Your AC runs all day. Your upstairs is still hot. Your energy bill keeps climbing. That’s what happens when ducts leak air into a 120-degree attic instead of delivering it to your rooms.
Replacing ducts in attic spaces isn’t just about comfort. It’s about stopping the waste. Properly sealed and installed ductwork means the air you’re paying to cool actually reaches the rooms where you live. That’s lower bills, even temperatures, and an HVAC system that doesn’t have to work itself to death every summer.
In Scenic Oaks, where homes are larger and expectations are higher, your ductwork needs to handle the load. If it’s undersized, poorly sealed, or routed wrong, you’ll feel it in every room. We size ducts based on your home’s actual airflow needs, seal every joint to SMACNA standards, and install insulation that keeps cool air from bleeding into unconditioned spaces. You get the cooling you paid for, in every room, without the waste.
We’ve been installing and replacing AC ducts in Scenic Oaks, TX and across the San Antonio area since 1995. We’re EPA-certified, veteran-owned, and we’ve seen what Texas heat does to poorly installed ductwork in homes like yours.
We’re not the cheapest option, and we’re fine with that. You’re not looking for duct tape and hope. You’re looking for ductwork that’s sized right, sealed tight, and installed to last through decades of 100-degree summers. That’s what we do—and we’ve been doing it long enough to know what works in larger homes where airflow matters.
When you call, you’re talking to people who understand how Scenic Oaks homes are built, how your HVAC system should perform, and what it takes to get your ducts right the first time.
We start with a load calculation. That tells us how much air each room needs based on size, sun exposure, and how your home is laid out. No guessing. No reusing old duct sizes that were wrong to begin with.
Next, we map the duct layout. We’re looking at the shortest, most efficient routes from your air handler to every register. We avoid unnecessary bends, keep runs insulated in unconditioned spaces, and make sure return air has a clear path back. If your attic ducts are buried under insulation or routed through tight spaces, we fix that.
Then we fabricate and install. All ductwork is built to SMACNA standards and sealed at every seam with mastic or metal-backed tape—not the stuff that falls off in two years. We insulate ducts running through your attic to R-6 or R-8, depending on code and conditions. Every connection is airtight. Every register is balanced. When we’re done, your system moves air the way it was designed to, and you’ll feel the difference in every room.

You get ductwork that’s sized to your home’s actual cooling load, not a generic estimate. In Scenic Oaks, where homes regularly exceed 3,000 square feet, undersized ducts create pressure imbalances that make your system work harder and cool less effectively. We calculate the CFM requirements for each zone and size ducts accordingly.
You get sealed connections that don’t leak. Studies show that 20% to 30% of conditioned air is lost through duct leaks in typical homes. We seal every joint with mastic or foil-backed tape, test for leaks, and insulate ducts in unconditioned spaces to prevent thermal loss. That’s air—and money—staying where it belongs.
You get code-compliant installation that won’t cause problems down the road. We pull permits, follow local building codes, and install to manufacturer specs. Your ducts are inspected, documented, and ready to perform without worry. And because we’ve been doing this in the San Antonio area for over 20 years, we know what inspectors look for and what homeowners need for long-term performance in Texas heat.
For most homes in Scenic Oaks, full duct replacement runs between $5,000 and $12,000, depending on home size, duct layout, and accessibility. Larger homes with complex layouts or ducts running through difficult attic spaces will be on the higher end. Smaller homes or partial replacements cost less.
That price includes removing old ductwork, fabricating new ducts to the correct size, sealing all joints, insulating runs in unconditioned spaces, and balancing airflow to each room. It also includes permits and inspections if required by local code. You’re not just getting new metal—you’re getting a system designed to move air efficiently and keep your home comfortable without wasting energy.
If you’re only dealing with a section of damaged ductwork or need to add ducts for a new addition, costs drop significantly. We can give you an accurate estimate after seeing your home’s layout and understanding what your HVAC system needs to perform the way it should.
