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.

We’re not affiliated with or authorized by Carrier. We’re an independent provider that has worked on enough Carrier residential and light-commercial equipment in North Texas to know where these units leak, sweat, and collect debris. From Performance-series air handlers in 1990s tract homes near Lake Lewisville to Infinity zoning systems in newer builds off I-35E, we’ve documented what actually fails and what Air Duct Cleaning services versus replacement looks like in this market.
Tomas Reyes, our owner, picked up his HVAC fundamentals at Manhattan’s Apex Technical School and has spent two-plus decades inside ductwork across North Texas. He built CleanRun around one habit: photographing what’s in the duct before and after, so the homeowner can see exactly what changed and for how much. That practice started with our first job in 2013 and hasn’t stopped. We’ve now served over 52,000 homes, every one with a written price before work started and a documented photo record when the crew left.
Why Trust CleanRun Air Duct Cleaning Lewisville for Your Carrier Air Duct Cleaning?
Carrier’s variable-speed and communicating systems reward technicians who understand how blower modulation, static pressure, and duct leakage interact. The Infinity FE4 air handler, for example, trims blower RPM to maintain airflow setpoints - a feature that masks return-side leaks and dirty coils until the compressor is working harder than it should. We’ve diagnosed enough of these in Lewisville to recognize the pattern: homeowner notices uneven cooling, thermostat shows normal operation, but supply static is low and amp draw is climbing.
Our crews carry Carrier-compatible OEM-style filter grilles, mastic, flex duct, and OEM blower wheels and coil cleaner matched to Carrier air handlers. We also stock quality aftermarket flex and fittings when they meet or exceed spec and save the homeowner money. Every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and we publish our license number on every page - not buried in a footer.
The equipment roster includes Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman. These are trade-recognized brands customers can look up independently. We name them because we want you to verify what we’re using before you agree to a price.
Here’s the before photo. Now let’s talk about what happens next.
Common Carrier Air Duct Cleaning Problems We Fix in Lewisville
- High static pressure and frozen suction lines on Performance/Infinity air handlers. Carrier’s FE4 and FV4 air handlers with variable-speed blowers pull high static through undersized or crushed flex runs. In Lewisville’s 1980s and 1990s tract homes - the dominant housing stock along I-35E - original builder-grade flex duct is now 30-40 years old, well past its 15-25 year functional lifespan. The blower compensates until it can’t, then you get high amp draw and frozen suction lines before you ever notice low airflow at the register.
- Lint and biofilm buildup on cased evaporator coils. The cased evaporator coils in Carrier Performance and Infinity air handlers trap lint and biofilm on the upstream face during DFW’s humid summers. This is worse when return ducting is undersized or the filter grille sits in a hallway ceiling, which is common in Lewisville’s slab-on-grade brick homes. The coil face packs solid, airflow drops, and the homeowner calls us thinking they need refrigerant.
- Mastic separation at metal plenum seams. Carrier’s older metal plenums and takeoffs were sealed with mastic that dries, cracks, and separates. Lewisville’s Blackland Prairie clay soils cause ongoing slab movement that stresses duct boot connections and plenum seams, accelerating this failure. The gaps pull attic debris - insulation fibers, rodent dander, construction dust - directly into the conditioned air stream. Attics here run 140-150°F in summer, so every cubic foot of leakage is hot, dirty air you paid to cool.
- Infinity zoning systems masking chronic duct problems. Infinity zoning with bypass dampers and communicating thermostats trims blower speed to compensate for duct issues. The system looks fine on the thermostat screen while return leaks and dirty coils go unnoticed. By the time the homeowner feels a problem, the compressor has been stressed for months. We see this in Lewisville’s larger two-story homes where zoning was sold as a comfort solution but the ductwork was never properly sealed.
- Lake Lewisville humidity driving mold in flex duct. The city’s direct adjacency to Lake Lewisville elevates ambient humidity in lakeside neighborhoods far more than in landlocked neighbors like Carrollton or Farmers Branch. In subdivisions built on former Corps of Engineers buffer land developed in the late 1980s - particularly near the eastern shoreline - we regularly pull flex duct sections with visible black mold on the inner liner and moisture-matted fiberglass. The same vintage home on the dry west side of I-35E rarely shows the same severity. This is genuinely distinctive to this part of Denton County.
BeforeAfterCarrier Parts & Our Repair-vs-Replace Approach
We stock Carrier-compatible OEM-style filter grilles, mastic, flex duct, and OEM blower wheels and coil cleaner matched to Carrier air handlers. When quality aftermarket flex and fittings meet or exceed spec, we’ll use them and pass the savings. Haven Standard Clause 1 requires a written price before any work starts - no exceptions - so you’ll see the parts breakdown and labor line-item before we touch a single panel.
