Your AC works twice as hard in Helotes summers. When your ducts leak or weren’t sized right from the start, you’re paying to cool your attic instead of your living room.
Proper air duct installation means every room hits the temperature you set. No more 78 degrees in the hallway and 85 in the back bedroom. Your system runs less, breaks down less, and your August CPS bill doesn’t make you wince.
You also breathe cleaner air. Sealed, well-installed ductwork keeps cedar pollen, attic dust, and outdoor allergens where they belong – outside. That matters here, where homes stay sealed up eight or nine months a year and Hill Country cedar hits hard every winter.
We’re a veteran-owned HVAC company that’s been installing and replacing ducts in attic spaces, crawlspaces, and new construction across San Antonio, Houston, and Austin for over 20 years. We’re not new to Helotes, and we’re not new to the specific challenges Hill Country homes face.
We know what happens when builders cut corners on ductwork. We know how fast insulation degrades in a Texas attic. And we know that most comfort problems aren’t your AC unit – they’re the ducts feeding it.
Our crews are certified, our pricing is transparent, and we’re available 24/7 if something goes wrong. We don’t upsell. We show you what’s broken, explain why it matters, and let you decide.
First, we come out and assess your current system. That means checking for leaks, measuring airflow at each vent, and looking at how your ducts were originally sized and routed. Most homes in Helotes were built after 2000, but that doesn’t mean the ductwork was done right.
Next, we design a system that matches your home’s layout and your AC’s capacity. We calculate the right duct sizes for each room, plan the most efficient routes, and make sure everything meets local building codes. If we’re replacing ducts in attic spaces, we also plan for proper insulation and sealing – critical in a climate where attics hit 150 degrees in summer.
Then we install. We pull permits, remove old ductwork if needed, and install new ducts with proper hangers, sealed joints, and insulated runs. We test airflow at every register and make sure your system is balanced before we leave. You’ll feel the difference the first time your AC cycles on.

A complete air duct installation in Helotes, TX includes removing old, damaged ductwork and installing new runs sized specifically for your home and HVAC system. We use rigid or flex duct depending on the application, seal every joint with mastic (not just tape), and insulate runs that pass through unconditioned spaces like attics.
We also install new registers and grilles, balance airflow across all rooms, and test for leaks using industry-standard equipment. In Helotes, where your AC runs 800 to 1,200 hours every summer, proper sealing isn’t optional. Leaking ducts can cut your system’s efficiency by 30% and cost you hundreds of dollars a year in wasted energy.
If you’re replacing ducts in attic spaces, we also address ventilation and insulation issues that affect duct performance. Helotes sits where Hill Country terrain and South Texas heat collide, and attic temperatures here are brutal. Without proper insulation around your ducts, you’re losing conditioned air before it ever reaches your vents.
Most homeowners in Helotes spend between $2,000 and $5,000 for a full duct replacement, depending on home size and duct configuration. Larger homes or homes with complex layouts can run higher. The cost breaks down to about $25 to $55 per linear foot for professional installation, which includes materials, labor, insulation, and sealing.
If you’re only replacing a section of damaged ductwork instead of the whole system, costs are lower. But if your ducts are original to a 20-year-old home, or if you’ve had comfort problems for years, partial fixes usually just delay the inevitable.
We give you an upfront estimate after assessing your home. No surprises, no pressure. You’ll know exactly what you’re paying for and why it costs what it costs.
A full duct replacement in a typical Helotes home takes one to three days, depending on the size of your house and the complexity of the existing system. If we’re working in an attic during summer, we start early to avoid the worst heat, but the work still takes time to do right.
We’re not just pulling out old ducts and dropping in new ones. We’re sealing joints, insulating runs, mounting hangers, and testing airflow at every register. Rushing that process leads to leaks, poor airflow, and the same problems you’re trying to fix.
If you need your AC running during the work, we coordinate the installation so you’re not without cooling for long stretches. We’ve done this enough times to know how to keep you comfortable while we’re tearing apart your ductwork.
Yes. Properly installed and sealed ductwork can cut your cooling costs by 10% to 18%, according to industry studies. In Helotes, where your AC runs twice as much as the national average, that’s real money – often $200 to $400 a year in savings.
The savings come from eliminating leaks and improving airflow. When your ducts leak, your AC pumps expensive conditioned air into your attic or walls instead of your living space. Your system runs longer to hit the thermostat setting, which drives up your bill and wears out your equipment faster.
New ducts also improve comfort, which means you’re less likely to crank the thermostat down out of frustration. When every room cools evenly, you can set the temperature higher and still feel comfortable.
You can technically install your own ducts, but it’s not a good idea unless you have HVAC experience. Duct installation requires precise sizing calculations, proper sealing techniques, and knowledge of local building codes. Get it wrong and you’ll have the same problems you started with – or worse.
Undersized ducts restrict airflow and make your AC work harder. Oversized ducts reduce air velocity and hurt efficiency. Poor sealing leads to leaks. And improper insulation in a Helotes attic means you’re losing conditioned air to 150-degree heat.
Professional installation also comes with permits and inspections, which protect you if you ever sell your home. DIY ductwork that doesn’t meet code can kill a home sale or force expensive rework during escrow.
If your ducts are over 15 years old, have visible damage, or your home has persistent comfort problems despite a working AC, replacement is usually the better move. Repairs make sense for isolated damage – a torn flex duct run or a disconnected joint – but not for systemic issues.
Signs you need full replacement include multiple rooms with temperature problems, high energy bills that keep climbing, excessive dust around vents, and visible deterioration in attic ductwork. If your ducts were undersized from the start or poorly designed, repairs won’t fix the underlying problem.
We’ll assess your system honestly and tell you whether repair or replacement makes more sense. Sometimes a $300 repair buys you a few more years. Sometimes it’s throwing money at a system that needs to be redone. We’ll walk you through both options and let you decide.
Yes. We pull all necessary permits and schedule inspections as required by local building codes. Duct replacement in Helotes typically requires a mechanical permit, and the work has to be inspected to ensure it meets code requirements for sizing, sealing, and insulation.
Some homeowners try to skip permits to save money, but that’s a mistake. Unpermitted work can cause problems when you sell your home, void your homeowner’s insurance if something goes wrong, and leave you liable if the work doesn’t meet code.
We handle the permit process from start to finish. You don’t have to deal with the city or coordinate inspections. We make sure everything is done right and documented properly.
