Guardsman Air Duct Cleaning in Texas: What to Know First
As an independent Guardsman service provider, Bellows Air Duct & Vent Co. of Texas cleans Guardsman residential and commercial duct systems across the state, with most jobs completed in a single visit and upfront pricing disclosed before we lift a single tool. We’re square dealers - the price on the phone is the price on the invoice, backed by our 90-Day Done Right Promise in writing. If you own a Guardsman air handler, supply plenum, or flex-duct assembly and need it cleaned, inspected, or restored to proper airflow, call us at (866) 347-2063. We’ve been at this since 1984, and we don’t leave a job site until the airflow numbers make sense.
How Guardsman Products Fail - and How We Fix Them
- Guardsman G-Series residential air handlers (G100-G400) develop blower wheel imbalance after years of Texas dust accumulation, especially in homes north of Dallas where caliche soil creates fine particulate that cakes onto aluminum blades. We remove the wheel assembly, clean it off-site with a non-caustic solution safe for Guardsman’s factory coating, then rebalance before reinstalling. A dirty wheel strains the motor and throws your airflow numbers off by 15-20%.
- Guardsman FlexGuard flexible duct (FG-6 through FG-14) sags at the mid-span support points in attics across Central Texas, where summer attic temperatures exceed 140°F and degrade the wire helix. The sag creates a lint and dust trap that standard vacuum heads miss. We run a camera first to map the sag locations, then use a Rotobrush system with a reverse-bristle head that pulls debris uphill against gravity.
- Guardsman Snap-Seal return plenums (SSR-24, SSR-36) lose their gasket compression at the snap joints after 10-15 years of thermal cycling, which is accelerated in Texas by the gap between 100°F attic summers and 30°F winter nights. We disassemble, clean the joint faces, and reseal with mastic rated for Guardsman’s operating temperatures - never duct tape, which fails in six months here.
- Guardsman Commercial Series CS-800 and CS-1200 mixing boxes jam at the damper pivots in Houston-area jobs where Gulf Coast humidity swells the felt seals. The damper hangs open or shut, throwing zone balance. We clean the pivot pins with a dry lubricant compatible with Guardsman’s OEM spec, replace swollen seals with a silicone-impregnated aftermarket part that handles humidity better than factory felt, and cycle-test every position before we leave.
- Guardsman Guardian UV air purifier add-ons (GUV-150, GUV-300) suffer from fouled quartz sleeves that owners don’t know exist - the UV lamp looks fine, but the sleeve is coated with biofilm that blocks the 254nm wavelength. We pull and hand-clean each sleeve with a citric acid solution, check the lamp output with a radiometer, and only recommend replacement if output has dropped below 70% of spec. Most Texas techs skip the sleeve entirely and sell you a lamp you don’t need yet.
Our Guardsman Air Duct Cleaning Process
- 1
Call and schedule. A live person answers, 24 hours a day. We ask about your Guardsman model if you know it, the age of the system, and what you’re noticing - noise, smell, weak airflow, or higher bills.
- 2
Arrival and camera inspection. Our tech walks the system with a borescope before touching anything. You see what we see on the monitor. For Guardsman FlexGuard runs, we note sag points and joint conditions.
- 3
Upfront pricing. We show you the exact cost based on what the camera revealed. No bait coupons, no price changes at the door. The number we say is the number on the invoice.
- 4
Clean and repair. We select the right brush head for your Guardsman duct type - aggressive poly for metal, softer nylon for FlexGuard - and run negative air from a Nikro HEPA collector. Parts decisions are explained: OEM Guardsman when warranty matters, quality aftermarket when it performs better in Texas conditions.
- 5
Post-clean verification. Camera goes back in. You see the after. We measure static pressure and airflow at the registers. The numbers have to make sense before we pack up.
- 6
Written guarantee. You get our 90-Day Done Right Promise on the spot. If something’s not right, we return at no charge. No paperwork, no arguing.

Why Texas Homeowners Call Bellows Air Duct & Vent Co. of Texas for Guardsman Work
We’ve cleaned Guardsman systems in Texas since the brand first showed up in suburban Dallas tract homes in the early 1990s. Wade Kellerman, our owner, learned the trade in this market - he knows what caliche dust does to a G-Series blower, what Houston humidity does to a CS-800 damper, and when an aftermarket seal outperforms OEM. Our techs are background-checked, uniformed, and trained on Guardsman specifics, not just generic ductwork. We also service Lennox, Trane, and Carrier, so if your system is mixed-brand, we don’t guess. Calls are answered by a live person 24 hours a day. Most jobs finish in one visit. We stand behind it - and around here, that has meant something for a long time.
FAQs
No. Proper cleaning by a qualified technician does not void your Guardsman warranty, provided we don’t alter factory components or use unapproved chemicals. We document our methods and materials on every invoice in case you need to file a claim. If your system is still under warranty, we use OEM-compatible procedures and note serial numbers. Call (866) 347-2063 and we’ll verify your coverage before we schedule.
We stock common Guardsman wear items - gaskets, seals, UV sleeves - and source OEM parts through our distributor network when the job calls for it. For Texas-specific issues like humidity-swollen CS-Series damper seals, we sometimes recommend a quality aftermarket alternative that outlasts factory felt in Gulf Coast conditions. We explain the trade-off and let you decide before we order anything.
Cleaning is almost always the better value if the duct is structurally sound. FlexGuard with minor sag and surface soiling cleans up well. We recommend replacement only when the wire helix is corroded through, the inner liner is torn, or repeated cleaning hasn’t restored airflow. We’ll show you the camera footage and run the numbers both ways - no pressure either direction. Free estimates: (866) 347-2063.
Most Guardsman cleanings in the Dallas-Fort Worth, Houston, Austin, and San Antonio areas schedule within 48 hours. Emergency service for total airflow loss or post-construction contamination is available same day in most cases. We answer calls 24 hours a day, and we’ll give you a firm arrival window, not a four-hour guess.
We keep a permanent 5% Senior and Veteran discount, and we run a standing $89 Seasonal Tune-Up special that includes a basic duct inspection. For Guardsman systems needing repair work over $250, we offer $50 off. We also provide free second opinions on any written estimate you’ve received from another company - bring it in and we’ll tell you straight if it’s fair.
