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.
Air Duct Cleaning in Schertz, TX
Professional HVAC cleaning in Schertz typically runs $350-$650 for a complete system, with air quality treatments adding $200-$500 depending on scope. We’re CleanRun Duct Repair & Cleaning, and we dispatch crews to Schertz from our San Antonio office to handle the specific conditions this market presents: post-2005 tract housing with flex-duct runs baked in 130°F attics, caliche particulate compacted from construction dust, and a cooling season that stretches past nine months. Every job starts with a written price before any panel comes off, and every duct run is photographed before and after. Call (830) 549-6847 for a free estimate.
Why Schertz Homes Are Different
Schertz has been one of the fastest-growing communities in the San Antonio metro since the late 2000s, producing thousands of tract homes in master-planned subdivisions like Crossvine and Homestead where ductwork was sealed during framing and never professionally serviced. Most of this housing stock sits in the 5-15-year-old sweet spot where first-time duct cleanings are significantly overdue, and the large transient military population near JBSA-Randolph means many current owners have zero knowledge of prior HVAC maintenance history.
The dominant construction is post-2005 slab-on-grade by national builders such as D.R. Horton and Lennar, typically 2,000-3,000 sq ft with attic-mounted air handlers and flex-duct supply runs. Those attics routinely exceed 130°F in summer, baking construction drywall dust and caliche particulate into duct interiors during the first years of occupancy. The result is unusually compacted debris that requires more aggressive cleaning than older hard-pipe systems.
Schertz sits just south of the Balcones Escarpment and endures a nearly 9-month cooling season, keeping HVAC systems running almost continuously and accelerating debris accumulation far faster than in northern markets. The December-February Ashe juniper pollen season drives residents to seal homes and lean heavily on recirculating forced-air systems, loading return ducts with one of the region’s most notorious allergens. In subdivisions still under active buildout on Schertz’s northern and eastern edges, completed homes adjacent to graded lots regularly pull caliche dust and concrete particulate through return-air leaks during construction activity next door.
Our Main Schertz Services
Schertz homeowners call us most often for these three services, each with its own dedicated page:
Air Duct Cleaning in Schertz
We clean the full duct network, return plenum, and supply trunk lines in Schertz homes using negative-pressure extraction, which pulls loosened debris out through a sealed vacuum port rather than pushing it back into the living space. The flex-duct common in Crossvine and Homestead requires lower brush aggression than hard pipe to avoid tearing the liner. Every run is photographed before and after. Air Duct Cleaning in Schertz covers full pricing and scope.

Dryer Vent Cleaning in Schertz
Dryer vent blockages are common in Schertz’s newer subdivisions where long horizontal runs through slab-on-grade walls create lint traps at low points. We rotary-brush the full vent path and measure airflow before and after. The photo record shows the lint load removed. Dryer Vent Cleaning in Schertz has full details.

Duct Repair & Sealing in Schertz
Return-air leaks in Schertz homes pull attic dust and construction particulate directly into the system, visible on our cameras as heavy debris loading on the return side with clean supply runs. We seal leaks with mastic and mechanical fasteners, then pressure-test. Duct Repair & Sealing in Schertz explains the full process.

