Your home's ductwork is the circulatory system of your HVAC. When ducts are damaged, disconnected, or deteriorating, your comfort suffers—and so does your energy bill. LEX Air Conditioning provides complete duct replacement services for Flower Mound homeowners, replacing old, leaky ductwork with properly sealed, energy-efficient systems that improve airflow, air quality, and system performance.
Operating from our Plano headquarters since 2004, we've replaced thousands of duct systems throughout Flower Mound and the surrounding communities. Our NATE-certified technicians use manual load calculations to design properly sized duct systems, seal all connections with mastic (not just tape), and insulate ducts to minimize heat loss. Whether your ducts are damaged by age, pests, or poor installation, we'll assess your system and provide honest recommendations backed by upfront pricing.
Flower Mound's mix of newer construction and established homes means we see a wide range of ductwork conditions—from undersized flexible duct in attics to deteriorating duct board and crushed ducts in tight crawlspaces. Our team is equipped to handle any duct replacement project, large or small, and we work efficiently to minimize disruption to your home. Most single-story duct replacements can be completed in one to two days, while two-story homes may require additional time depending on access and system complexity.

Leaky or poorly insulated ducts can waste 20-30% of your cooling and heating energy, driving up utility costs every month.
Hot or cold spots throughout your home often indicate disconnected ducts, crushed flex duct, or undersized ductwork.
Leaky ducts pull dust, insulation fibers, and attic air into your living spaces, reducing air quality and increasing allergens.
Torn flex duct, rusted metal ducts, crushed sections, or disconnected joints all compromise system performance and should be replaced.
Mold or mildew smells coming from vents indicate moisture intrusion in ductwork—often from condensation on poorly insulated ducts.
Whistling, rattling, or popping sounds often mean undersized ducts, loose connections, or crimped flex duct restricting airflow.
A proven approach that ensures quality results and lasting performance.
We perform a complete duct system inspection, checking for leaks, damage, improper sizing, and poor installation. We use airflow measurements and visual inspection to identify all problem areas.
We perform Manual J and Manual D calculations to properly size your duct system, ensuring balanced airflow to every room and quiet, efficient operation.
We carefully remove old ducts, dispose of debris, and prepare the installation area. We protect your home with floor coverings and minimize dust during removal.
We install new, properly sized ductwork using high-quality materials. All connections are sealed with mastic (not just tape), and ducts are insulated to code.
