When You Need Full System Cleaning

Austin homes collect a specific mix of dust: cedar pollen from the Hill Country in winter, construction dust from all the new builds, and the fine gray grit that blows in during dry spells. If your HVAC system has been moving that air for years, the evidence is inside the ducts. Here are the signs that our Air Duct Cleaning services are the right call:

• Dust reappears on furniture within 48 hours of wiping it down. That dust is not sneaking through closed windows. It’s being blown out of your supply registers every time the system cycles on.
• You changed the filter and it looked clogged within two weeks. A filter that loads up that fast is catching debris that should never be in the airstream in the first place.
• You renovated or had major drywall work done. Drywall dust is fine enough to pass through a filter and settle deep in the duct system, where it keeps recirculating for months.
• You moved into a home where the previous owners had pets. Pet hair and dander work their way past the return grille and pack into the return ducts and the blower compartment.
• Someone in the home has allergies or asthma that improve when they’re away. If symptoms ease at work or on vacation, the indoor air is the likely trigger, and the duct system is part of that equation.
• Airflow is weak from several registers, even with a new filter. A clogged evaporator coil or a packed return duct will strangle airflow, and that makes your system work harder and run longer.

Our Full System Cleaning Process

We follow a defined sequence on every job. Our technicians are background-checked and uniformed, and they work to the Kingswell Way: say the price, show up in the window we gave, leave the place cleaner, put the guarantee in writing, and come back if it fails.

1. Inspect and document. We walk the system with you, check the registers, returns, coil, and blower, and confirm the scope and the written price before any work begins. No door-step revisions, ever.
2. Seal off the living space. We cover registers and returns and set up the Nikro negative-pressure unit. Negative-air extraction means the system is under vacuum the whole time, so loosened dust is pulled toward the vacuum, not pushed into your rooms.
3. Agitate the duct walls. The Rotobrush rotary brush system spins at the duct wall to dislodge the compacted layer of dust, hair, and debris that a vacuum alone will not move. Brush agitation loosens it; the negative air pulls it out.
4. Clean the air handler, blower, and evaporator coil. This is the part many duct cleaners skip. We open the air handler, clean the blower wheel and housing, and clear the evaporator coil so air moves the way the system was designed to move it.
5. Run HEPA-filtered air through the system. Our Abatement Technologies HEPA filtration captures particles down to 0.3 microns during the cleaning, keeping what we dislodge out of your breathing air.
6. Final walkthrough and written guarantee. We show you what came out, confirm the system is running right, and hand you the 365-Day Done Right Promise in writing. If anything falls short within a year, we return and make it right at no charge.

Full System Cleaning Pricing in Austin

Most Austin homes run between $450 and $900 for a full system cleaning. That range is honest and it holds: the written price is the final price, and you’ll have it before we start. Here’s how the cost typically breaks down:

• Single system, up to 10 vents: $450 to $550
• Single system, 11 to 16 vents, two returns: $550 to $700
• Larger home, two systems or 17+ vents: $700 to $900
• Heavy buildup, post-renovation cleanup, or pet-packed ducts: typically adds $100 to $200 to the base range

What moves the number: square footage, the number of supply and return registers, whether there are two air handlers, and how long the system has gone without a cleaning. A 1,400-square-foot home built in the 1990s with original ducts will usually land at the lower end. A 3,200-square-foot two-story with two systems and a Golden Retriever will run higher.

We do not quote over the phone and revise at the door. The estimate is free, and the number we give you is the number on the invoice. If the job turns out to need more than we quoted, we stop and call you before doing anything beyond the agreed scope. That’s the Kingswell Guarantee, and it’s been our standing practice since 2004.

Why Austin Dust Is Different

We’ve cleaned systems all over the Austin metro, and the buildup here has a character all its own. Cedar pollen season runs from December through February, and that pollen is fine enough to pass through a standard one-inch filter and coat the inside of your Return Duct Cleaning targets. Summer brings weeks of near-zero rain, and the dry ground turns to dust that gets pulled into the return air. Add in the construction boom, and many homes we visit carry a layer of drywall dust from the original build or a remodel that never got cleaned out of the system.

This matters because Austin HVAC systems run hard. Air conditioners here can log 2,000+ hours in a single year. The more hours the blower runs, the more air moves through whatever is sitting in those ducts. A partly clogged evaporator coil in a 100-degree August is not just an efficiency problem. It’s the difference between a system that holds 74 degrees and one that runs all afternoon without dropping below 79.

The Kingswell Guarantee and the 365-Day Done Right Promise

Kestrel Air Duct Austin is part of the Kingswell family of companies, and every job we do operates under the Kingswell Guarantee. It is not a slogan on a flyer. It is four commitments, documented in writing on every job:

• A written price before work begins. The number you approve is the number you pay.
• A defined arrival window. We show up when we said we would, and we call if anything changes.
• A clean job site. We leave your home the way we found it, and the Kingswell Way requires that the work area is cleaner when we leave than when we arrived.
• A written guarantee on the work. If the work falls short within 365 days, we return and make it right at no charge.

Here is what the 365-Day Done Right Promise covers in plain terms: if you find that the cleaning did not address the issue we agreed to solve, if debris we dislodged ends up back in your living space, or if the system underperforms in a way tied to the work we did, you call us. We come back. We fix it. No invoice, no debate, no fine print about “reasonable wear.” The promise is on the paperwork we hand you before we leave.

We also carry Honeywell and Aprilaire filtration products for homeowners who want to hold their indoor air quality steady between service visits. If we see a filtration upgrade that makes sense for your home during the cleaning, we’ll mention it once and leave it there. We’re an air duct company, not a sales team.

