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 Lewisville, TX
Complete HVAC cleaning and air quality treatment in Lewisville typically runs $350-$850 for whole-system work, with most jobs scheduled within a week and finished in a single day. The lake-effect humidity from adjacent Lake Lewisville, combined with the city’s aging 1980s-1990s flex-duct housing stock, creates conditions we don’t see at the same rate in inland DFW suburbs. Our crews document every duct run with before-and-after photos, and every job starts with a written price agreed before any panel comes off. Call (469) 405-6133 for a free estimate.
Why Lewisville Homes Are Different
Lewisville sits immediately downwind of Lake Lewisville, one of the largest reservoirs in the DFW Metroplex. That proximity pushes ambient relative humidity measurably higher than in inland suburbs like Plano or Garland, and the effect is consistent enough that our technicians can predict it before opening a panel.
The city’s core residential buildout happened from the 1980s through the late 1990s, filling Lewisville with tract homes that almost universally used flexible ductwork rather than rigid sheet metal. After three-plus decades, those flex duct inner liners become brittle and fibrous, shedding particulates directly into the air stream. In neighborhoods along the Lake Lewisville shoreline corridor, we regularly pull duct systems with visible mold growth at return-air boots and flex-duct connections, even in homes with quality filters. The same builders’ identical floor plans located further inland don’t show this pattern at the same rate. That sustained humidity, paired with Lewisville’s intense cedar, oak, and Bermuda grass pollen seasons, accelerates both biological growth and particulate buildup inside aging duct systems.
Our Main Lewisville Services
Most Lewisville homeowners who call us start with one of these three services, each with its own dedicated local page.
Air Duct Cleaning in Lewisville
We clean the complete duct system, from return plenum (the box that collects air before it reaches your furnace) to every supply register, using negative-pressure extraction that pulls debris out rather than pushing it deeper. In Lewisville’s 1980s-1990s flex-duct homes, we’re especially careful at connection points where aging liners have become friable. Every run is photographed before and after.

Dryer Vent Cleaning in Lewisville
Lint accumulation in dryer vents is a fire hazard and efficiency killer, and Lewisville’s humid lake air causes lint to clump and stick more than in drier climates. We clean the full vent run from appliance to exterior termination, verify airflow with a meter, and document the condition. Dryer Vent Cleaning in Lewisville

Duct Repair & Sealing in Lewisville
Aging flex-duct liners in Lewisville homes crack, sag, and separate at joints, dumping conditioned air into attics and crawl spaces. We repair or replace damaged sections, seal connections with mastic, and test static pressure to verify the system holds. Duct Repair & Sealing in Lewisville

AfterHVAC Cleaning in Lewisville

North Texas HVAC systems run six or more months per year, but Lewisville’s lake-proximity keeps overnight dew points elevated even during summer, meaning conditioned air inside ducts encounters higher moisture loads than the regional average. That sustained humidity accelerates biological growth on coils and in air handlers, particularly in homes with the city’s characteristic 1980s-1990s flex-duct construction. Our HVAC Cleaning service targets these components directly, with documented photo records showing what the lake microclimate has produced inside your system.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on the coil, reduced airflow from vents, or a musty smell when the AC first cycles on in Lewisville’s humid months.
What it costs in Lewisville
Evaporator coil cleaning typically ranges $180-$340 in Lewisville, depending on accessibility and contamination level.
How we do it
We remove the access panel, apply foaming cleaner formulated for aluminum fins, rinse with low-pressure water, and photograph the coil condition before and after.
Blower Cleaning
Signs you need it
Uneven heating or cooling across rooms, a blower wheel that rattles or vibrates, or dust streaking from supply registers in Lewisville’s pollen-heavy seasons.
What it costs in Lewisville
Blower assembly cleaning typically ranges $160-$290 in Lewisville.
How we do it
We remove the blower assembly, clean the wheel and housing with compressed air and solvent, balance the wheel, and reinstall with fresh hardware.
What HVAC Cleaning Costs in Lewisville
| Item | Typical range in Lewisville |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower assembly cleaning | $160-$290 |
| Full HVAC system cleaning (coil, blower, air handler) | $450-$750 |
How do I know if my HVAC needs cleaning or just my ducts?
If you smell must when the AC kicks on, see ice on the coil, or have uneven temperatures room-to-room, the HVAC components need direct attention beyond duct cleaning. Call (469) 405-6133 and we’ll inspect both systems and put a written price to each option.
Can HVAC cleaning reduce my summer electric bill in Lewisville?
A dirty coil or blower forces the system to run longer to hit the thermostat setpoint, and in Lewisville’s extended cooling season that adds up. Cleaning restores designed airflow and heat transfer efficiency.
Air Quality & Sanitizing in Lewisville

The same lake-effect humidity that drives mold growth in Lewisville ductwork creates ideal conditions for bacterial colonization and persistent odors in HVAC systems. Homes in the 1980s-1990s build areas are particularly susceptible because aging flex-duct liners provide fibrous surfaces for biological attachment that newer rigid-metal systems don’t offer. Our Air Quality & Sanitizing service treats these problems at the source, with application methods and products selected for the specific contaminants the lake microclimate produces.
Mold Treatment
Signs you need it
Visible growth at return-air boots, a persistent earthy smell when the system runs, or recent water intrusion in Lewisville’s storm-prone spring seasons.
What it costs in Lewisville
Whole-system mold treatment typically ranges $400-$800 in Lewisville, depending on extent and accessibility.
How we do it
We apply an EPA-registered antimicrobial through the duct system using a fogging device, treat affected surfaces directly, and verify with post-treatment photos.
UV Light Installation
Signs you need it
Recurring mold despite cleaning, allergy symptoms that worsen when the HVAC runs, or a system located in a humid attic or crawl space common in Lewisville’s older homes.
What it costs in Lewisville
UV-C lamp installation typically ranges $350-$650 in Lewisville, including lamp and electrical connection.
How we do it
We mount a UV-C lamp in the supply plenum near the coil, wire to the blower circuit for automatic operation, and verify irradiance with a meter.
What Air Quality & Sanitizing Costs in Lewisville
| Item | Typical range in Lewisville |
|---|---|
| Mold treatment (whole system) | $400-$800 |
| UV-C lamp installation | $350-$650 |
| Combined air quality package (treatment + UV) | $650-$1,100 |
Will mold treatment damage my flex ducts?
We select application methods and dwell times specifically for flexible ductwork, and we inspect liner condition before treating. Brittle liners are noted in the written scope and discussed with you before proceeding.
How long does UV light take to work?
Surface mold at the coil and plenum begins declining within 48-72 hours of installation, but the lamp’s real value is prevention of recurrence in Lewisville’s humid conditions.
