Old, leaky ductwork wastes energy and drives up your utility bills. LEX replaces your entire duct system with precision — new materials, proper sizing, and a sealed installation that makes your home comfortable from room to room.
Your ductwork is the circulatory system of your home. When it leaks, collapses, or ages out, your HVAC system works overtime trying to compensate — and your energy bills pay the price. LEX has been replacing ductwork in DFW homes since 2004, and our technicians know exactly what it takes to design, size, and install a duct system that performs in Texas heat.
Whether you need a full ductwork replacement, a partial replacement to fix problem zones, or a new duct system for a renovation or addition, LEX provides honest assessments, upfront pricing, and expert installation backed by a satisfaction guarantee. We service all duct types — flexible, rigid sheet metal, and insulated — and we'll recommend the best option for your home's layout and your HVAC equipment.
Comprehensive ductwork solutions for every home and every situation.
Complete removal and replacement of your entire ductwork system. Recommended for homes with ductwork over 15–20 years old, widespread damage, or systems that were improperly sized at installation.
Replace only the damaged, deteriorated, or underperforming sections of your duct system — a cost-effective solution when the rest of your ductwork is still in good condition.
Modern flexible ductwork is cost-effective, easy to route through tight spaces, and energy-efficient when properly installed. LEX ensures correct diameter sizing and secure connections at every joint.
The gold standard for durability and airflow performance. Rigid metal ducts last 30+ years, resist mold and pests, and maintain consistent airflow. Ideal for high-performance HVAC systems.
Attic ductwork in Texas summers can reach 130°F+. Properly insulated ducts prevent heat gain in unconditioned spaces, dramatically improving system efficiency and comfort throughout your home.
Improper duct sizing is one of the top causes of comfort problems and high energy bills. LEX performs Manual D load calculations to design a duct system perfectly matched to your home and HVAC equipment.
Don't ignore these warning signs — old or damaged ductwork costs you money every single month.
If your cooling and heating costs have increased year over year without a clear reason, leaky or deteriorated ductwork may be losing 20–30% of your conditioned air before it ever reaches a room.
Some rooms blazing hot while others stay comfortable? Uneven airflow is a classic sign of ductwork problems — whether that's collapsed sections, disconnected joints, or improper sizing.
Leaky duct joints pull in attic dust, fiberglass insulation particles, and debris from unconditioned spaces and distribute them through your living areas. If you're dusting constantly, your ducts may be the culprit.
Flexible duct materials degrade over time — the inner liner cracks and separates, insulation deteriorates, and joints loosen. If your home's ductwork dates to the early 2000s or before, it's likely approaching end of life.
Unusual sounds from your vents often indicate collapsed sections, disconnected duct runs, or loose metal that vibrates under pressure. These issues rarely self-correct and tend to worsen over time.
If you can see damaged, crushed, or disconnected ductwork in your attic or crawlspace — or you've noticed musty odors suggesting mold inside ducts — replacement is almost always the right call over repair.
Noticing any of these issues? Don't wait — every month with failing ductwork is a wasted utility bill.

Duct repair makes sense when damage is isolated — a disconnected section, a few leaky joints, or a small puncture. Replacement becomes the better investment when your ductwork is over 15 years old, when more than 25–30% of the system is compromised, when ductwork is improperly sized, or when you're simultaneously replacing your HVAC equipment. Our technicians will inspect your system and give you an honest recommendation — we won't push replacement when repair is all you need.
Most residential duct replacements are completed in one to two days. Larger homes, complex attic configurations, or jobs requiring duct system redesign can take up to three days. We'll give you a firm timeline in your quote so you can plan accordingly.
Significantly, yes. The EPA estimates that leaky ductwork wastes 20–30% of the energy your HVAC system produces.

Most homeowners see a full return on their investment within three to five years — and enjoy more comfortable rooms immediately.
Rigid sheet metal ductwork can last 30+ years. Flexible ductwork typically lasts 15–25 years, though Texas attic heat can shorten this.
