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.

AfterAir Duct Cleaning in Round Rock, TX
HVAC cleaning in Round Rock typically runs $280-$520 for a whole-home system, with most jobs scheduled within a week during cedar season. We’re CleanRun Duct Repair & Cleaning, and our crews work Round Rock homes built during the Dell-era boom - the same tract homes in Forest Creek, Stone Canyon, and Teravista whose flex ductwork is now 15-25 years old and has never been professionally cleaned. Every job starts with a written price before a panel comes off, and every duct run is photographed before and after. Call (737) 252-1285 for a free estimate.
Why Round Rock Homes Are Different
Round Rock’s housing stock is dominated by slab-foundation suburban tract homes built between 1993 and 2010, nearly all with flex ductwork routed through unconditioned attics. Those attics routinely exceed 140°F in summer, accelerating duct liner degradation and seal failure. The original Dell-era homeowners are selling now, and pre-listing inspections are surfacing duct systems that have never been professionally cleaned in 20-25 years.
The December through February mountain cedar bloom - locals call it “cedar fever” - deposits microscopic Ashe juniper pollen throughout duct interiors. This allergenic event is specific to the Austin-Round Rock corridor and creates a predictable post-season demand that doesn’t exist in Dallas or Houston. In older subdivisions like Forest Creek and Cat Hollow, technicians frequently find original galvanized trunk lines paired with later-added flex branch runs, a patchwork system that traps pollen and construction dust at every transition joint.
Our Main Round Rock Services
Most Round Rock homeowners who call us need one of these three services:
Air Duct Cleaning in Round Rock
We clean the complete duct system - supply and return runs, trunk lines, and plenum - using negative-pressure extraction with Rotobrush and Nikro equipment. In Round Rock, we pay special attention to transition joints in phased-build neighborhoods where flex meets galvanized, since that’s where cedar pollen and construction dust compact over years. Every run is photographed before and after. Air Duct Cleaning in Round Rock
Dryer Vent Cleaning in Round Rock
Dryer vent cleaning removes lint buildup from the appliance through the exterior termination. Round Rock’s hard water and heavy dryer use in large suburban homes create faster accumulation than the manufacturer-recommended annual cleaning can keep pace with. We verify airflow at the exterior hood and photograph the full run. Dryer Vent Cleaning in Round Rock
Duct Repair & Sealing in Round Rock
Duct repair addresses separated joints, crushed flex runs, and failed seals that leak conditioned air into 140°F attics. We use mastic sealant and mechanical fasteners, not tape, and test with a duct blaster when repair is complete. In Dell-era homes, we often find original seals that have dried and failed after two decades of heat cycling. Duct Repair & Sealing in Round Rock

BeforeAfterHVAC Cleaning in Round Rock
HVAC cleaning in Round Rock targets the components that actually move and condition air - the evaporator coil, blower assembly, condenser, and air handler - not just the ducts that carry it. With AC systems running roughly nine months per year and cycling far greater annual air volume than northern markets, these components accumulate debris faster here than almost anywhere in Texas. The mountain cedar pollen that coats Round Rock each winter embeds in wet coil fins and blower vanes, reducing efficiency and recirculating allergen loads until physically removed. HVAC Cleaning is our most requested service in the February through April window, when homeowners notice the smell of stored pollen on first warm-day startup.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on refrigerant lines, weak airflow from registers, or musty odor on AC startup after winter shutdown.
What it costs in Round Rock
Evaporator coil cleaning typically runs $180-$340 depending on accessibility and contamination level.
How we do it
We remove the access panel, apply foaming cleaner to the coil fins, rinse with low-pressure water, and photograph the before and after condition.
Blower Cleaning
Signs you need it
Vibration noise from the air handler, uneven airflow room-to-room, or dust puffing from registers when the fan cycles on.
What it costs in Round Rock
Blower cleaning typically runs $140-$260 for standard residential units.
How we do it
We remove the blower assembly, clean the squirrel cage and housing with compressed air and solvent, balance the fan, and reinstall with torque verification.
What HVAC Cleaning Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower cleaning | $140-$260 |
| Condenser cleaning | $120-$220 |
| Full HVAC cleaning (coil + blower + condenser) | $280-$520 |
How do I know my HVAC components are actually dirty?
We photograph every component before touching it - the coil, blower, and condenser - and deliver those images with the written invoice. If the camera shows clean fins, we don’t sell cleaning.
Can HVAC cleaning reduce my summer electric bill in Round Rock?
Yes - a debris-coated coil or unbalanced blower can increase runtime 15-25% in 100°F weather. After cleaning, most Round Rock homeowners see measurable improvement in cycle length within the first billing period.
Air Quality & Sanitizing in Round Rock
The mountain cedar event is only part of the problem; the real issue is organic material that accumulates year-round in Dell-era duct systems and finds moisture during shoulder-season humidity spikes. Air Quality & Sanitizing gives homeowners a documented, chemical-specific treatment record rather than a verbal assurance.
Mold Treatment
Signs you need it
Visible black or gray spotting on register fins, musty odor that intensifies when AC first cycles on, or recent water intrusion in the attic.
What it costs in Round Rock
Mold treatment typically runs $220-$480 depending on affected duct length and accessibility.
How we do it
We apply EPA-registered antimicrobial through the duct system using a fogging manifold, let it dwell per manufacturer spec, then extract residue with negative-pressure vacuum.
UV Light Installation
Signs you need it
Recurring mold after professional cleaning, family members with immunocompromised conditions, or chronic respiratory symptoms that improve when away from home.
What it costs in Round Rock
UV light installation typically runs $380-$650 including the lamp, ballast, and electrical connection.
How we do it
We mount a Honeywell or Aprilaire UV-C lamp downstream of the coil with a sight-glass port, wire to the blower circuit, and verify irradiance with a meter.
What Air Quality & Sanitizing Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Mold treatment | $220-$480 |
| Bacteria sanitizing | $180-$340 |
| UV light installation | $380-$650 |
Does UV light actually prevent mold in Round Rock’s humidity?
UV-C at 254 nanometers kills mold spores and bacteria that pass through the irradiated zone, but it does not clean existing debris - we treat first, then install UV as maintenance.
What chemicals do you use for sanitizing?
We use EPA-registered antimicrobials from Guardsman and Abatement Technologies, and we list the specific product by name on your written scope before application.
