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.

AfterFull System Cleaning in Lewisville, TX
Full system cleaning is a complete Air Duct Cleaning service that covers every component air moves through in your home – supply runs, return runs, the main plenum (the central distribution box your HVAC connects to), all registers, and the air handler cabinet itself. In Lewisville, a thorough full system cleaning typically runs $350 to $650 for a standard single-story home, with two-story homes and larger square footage ranging higher. Most jobs are completed in three to four hours, and every CleanRun technician leaves behind a documented photo record of every duct run – before and after – so you can see exactly what changed.
If you’ve had a quote from someone offering a “whole-house clean” for $79 or $99, that number reflects a shop-vac with an extension cord, not a full system cleaning. The difference is measurable: negative-pressure extraction using a Nikro or Rotobrush machine creates a sustained vacuum across the entire duct network, agitating debris at the source rather than redistributing it. That’s the distinction CleanRun has built its process around since 2013, across more than 52,000 homes served.

When You Need Full System Cleaning
A few situations make full system cleaning the right call rather than a Residential Duct Cleaning spot clean or a register-only service. Here are the most common ones we see in Lewisville:
- You’ve lived in the home more than four years without a documented duct cleaning. Lewisville’s climate runs HVAC systems hard – summer cooling runs from May through October, sometimes longer, and that’s a lot of airflow hours. Debris accumulates at elbows and transitions, and a full system cleaning addresses the entire network rather than the registers you can see.
- You’ve recently had construction or renovation work done. Drywall dust and insulation particles settle into duct runs quickly. In neighborhoods like Castle Hills and Southridge, we regularly find a visible debris line at the first elbow past any register that was left uncovered during a remodel – often a quarter-inch to a half-inch of fine particulate that a camera catches but a homeowner would never see otherwise.
- Allergy symptoms or respiratory issues that don’t improve with filter changes. When a 4-inch media filter isn’t keeping up, the problem is usually upstream – inside the plenum or in a return run that hasn’t been cleaned since the home was built.
- You’re buying or selling a home built between 2000 and 2015. Homes in this age range in Lewisville frequently have flex duct runs that have sagged or crimped over time. A full system cleaning includes a visual camera inspection of every run, so you know the condition of the ductwork before you close or list.
- Uneven heating or cooling across rooms. If the second-floor bedrooms in a two-story home near Vista Ridge are noticeably warmer than the main level, partial blockage in a supply run is often a contributing factor – one that shows up clearly in a camera pass.
- Musty or stale odors that cycle with the HVAC system. Odors that appear specifically when the system kicks on point to biological growth or accumulated organic debris inside the duct network. A full system cleaning removes the source material; sanitizing can follow if the camera confirms it’s warranted.
Our Full System Cleaning Process
Every step below happens on every job. Nothing is skipped based on the size of the quote.
- Pre-job camera inspection and written price delivery. Before a single panel comes off, the technician runs a camera through the accessible duct runs and photographs what’s inside. You see the before condition on the same visit. The written price is delivered at this point – Haven Standard Clause 1 means the number you see before work starts is the number on the invoice. There are no “findings” that change the price mid-job without your written approval.
- System isolation and negative-pressure setup. The technician connects a commercial-grade negative-pressure machine – typically a Rotobrush or Nikro unit, depending on the system configuration – to the main trunk line or plenum access. This creates a sustained vacuum across the full duct network, meaning loosened debris moves toward the collection unit rather than into the living space. All supply and return registers are sealed temporarily to maintain pressure through the system.
- Mechanical agitation of every duct run. Working from each register inward, the technician runs a rotary brush system through every supply and return line. The brush head breaks up compacted debris at elbows, transitions, and straight runs – the spots where particulate actually accumulates, as opposed to the register face where most budget cleaning stops. For Lewisville homes with flex duct, brush pressure is calibrated to avoid liner damage.
- Plenum and air handler cabinet cleaning. The plenum – the main distribution box that connects your air handler to every branch duct – is cleaned manually. So is the interior of the air handler cabinet, including the blower compartment and evaporator coil area (coil cleaning is a separate scope if needed, and you’ll see that in writing before it’s added). Debris inside the cabinet is extracted under negative pressure, not wiped into the drain pan.
- Register and grille cleaning. Every register is removed, wiped clean, and reinstalled. If a register cover is damaged, that’s noted in the job record and photographed – CleanRun doesn’t reinstall damaged components without flagging it.
- Post-job camera pass and photo record delivery. The technician runs the camera through the same duct runs photographed at step one. You receive a documented photo record – before and after, every run – as a standard deliverable. This is the record that supports the 365-Day Done Right Promise: if something wasn’t cleaned correctly, the photos show it, and CleanRun makes it right, in writing, not subject to manager discretion.
BeforeAfterFull System Cleaning Pricing in Lewisville
Full system cleaning in Lewisville is priced by the home’s duct count, square footage, and system configuration. The written price you receive before work starts accounts for all of these – there’s no separate line item added after the technician opens the first panel.
| Home Configuration | Typical Price Range | What’s Included |
|---|---|---|
| Single-story, up to 2,000 sq ft (10-14 vents) | $350 – $450 | All supply and return runs, plenum, air handler cabinet, all registers, before/after photo record |
| Single-story, 2,000 – 3,000 sq ft (15-20 vents) | $420 – $550 | Same as above |
| Two-story home, up to 3,500 sq ft (20-28 vents) | $500 – $650 | All runs across both floors, dual-unit systems quoted separately, photo record included |
| Dual-HVAC system (common in larger Lewisville homes) | $600 – $850 | Both plenums, both air handler cabinets, all runs on both systems |
What affects the price
- Vent count and duct layout. A home with 24 supply registers in a complex layout takes longer than a 12-vent open-plan house. Both get a written price before work starts.
- Flex duct vs. sheet metal. Flex duct systems, which are common in Lewisville homes built in the 1990s and 2000s, require a different brush calibration and take slightly longer to work through properly without damaging the liner.
- Debris volume and type. Heavy pet dander and fine construction dust require more passes. The camera inspection at step one tells us which category your system falls into, and the written price reflects that before work begins.
- Add-on services if warranted. Sanitizing, evaporator coil cleaning, and duct sealing are separate scopes with separate written prices. They’re offered when the camera shows a specific reason, not as an automatic upsell.

