You’ll notice the difference in your first electric bill. Properly installed ductwork stops conditioned air from escaping into your attic or crawlspace, which means your system isn’t running overtime to keep up. The Department of Energy puts it plainly: leaky ducts can tank your HVAC efficiency by 20% or more.
But it’s not just about the money. When we install or replace your ductwork, rooms that used to feel stuffy finally cool down. Hot spots disappear. Your system stops cycling on and off constantly because it’s actually able to do its job without fighting poor airflow.
And if anyone in your home deals with allergies or asthma, this matters even more. Old, leaky ducts pull in dust, insulation fibers, and humidity that breeds mold. New ductwork means cleaner air moving through your home, not contaminated air recycling through gaps and tears you can’t even see.
In Elmendorf, TX, where summer heat regularly pushes past 95 degrees and humidity makes everything worse, your ductwork isn’t optional. It’s the backbone of your comfort. When it’s done right, your home stays comfortable without the constant repair calls or the dread of opening your electric bill.
We’ve been handling HVAC work across San Antonio and surrounding areas like Elmendorf, TX for over 20 years. We’re veteran-owned, which means we show up on time, do what we say we’re going to do, and don’t cut corners to save five minutes.
Elmendorf homeowners know what it’s like to deal with aging HVAC systems. Most homes here were built in the mid-90s, and if your ductwork hasn’t been updated since then, you’re likely dealing with undersized ducts, poor sealing, or damage from decades of Texas heat and humidity. We’ve seen it all, and we know how to fix it right the first time.
We’re not a rotating crew of subcontractors. Our certified technicians are licensed, insured, and trained to handle modern high-efficiency systems that meet current building codes. You’ll get transparent pricing before any work starts, no surprise fees on the invoice, and a team that treats your home the way we’d treat our own.
We start with an honest assessment. That means inspecting your current ductwork, measuring airflow, checking for leaks, and calculating whether your ducts are properly sized for your system. A lot of homes in North Texas have undersized ductwork, and no amount of sealing will fix that. We’ll tell you what actually needs to be done, not what makes us the most money.
If you need new ductwork, we map out the layout based on your home’s size, your system’s capacity, and how air actually moves through your space. We’re not just connecting metal tubes. We’re designing a system that balances airflow so every room gets the cooling or heating it needs without overworking your HVAC unit.
Installation means pulling out old, damaged ducts if you’re replacing them, then running new ductwork through your attic or crawlspace with proper insulation and sealing at every joint. We use mastic sealant or metal-backed tape, not the cheap stuff that peels off in a year. Every connection is checked for leaks using pressure testing, so you’re not losing air before it even reaches your vents.
Once everything’s installed, we test the system. We check static pressure, airflow at each vent, and make sure your HVAC unit is running efficiently with the new ductwork. You’ll know it’s done right because your home will feel different immediately.
Ready to get started?
When we install or replace your ductwork, you’re getting a system designed specifically for your home and your HVAC unit. That includes properly sized ducts that match your system’s airflow requirements, insulated ductwork that prevents energy loss in your attic, and sealed connections that stop air from leaking into spaces it doesn’t belong.
In Elmendorf, TX, attic temperatures can hit 150 degrees in the summer. If your ducts aren’t insulated properly, you’re cooling the air just to lose it to the heat before it reaches your rooms. We make sure every section of ductwork in unconditioned spaces is wrapped and sealed to keep your conditioned air where it belongs.
You’ll also get ductwork that’s built to handle Texas humidity. Metal ducts can corrode over time when moisture condenses on cooler surfaces, and flexible ducts can sag or tear if they’re not supported correctly. We install durable materials with proper support and slope to prevent water buildup and extend the life of your system.
And because we’re licensed and insured, the work comes with protection. If something goes wrong, you’re covered. If the installation doesn’t meet code, we fix it. You’re not taking a gamble on someone who watched a YouTube video and bought a van.
Ductwork replacement in Elmendorf, TX typically runs between $1,400 and $5,600 depending on your home’s size, the type of ducts you need, and how accessible your attic or crawlspace is. Most homeowners end up in the $3,000 to $4,000 range for a full replacement in an average-sized home.
The price breaks down to about $25 to $55 per linear foot, which includes removing old ductwork, installing new ducts, insulating them properly, and sealing every connection. If your home has a complex layout or needs custom fabrication, that can push costs higher. If you’re just replacing a section of damaged ductwork instead of the whole system, you’re looking at the lower end of that range.
Timing matters too. If you schedule the work in spring or fall when demand is lower, you’ll often get better pricing and faster turnaround than if you wait until peak summer when everyone’s AC is failing. We’ll give you a transparent quote before any work starts so you know exactly what you’re paying for.
