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.
Guardsman HVAC Cleaning in Lewisville: What to Know First
CleanRun provides independent Guardsman HVAC cleaning in Lewisville, with most evaporator coil, blower, and condenser jobs completed in a single scheduled visit. We deliver a written price before any panel comes off, and every job ends with a documented photo record of what changed inside your system. Typical whole-system cleaning runs $340-$620 for Lewisville homes, depending on access and contamination level. If you own a Guardsman air handler or packaged unit and want to know what’s actually inside it before you agree to anything, call us at (940) 240-8552. We’ll put the number in writing, then show you the camera feed.
How Guardsman Products Fail - and How We Fix Them
- GMX Series evaporator coils: The aluminum fins on these coils trap construction dust and pollen at a higher rate than comparable copper-tube designs we’ve seen from Lennox and Carrier. In Lewisville, where spring oak pollen counts regularly exceed 3,000 grains per cubic meter, we’ve pulled coils from GMX units that looked like felted blankets. We use foaming cleaner with a low-pressure rinse, not a pressure washer, to avoid fin collapse. The photo record shows the fin density before and after.
- GMB Series blower wheels: The forward-curved blade design moves air efficiently but cakes with pet hair and sheetrock dust in newer Lewisville builds, especially in communities like Castle Hills where tight construction traps debris. The wheel goes out of balance, causing vibration and bearing wear. We remove the wheel, clean it in a contained solvent bath, and photograph the runout measurement before reassembly.
- GMC Series condensers: The louvered guard design protects the coil but creates pockets where cottonwood seed and grass clippings collect. We’ve found complete airflow blockage in Lewisville yards with mature trees. We disassemble the guard panels, use a soft-bristle rotary brush on the coil face, and document the pressure drop across the coil before and after cleaning.
- GMH Series heat exchangers: The clamshell design has more seams than tubular exchangers, and we’ve seen rust scaling at the weld points in Lewisville homes with high mineral content in their condensate. We scope the exchanger with a borescope, photograph any scaling or cracks, and if cleaning is viable, we use a non-acidic foaming agent that won’t etch the metal. If we find cracks, we stop and show you the image - that’s a replacement, not a cleaning.
- GMP Series air handlers with integrated UV: The factory UV mount location sits upstream of the coil, which is correct, but the bulb access panel is often blocked by flex duct in tight Lewisville attics. We’ve modified the access approach on dozens of these without disturbing the refrigerant lines. We photograph the bulb condition, note the manufacture date (they degrade whether lit or not), and replace only when the customer has the written price in hand.
Our Guardsman HVAC Cleaning Process

- 1
Written price delivered first. Haven Standard Clause 1: we inspect the accessible components, identify the contamination type, and put the full scope and price in writing before any work starts. No exceptions.
- 2
Diagnostic photography. We feed a borescope through the plenum - the main distribution box - and into the first duct run to document what the camera shows before a tool touches the system.
- 3
OEM vs. quality aftermarket decision. For Guardsman units, we stock direct-fit replacement UV bulbs and drain pans. For consumables like blower belts, we use Bando or equivalent spec-matched parts. We name the manufacturer on the written scope so you can verify it.
- 4
Contained cleaning execution. Evaporator coils get foaming cleaner with a controlled rinse into a sealed drain. Blowers come out for solvent bath cleaning. Condenser coils get rotary brush work with the power disconnected and locked out. Negative-pressure extraction (suction that pulls dislodged debris out of the system, not into your house) runs continuously during internal work.
- 5
Performance verification. We measure static pressure across the coil, check blower amp draw against the nameplate, and run the system through a complete heating or cooling cycle before we pack up.
- 6
Documented photo record delivered. Before-and-after images of every cleaned component, with timestamps, emailed or texted to you before the crew leaves. Here’s the before photo. Now let’s talk about what happens next.

AfterWhat Guardsman HVAC Cleaning Costs in Lewisville
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Evaporator coil cleaning (GMX/GMB series) | $280-$420 | Coil access (attic vs. closet), fin corrosion level, refrigerant line obstruction |
| Blower wheel & housing cleaning | $180-$290 | Wheel removal difficulty, bearing condition, housing liner degradation |
| Condenser coil cleaning (GMC series) | $160-$240 | Guard disassembly time, coil depth, surrounding vegetation density |
| Heat exchanger inspection & cleaning (GMH series) | $220-$380 | Borescope access, scaling severity, crack findings (stop-work scenario) |
| Whole-system cleaning (coil, blower, condenser) | $340-$620 | System age, prior maintenance history, Lewisville attic temperature conditions |
We do not quote per-vent or per-register prices. One flat price per system, agreed in writing, covers the full scope. Factors that raise the price: systems that haven’t been opened in 5+ years, attics over 120°F in summer (which is most Lewisville attics from June through September), and units with aftermarket modifications that block standard access. Call (940) 240-8552 for a free estimate - we’ll inspect and deliver a written number, no charge.
Why Lewisville Homeowners Call CleanRun Air Duct Cleaning Lewisville for Guardsman Work

We’ve been running jobs in Lewisville since 2013, including plenty of older homes near Castle Hills where the flex duct tends to sag and accumulate debris in ways that don’t show up until you put a camera inside. Tomas Reyes and our crew know the Guardsman product line from hands-on work, not from a distributor brochure. We’re also equipped for Lennox, Trane, and Carrier - so if your system is mixed-brand or you’re considering replacement options, we can compare across manufacturers without pushing one over another.
Every job carries the 365-Day Done Right Promise in writing: if the work is not right, we make it right. Haven Standard Clause 3: Verified Crews means background-checked, uniformed technicians who give you their names before they step inside. The documented photo record is not an upgrade. It’s the standard deliverable on every visit, included, because a technician who won’t show you what he found is a technician with something to hide.
FAQs
No. Manufacturer warranties cover defects in materials and workmanship; they do not require you to use a factory-authorized servicer for routine maintenance. As an independent Guardsman service provider, we document our cleaning methods and use manufacturer-specified or equivalent parts, so if a warranty claim arises later, you have a dated service record with photos. Keep your written scope and photo record with your warranty paperwork. Call (940) 240-8552 if you need a copy re-sent.
Replacement becomes the better option when the heat exchanger is cracked, the evaporator coil has fin corrosion exceeding 30% surface area, or repair parts are no longer stocked by the major distributors. We show you the borescope images and explain the threshold. Most Guardsman units we see in Lewisville are candidates for cleaning if they’re under 12 years old and have been maintained even intermittently. Call (940) 240-8552 and we’ll put an honest assessment in writing.
We stock OEM UV bulbs, drain pans, and control boards for current Guardsman series. For consumables like blower belts and contactors, we use spec-matched quality aftermarket - Bando, Honeywell, Aprilaire - and we name the manufacturer on your written scope so you can verify the specification. We do not use universal-fit parts that require modification to your unit.
A single-component cleaning - evaporator coil or blower - runs 90 minutes to 2 hours on site. A whole-system cleaning with coil, blower, and condenser typically takes 3 to 4 hours, including the diagnostic photography and performance verification. We schedule a specific arrival window, not a vague “morning or afternoon” block, and we call 30 minutes out.
The $79 coupon model typically covers a shop-vac at the register and a fog of deodorizer. It does not include opening the air handler, cleaning the evaporator coil, or photographing the inside of the ductwork. We’ve been called in after those jobs to find the plenum still full of debris. Our price covers the full scope, documented, with a written guarantee. If you have a competitor’s written estimate, bring it - Haven Standard Clause 2 is our Free Second Opinion, and we’ll put our number next to theirs at no charge.
