How Much Does Duct Cleaning Cost in Austin?

Duct cleaning in Austin typically runs $350 – $550 for a standard single-system home, with most homeowners paying around $425 for a full clean of all supply and return ducts, including the main trunk lines. Larger homes with two systems or extensive ductwork can push the total to $700 – $900. At Brandt HVAC Co Austin, we give you a written price before any work starts, so you’ll know your exact cost before we touch a single vent.

Duct Cleaning Cost Breakdown (2026)

Here’s what you’re paying for, line by line, based on the Austin market this year.

What Moves Austin Duct Cleaning Prices Up or Down

A few things push costs toward the top or bottom of those ranges. Homes with ductwork in the attic, which is common across Austin’s older central neighborhoods, need more labor because the technician has to work in a hot, tight space. If your home has flex duct from the 1980s that’s sagging or kinked, the cleaning takes longer. And homes with pets, especially long-haired dogs, often need an extra pass because the hair mats against the inside walls of the duct.

What Affects Duct Cleaning Pricing in Austin

• Number of systems. A single-story home in Crestview or Allandale with one air handler costs less than a two-story home in Circle C or Steiner Ranch with separate upstairs and downstairs systems.
• Age and condition of ductwork. Austin homes built before 1990 often have metal ducts with failing tape at the joints, which take more care to clean without damaging. We see this constantly in Hyde Park and Bouldin Creek.
• Local pollen and dust load. Cedar fever season blankets Austin from December through February. If your ducts have never been cleaned, the fine cedar dust accumulates in the return side first, and it compacts, which requires more agitation to loosen.
• Pets and occupancy. More occupants and more pets mean more skin cells, hair, and tracked-in dust. A home with three large dogs in Mueller is going to need a deeper clean than a two-person household in East Austin.
• Mold or moisture issues. Austin’s humidity, especially in May and September, can create condensation inside ducts. If a technician finds visible mold growth, sanitizing adds $75 – $175 and is worth doing right then.
• Access constraints. Attic-mounted air handlers with low-clearance ductwork in ranch-style homes from the 1970s take longer, and labor is the biggest line item in any duct cleaning quote.

How to Save on Duct Cleaning

The simplest way to keep costs down is to combine duct cleaning with a home HVAC tune-up visit, since we’re already on site and can often bundle the inspection. Change your return filters every 30 – 60 days during Austin’s high-pollen months, which reduces the debris load and makes future cleanings faster. If your ducts were cleaned in the last three to five years and you’ve kept up with filter changes, you may not need a full clean yet. A quick camera look can tell you for sure.

We also give free, no-pressure estimates by phone. A real person answers when you call (361) 326-1553, and we’ll tell you over the phone what a typical clean costs for a home your size before we ever book a visit.

Is Duct Cleaning Worth It in Austin?

This is the question behind the pricing question. Here’s our straight answer: if your home has any of the following, duct cleaning is a practical spend, not a luxury.

• Visible dust puffing from registers when the system kicks on
• A family member with asthma or allergy symptoms that worsen at home
• Pet hair or dander buildup you can see around return grilles
• A recent home renovation that created drywall dust
• You’ve lived in the home five or more years and have never had ducts cleaned

In Austin, where cedar pollen and construction dust are a year-round fact of life, we see ducts in some central neighborhoods that haven’t been opened since the home was built. A professional clean restores proper airflow, which can knock 5 – 15% off your cooling bill during a brutal July, and it removes the fine particulate that recirculates every time your AC runs.

How the Duct Cleaning Process Works at Brandt HVAC Co Austin

You’ll know exactly what’s happening at each step, and you’ll know the price before we start. Here’s our standard sequence.

1. Call and get a written price. You call (361) 326-1553, we ask about your home’s square footage, number of systems, and vent count, and we give you a firm written quote. No one shows up with an open-ended estimate.
2. Technician arrives by name and photo. Before the visit, you get the name and photo of the technician coming to your door. They arrive in uniform and show photo ID at the door. If anyone else shows up unannounced, that visit is on us, per the Threshold Verified standard.
3. Walkthrough and camera inspection. The technician walks your home with you, checks the return side and supply registers, and runs a camera through the main trunk lines so you can see the actual condition inside your ducts.
4. Source removal cleaning. We use a HEPA-filtered vacuum attached to the duct system, creating negative pressure while agitation tools loosen debris from the duct walls. This removes, rather than redistributes, the dust.
5. Sanitizer application (if needed). If the camera shows mold or bacteria, we apply an EPA-registered sanitizer. You’ll see the price for this on your written quote before we use it.
6. Filter replacement and final walkthrough. We install a fresh filter, show you the after photos from the camera, and answer any questions before we leave.

Every duct cleaning job is covered by our 365-Day Done Right Promise. If the job isn’t done right, we make it right. And if a problem we should have caught shows up within the year, the return visit is free. No argument, no additional charge.

How Much Does Air Duct Cleaning Cost Compared to Other HVAC Services?

Context helps. Here’s how duct cleaning stacks up against other common Austin HVAC expenses.

• Duct cleaning: $350 – $550 typical
• AC repair: $150 – $650, depending on the part
• Furnace repair: $150 – $700
• AC installation: $3,500 – $7,500 for a full system replacement
• Annual tune-up: $80 – $200

Duct cleaning sits in the low-to-mid range of HVAC expenses. For most Austin homeowners, it’s a once-every-three-to-five-year service, not an annual cost, which makes the per-year figure closer to $70 – $180. Compared to the cost of running an AC system with restricted airflow through clogged ducts, a clean system often pays for itself in lower utility bills within two cooling seasons.

FAQs – Duct Cleaning Cost

How much does duct cleaning cost in Austin?

Most Austin homes cost $350 – $550 for a full duct cleaning. Two-system homes run $700 – $900, and add-ons like sanitizing or coil cleaning can add $75 – $200. Call (361) 326-1553 for a free written estimate specific to your home.

Is it cheaper to clean or replace ducts?

Cleaning is almost always cheaper by a wide margin. Cleaning runs $350 – $550, while a full duct replacement in Austin costs $3,000 – $6,000 depending on home size and accessibility. Replacement only makes sense when ducts are collapsed, torn, or full of mold that can’t be removed. We’ll tell you honestly which one you need, and you’ll see the written price before any work starts.

Can you clean ducts in one day?

Yes. A standard single-system home in Austin takes 3 – 5 hours from arrival to final walkthrough. Larger homes or homes with significant buildup may take a full working day. When you call (361) 326-1553, we’ll give you a realistic timeframe for your specific home.

How often should ducts be cleaned in Austin?

Every three to five years for most homes. Homes with multiple pets, homes near construction, or homes with allergy-prone residents may benefit from cleaning every two to three years. Austin’s cedar pollen season and consistent dust load mean local ducts accumulate debris faster than in many other climates.

Does duct cleaning help with allergies?

It can, particularly for Austin’s cedar and oak pollen seasons. A 2026 professional duct cleaning removes the fine particulate that recirculates through your HVAC system every time the blower runs. If your ductwork hasn’t been cleaned in five or more years, the first cleaning often produces a noticeable difference in indoor air quality. We’ll show you before-and-after camera footage so you can see what was actually removed.

Do you give free estimates for duct cleaning?

Yes. Call (361) 326-1553 and a live person will answer. We’ll give you a firm written quote by phone based on your home’s specifics, and that quote won’t change when the technician arrives. That’s the no-hassle upfront pricing we’ve done since 2003, and it’s on every single job.