If we find a cracked Carrier cased coil or a failing ECM blower module, we quote both repair and replacement honestly. No pressure, just numbers. The 365-Day Done Right Promise means if the work isn’t right, we make it right - backed in writing on every job, not stated only in marketing copy. For a free second opinion on any written estimate, bring a competitor’s quote and we’ll put our number next to it in writing. Call (940) 240-8552.
Our Carrier Service Process - Step by Step
- 1
Diagnosis with video inspection. We feed a camera through every accessible duct run and photograph the evaporator coil face, plenum seams, and flex connections. On Infinity systems, we also log blower RPM and supply static from the communicating thermostat before touching anything.
- 2
Written scope and price. Haven Standard Clause 1: you receive a written price before any work starts. The scope specifies what we’re cleaning, what we’re sealing, and what parts we’re replacing. No per-vent pricing, no open-ended labor rates.
- 3
Cleaning and repair. We perform evaporator coil cleaning, full system cleaning, and air leak repair as specified. Flex duct gets reattached with mastic, not tape. Metal seams get resealed. The coil gets pulled and cleaned if the camera shows blockage.
- 4
Testing and documentation. We verify airflow at key registers, check static pressure post-repair, and photograph every duct run before and after. The photo record is delivered as a standard job deliverable - not an extra, not upon request.
- 5
Warranty and follow-up. The 365-Day Done Right Promise goes into writing. If airflow drops or a seal fails within a year, we return and make it right.

FAQs - Carrier Air Duct Cleaning Service in Lewisville
No. We are an independent provider - not affiliated with or authorized by Carrier. We diagnose and clean Carrier systems based on hands-on field experience, not manufacturer certification. Our independence means no pressure to sell you a new Carrier unit when cleaning and sealing will solve the problem.
We stock Carrier-compatible OEM-style filter grilles, mastic, flex duct, and OEM blower wheels and coil cleaner matched to Carrier air handlers. We also use quality aftermarket flex and fittings when they meet or exceed spec and save the homeowner money. You see the parts breakdown in the written price before work starts.
A typical full-system cleaning and sealing on a Carrier Performance or Comfort series air handler in a Lewisville single-family home takes 3-5 hours. Infinity zoning systems add 1-2 hours for diagnostic logging and damper verification. We schedule by the job, not by the hour, so the crew stays until the photo record is complete and the static pressure checks out.
We service Performance Series (24ACC6/24ACC7 with FV4/FX4), Infinity Series (24ANB7/24ANB1 with FE4/FE5), Comfort Series (24ABC6 with FV4), and 38MURA/40MURA mini-split systems. If your model isn’t on this list, call (940) 240-8552 - we’ve likely worked on it.
Proper duct cleaning and coil maintenance performed by a qualified technician does not void Carrier’s warranty. We document our work with before-and-after photos and a written scope, which protects you if a warranty claim ever arises. We do not disassemble sealed refrigerant components or electrical control boards during routine duct cleaning.
Not necessarily, but it’s a symptom worth investigating. The Infinity FE4 and FE5 air handlers modulate blower speed to maintain airflow setpoints. If return ducting is leaking or the evaporator coil is dirty, the system runs at reduced RPM to hit its target. The communicating thermostat shows normal operation while the compressor works harder. We log actual static pressure and inspect the coil and ductwork to separate a real problem from normal modulation behavior.
In Lewisville’s climate - with North Texas attic temperatures exceeding 140°F in summer and Lake Lewisville’s elevated humidity in lakeside neighborhoods - we recommend evaporator coil inspection every 2-3 years and cleaning when the camera shows blockage. Homes with pets, recent renovation dust, or undersized return grilles may need more frequent attention. Call (940) 240-8552 to schedule a video inspection and we’ll show you what your coil actually looks like.
Yes, in most configurations. The 38MURA/40MURA systems have accessible branch ductwork and line sets that we can clean and inspect without disturbing wall-mounted units. We photograph the concealed components and deliver the same documented photo record as a full duct system.
Usually both, in Lewisville’s humidity. The cased coil in Carrier Performance and Infinity air handlers traps moisture and biofilm on the upstream face. If flex duct near Lake Lewisville has mold on the inner liner, the blower distributes that odor on startup. Our camera inspection identifies which component is primary. We clean the coil and affected duct sections, then seal to prevent recurrence. Call (940) 240-8552 for a free estimate - we’ll show you the photo evidence before quoting any work.