Before
AfterHVAC Cleaning in Schertz

Schertz’s nine-month cooling season and 130°F attics mean evaporator coils and blower assemblies work harder and foul faster than equipment in milder climates. The compacted caliche and construction dust in newer flex-duct systems also migrates upstream to coat coil fins and blower blades, reducing airflow and forcing longer run times. We treat HVAC cleaning as a system-wide job, not a single component wipe-down, and HVAC Cleaning covers our full equipment and method standards.
Evaporator Coil Cleaning
Signs you need it
Ice formation on the refrigerant lines, weak airflow from registers, or a 15-minute cooling cycle that used to run 8-10 minutes in Schertz’s July heat.
What it costs in Schertz
Evaporator coil cleaning in Schertz typically runs $180-$340 as a standalone service, or $120-$220 when bundled with a full duct cleaning.
How we do it
We remove the coil access panel, apply foaming cleaner that breaks down caliche and biological film without fin damage, rinse with low-pressure water, and photograph the coil surface before and after.
Blower Cleaning
Signs you need it
Vibration or rumble from the air handler cabinet, dust streaks on the filter face, or uneven airflow between rooms that worsens as the system runs.
What it costs in Schertz
Blower assembly cleaning in Schertz ranges from $150-$280, with squirrel-cage removal and balancing included in that figure.
How we do it
We remove the blower housing, clean each blade and the motor housing with compressed air and solvent, check belt tension if applicable, and bench-test for wobble before reinstalling.
What HVAC Cleaning Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Evaporator coil cleaning (standalone) | $180-$340 |
| Evaporator coil cleaning (bundled) | $120-$220 |
| Blower assembly cleaning | $150-$280 |
How do I know my HVAC system needs cleaning versus just the ducts?
If your registers blow clean but cooling cycles stretch longer each season, the coil or blower is likely fouled. We inspect both with a borescope during the initial assessment and show you the image before quoting. Call (830) 549-6847 for a free estimate.
Can HVAC cleaning reduce my summer electric bill in Schertz?
Yes, a clean coil and blower can improve system efficiency 10-15%, which matters when your AC runs 9+ months. We document before-and-after airflow readings in your job record. Call (830) 549-6847 to schedule.
Air Quality & Sanitizing in Schertz

Schertz’s sealed homes during cedar season and the recirculated air load from nine months of cooling create conditions where biological growth and persistent odors establish themselves in duct interiors. Military families rotating through JBSA-Randolph housing often inherit systems with unknown maintenance history, making documented sanitizing with photo verification especially valuable. Air Quality & Sanitizing details our full protocol standards.
Mold Treatment
Signs you need it
Musty odor when the system first kicks on, visible dark spotting on register faces, or allergy symptoms that spike within minutes of the blower starting.
What it costs in Schertz
Mold treatment in Schertz ranges from $250-$450 for spot application, or $400-$700 for full-system fogging with post-treatment lab verification.
How we do it
We collect tape-lift samples from three duct zones, apply EPA-registered fungistat to affected runs with an atomizing fogger, and photograph every treated surface before sealing the access.
UV Light Installation
Signs you need it
Repeated mold recurrence after cleaning, chronic condensation in the plenum, or a household member with immunocompromise who needs continuous air-stream sterilization.
What it costs in Schertz
UV-C lamp installation in Schertz runs $350-$600 including the lamp, ballast, and electrical connection to the air handler.
How we do it
We mount the lamp downstream of the coil with a sight-glass port, wire to the blower relay for automatic cycling, and show you the irradiance map for your specific model.
What Air Quality & Sanitizing Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Mold treatment (spot application) | $250-$450 |
| Mold treatment (full-system fogging) | $400-$700 |
| UV-C lamp installation | $350-$600 |
Is mold in Schertz ducts common because of the humidity?
Attic temperatures above 130°F actually suppress mold, but condensation at the coil and cool-down periods create microclimates where it thrives. We find it most often in systems with dirty coils and poor drainage. Call (830) 549-6847 for a borescope inspection.
Does UV light actually work, or is it a gimmick?
UV-C at 254 nanometers destroys mold and bacteria DNA, but only with proper intensity and dwell time. We size lamps to your air handler CFM and install with irradiance documentation, not a generic stick-on unit. Call (830) 549-6847 to discuss your system.
Brands We Service in Schertz
We stock parts and service equipment from Honeywell, Aprilaire, and Rotobrush, with most common filters, UV lamps, and sanitizing agents carried on every Schertz truck. Turnaround on ordered specialty items is typically 24-48 hours through our San Antonio parts coordination. See our brands for the full roster.