If your ducts have a few small leaks or disconnected sections, repair usually makes sense. But if you’re dealing with widespread damage, undersized ductwork, or ducts that are 20+ years old, replacement is the smarter move.
Here’s what we look for: visible holes, tears, or rust on metal ducts; flexible ducts that are sagging, crushed, or torn; disconnected sections where air is blowing into your attic instead of your rooms; and ductwork that’s too small for your current HVAC system. If more than 30% of your ductwork has issues, replacement typically costs less in the long run than patching together a failing system.
Age is another factor. Homes in Elmendorf built in the 90s often have original ductwork that was never sized correctly or has deteriorated from decades of heat and humidity. If your energy bills keep climbing, your home has uneven temperatures, or your HVAC system is constantly running, your ducts are likely the problem. We’ll inspect the system and give you an honest assessment of whether repair or replacement makes more sense for your situation.
You can, but you shouldn’t. Ductwork installation isn’t just about connecting tubes. It requires calculating airflow, sizing ducts to match your HVAC system’s capacity, sealing connections properly, and ensuring the system meets building codes. Get any of that wrong and you’ll end up with higher energy bills, uneven temperatures, and an HVAC system that wears out faster.
Undersized ducts create too much static pressure, which forces your system to work harder and can damage the blower motor. Oversized ducts reduce air velocity, which means poor airflow and humidity problems. Improperly sealed connections leak conditioned air into your attic, wasting energy and money. And if the installation doesn’t meet code, you could have issues when you sell your home or file an insurance claim.
Professional installation also comes with warranties on both parts and labor. If something goes wrong with DIY ductwork, you’re paying to fix it yourself. If something goes wrong with our installation, we handle it. For most homeowners, the cost of professional installation is worth the peace of mind and the guarantee that it’s done right the first time.
Most ductwork installations take one to three days depending on the size of your home and the complexity of the job. A straightforward replacement in a single-story home with easy attic access usually wraps up in a day or two. Larger homes, two-story layouts, or difficult access points can push the timeline to three days or more.
The process involves removing old ductwork if you’re replacing it, fabricating and installing new ducts, insulating everything properly, sealing all connections, and testing the system to make sure airflow is balanced and there are no leaks. We’re not rushing through it just to move on to the next job. Every connection matters, and we take the time to do it right.
Weather can affect the timeline too. If we’re working in your attic during a Texas summer, we have to take breaks to avoid heat exhaustion, which can extend the job slightly. Spring and fall installations tend to move faster because conditions are more manageable. We’ll give you a realistic timeline upfront and keep you updated if anything changes.
For most homes in Elmendorf, TX, insulated flexible ductwork or rigid metal ducts with external insulation work best. Flexible ducts are easier to install in tight attic spaces and cost less, but they need to be supported properly to prevent sagging. Metal ducts are more durable and handle high static pressure better, but they cost more and take longer to install.
Texas heat and humidity are tough on ductwork. Flexible ducts can deteriorate faster if they’re exposed to extreme attic temperatures without proper insulation. Metal ducts can corrode over time if moisture condenses on the surface and isn’t managed correctly. That’s why insulation matters so much here. Properly insulated ducts prevent energy loss and reduce the risk of condensation that leads to mold and rust.
We’ll recommend the best option based on your home’s layout, your HVAC system, and your budget. In most cases, a combination works well: rigid metal ducts for main trunk lines where airflow and durability matter most, and insulated flexible ducts for branch lines running to individual rooms. The goal is a system that lasts, performs efficiently, and handles the demands of Texas weather without falling apart in five years.
Yes, if your current ductwork is leaking, undersized, or poorly insulated. The Department of Energy estimates that leaky ducts can reduce HVAC efficiency by 20 to 30%, which means you’re paying to cool or heat air that never makes it to your living space. Sealing those leaks and installing properly sized, insulated ductwork puts that efficiency back.
Most homeowners notice a difference in their first bill after installation. Your system won’t have to run as long to reach the temperature you set because the air is actually getting where it needs to go. Rooms that used to stay warm will cool down faster, and your HVAC unit won’t be cycling on and off constantly trying to keep up with demand it can’t meet.
The savings add up over time. If you’re currently losing 20% of your efficiency to bad ductwork, fixing that could cut your cooling and heating costs by $30 to $60 a month depending on your home’s size and how much you run your system. Over a year, that’s $360 to $720 back in your pocket. New ductwork isn’t just an expense. It’s an investment that pays you back every month in lower bills and fewer repair calls.
