Austin Duct Cleaning
What Ends Up in an Austin Duct System
Ductwork in Austin lives in the attic, and an Austin attic is not a clean place. Blown-in insulation drifts, roofing dust settles, and every summer the temperature up there passes 130 degrees, which dries out duct tape and mastic and opens joints. Once a return duct leaks, the air handler pulls attic air, fiberglass and dust straight into the supply side, and it has been doing that for years by the time anyone notices. Add a couple of decades of cedar and oak pollen, pet hair and a kitchen remodel or two, and you have what we find in a typical 1990s Round Rock or Pflugerville duct system.
Older central Austin homes have their own version: ductwork added in the 1970s or 80s to a house built without any, often running through crawl spaces as well as attics, with joints that were never sealed. Newer homes in Leander, Hutto and Kyle are usually cleaner inside the ducts but often have construction debris, drywall dust and sawdust, left from the build. Different houses, different jobs, and we look before we quote.
How duct cleaning works, the equipment involved and what it does and does not fix are explained on our duct cleaning page. This one is about Austin ductwork.

Do You Need It?
When Duct Cleaning Makes Sense for an Austin Home
Duct cleaning is not an annual service. These are the situations where it earns its cost.
-
You just bought an older Austin home
No service history, previous owners with pets or smokers, decades of pollen. A cleaning resets the system before you live with it.
-
A renovation just finished
Drywall sanding and demolition dust get into open registers and returns. Very common after kitchen and bath remodels in central Austin.
-
Visible debris at the registers
Dust puffing out when the system starts, or fuzz and insulation on the grille. That is material inside the duct, not on the filter.
-
A musty smell from the vents
Moisture in the ducts, often near the air handler after a condensate overflow. Cleaning helps; fixing the moisture source is essential.
-
Evidence of rodents or insects
Attic ducts are a highway for them. Droppings and nesting in ductwork need removal, and the entry point sealed.
-
Allergies that improved elsewhere and not at home
If a good filter has not helped, what is already in the ducts may be the problem. We can look with a camera and tell you.
The Service
Duct Cleaning and Ductwork Services in Austin
Cleaning is one step. The inspection, sealing and filtration around it are what keep the ducts clean.
- Whole-system duct cleaning Supply and return trunks, branch runs, registers and the air handler cabinet, with the debris captured rather than blown into the house.
- Duct inspection A look inside before and after, so you see what was there and what is not anymore.
- Duct sealing Closing the attic leaks that let dust in and conditioned air out. In an Austin attic, this is where most of the payoff is.
- Aeroseal Sealing leaks from inside the ductwork, for duct systems buried in insulation or otherwise hard to reach.
- Filtration upgrades A better filter at the air handler so the cleaned ducts stay that way through the next cedar season.
- Duct repair and replacement Crushed flex, disconnected boots and undersized runs. Sometimes the right answer is new ductwork, and we will say so.

Our 18 year old HVAC system finally gave out this past week, so we reached out to Radiant to see what could be done. They sent a tech out named Bryan the same day, and he did a great job looking over the entire HVAC system. He was friendly and helpful in explaining everything that he saw, and our options moving forward. We decided to replace the entire system, so we met with Jacob (same day thankfully) to find the best HVAC system for our needs. Jacob was friendly, professional, and did a great job explaining the different options on offer. Radiant was able to set-up next day install, which was much appreciated, because the temps were still going to be cold in the coming days.
The install team consisted of Carlos and Pablo, who were very courteous and professional, and were kind enough to answer any questions I had regarding the install. They did a great job installing our new HVAC system, and were tidy which is always appreciated! Before they left, they explained everything that had been done, and showed me photos of the work.
Our entire experience from start to finish was great. I appreciate that they send photos of who is coming to your home too. Friendly, kind, professional team members, and good work all the way around. Thanks Radiant!

I was totally shocked at that and the service call was only $39!!…. Highly recommend them Danielle showed up and he was a great guy and he put up with all my wishy-washiness and I had to hurry him because I was heading to church and he got caught in a lot of traffic getting here he even would’ve installed the part that broke but I Didn’t have the time tonight….. He was patient with me and just told me to call the office first thing in the morning and get a service call set up…. Thank you so much Radiant!!….

Alex performed the winter service on my unit. This business along with Alex, are very professional and upfront about everything. To be transparent, this is the maintenance included with the purchase of a unit from them. I was informed about everything to include pictures as proof. I was told that my unit is 100% and very clean and again pictures to prove it. I was reccomended this business by a friend and glad he did. The initial purchase experience was also amazing. I had contacted 5 other businesses to get quotes about a new unit as my upstairs unit failed. 2 were outrageous quotes and I am technically still waiting on the other 3. On every instance of getting a quote, I waited about 1 week. Luckily my house has two units but still, un acceptable especially during the summer. I guess they all had so much business they did not care for mine. When I called this business not only did they come out the same day, I had the new unit installed with in 48 hrs. Oh and let's not forget the quote they gave me was the lowest of all. I can say enough good things about this business. Keep up the great work.

Austin Duct Cleaning Questions
How often should ducts be cleaned in Austin?
Not on a schedule. Duct cleaning is a corrective service, not maintenance like a tune-up. A typical Austin home might need it after buying an older house, after a renovation, after a pest problem or a water event, or when a visual inspection shows real buildup. Between those, keeping the ducts clean is about a good filter changed on time and ducts that are sealed so attic dust cannot get in. If someone offers you a cheap annual duct cleaning, be cautious; the price usually grows at the door. We inspect first and tell you honestly whether yours needs it, and it is often paired with an AC tune-up when it does.
Why is there insulation and dust coming out of my vents?
Because a return duct or the air handler cabinet is leaking in the attic. When the blower runs, the return side is under suction, and any gap pulls in attic air along with loose blown-in insulation and dust, which then goes through the coil and out the supply registers. It is one of the most common findings in 1990s and 2000s homes across Round Rock, Cedar Park, Pflugerville and Buda, where the original duct connections have baked through 20-plus summers. Cleaning removes what is already in the ducts, but sealing the leak is the real fix, and it lowers your cooling bill at the same time.
Can you clean the ductwork in an older central Austin house with a crawl space?
Yes. A lot of pier-and-beam homes in Hyde Park, Crestview, Tarrytown and Travis Heights have ductwork running under the floor, added decades after the house was built, sometimes with a mix of metal, ductboard and flex in the same system. Crawl-space ducts collect moisture and, occasionally, wildlife, and they are hard to inspect without the right equipment. We look at them with a camera first, clean what can be cleaned, and tell you plainly if a section is too deteriorated to save. Old ductboard in particular sometimes needs replacement rather than cleaning, and we will show you why before recommending it.
Will duct cleaning help my allergies during cedar season?
It can, if the ducts are holding a load of old pollen and dust that gets stirred up every time the system runs. It will not stop new cedar pollen from coming in; that is the job of filtration and sealed returns. The honest answer for most Austin allergy sufferers is a combination: clean the ducts once if they need it, upgrade to a filter that actually catches cedar pollen, seal the return leaks and, for serious cases, add a whole-home purifier. Our Austin air quality page lays out those options, and we will tell you which ones your house actually needs.
