Guardsman Air Duct Cleaning in Houston: What to Know First
Guardsman air duct cleaning in Houston typically runs $450 – $900 for a full residential system, and most jobs are completed in a single visit lasting four to six hours. We’re an independent Guardsman service provider, not a manufacturer-authorized shop, and we quote one flat price per system before any work begins. If you own a Guardsman system in Houston and your registers are blowing dust, your rooms smell stale, or you simply can’t remember the last time the ducts were cleaned, this page will explain exactly what we do, what it costs, and how we protect your home while we work. Call (940) 314-5008 and you’ll get a person, not a recording.

How Guardsman Products Fail – and How We Fix Them
Guardsman ductwork shows up in a lot of Houston homes, particularly in houses built during the 1990s and early 2000s. We know its failure patterns because we’ve cleaned enough of it to recognize what repeats, what’s normal aging, and what needs attention beyond a cleaning.
- Guardsman flexible duct with collapsed inner liner. In Houston attics, flex duct gets baked. The inner plastic liner on Guardsman flex can separate from the insulation and collapse inward, restricting airflow to a trickle. During cleaning, our negative-air setup pulls the liner back open so we can see the damage. If it’s too far gone, we tell you honestly and quote a replacement before we do anything else.
- Guardsman rigid ducts with register boots sealed by painted-over caulk. In older Heights homes, we see registers that have been painted over so many times the boot is effectively glued shut. We carefully score the caulk, remove the register, and clean the boot by hand before running the Rotobrush through. If we skip that step, you get a clean duct and a register that still doesn’t sit right.
- Guardsman supply plenums with loose fiberglass insulation. Houston humidity breaks down the adhesive that holds interior plenum insulation in place. On Guardsman systems from the early 2000s, we often find fiberglass shedding into the airstream. Our cleaning protocol uses HEPA-filtered negative air to capture loose fibers, and we photograph the plenum so you can see the before and after.
- Guardsman return ducts that pull attic air through unsealed joints. Older Guardsman returns in Houston lose sealant faster than supply runs because they’re under constant negative pressure. What looks like a dirty return is often attic dust being pulled through gaps. We clean the duct, then point out where the sealant has failed. A return that keeps pulling attic air will get dirty again fast, and we’d rather tell you that than sell you a cleaning that won’t last.
- Guardsman flex runs kinked by careless prior work. We regularly find kinks where Guardsman flex was pulled too tight around joists or trusses. A kinked run holds dust and restricts flow. During cleaning, we straighten what’s safe to straighten and flag what needs rerouting. We don’t yank on ductwork that’s been in place for twenty years, because that’s how you create a new problem while fixing an old one.
Our Guardsman Air Duct Cleaning Process
Here’s what a typical Guardsman job looks like from the first call to the final walkthrough:
- 1
You call (940) 314-5008, and Paul or a team member answers. You tell us about your home, the age of the system, and anything you’ve noticed: dust, smells, weak airflow. We schedule a time that works around nap hours and the kids’ school schedule when we can.
- 2
We inspect before we clean. The crew arrives in uniform with shoe covers on before the front door closes behind them. We check the returns, open a representative sample of registers, and look at the air handler. You get a written flat price for the whole job, one system, one number, before a single panel comes off.
- 3
We protect your floors and furniture. Drop cloths go down under every register we open. We move what needs moving with your permission, and we don’t touch pet areas unless you tell us to. Our equipment runs quieter than rental units, so a sleeping baby in the next room usually stays asleep.
- 4
We clean the full system. Negative air setup on the main trunk, then supply lines and returns cleaned branch by branch with Rotobrush and Nikro equipment. Every vent gets attention. We don’t rush the last register because the clock says it’s time to go.
- 5
We show you the proof. After cleaning, we photograph the inside of the plenum and key duct runs so you can see the result. Before we leave, we go over anything we noticed: a loose boot, a torn flex run, a filter that should be changed sooner than the one in there now.
