Your monthly energy bill drops because you’re no longer paying to cool your attic. Every room in your home reaches the temperature you set on the thermostat, not just the ones closest to your air handler. Your HVAC system stops running constantly because it’s not fighting against leaks and poor connections.
When replacing ac ducts in Sandy Oaks homes, we see the same pattern. Homeowners have been losing around 30% of their treated air through gaps, cracks, and deteriorated connections. That’s not a minor inefficiency—that’s throwing away nearly a third of what you’re paying for every single month.
The difference shows up immediately. Your system cycles properly instead of running nonstop. Hot spots disappear. And when summer hits and attic temperatures climb past 140 degrees, your new ductwork holds up instead of cracking under thermal stress like the old stuff did.
Texas Air Repair is a veteran-owned company that’s been handling HVAC work across San Antonio, Austin, and Houston since 2005. We know what Sandy Oaks ductwork deals with—the humidity rolling in from San Antonio, the dust that kicks up during dry spells, and attic conditions that destroy poorly installed systems in just a few years.
Our team holds the certifications and licenses you’d expect, and we maintain an A+ rating with the Better Business Bureau. But what matters more is that we show up when we say we will, we quote the job accurately before we start, and we don’t leave until the system is tested and working right.
Sandy Oaks is a quiet town, and people here expect straight answers. That’s what you’ll get from us—no upselling, no hidden fees, just honest work that holds up in this climate.
We start by pulling out all the old ductwork—every piece of it. Installing new ducts over old ones creates airflow problems and reduces efficiency, so complete removal is the only way to do this right. That includes the ducts themselves, the insulation, and all the connecting materials that have been sitting in your attic for years.
Next comes proper sizing. We calculate the airflow your system needs based on your home’s square footage and layout. Undersized ducts create weak airflow and rooms that never reach temperature. Oversized ducts waste energy and create pressure imbalances. We size it correctly the first time.
Then we install rigid metal ductwork designed for Texas climate extremes. Metal handles the thermal stress better than flexible systems and maintains consistent airflow over time. Every joint gets sealed properly, every connection is secured, and insulation goes on to prevent condensation and energy loss.
Finally, we test the whole system. We verify airflow, check for leaks, and make sure every room is getting the conditioned air it should. Most installations take one to three days depending on your home’s size. You’ll feel the difference as soon as we’re done.
Ready to get started?
You get complete removal and disposal of all existing ductwork, not a patch job over failing systems. We handle the sizing calculations, material selection, and installation using professional-grade components built for this climate. Every connection is sealed with mastic or metal-backed tape—never cloth duct tape, which fails in attic heat.
Insulation goes on every section of ductwork to prevent energy loss and condensation problems. In Sandy Oaks, where humidity can be an issue, proper insulation isn’t optional. It’s what prevents moisture damage and keeps your system efficient year-round.
We also include complete system testing and balancing. That means checking airflow at every register, verifying temperature consistency across rooms, and making sure your HVAC system is operating at the efficiency it was designed for. Most homeowners in the area pay between $1,500 and $5,000 for duct installation depending on home size and complexity, and that investment typically pays for itself within a few years through lower energy bills.
You also get our warranty on parts and labor, plus access to our 24/7 emergency service if anything comes up. We’re local, we’re licensed, and we’ll be here if you need us.
Most residential air duct installations take between one and three days. A straightforward replacement in an average-sized home usually wraps up in a single day. Larger homes or jobs that involve complex layouts, multiple stories, or difficult attic access can take two to three days.
The timeline depends on how much old ductwork needs to come out, how accessible your attic space is, and whether we’re working around any structural obstacles. We’ll give you an accurate estimate after we assess your specific situation.
What matters more than speed is doing it right. Rushing a duct installation leads to leaks, poor connections, and systems that fail within a few years. We take the time to remove everything properly, size the new system correctly, and test it thoroughly before we leave.
If your ductwork is more than 15 years old, showing multiple leaks, or has insulation damage from attic heat, full replacement makes more sense than patching individual sections. Repairs might save money upfront, but they don’t address the underlying problem—aging materials that are breaking down throughout the system.
Sandy Oaks homes with attic ductwork face thermal stress that most systems weren’t built to handle long-term. Attic temperatures above 140 degrees during summer months cause insulation to deteriorate, connections to loosen, and flexible ducts to crack. Patching one leak doesn’t fix the others you can’t see yet.
Complete replacement also gives you the chance to resize the system properly, upgrade to better materials, and seal everything with professional-grade methods. Most homeowners who choose partial repairs end up calling us back within a year or two to finish the job. Starting with full replacement saves you that second bill and gets your efficiency gains immediately.
Extreme heat is the main culprit. Attic temperatures in this area regularly exceed 140 degrees during summer, and that thermal stress breaks down insulation, loosens connections, and causes flexible ductwork to crack over time. Materials that would last 20 years in a climate-controlled space might only last 10 to 15 in a Texas attic.
Humidity also plays a role. When humid air from San Antonio moves through the area, it can cause condensation problems if your ductwork isn’t properly insulated. That moisture leads to mold growth, insulation damage, and reduced efficiency.
Poor installation is another common cause. Ducts that weren’t sized correctly, connections sealed with cloth tape instead of mastic, or insulation that was installed incorrectly all fail faster under stress. We see plenty of systems that were installed cheap and fast, and they’re falling apart within five to seven years. Quality installation using the right materials for this climate is what makes ductwork last.
Most homeowners in the Sandy Oaks area pay between $1,500 and $5,000 for complete duct replacement, depending on home size, system complexity, and material choices. Smaller homes with straightforward layouts fall on the lower end. Larger homes, multi-story layouts, or jobs requiring extensive attic work cost more.
The price includes removing all old ductwork, properly sizing the new system, installing professional-grade materials, sealing every connection, adding insulation, and testing the completed system. We don’t quote by linear foot alone because that doesn’t account for the labor involved in removal, the complexity of your layout, or the quality of materials used.
What you’re really paying for is stopping that 30% energy loss that’s been driving up your bills. Most systems pay for themselves within three to five years through reduced energy costs. We’ll give you an exact quote after we assess your home—no surprises, no hidden fees, just a clear number before we start work.
Yes, if your ductwork runs through the attic. Most Sandy Oaks homes have attic-based duct systems, which means we can access everything from above without touching your ceilings or walls. We work entirely in the attic space, removing old ducts and installing new ones through existing access points.
The only time ceiling work becomes necessary is if you have ducts running through interior walls or if you’re adding new vents in rooms that didn’t have them before. But for standard replacement of existing attic ductwork, your interior spaces stay intact.
We do need clear access to your attic, and we’ll protect your home with drop cloths and careful material handling. The work happens above you, not around you, which means less disruption and faster completion. You’ll hear us working, but you won’t see construction mess in your living areas.
Yes, we provide 24/7 emergency service for HVAC issues including major duct failures. If your system stops working because of a significant duct problem—like a complete disconnection, major leak, or damage from pests or water intrusion—we can get someone out to assess the situation and provide temporary solutions if needed.
Emergency repairs typically focus on getting your system functional again quickly, especially during extreme weather. That might mean sealing a major leak, reconnecting a section that’s come loose, or isolating a damaged zone so the rest of your system can operate.
For most duct problems, though, full replacement is the better long-term solution. We’ll be honest about whether an emergency repair will actually solve your problem or just buy you a few weeks before the next failure. Our goal is to fix it right, not just patch it temporarily so we can charge you again next month.