FAQs – Full System Cleaning
How long does a full system cleaning take in a Lewisville home?
Most full system cleanings in Lewisville take between three and four hours for a single-story home with 10 to 20 vents. Two-story homes with dual systems typically run four to five hours. That time includes the pre-job camera pass, mechanical cleaning of every run, air handler cabinet cleaning, and the post-job camera documentation. If the technician finds a specific condition – heavy debris at a trunk line transition, for example – that adds time, and you’ll hear about it before the schedule changes.
What’s the difference between a full system cleaning and a standard duct cleaning?
A full system cleaning covers every component air moves through: supply runs, return runs, the plenum, the air handler cabinet, and all registers. A standard duct cleaning, as many companies sell it, typically means running a vacuum near the register openings and skipping the plenum and air handler interior entirely. CleanRun’s process – documented with a camera before and after – shows the difference. The plenum and the first few feet of each trunk line are usually where the heaviest debris is found, and a cleaning that doesn’t reach those areas hasn’t done the job. Call (940) 240-8552 for a written price on a full system clean.
How often should Lewisville homeowners schedule a full system cleaning?
For most Lewisville homes, every three to five years is a reasonable interval under normal occupancy. Homes with pets, recent construction work, or occupants with respiratory conditions often benefit from a shorter interval – every two to three years. Lewisville’s long cooling season means HVAC systems here run more hours annually than systems in northern climates, which accelerates debris accumulation in duct runs, particularly at flex duct elbows and plenum transitions. The before photos from your last cleaning give you an objective baseline; CleanRun keeps the documented photo record so you can compare over time.
Does CleanRun move furniture or cut into walls to access duct runs?
No. Access is through the existing register openings, the main plenum access panel, and the air handler cabinet – all standard access points in any residential HVAC system. Furniture is moved by the technician as needed to reach floor registers and is returned to position before the job is complete. The technician photographs the access condition before working and after reinstallation. If a duct run cannot be reached through standard access – which occasionally happens with certain buried trunk configurations in older Lewisville construction – that’s flagged in the written scope and discussed before any work begins, not discovered as a surprise at the end of the job.
The Documentation That Backs This Up
CleanRun has operated under the H.A.V.E.N. Standard since day one. On a full system cleaning, that means three written documents leave with you when the truck does: the written price you approved before work started, the before-and-after photo record of every duct run, and the 365-Day Done Right Promise in writing. If the work is not right – based on the photos, not on a subjective argument – CleanRun makes it right. That’s written on the job record, not printed in a brochure that disappears into a drawer.
Tomas Reyes built CleanRun around the idea that an air duct cleaning company should be able to show its work. Every technician who walks into a Lewisville home is background-checked, uniformed, and identified by name before arrival – Haven Standard Clause 3. The equipment on the truck – Rotobrush and Nikro systems specifically – can be looked up independently by any homeowner who wants to verify what’s being used before agreeing to a price.
Since 2013, more than 52,000 homes have been cleaned under this process. Every one of them received a written price before work started and a photo record when the crew left. That’s not a marketing claim – it’s a documented operational standard that started on the first job and hasn’t changed.
