When your ducts are installed right, your home cools evenly. No more hot bedrooms while the living room freezes. No more running the AC longer just to get one room comfortable.
You’ll see it on your energy bill first. Most homeowners in Timberwood Park see 15-25% reductions after replacing ac ducts that were leaking into the attic. That’s real money back every single month.
But the bigger shift is air quality. Properly sealed ductwork stops pulling in attic dust, insulation fibers, and allergens. Your system only circulates the air it’s supposed to—filtered, conditioned, clean. If anyone in your house deals with allergies or asthma, that difference is immediate.
The Hill Country climate makes this even more important. Cedar pollen, limestone dust, and dry summer air all get pulled into poorly sealed ducts. Once they’re in your system, they’re in every room. Replacing ducts in attic spaces with modern, sealed systems cuts that cycle off at the source.
We’re veteran-owned and have been installing HVAC systems across San Antonio, Austin, and Houston for over 20 years. We’re not new to Timberwood Park’s climate or the way homes are built out here.
We know how attic heat affects duct performance. We know what happens when ducts aren’t sized right for your square footage or when installers skip the sealing step to save time. We’ve seen it all, and we’ve fixed it all.
Our team is certified, local, and available 24/7 if something goes wrong. We’re not the cheapest option in town, and we won’t pretend to be. But if you want ductwork installed correctly the first time—sized right, sealed tight, and built to last in Texas heat—that’s what we do.
First, we come out and assess your current system. We’re looking at duct condition, airflow balance, insulation levels, and whether your existing layout even makes sense for how you use your home. This isn’t a sales call—it’s a real evaluation.
If replacement makes sense, we’ll map out a new duct design that matches your system’s capacity and your home’s layout. We calculate the load for each room so airflow is balanced. No guessing.
Installation typically takes one to two days depending on your home size. We remove old ductwork, install new insulated ducts, seal every joint with mastic, and test the system for leaks before we leave. You’ll feel the difference the first time your AC kicks on.
We handle permits and inspections. You don’t have to call the county or figure out code requirements—we take care of it. Once the job is done, your ducts are code-compliant, sealed, and ready to run efficiently for the next 15 to 20 years.

When we install new ductwork, you’re getting a complete system—not a patchwork fix. That means properly sized ducts for your HVAC capacity, insulated to R-6 or R-8 depending on your attic conditions, and sealed at every connection point with mastic and foil tape.
We also balance the airflow. A lot of homes in Timberwood Park have rooms that never get enough air because the ducts weren’t designed with load calculations. We fix that during installation so every room gets the CFM it actually needs.
In the Hill Country, your attic can hit 140°F in summer. If your ducts aren’t insulated properly, you’re losing conditioned air before it even reaches your vents. We use insulated flex duct or sheet metal with external insulation wrap, depending on your system and budget.
We also include a full system test and blower door analysis if needed. That tells us exactly how much air you’re losing and confirms the new ducts are performing the way they should. Most homes we work on go from 25-30% duct leakage down to under 5%. That’s the difference between wasting money and actually cooling your house.
If your ducts are over 15 years old, you’re probably looking at replacement. Ductwork starts to fail at the seams, joints, and connection points after that much time, especially in Texas attics where temperature swings are extreme.
Repair makes sense if the damage is localized—maybe one section got crushed or disconnected. But if you’re dealing with multiple leaks, poor airflow in several rooms, or ducts that were never installed correctly in the first place, replacement is the smarter move.
We’ll tell you honestly which one makes sense after we assess your system. There’s no point in patching ductwork that’s going to fail again in two years. And there’s no point in replacing ducts that just need a simple fix.
Most homes take one to two days for a complete duct replacement. Smaller homes or simpler layouts might be done in a day. Larger homes with complex HVAC zoning or multiple stories can take two full days.
The timeline depends on how accessible your attic or crawlspace is, how much old ductwork needs to be removed, and whether we’re also upgrading your HVAC unit at the same time. We’ll give you an accurate estimate after the initial assessment.
We work efficiently, but we don’t rush. Every joint gets sealed. Every section gets tested. You’re not paying for speed—you’re paying for ductwork that actually works the way it’s supposed to for the next 15 to 20 years.
If your current ducts are leaking 20-30% of your conditioned air into the attic—which is common in older systems—then yes, new ducts will make a significant difference. Most homeowners see a 15-25% reduction in cooling costs after proper duct replacement.
That’s not a guarantee, because your bill also depends on your insulation, windows, thermostat habits, and how efficient your HVAC unit is. But ducts are one of the biggest energy losses in most homes, especially in Timberwood Park where attics get brutally hot.
The ROI on duct replacement usually pays for itself in 5 to 7 years through energy savings alone. After that, it’s pure savings every month. And your home will be more comfortable the entire time, which is harder to put a price on.
Yes, and that’s actually the best time to do it. When you’re replacing your HVAC unit, we can design and install ductwork that’s perfectly matched to the new system’s capacity and airflow requirements.
A lot of older homes have ducts that were sized for a different unit or a different efficiency standard. If you install a new high-efficiency AC but keep old leaky ducts, you’re not getting the performance or savings you paid for.
We handle both installations at once, so you’re not dealing with two separate projects or two different crews in your attic. One job, one timeline, and a complete system that works together the way it should.
Yes. We pull the permits, schedule the inspections, and make sure everything is up to code before we close out the job. You don’t have to call Bexar County or figure out what’s required—we handle it.
Texas has specific codes for duct insulation, sealing methods, and airflow testing, especially if you’re in a newer home or doing work that requires a permit. We know those codes and we follow them on every install.
Once the inspection passes, you’ll have documentation that the work was done right. That matters if you ever sell your home or if your insurance company asks for proof of code-compliant work after a claim.
Flex duct is lighter, easier to install in tight attic spaces, and costs less. It’s insulated, flexible, and works well for most residential applications. Metal ductwork—usually galvanized steel—is more durable, lasts longer, and handles higher airflow without sagging or kinking.
We use both depending on your home’s layout and your system’s needs. Flex duct works great for branch runs to individual rooms. Metal duct is better for main trunk lines where airflow volume is higher and you need something that won’t degrade over time.
There’s no one-size-fits-all answer. We’ll recommend what makes sense for your home, your budget, and how long you plan to stay there. Both options work when they’re installed correctly—and that’s the part that matters most.
