Supply Duct Cleaning in Dallas, TX

Supply Duct Cleaning in Dallas, TX

Supply duct cleaning in Dallas typically costs between $290 and $490 for a standard home, depending on the number of vents and how much buildup has settled in the system. For a detailed breakdown, see our guide on How Much Does Air Duct Cleaning Cost in Dallas, TX? (2026 Price Guide). That price includes the full run of supply lines, from the plenum at the air handler all the way to the register grilles in each room. If your supply ducts have never been cleaned and your home is more than ten years old, you’re likely past due.

Here’s the plain version: your supply ducts are the channels that carry conditioned air to the rooms in your house. The return ducts pull air back to the unit. We clean both, but the supply side is where most of what you breathe actually travels. At Hollis Air Duct Dallas, we run professional-grade negative-air machines and rotary brush systems through every supply line, not just the trunk. We’re part of the Garrison Partners family, and we’ve been doing this work since 2004. When you call (361) 309-6223, you get a live person, not a voicemail queue.

When You Need Supply Duct Cleaning

Most Dallas homeowners call us because they’ve noticed something specific, not because they woke up wanting their ducts cleaned. Here’s what typically pushes people to pick up the phone:

• Visible dust on register grilles and nearby walls. If you wipe a vent and it’s coated again within a week, that dust is being pushed through the supply lines every time the blower runs. In older Dallas homes near White Rock Lake or East Dallas, decades of fine dust can pack into supply runs even when the trunk looks okay.
• Rooms that stay warmer than others regardless of the thermostat. Supply runs that are partially blocked with debris deliver less air to the far rooms. If your north-facing bedroom never cools in August, the problem is often in the supply branch feeding that room, not the AC unit itself.
• You found drywall dust or remodeling debris. After a kitchen remodel or any drywall work, fine gypsum dust gets pulled into the return and pushed out through the supply side. If you’ve renovated in the last year and never cleaned the ducts, that dust is still circulating.
• Allergy symptoms flare up at home but not at work or outside. Supply ducts can hold pollen, pet dander, and mold spores. When the blower kicks on, those particles are delivered directly into the rooms where you sleep and eat.
• You just bought the house and don’t know its history. Sellers rarely clean ducts. In neighborhoods like Lakewood, Preston Hollow, and North Dallas, we regularly pull years of accumulated hair, dust, and construction debris out of supply lines in homes that look spotless on the surface.
• You can hear rattling or feel weak airflow at specific registers. Loose debris in a supply run will rattle when the blower pushes air past it. Weak airflow often means a partial blockage somewhere between the plenum and the register.

If any of these sound familiar, call (361) 309-6223. We’ll tell you honestly whether supply duct cleaning will address the problem, or whether you’re better served by a different fix.

Our Supply Duct Cleaning Process

We don’t show up with a shop vac and a hope. Every supply duct cleaning at Hollis Air Duct Dallas follows the same steps, in the same order, every time, starting with a Video Inspection so you see the condition before we begin. That consistency is what The Garrison Standard is built on.

1. Walkthrough and written quote. Our technician counts your supply registers, checks the trunk line, and gives you a written price before any work starts. That number does not change at the door. You approve it before we unload equipment.
2. Protection and access. We lay down floor protection and open access at the plenum or a supply trunk point. Furniture stays in place; we work around it. Our technicians are background-checked and uniformed, so you know exactly who is in your home.
3. Negative-air setup. We connect a Nikro negative-air machine to create vacuum pressure in the supply system. All the air and debris we dislodge gets pulled to the collection unit, not blown into your living room.
4. Rotary brush agitation. A Rotobrush rotary brush system runs through each supply branch and the trunk line, scrubbing the walls loose from accumulated dust, dust bunnies, and debris. The brush does the work; the negative air does the capture.
5. Register and grille cleaning. Each supply register cover gets cleaned before it goes back on. You’d be surprised how much buildup sits on the backside of a grille, and there’s no point cleaning the pipe if the register is going to shed dust back into the airflow.
6. Final inspection and walkthrough. We check airflow at each supply register with the blower running, then walk you through what came out of the system. You see the collection canister, not a vague “looks good” from the tech.

This is not a twenty-minute blow-and-go. A proper supply duct cleaning in a typical Dallas home takes two to four hours, depending on the number of supply runs and their condition.

Supply Duct Cleaning Pricing in Dallas

Here’s what you should expect to pay for supply duct cleaning in Dallas, based on the homes we service regularly:

Home Size	Supply Runs	Typical Range
Small condo or townhome	4 – 6	$290 – $350
Typical 3-bedroom home	7 – 10	$350 – $430
Larger 4 – 5 bedroom home	11 – 15	$430 – $490
Two-system homes	16+	$490+

What pushes a job toward the top of the range? Long supply runs in a ranch-style home, heavy buildup, flex duct that needs extra care, or register access behind furniture. What pulls it down? A simple floor plan, recent construction, or ducts that were cleaned within the last few years.

The key point: your quote is written before work starts, and it does not move. There’s no “we found extra issues once we opened it up” upcharge. That’s part of The Garrison Code, and it’s been part of how we operate since Roy Castellanos started running the Dallas location.

We also offer Air Duct Cleaning in Dallas that includes both supply and return sides, plus options for dryer vent cleaning and duct sealing. If you’re weighing supply-only cleaning against a full system job, we’ll walk you through both prices and let you decide. No pressure, no bundling games.

Estimates are free. Call (361) 309-6223 and we’ll get you a number you can trust.

Why Supply Ducts Matter More Than You Think

Every cubic foot of air your HVAC system heats or cools travels through the supply side before it reaches you. That’s not a marketing line; it’s the mechanics of a forced-air system. The blower pushes conditioned air through the supply plenum, into the trunk, through branch lines, and out the registers. If those pathways are dirty, the “conditioned” air picks up whatever is in the pipe.

