Ductwork, The Hidden Half.
Ten duct services for the half of your system nobody looks at: the attic and crawlspace network that decides whether the equipment you paid for actually reaches your rooms. Most comfort complaints live here, and most shops never check.

Your Equipment Is Only as Good as Its Delivery
A cooling system can be perfectly healthy and still fail your bedrooms, because the ductwork between the equipment and the registers is its own machine, and around here it is usually the neglected one. Boom-era houses inherited stamped duct designs with starved returns. Older homes carry attic archaeology, runs added, crushed, and abandoned across renovations. Leaky supply ducts dump paid-for air into 140-degree attics; leaky returns inhale attic dust and deliver it to your filter’s blind side.
The catalog below treats the duct system as the engineering it is: design for new work, repair and modification for the damaged and the badly-routed, sealing and insulation to stop the attic tax, leakage testing that measures instead of guesses, cleaning where it is honestly warranted, and return-air work, the most underbuilt piece of almost every Texas house we open.
The measurement point deserves emphasis because duct work is where vague upsells thrive: our duct diagnostics run on numbers, static pressure at the equipment, airflow at every register, leakage quantified by test, and the findings arrive as a written map of your specific house. This room receives sixty percent of its target. This return is half the size the math wants. This run loses this much crossing the attic. The corrections then get quoted against the map in honest priority order, cheapest-highest-leverage first.
A word on duct cleaning specifically, because the coupon industry has poisoned the term: cleaning has legitimate cases, post-construction debris, rodent history, documented contamination, and a long list of illegitimate ones where sealing or filtration is the real answer. Our cleaning page explains the difference bluntly. We turn down cleaning jobs that will not help, because the alternative is charging you to not fix your problem.
And the return-air paragraph, since it is the most common finding on the whole page: Texas production houses were built supply-rich and return-poor, and a room that cannot exhale cannot inhale. Undersized returns strangle airflow, pressurize closed bedrooms, and make the equipment strain against its own ductwork every runtime hour. Return-side corrections are routinely the highest-leverage dollars on any duct quote we write.

How This Work Gets Run
Here is what hiring us for this work looks like, start to finish: a phone call that reaches a person who can actually diagnose, an honest window with the drive figured in, instruments on the system until the real cause shows itself, a straight explanation with the real price attached, your go-ahead before anything happens, and verification before departure. The same standard covers a two-mile call in Burnet and a sixty-mile call at the edge of the map, because distance changes the drive and nothing else about the work.
Money gets handled the Burnet way on every page in this category: the visit cost stated on the phone before a truck rolls, the repair or install price stated after diagnosis and before work, no surprise line items, and no commission structure anywhere in the company steering the recommendation toward the expensive answer. When the honest move is the cheap fix, you hear the cheap fix. When the honest move is not spending money at all, a settings change, a warranty claim we can file instead, you hear that too, because the long game in a sixteen-county market where everyone talks is the only game worth playing.
This category, like everything in the catalog, lives on Central Texas time: five-plus months of cooling duty that doubles what most of the country asks of equipment, winters that spend their fury in short brutal bursts, lake humidity that keeps the biology and corrosion clocks running all year, and limestone country that soaks up afternoon heat and radiates it back into the evening. Equipment out here ages on an accelerated schedule, which is why the maintenance rhythm gets preached on every page of this site, and why the trucks stock for the failures this climate actually produces instead of a national average. The weather sets the terms. The preparation decides who wins.
Coverage and the Long Game
Everything on this page is available everywhere we run: Burnet and the lake towns at home-county speed, the Georgetown-to-Round-Rock corridor on weekly routes, Austin, the Bell County post towns, and the far edges of the map at honest stated windows. After-hours coverage is real, a technician answers the phone at 2 AM the same as at 2 PM, and the emergency doctrine on the emergency page applies to this category in full. The cheapest version of every service below is still the maintenance visit that makes it unnecessary; the maintenance page makes that case with a decade of route data.
The Shop Behind the Work
A word about who shows up when you book anything on this page: a second-generation shop, not a franchise dispatch. Bryce grew up in this trade, learned it in attics and crawlspaces before the company had a name on a truck, and built Off Duty around three habits the reviews keep confirming, show up when you say you will, explain the problem to the point, charge a fair price for work that holds. The Diamond Contractor badge covers the ductless work with factory training and doubled warranties, the JB authorization covers warranty repairs with the paperwork handled, and the 24-hour phone covers everything else. Small shop, sixteen counties, one standard.
Booking It
Booking any of this work follows the same short path: call (512) 925-3090 or send the contact form, describe what the system is doing in your own words, weak airflow, warm air, weird noise, whatever it is, and get an honest window with the drive time already figured in. The truck arrives stocked for this category’s common failures, the diagnosis runs on instruments, the price gets said out loud before work starts, and the finished job gets verified before we leave. First-time customers get the same standing as ten-year ones, and the file we start on your first visit makes every future call faster and smarter.
Ductwork Questions
Asked Before Booking
How do I know if my ducts are the real problem?
The symptoms have a pattern: rooms that never match the thermostat, especially far ones and upstairs ones, dust that returns fast after cleaning, doors that whistle or slam from pressure, bills that outrun the equipment’s rating, and a system that seems to run constantly for mediocre results. Any of those justifies the measured assessment, static pressure, register flows, leakage test, which replaces years of guessing with an afternoon of numbers. The written findings then make the fix list obvious, and plenty of houses need less correction than their owners feared.
Is duct sealing actually worth the money?
On leaky systems, it is some of the best money in the trade: typical unsealed ductwork loses a meaningful slice of every conditioned air dollar into the attic, and sealing recovers capacity you already own, which beats buying more capacity at equipment prices. The honest qualifier is the word leaky, which is why we test before quoting, the leakage number decides whether sealing is a transformation or a nice-to-have for your specific house. Sealed and insulated ducts also stop inhaling attic air, which shows up as less dust and better air alongside the lower bills.
How fast can you get out for this kind of work?
Depends on where you are and what failed, and the window you hear on the phone will be the honest version of both. Home-county calls routinely land same-day, corridor and lake-town calls ride scheduled weekly routes with same-week the norm, and genuine emergencies jump every queue around the clock. What never happens is a fabricated arrival time to end the phone call: the window stated is the window kept, drive included, per the policy that runs the whole company. Describe the symptom when you call, because it changes the triage, and a real diagnosis often starts right there on the phone.
Do you actually do all of these services, or is this a menu of maybes?
Every service listed on this page is work we actually perform, with its own full page behind the link explaining exactly how we run it. The catalog is 147 services deep because Central Texas systems fail 147 different ways, and a decade in the trade has put our hands on all of them. The trucks stock for the common failures in this category specifically, the specialty work schedules like specialty work should, and when something genuinely sits outside our lane, which is rare, you hear that on the phone instead of after a wasted visit.
What does a service call cost for this category?
The visit cost gets stated on the phone before any truck moves, and the work itself gets priced after diagnosis and before repair, out loud, in plain English. No category on this site carries teaser pricing, because printed teaser numbers turn into invoice arguments, and we would rather tell you the truth from the start. Larger projects in this category get written quotes with the scope itemized, financing options get discussed with real numbers when asked, and warranty coverage gets checked before work begins so covered failures cost you a claim instead of a repair.
