Your energy bills drop. Not by a few dollars, but by 10% to 40% when leaky, poorly installed ducts get replaced with properly sealed ductwork that actually delivers air where it’s supposed to go.
Every room hits the temperature you set. No more bedroom that’s 10 degrees hotter than the living room. No more running the AC constantly just to make one space comfortable while freezing out another.
Your HVAC system stops working itself to death. When ductwork is installed correctly, your equipment doesn’t have to run twice as long to do half the job. That means fewer breakdowns, lower repair bills, and years added to your system’s life.
You stop circulating attic dust, insulation particles, and allergens through your home. New Braunfels homes deal with cedar pollen, oak pollen, ragweed, mold from humidity, and dust mites that thrive in our climate. Sealed ductwork keeps that stuff in the attic where it belongs, not in the air your family breathes.
Texas Air Repair is a veteran-owned company that’s been installing and replacing ductwork across San Antonio, Austin, and Houston since before New Braunfels became the booming suburb it is today. We’ve worked in homes built in the 2000s with original ductwork that’s falling apart, and brand new construction where builders cut corners on the install.
We’re not the cheapest option. We’re the honest one. No upselling, no scare tactics, no hidden fees after the job starts. Just licensed, EPA-certified technicians who know how to size, seal, and install ductwork that actually works in Texas heat.
New Braunfels sits in a unique climate zone where your attic can hit 150 degrees in summer and your ducts are sitting up there trying to push cold air through leaky seams. We account for that. We’ve seen what happens when installers don’t, and we’re the ones homeowners call to fix it.
We start with an honest assessment of your existing ductwork. That means going into your attic, crawl space, or wherever your ducts run, and checking for leaks, disconnections, crushed sections, and poor layout. We measure airflow at each vent and check whether your system is sized correctly for your home.
If replacement makes sense, we map out a new duct layout that eliminates the problems causing uneven temperatures and wasted energy. We calculate the right duct size for each room based on load requirements, not guesswork. Then we remove old ductwork and install new ducts using proper sealing methods and insulation rated for Texas attics.
Every seam gets mastic sealant, not just tape that falls off in the heat. Every joint is secured. Every vent is balanced so the right amount of air reaches each room. We test the system when we’re done to confirm airflow and temperature distribution actually match what your home needs.
You get a system that works the way it should have from day one. Most installations take one to three days depending on home size and duct complexity.

You’re getting ducts sized specifically for your home’s square footage, insulation, window exposure, and HVAC capacity. Not the generic layout that works “good enough” in most homes. The layout that works in your home.
You’re getting materials rated for the conditions in New Braunfels attics. That means insulation that handles extreme temperature swings, flex duct that won’t crack in the heat, and rigid ductwork where needed for long runs or high-pressure zones.
You’re getting proper sealing at every connection point using mastic and metal-backed tape, not the cheap fabric tape that peels off after one summer. You’re getting duct supports installed at the right intervals so ducts don’t sag, kink, or disconnect over time.
New Braunfels has a median home value of $339,400, and 31.7% of homes here were built between 2010 and 2019. That means a lot of houses are hitting the age where original ductwork starts failing. Builders often use the cheapest install methods to hit budget, and homeowners pay for it later in comfort and utility bills. Proper duct installation fixes that permanently.
You’re also getting technicians who clean up after themselves, respect your property, and explain what we’re doing as we go. No surprises, no mess left behind.
Most duct replacement projects in New Braunfels run between $1,400 and $5,600 depending on home size, duct accessibility, and how much of the system needs replacing. Homes in the 1,500 to 2,000 square foot range typically fall in the $2,400 to $4,200 range for a complete replacement.
The cost breaks down to about $25 to $55 per linear foot of ductwork, which includes materials, labor, sealing, insulation, and testing. Attic installations cost less than crawl space work because access is easier. Homes with complex layouts or multiple stories cost more.
If you’re only replacing sections rather than the entire system, costs drop significantly. But partial replacement only makes sense if the rest of your ductwork is in good shape. We’ll tell you honestly whether you need full replacement or if targeted repairs will solve your problems.
If your ducts are sagging, disconnected, crushed, or have visible holes and tears, replacement is the right move. Sealing only works when the duct structure itself is still intact.
If you’ve got major temperature differences between rooms, skyrocketing energy bills despite a working HVAC system, or excessive dust no matter how often you clean, those are signs your ductwork is failing. Homes built in the early 2000s often used flex duct that degrades after 15 to 20 years in Texas attics. Once that material starts breaking down, sealing won’t fix it.
We check duct condition during the assessment and show you exactly what we’re seeing. If sealing will solve the problem, we’ll tell you that. If the ducts are too far gone, we’ll explain why replacement is the only option that actually works long-term. You’ll know what you’re paying for and why before any work starts.
Yes, if your current ducts are leaking. The Department of Energy estimates that homes lose 20% to 30% of conditioned air through duct leaks, holes, and poor connections. In extreme cases, that number hits 40%.
When ducts leak in your attic, you’re paying to cool a 150-degree space instead of your living room. Your HVAC system runs longer, works harder, and uses more electricity to maintain temperature. Properly sealed and installed ductwork eliminates that waste.
Most New Braunfels homeowners see a noticeable drop in their electric bills within the first month after duct replacement, especially during summer when AC usage peaks. The exact savings depend on how bad your old ducts were and how much conditioned air was escaping. But if you’re currently losing 30% of your air to leaks, you’ll see that reflected in lower bills once the leaks are gone.
Most residential duct installations take one to three days. A straightforward replacement in a single-story home with good attic access usually wraps up in a day or two. Two-story homes, complex layouts, or difficult access points can push the timeline to three days.
We’re not rushing through the job to hit some arbitrary deadline. Proper installation means taking time to seal every joint, secure every section, and test airflow when we’re done. Cutting corners to finish faster is how you end up with the same problems you’re trying to fix.
Your AC or heat will be down during installation, so we work efficiently to minimize disruption. Most of the work happens in the attic or crawl space, not in your living areas. We schedule installations during milder weather when possible, but we also offer 24/7 emergency service if your system fails and you need immediate replacement.
You can, but you probably shouldn’t. Duct installation requires calculating proper sizing based on HVAC capacity, room load, and airflow requirements. Get those calculations wrong and you’ll have uneven temperatures, reduced efficiency, and potential damage to your HVAC equipment.
You also need to know how to seal ducts correctly using mastic and proper tape application, how to support ducts so they don’t sag or disconnect, and how to insulate for Texas attic conditions. Most DIY installations we’re called to fix have undersized ducts, poor sealing, inadequate support, and layouts that create airflow restrictions.
Texas requires HVAC contractors to be licensed for a reason. Improper duct installation can create negative pressure that pulls carbon monoxide into your home, cause mold growth from condensation, or create fire hazards near heat sources. The money you save upfront gets spent fixing problems later, usually with a full replacement anyway.
Flex duct is the ribbed, flexible tubing you see in most attics. It’s cheaper, faster to install, and works well for shorter runs and turns. But it degrades faster in extreme heat, can kink or sag if not supported properly, and creates more airflow resistance than rigid duct.
Rigid ductwork is metal, either galvanized steel or aluminum, and it’s more durable and efficient for long straight runs and high-pressure applications. It costs more and takes longer to install, but it lasts decades longer than flex duct in Texas attics.
Most homes use a combination. Rigid duct for main trunk lines and long runs, flex duct for branches to individual vents. That gives you durability where it matters and flexibility where you need it. We recommend what makes sense for your specific layout and budget, not what’s easiest for us to install.