Equipment That Does the Job

You can clean ducts with a box-store shop vac and a drill brush. People do it. The problem is that a shop vac has no HEPA filtration and almost no negative pressure. It loosens debris and sends a good portion of it out the exhaust port and into the room. What we use is different in ways you can see and measure:

• Rotobrush rotary brush systems spin at the duct wall under power, breaking loose the compacted layer that a vacuum alone cannot move. The brush does the dislodging; the vacuum does the capture. That combination is what makes the difference between a surface dusting and an actual cleaning.
• Nikro negative-pressure units pull air through the entire duct run while we work, so every particle we loosen is carried out of the house through the vacuum system, not redistributed through the registers.
• Abatement Technologies HEPA filtration traps particles down to 0.3 microns. That’s fine enough to capture mold spores, pollen, and the fine dust that passes through normal filters like it’s not even there.

These are contractor-grade tools, maintained and used by technicians who clean air systems every day. A full system cleaning is not a job we rush, and it’s not one we hand to a trainee with a checklist and a flashlight.

Full System Cleaning vs. a Basic Vent Cleaning

There’s a difference between a $99 vent cleaning and a full system cleaning, and it’s worth understanding before you book anything. A basic vent cleaning addresses the visible part: the register covers, the first few feet of Supply Duct Cleaning area at each opening, and maybe the return grille. It leaves the air handler, blower wheel, evaporator coil, and the deep runs of ducting untouched.

A full system cleaning, by contrast, treats the entire airstream. That means everything from the return grilles through the return ducts, into the air handler, across the blower and coil, and back out through the supply trunk and branch ducts. If the coil is packed with dust, cleaning only the ducts is like replacing the filter on a car with a clogged radiator. The symptom gets treated for a week and comes right back.

We recommend a Residential Duct Cleaning touch-up in one scenario: a newer home, no pets, no renovation, and a system under ten years old where the homeowner just wants basic maintenance. For everything else, full system cleaning is the honest fix, and it’s what we quote most often in Austin.

How Long Does Full System Cleaning Take?

Plan on 4 to 6 hours for a typical Austin home with a single system and 10 to 16 vents. A two-story with two air handlers can take up to 8 hours, which is why we schedule those as a full-day visit rather than trying to wedge them into an afternoon.

During that time, your system will be off, and you’ll hear the equipment running. You can stay in the home. Most homeowners do. Some work from the back room while we clean, and that’s fine; the HEPA filtration keeps the air in the living space cleaner than it was before we started. What we ask is that the system stays off until the job is complete, and that we have access to the air handler, the registers, and the thermostat.

What We Clean, In Plain Terms

Here is the full list, so you know exactly what a full system cleaning includes and can compare it against any other quote:

• Supply ducts: the runs that carry conditioned air from the air handler to each room.
• Return ducts: the runs that pull room air back to the system, typically the dirtiest part of the job.
• Air handler and blower compartment: where the blower wheel lives, and where dust and hair collect on the motor housing.
• Evaporator coil: the cold coil that pulls humidity from the air. A dirty coil reduces cooling capacity and raises your electric bill.
• Plenum boxes: the sheet-metal boxes at the top and bottom of the air handler where ducts connect.
• Registers and grilles: cleaned, wiped, and reinstalled.

After the Cleaning: What Changes

Most customers notice three things within the first week. The air smells different: less stale, less like the inside of a hot attic. The dust settles slower: surfaces stay clean longer because the system is no longer blowing fine particles into the rooms. And the airflow improves: rooms that used to lag in summer hold temperature better because the coil and blower are not fighting a layer of packed debris.

If you want to maintain that difference, we’ll point you toward the right filtration for your setup. An Aprilaire media filter does far more than a standard one-inch fiberglass filter, and a Honeywell whole-home filter can help during cedar season. These are options we offer, not requirements, and the decision stays entirely with you.

FAQs – Full System Cleaning

How much does full system cleaning cost in Austin?

Full system cleaning in Austin costs between $450 and $900 for most homes. The price depends on square footage, number of vents and returns, whether there are two air handlers, and how much buildup is in the system. Every Kestrel job includes a written price before work starts, and estimates are free. Call (254) 848-6913 for an exact quote on your home.

How long does a full system cleaning take?

A full system cleaning takes 4 to 6 hours for a typical single-system Austin home, and up to 8 hours for a two-story with two air handlers. We schedule accordingly and arrive in the window we gave you. The 365-Day Done Right Promise covers the work for a full year after the job, in writing.

Is full system cleaning worth the cost compared to a basic vent cleaning?

If your air handler, blower, and evaporator coil have never been cleaned, a basic vent cleaning will not solve the problem, because the debris in those components keeps blowing back into the ducts. A full system cleaning addresses the entire airstream. For most Austin homes over ten years old, it is the fix that lasts. We’ll inspect with you and show you what’s actually in the system before you decide.

Will full system cleaning help with allergies?

Many Austin homeowners report fewer indoor allergy symptoms after a full system cleaning, especially during cedar season when pollen coats the inside of return ducts. While no cleaning can eliminate allergens entirely, removing the accumulated pollen, dust, and pet dander from the airstream reduces what circulates through your home. If allergies are the main concern, ask us about Aprilaire filtration when we’re on-site.

Do you provide a written guarantee on full system cleaning?

Yes. Every full system cleaning includes the 365-Day Done Right Promise in writing. If the work falls short within a year for any reason tied to the job, we return and make it right at no charge. It’s part of the Kingswell Guarantee that has governed every Kestrel job since 2004.
