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
Whole-system HVAC cleaning in Round Rock typically runs $450-$850 for a single-family home, with most jobs scheduled within a week and completed in one day. The city’s Dell-era housing boom left behind thousands of homes with builder-grade flex ductwork now aging out in 140°F+ attics, while the Balcones Escarpment position funnels record mountain cedar pollen straight into those same systems each winter. We dispatch crews from our Austin office to serve Round Rock directly, and every job starts with a written price before a panel comes off. Call (737) 259-5752 for a free estimate.
Why Round Rock Homes Are Different
Round Rock’s residential stock is overwhelmingly a single construction wave: the Dell Technologies-driven boom from roughly 1995 to 2015. Forest Creek, Teravista, and the Walsh Ranch area are filled with slab-on-grade tract homes where builder-standard flex ductwork was routed through unconditioned attics and left to bake. Those systems are now 15-25 years old, and the thermal cycling has taken a toll.
The city sits on the eastern edge of the Balcones Escarpment, squarely in Central Texas’s Ashe juniper pollen corridor. December through February brings “cedar fever,” some of the highest airborne allergen concentrations in the country. HVAC systems run near-continuously from May through September, then draw in extreme winter pollen loads. That combination accelerates filter clogging and interior duct contamination far faster than moderate climates. In the Dell-boom subdivisions on Round Rock’s east and northeast sides, we regularly find flex duct that has partially collapsed or pulled away from boot connections after years of thermal cycling, trapping debris and amplifying allergen recirculation in homes built between 1998 and 2008.
Our Main Round Rock Services
Round Rock homeowners call us most often for these three services:
Air Duct Cleaning in Round Rock
We clean the full duct network, from the plenum (the main distribution box) through every duct run to each register, using negative-pressure extraction to pull debris out rather than push it deeper. In Round Rock’s Dell-era homes, we regularly find 15-25 years of accumulated construction dust, pollen, and collapsed flex segments trapping contaminants. Every job includes a Documented Photo Record of every duct run, before and after. Air Duct Cleaning in Round Rock
Dryer Vent Cleaning in Round Rock
Lint accumulation in dryer vents is a leading cause of house fires, and Round Rock’s hard water and heavy dryer use in large households accelerate buildup. We clean the full vent run from appliance to termination, measure airflow before and after, and document the results. Dryer Vent Cleaning in Round Rock
Duct Repair & Sealing in Round Rock
The same thermal cycling that degrades flex ductwork in Round Rock’s superheated attics creates gaps, sags, and disconnected boots that leak conditioned air into unused spaces. We repair or replace damaged sections and seal connections with mastic and metal tape, then verify with a pressure test. Duct Repair & Sealing in Round Rock

BeforeAfterHVAC Cleaning in Round Rock
HVAC cleaning in Round Rock addresses the reality of systems that have run hard through fifteen to twenty summers of 100°F+ heat and drawn in some of the nation’s most concentrated winter pollen loads. The evaporator coils, blowers, and condensers in Dell-era homes are often coated with a matrix of fine dust, biological material, and hard water scale that restricts airflow and forces the system to run longer cycles. We treat this as a mechanical restoration, not a surface wipe, and we document every component with before-and-after photos as part of our standard deliverable. HVAC Cleaning covers our full process for homeowners outside Round Rock as well.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on the coil, weak airflow from registers, or the system running continuously without reaching set temperature.
What it costs in Round Rock
Evaporator coil cleaning typically ranges from $280 to $450 in Round Rock, depending on accessibility and contamination level.
How we do it
We remove the coil access panel, apply foaming cleaner formulated for aluminum fins, rinse with low-pressure water to avoid fin damage, and photograph the coil before reassembly.
Blower Cleaning
Signs you need it
Unbalanced airflow between rooms, vibration noise from the air handler, or dust puffing from registers when the system starts.
What it costs in Round Rock
Blower cleaning and balancing typically runs $220 to $380 in Round Rock.
How we do it
We remove the blower assembly, clean the squirrel cage and motor housing with compressed air and solvent, check amp draw, and reinstall with fresh vibration isolation.
What HVAC Cleaning Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Evaporator coil cleaning | $280 - $450 |
| Blower cleaning | $220 - $380 |
| Full HVAC cleaning (coil + blower + condenser) | $650 - $950 |
How do I know the HVAC cleaning was actually done?
Every component is photographed before and after, and those images are delivered as part of your job record under our Documented Photo Record standard, Haven Standard Clause 2. You see the coil, blower, and condenser state directly, not a verbal summary.
How often should HVAC cleaning happen in Round Rock?
Given the pollen load and continuous summer runtime, we recommend evaporator coil and blower inspection every three to four years, with cleaning as needed based on what the camera shows. Call (737) 259-5752 to schedule a look.
Air Quality & Sanitizing in Round Rock
Air quality and sanitizing in Round Rock targets the biological load that accumulates in aging flex duct systems positioned to capture extreme mountain cedar pollen and the mold-friendly humidity differentials created by 140°F+ attic temperatures. The same collapsed or gapped ductwork we find in Dell-era subdivisions creates stagnant zones where moisture and organic material support microbial growth, which the HVAC system then distributes throughout the home. We treat the source, not the symptom, and document with before-and-after photos. Air Quality & Sanitizing details our full protocol.
Mold Treatment
Signs you need it
Musty odor when the system runs, visible discoloration at registers, or aggravated respiratory symptoms during high-humidity months.
What it costs in Round Rock
Mold treatment for ductwork typically ranges from $450 to $750 in Round Rock, depending on extent and accessibility.
How we do it
We apply EPA-registered antimicrobial through the full duct network using a fogging system that reaches collapsed flex segments, then HEPA-vacuum loose debris and photograph every treated run.
UV Light Installation
Signs you need it
Recurring microbial growth after treatment, or a household member with immunocompromise or severe allergies.
What it costs in Round Rock
UV-C light installation at the coil or plenum typically runs $380 to $620 in Round Rock, including the Honeywell or Aprilaire unit.
How we do it
We mount a UV-C lamp at the evaporator coil or supply plenum, wire to the blower circuit for synchronized operation, and verify irradiance with a meter before closing the panel.
What Air Quality & Sanitizing Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Mold treatment (ductwork) | $450 - $750 |
| UV-C light installation | $380 - $620 |
| Full air quality package (treatment + UV + HEPA filtration) | $950 - $1,400 |
Does sanitizing eliminate cedar pollen from my ducts?
Sanitizing kills biological contaminants like mold and bacteria; physical pollen removal requires the mechanical agitation and negative-pressure extraction of duct cleaning first. We recommend cleaning before sanitizing for complete results.
Is the sanitizing solution safe for pets and kids?
We use EPA-registered, low-VOC products applied with the system off and fully ventilated before restart, with no residue left in occupied spaces. Call (737) 259-5752 to review the specific product sheet before booking.