Most residential duct installations take two to four days, depending on the size of your home and how accessible your attic or crawl space is. If we’re replacing ducts in attic spaces that are tight, poorly lit, or buried under insulation, it takes longer. If your home has a straightforward layout and good access, we move faster.
We’re not rushing. Ductwork that’s installed quickly and poorly will leak, rattle, and cost you money every month. We take the time to fabricate ducts to the right dimensions, seal every connection properly, and insulate runs that need it. That means your installation is done right, and you won’t be calling us back to fix leaks or rebalance airflow.
You’ll have full use of your HVAC system as soon as we’re done. We test everything before we leave—airflow, temperatures at each register, and system performance. If something’s not right, we fix it before we pack up.
Yes. If your Scenic Oaks home was built without ductwork or you’re converting from window units to central air, we design and install a complete duct system from scratch. That includes sizing ducts based on your home’s cooling load, routing supply and return ducts through attics or crawl spaces, and installing registers in each room.
New duct installation costs more than replacing existing ducts because we’re starting from zero. Expect to pay between $2,400 and $6,600 for a full system in a typical home, though larger homes or complex layouts will cost more. That price includes everything—design, fabrication, installation, insulation, sealing, and balancing.
We work with your HVAC contractor (or handle the full HVAC installation ourselves) to make sure your new duct system matches your equipment. Ducts that are too small create pressure problems. Ducts that are too large waste money and reduce efficiency. We size everything correctly so your system works the way it should from day one.
Flexible ductwork is lighter, faster to install, and works well for shorter runs or tight spaces where rigid ducts won’t fit. It’s made from a wire coil covered in insulated plastic, and it’s common in residential attics. The downside is that it can sag, kink, or compress if not installed correctly, which restricts airflow and makes your system work harder.
Rigid ductwork—either sheet metal or duct board—is more durable and maintains consistent airflow because it doesn’t sag or compress. It’s better for long runs, main trunk lines, and areas where ducts are exposed or need to last decades without maintenance. It costs more and takes longer to install, but it performs better over time.
In most Scenic Oaks homes, we use a combination. Rigid ducts for main trunk lines and long runs, flexible ducts for shorter branches to individual registers. That gives you the durability and airflow of rigid ducts where it matters, with the flexibility and cost savings of flex duct where it makes sense. We don’t use one type everywhere just because it’s easier—we use what works best for your home’s layout and your system’s performance.
You’ll notice uneven temperatures between rooms. One bedroom is freezing while another stays warm no matter how long the AC runs. That’s a sign that air isn’t reaching certain areas because it’s leaking out before it gets there.
Your energy bills will climb without explanation. If your usage hasn’t changed but your bills keep going up, leaking ducts are often the reason. You’re paying to cool air that’s escaping into your attic or crawl space instead of cooling your home. In Scenic Oaks, where AC systems run hard all summer, that waste adds up fast.
You might also hear whistling or rattling from your ducts when the system runs. That’s air escaping through gaps or loose connections. Dusty rooms, weak airflow from certain registers, or an HVAC system that runs constantly without keeping up are all signs your ducts aren’t doing their job. We can test for leaks, measure airflow, and tell you exactly where the problems are and what it’ll take to fix them.
Yes. We pull permits when required, coordinate inspections, and make sure your duct installation meets local building codes in Scenic Oaks, TX. You don’t have to deal with the city or county—we handle that from start to finish.
Permits aren’t always required for duct repairs or small sections of replacement, but they are required for full system installations or major modifications. Inspectors check for proper sizing, sealing, insulation, and code compliance. If your ducts don’t pass, you’ll have to tear things apart and redo the work. We install it right the first time so that doesn’t happen.
Code-compliant ductwork also protects your home’s resale value. If you ever sell, buyers and inspectors will look at your HVAC system. Unpermitted or poorly installed ducts raise red flags and can kill deals. We document everything, keep records of inspections, and make sure your installation is clean, legal, and ready to perform for years.
