Your home's ductwork is the circulatory system of your HVAC system, quietly distributing conditioned air throughout every room. When ducts deteriorate, become damaged, or were poorly installed, your Lewisville home suffers from reduced comfort, higher energy bills, and compromised indoor air quality. LEX Air Conditioning has been serving Lewisville homeowners since 2004 with expert duct replacement services that restore efficiency and comfort to homes throughout Denton County.
Many Lewisville homes—particularly those built in the 1980s and 1990s—have original ductwork that's reached the end of its useful life. Leaky, crushed, or improperly sized ducts can waste 20-40% of the air your system produces, forcing your HVAC equipment to work harder and driving up utility costs. Our licensed HVAC technicians perform comprehensive duct assessments using pressure testing and visual inspections to identify problems that homeowners can't see from the outside. We use specialized equipment to measure airflow, test for leaks, and determine whether your existing ducts are properly sized for your current HVAC equipment.
The North Texas climate places unique demands on your home's ductwork. Summer temperatures regularly exceed 100 degrees, and your air conditioning system runs for months on end trying to keep your family comfortable. When your ducts leak conditioned air into your attic or crawl space—spaces that can reach 130-140 degrees in summer—your system works overtime just to maintain indoor temperatures. Winter brings its own challenges, with cold air seeping through gaps and poor insulation forcing your heating system to cycle constantly.
LEX Air specializes in complete duct replacement for Lewisville homes, using modern materials and advanced sealing techniques that meet or exceed current energy codes. Whether you're dealing with rodent damage in your attic ducts, crushed flex duct in tight crawl spaces, disconnected sections from settling foundations, or simply upgrading to a more efficient system, our team delivers professional installations backed by our satisfaction guarantee. We serve all Lewisville neighborhoods—from Castle Hills to Valley Ridge, Highland Village to Fox Meadows—with fast 20-30 minute response times from our nearby Plano headquarters at 901 Jupiter Road.
Our duct replacement process begins with a thorough assessment of your current system. We inspect accessible ductwork, measure temperatures at each vent, perform blower door tests to identify leaks, and use thermal imaging cameras to detect hidden problems. This comprehensive evaluation allows us to provide accurate pricing and honest recommendations about whether full replacement makes sense or if targeted repairs might solve your issues. We never upsell unnecessary services—our three-generation family business was built on integrity and transparency.

If your utility costs have increased significantly without explanation, leaky or inefficient ductwork may be wasting 20-40% of your conditioned air before it reaches living spaces.
Some rooms too hot while others are too cold? Crushed, disconnected, or poorly balanced ductwork prevents proper air distribution throughout your Lewisville home.
Leaky ducts pull in attic dust, insulation particles, and contaminants that circulate throughout your home. If you're dusting constantly, your ductwork may be compromised.
Disconnected sections, crushed flex duct, rust holes in metal ducts, or rodent damage in your attic are clear signs that replacement is needed to restore system performance.
Whistling, rattling, or popping sounds from vents often indicate air leaks, loose connections, or improperly sized ducts that need professional attention.

Why investing in new ductwork pays off for Lewisville homeowners.
New, properly sealed ductwork eliminates the 20-40% energy waste common in older systems. Many Lewisville homeowners see noticeable reductions in utility costs within the first month after replacement. When your system isn't pumping expensive conditioned air into your attic or crawl space, you're only paying to cool or heat the rooms where your family actually lives. Over time, the energy savings can offset a significant portion of your replacement investment.
Properly sized and balanced ductwork delivers consistent temperatures to every room. No more hot spots in summer or cold rooms in winter—just even, comfortable air throughout your home. We calculate proper duct sizing based on Manual D standards, ensuring each room receives the appropriate airflow for its size and usage. The result is balanced comfort that makes every square foot of your Lewisville home enjoyable.
New sealed ducts prevent attic dust, insulation particles, and outdoor pollutants from entering your living spaces. This is especially important for Lewisville families with allergies or respiratory concerns. Leaky return ducts are particularly problematic—they create negative pressure that pulls in contaminated air from attics, walls, and crawl spaces. Our sealed installations protect your family's health by ensuring only filtered air circulates through your home.
When your system doesn't have to work overtime compensating for duct leaks, it lasts longer. Proper ductwork reduces strain on your air conditioner and furnace, protecting your investment. HVAC equipment that cycles constantly due to inadequate airflow experiences premature wear on compressors, blower motors, and other expensive components. New ductwork helps your equipment run as designed, potentially adding years to its service life.
Modern duct design and installation techniques eliminate the whistling, rattling, and rushing air sounds that plague poorly installed systems. Enjoy peaceful comfort in your Lewisville home without the constant reminder that your HVAC system is running. Properly sized ducts with smooth airflow patterns operate whisper-quiet, and quality installation eliminates the vibration and loose connections that create annoying noises.
A professionally installed duct system is an attractive selling point for potential buyers. Energy-efficient upgrades like new ductwork can increase your home's resale value and make your property stand out in competitive North Texas real estate markets. Smart buyers recognize the value of efficient systems and appreciate not having to face expensive replacements shortly after purchase.
Honest pricing and local expertise you can trust.
Several factors influence the cost of duct replacement in Lewisville homes. Understanding these variables helps you make informed decisions about your project. Home size is the primary factor—larger homes require more ductwork materials and labor hours. A typical 1,500 square foot Lewisville home might require 100-150 linear feet of ductwork, while a 3,000 square foot home could need 250-350 linear feet or more.
Accessibility plays a significant role in pricing. Attic ducts in a home with good attic access and standing height are faster to replace than ducts in tight crawl spaces or finished areas requiring drywall removal and repair. The type of materials you choose also impacts cost—rigid metal ductwork is more expensive than flex duct but offers superior durability and efficiency. We present all options with honest pros and cons so you can make the choice that fits your budget and long-term goals.
Serving Lewisville since 2004 has taught us about the specific challenges local homes face. Many neighborhoods in Lewisville feature homes from the 1980s and 1990s when ductwork standards were less stringent. Original flex duct in these homes often deteriorates after 20-25 years, especially in hot attics where temperatures regularly exceed 130 degrees. We've also seen foundation settling issues common in North Texas clay soils that can disconnect or damage ductwork over time.
Lewisville's proximity to Lewisville Lake creates higher humidity levels than some surrounding areas, which can contribute to mold growth in poorly sealed ducts or condensation problems when cold supply ducts contact hot attic air. Our installations account for these local conditions, using appropriate insulation R-values and vapor barriers to prevent moisture issues that can plague inferior installations.