In Dallas, we have specific conditions that make supply ducts dirty faster than in other regions. Our climate runs the AC hard from May through September. That’s five months of continuous blower operation pulling air through the system. Add in the fine clay dust that’s native to North Texas soil, and you get a fine particulate that settles in ducts and re-enters the air stream every cycle. Homes in areas like Mesquite, Garland, and Richardson sit on the same clay-heavy soil, and homeowners in those areas report the same pattern: dust returns to surfaces days after cleaning.

Hollis Air Duct Dallas uses professional filtration when the job calls for it. On jobs where there’s mild particulate or allergen concern, our techs can discuss filtration products from Honeywell and Aprilaire, and we use Abatement Technologies equipment when negative air collection demands that level of filtration. We don’t sell anything as an add-on without explaining, in plain English, what it does and what it costs.

How Supply Duct Cleaning Fits Into a Bigger Air Quality Plan

Supply duct cleaning is one leg of a four-leg stool. Most of our Dallas customers see the best results when they address all four:

• Supply and return duct cleaning. Both sides of the system carry the air. Cleaning only the supply side leaves the return side recirculating whatever’s settled there. Some homeowners start with supply only and schedule returns later; we’re fine with that.
• Dryer vent cleaning. A clogged dryer vent is a fire hazard and a lung irritant. Our Air Duct Cleaning in Dallas page covers how we handle the full system, and dryer vent work is a natural companion service.
• Duct sealing. Leaky ducts in a Dallas attic waste conditioned air before it ever reaches the rooms you paid to cool. If we find leaks during a supply duct cleaning, we’ll point them out and give you a written quote for sealing. No obligation.
• Regular filter changes. We recommend checking your HVAC filter monthly during peak cooling season in Dallas. A dirty filter sends more particulate into the system, which means faster buildup in your supply lines after we’ve cleaned them.

The 365-Day Done Right Promise covers our supply duct cleaning work for a full year. If something isn’t done right, we come back and make it right at no charge. That includes a free second visit. It’s written on every job, not negotiated after the fact. Roy Castellanos has kept that promise in place at Hollis Air Duct Dallas because it’s simply how a disciplined trade company should operate.

What You Should Ask Any Duct Cleaning Company in Dallas

Before you call anyone, including us, you should know what separates a real duct cleaning from a $49 special that turns into a $700 upsell. Here are three questions that will instantly tell you what kind of company you’re dealing with:

• “What method do you use, and will you show me the collection canister?” If the answer is a shop vac and a brush on a drill, keep looking. Ask to see the negative-air machine and the rotary brush system. Hollis Air Duct Dallas uses Rotobrush rotary brush systems and Nikro negative-air machines, and yes, we’ll show you what we collected before we leave.
• “Is the price in writing before you start, and does it change if you find heavy buildup?” If they can’t answer “yes” and “no” in that order, move on. Our price is written, it’s fixed, and it covers the work even if the buildup is worse than the estimate assumed.
• “What happens if I’m not satisfied with the cleaning?” Listen for a specific, in-writing answer. Ours is the 365-Day Done Right Promise: if the work fails within a year, we return and fix it at no charge, including a free second visit.

These questions protect you from the exact scenario our customers have told us about: a low teaser price, a tech who shows up and doubles the quote at the door, and a crew that leaves dust on the furniture and never answers the phone again. We’re built to be the opposite of that.

FAQs – Supply Duct Cleaning

How long does supply duct cleaning take?

Supply duct cleaning in Dallas typically takes two to four hours for a standard single-family home, depending on the number of supply runs and how much buildup has accumulated. Homes with multiple systems or extensive flex duct can take longer. We’ll give you a time window when you book, and we arrive inside it under The Garrison Code.

Is supply duct cleaning worth the money?

Supply duct cleaning is worth the money if you have visible dust at registers, remodeling debris in the system, unexplained allergy symptoms at home, or airflow that’s weaker in certain rooms. If your ducts are less than five years old and you’ve maintained good filtration, you may not need it yet. Call (361) 309-6223 for an honest assessment; we’ll tell you if we think you can hold off.

What’s the difference between supply duct cleaning and full air duct cleaning?

Supply duct cleaning addresses only the lines that carry conditioned air from the air handler to your rooms. Full air duct cleaning includes the supply side, the return side, and the air handler plenum. The return side gets dirty too, since it pulls air from the house back to the unit. If you want both, our Air Duct Cleaning in Dallas page explains the complete service.

Can you clean supply ducts the same day I call?

Yes, we offer same-day supply duct cleaning when the schedule allows, and our phones are answered by a live person 24/7. Call (361) 309-6223 and we’ll tell you straight whether we can get a technician to your home today or if the next open window is tomorrow.

Do I need to leave the house during supply duct cleaning?

No, you don’t need to leave. The negative-air setup keeps dislodged dust inside the collection system, not in your living space. You can stay in the house and go about your day while we work. Most homeowners check in at the end to see what came out of the ducts.

Will supply duct cleaning reduce my energy bill?

Supply duct cleaning can improve airflow, which means your system runs more efficiently and may cycle less often during Dallas summers. The biggest energy gains come from duct sealing if we find leaks during the cleaning, not from the cleaning itself. We’ll note any leaks we find and give you a separate written price for sealing.

How often should I have supply ducts cleaned in Dallas?

In North Texas, we recommend having supply ducts cleaned every three to five years, more often if you have pets that shed heavily, you’ve done remodeling, or someone in the home has significant allergies. The Dallas climate runs HVAC systems hard, and fine clay dust settles quickly. If it’s been five years or more since your last cleaning, it’s time to call (361) 309-6223.