- 6
You get the 365-Day Done Right Promise. If something isn’t right, we come back and make it right. That’s the Cedarwell Care Promise, and it’s not a marketing line. It’s how we’ve operated since 2005.

AfterWhat Guardsman Air Duct Cleaning Costs in Houston
For a typical single-family home in Houston with one HVAC system and 10 – 20 vents, our Guardsman air duct cleaning runs between $450 and $900. Here’s a breakdown of what drives the price:
- Full system cleaning (supplies, returns, trunk, air handler): $500 – $800 for a standard 1,500 – 2,500 sq ft Houston home.
- Smaller homes or single systems with 8 – 10 vents: $450 – $550.
- Larger homes, two systems, or extensive flex duct replacement: $800 – $1,200 depending on access and condition.
- Add-on dryer vent cleaning: $75 – $125, and we’ll tell you if it’s needed rather than tacking it on by default.
What changes the price: the number of systems, how accessible the ductwork is, the condition of the registers, and whether any repairs are truly necessary. We give you one written price for the cleaning itself. If we find a repair that should happen, we quote it separately and you decide before anything is done. Estimate calls are free, and we’d rather talk to you for ten minutes than have you surprised by an invoice.
Why Houston Homeowners Call Mortons Air Duct Houston for Guardsman Work
We know Guardsman ductwork because we’ve cleaned hundreds of systems in Houston, from Heights bungalows with twenty-year-old rigid duct to newer Fort Bend homes with flex throughout. We also work on Lennox, Trane, and Carrier systems, which means when we find a crossover issue, like a variable-speed blower that’s been running against a clogged return, we understand the whole picture. Paul Adeyemi, our owner, learned this trade at Los Angeles Trade-Technical College and has spent the better part of two decades cleaning and inspecting duct systems across Houston. He quotes a flat price before any work begins, and he doesn’t move to the next vent until the previous one is done right. Our techs are background-checked, uniformed, and work to the Cedarwell C.A.R.E. values. Shoe covers and drop cloths are not optional. A photo of the cleanup before we leave is not a favor. It’s the job. And if it’s not done right, the 365-Day Done Right Promise means we make it right.
Frequently Asked Questions
No, air duct cleaning does not void a Guardsman warranty. We use negative-air equipment and follow cleaning methods that are safe for flex duct and rigid duct alike. We never use high-pressure air alone, which can damage flex liners, and we inspect every run before we clean it. If a duct is already compromised, we’ll tell you and let you decide how to proceed before we touch it.
In Houston’s climate, every 2 – 4 years is reasonable for most homes. Between the humidity, the oak pollen in spring, and the dust that blows in whenever the AC runs for nine months straight, Guardsman systems in our area collect more debris than systems in drier climates. Homes with multiple pets or recent construction nearby trend closer to every 2 years. Homes with good filtration and no pets can often go three or four.
Most very low quotes are for a partial clean: just the supplies, or just a quick vacuum of the main trunk, or a per-vent price that sounds small but multiplies fast. Some companies advertise a low number and then “discover” mold or extra fees once they’re in the house. We give one flat price per system before we start, and that’s the price. No per-vent math, no surprise charges. Call (940) 314-5008 and we’ll explain what you’re getting for the number we quote.
We photograph the inside of your plenum and representative duct runs after cleaning, and we show you those photos before we leave. You’ll see the difference, not just take our word for it. If you want, we’ll walk the house with you and show you the registers we cleaned. That’s part of the Cedarwell Care Promise, and it’s been our standard since 2005.
Yes. Guardsman flex duct needs a gentler approach than rigid duct, and our Rotobrush and Nikro equipment is designed for exactly that. We don’t shove stiff tools into flex runs, and we control the negative-air pressure so the liner isn’t stressed. If we find a flex run that’s already torn or collapsed from age or heat, we stop and tell you what we found and what replacement would cost. As Paul puts it: “I’ll tell you what I see, what it’ll take, and what it’ll cost – before I touch a thing.”
