Don’t Let Faulty Ducts Drain Your Comfort
Restoring healthy airflow and energy efficiency—one fix at a time
Your HVAC system is only as strong as the ducts and vents behind it. Even the most powerful heating and cooling units can underperform if the air has to fight through leaks, gaps, or damaged ductwork. Unfortunately, most duct issues stay hidden, wasting energy, reducing comfort, and even compromising air quality without obvious signs.
At L&S AIR LLC, we specialize in diagnosing and repairing duct and vent issues with precision and care. Whether you’re dealing with uneven temperatures, poor airflow, musty smells, or rising energy bills, our licensed experts know exactly where to look and how to fix the problem fast. From sealing and patching to full-section replacements, we bring your ductwork back to life and your home back to comfort.
Small Problems. Big Consequences. Don’t Let Damaged Ducts Drain Your Comfort—or Your Wallet.
You might not see your ductwork, but you’ll definitely feel it when something’s wrong. From poor airflow to skyrocketing utility bills, damaged ducts quietly sabotage your HVAC system’s performance and your everyday comfort. Here’s how those hidden issues make a big impact:
Air isn't reaching where it should—or getting there in the wrong amounts. Damaged or disconnected ducts often leave some areas too hot, others too cold, and your thermostat constantly in a losing battle.
Leaky ducts force your system to work harder for longer. You'll end up paying more to heat or cool air that never even makes it into your living space.
Your HVAC system turns on and off more frequently when airflow is disrupted. Not only is it loud and annoying—it's hard on your system and shortens its lifespan.
Leaks in the ductwork let in moisture, dust, or even attic contaminants. This can create mold risks and a muggy indoor feel, especially in South Texas climates.
Damaged ducts can pull in dirt and debris from crawlspaces or attics and spread it throughout your home. If you're dusting constantly, this could be the reason.
Instead of conditioned air flowing out, your system may be drawing in superheated air from unsealed duct sections, making your AC seem ineffective.
Poor airflow stresses your HVAC components, causing them to run longer and break down faster. A small duct issue now could mean a major repair bill later.
No Guesswork. No Shortcuts. Just Duct Repairs That Last.
At L&S AIR LLC, we believe in doing things the right way the first time. Our duct and vent repair process is built on precision, professionalism, and results you can feel. Here’s how we take your system from flawed to flawless—step by step.
We start with a detailed visual and pressure-based inspection to identify crushed sections, leaks, loose connections, and other a, issues—nothing gets overlooked.
Using advanced tools like smoke tests or thermal imaging, we locate hidden leaks, gaps, or temperature drops that aren't visible to the eye.
We walk you through exactly what's wrong, why it matters, and how we'll fix it—so there are no surprises, just transparency.
Whether it's sealing up leaks, reattaching loose joints, or reinforcing vulnerable areas, we use proven materials and techniques to restore airtight performance.
Once repairs are complete, we rebalance the system to ensure consistent airflow across every room, so you get even temperatures and reliable comfort.
We retest after every repair to confirm the fix worked. From pressure readings to thermal output, we make sure your ductwork is back in peak form.
We leave your space just as clean as we found it—no dust, no mess, just smooth airflow and total peace of mind.
Don’t gamble with your airflow—get it fixed the right way.
When it comes to ductwork, a temporary patch or DIY attempt might seem like the fastest solution, but it often leads to more problems down the line. Professional duct repair isn’t just about sealing a leak or taping over a crack. It’s about fully understanding your HVAC system, identifying underlying issues, and restoring airflow the right way using proven methods and proper tools.
At L&S AIR LLC, our licensed and insured technicians don’t just cover up the symptoms—they diagnose the cause. Whether it’s an improperly routed duct, worn insulation, or unbalanced air distribution, we address the issue at the source. That means fewer callbacks, more efficient performance, and lasting results.
Quick fixes often ignore airflow calculations, code compliance, and long-term system stress—all of which can quietly waste energy and shorten your HVAC lifespan. With us, you get precise repairs backed by expertise and experience—no shortcuts, no guesswork.
So, if your ducts are underperforming, don’t settle for “good enough.” Choose the team that does it once and does it right. Because when it comes to your comfort, second-rate isn’t an option.
