photographing the inside of every duct run – before and after – since our first job in 2013. If you’ve had a competitor out and walked away with nothing but a receipt, call us at (830) 402-5110. We’ll give you a written second opinion at no charge. For a full picture of what’s involved in a complete system cleaning, see our Air Duct Cleaning in Schertz page – return duct cleaning is one documented piece of that larger scope.
When You Need Return Duct Cleaning
Return ducts don’t announce themselves the way a noisy supply grille does. The signs tend to show up elsewhere. Here’s what typically brings Schertz homeowners to us:
- A fine grey film that returns within days of dusting. If horizontal surfaces in your home are dusty again within 48 to 72 hours of cleaning, the return system is redistributing what it’s already collected. This is one of the most consistent patterns we see in homes along the FM 3009 and FM 78 corridors, where new construction brought with it years of drywall dust.
- Reduced airflow at supply registers after filter changes. A blocked return restricts how much air the blower can pull in. Rooms feel warmer or harder to cool even though the filter is fresh. The obstruction is usually further inside the duct, not at the grille itself.
- Allergy symptoms that don’t track with outdoor pollen counts. Schertz sits in a high-cedar-pollen zone, but if symptoms are worst indoors during times when outside counts are low, the return system is likely recirculating a stored allergen load.
- A musty odor that’s most noticeable when the system first kicks on. The first few seconds of airflow push whatever is sitting in the duct walls into the room. Musty or stale smells at startup almost always trace back to the return side, where humidity from Schertz summers condenses and creates the right environment for microbial growth.
- The system hasn’t been cleaned since the home was built or purchased. A significant portion of the Schertz housing stock was built between 2005 and 2022. If you bought a home in Homestead, Crossvine, or any of the Schertz-Cibolo corridor subdivisions and have never had the return ducts cleaned, the original construction debris is still in there.
- A recent renovation or addition. Drywall cutting, sanding, and painting generate fine particulate that the return system draws in continuously during the work. Without a temporary seal at the return grilles, that material distributes through the entire system.
Our Return Duct Cleaning Process

What follows is exactly what happens on a CleanRun return duct cleaning visit in Schertz – documented at every step.
- Written scope and price before work starts. Before any panel comes off and before any equipment enters the home, you receive a written price. This is Haven Standard Clause 1. There is no “we’ll know more once we get in there” pricing at CleanRun. If the camera finds something that changes the scope, we show you the photo and write a new number. You approve it or we stop.
- Pre-work photography of every return duct run. We pull each return grille and photograph the interior of the duct from the collar to as far as the camera reaches. These images are time-stamped and become part of your job record. This is what shows you what was actually there, not what we describe to you after the fact.
- Negative-pressure extraction setup. Negative-pressure extraction means we attach a high-volume collection unit – we use Nikro and Rotobrush equipment, depending on duct geometry – to the air handler side of the return plenum. This creates a contained vacuum that pulls dislodged debris toward the collection point rather than pushing it further into the system. The Nikro HEPA-filtered units we use keep particulate from escaping into the living space during the process.
- Mechanical agitation through every return run. A flexible rotary brush works through the length of each return duct run, dislodging debris that a shop-vac or simple suction cannot reach. For returns with longer runs or tight elbows – common in the two-story homes in Homestead and the Schertz 78154 zip code – we adjust brush diameter and cable length to reach the full run without damaging the duct liner.
- Plenum inspection and cleaning. The return plenum is the collection point for everything the return ducts carry. We inspect and clean the plenum interior, check the condition of the seal at the air handler connection, and note any gaps or disconnects that could be pulling unconditioned attic air into the system – a common finding in Schertz homes with attic-mounted air handlers.
- Post-work photography and written job record. After cleaning, we re-photograph every return run from the same positions as the pre-work shots. You get both sets. The job record includes the before images, after images, equipment used, scope completed, and the written 365-Day Done Right Promise. If something isn’t right within 365 days, we come back and make it right – in writing, not subject to manager approval.

AfterReturn Duct Cleaning Pricing in Schertz
How Much Does Air Duct Cleaning Cost? (2026 Price Guide) - Schertz, TX Return duct cleaning in Schertz is priced on scope – specifically, the number of return air grilles, the length and configuration of each return run, and the condition of the return plenum. Every price is written before work begins. “Call for a quote” is not how we operate.
| Scope | Typical Price Range |
|---|---|
| Single return grille (small home, one return) | $120 – $160 |
| 2-3 return grilles (standard Schertz single-story) | $160 – $220 |
| 4-6 return grilles (larger home, multi-zone, or two-story) | $220 – $280 |
| Return plenum cleaning (added to any of the above) | $40 – $80 |
| Heavy debris load or post-renovation condition | Add $30 – $60 per affected run |
Several factors move the number within those ranges. Return runs in Schertz homes built before 2010 are often flex duct – corrugated flexible tubing that accumulates debris in the ribbing along its length and takes longer to clean thoroughly than rigid sheet metal. Homes in Crossvine and the newer Schertz-area subdivisions tend to have more return grilles as part of multi-zone systems, which increases the scope but distributes the cost more predictably across a larger system.

FAQs – Return Duct Cleaning

What’s the difference between return duct cleaning and supply duct cleaning?
Supply ducts carry conditioned air from the air handler to each room in the house; return ducts pull room air back to the air handler to be reconditioned. Return ducts accumulate debris faster because they operate under suction – they draw in whatever is airborne in the living space. Supply duct walls tend to have lighter deposits because the airflow direction pushes material toward the registers rather than inward. Both sides need to be cleaned, but the return side is consistently dirtier when we Video Inspection photograph it, and it’s the side most frequently skipped by lower-cost operators. If you’re only cleaning one side, you’re leaving the dirtier half untouched. Call (830) 402-5110 for a written quote that covers both.
How often should return ducts be cleaned in Schertz?
For most Schertz homes, a three-to-five-year interval is reasonable under normal conditions. That range compresses to two to three years if you have shedding pets, if anyone in the household has respiratory sensitivities, or if the home went through any renovation work. Schertz’s climate also plays a role: the extended cooling season means the system runs more hours per year than it would in a northern climate, which accelerates accumulation. The camera tells you more than a calendar does – if pre-work photographs show significant debris, the cleaning is warranted regardless of how long it’s been.
Can return duct cleaning improve my HVAC system’s efficiency?
Yes, measurably, when the restriction is significant. A return duct lined with debris narrows the effective airflow cross-section, which means the blower works harder to pull the same volume of air. That shows up as longer run cycles, higher energy use, and uneven room temperatures. In Schertz homes where we’ve photographed a three-to-four-inch debris mat at the first elbow of the return run, clearing that restriction has let the air handler return to design airflow without any change to the equipment itself. We don’t make efficiency guarantees – there are too many variables in a complete HVAC system – but restricted airflow on the return side is a documented, photographable problem, and removing it has documented, photographable results.
Do you clean the return air grilles themselves, or just the ducts?
Both. Grille cleaning is part of the standard scope. Return grilles in Schertz homes accumulate a dense layer of lint, dust, and pet hair that reduces airflow before air even enters the duct. We remove, clean, and reinstall each grille as part of the process. If a grille is bent, corroded, or has a broken damper, we document that in the job record and note it for your attention – we don’t upsell a replacement on the spot, but you’ll have the information in writing.
Return Duct Cleaning as Part of a Complete System Service
Return duct cleaning is one documented component of a complete air duct system service. On its own, it addresses the return side of the airflow loop. Combined with supply duct cleaning, air handler cleaning, and dryer vent cleaning, it addresses the full system. Tomas Reyes and the CleanRun team have served Schertz homeowners since 2013 – more than 52,000 homes served across the service area, every one with a written price and a documented photo record. We’ve cleaned ducts in Homestead, Crossvine, Schertz Ranch, and throughout the 78108 and 78154 zip codes, and the return duct condition in Schertz homes built during the 2015-2022 construction boom is consistent: construction particulate at the plenum, flex-duct ribbing loaded with fine debris, and return runs that have never been photographed, let alone cleaned.
The CleanRun home page has a full picture of everything we service. If you want to understand the complete scope of what a documented duct cleaning looks like – not just the return side – our Air Duct Cleaning in Schertz page walks through the full process with the same level of detail.
