Your home's ductwork is the hidden circulatory system that delivers heated and cooled air to every room. When ducts are damaged, poorly designed, or past their prime, your comfort suffers—and so does your wallet. LEX Air Conditioning has been providing professional duct replacement services to Frisco homeowners since 2004, helping families breathe easier and save hundreds on energy bills.
Old or damaged ductwork can lose 20-40% of your heated or cooled air before it reaches your living spaces. That means your HVAC system works harder, runs longer, and costs more to operate—all while failing to keep your home comfortable. Leaky seams, crushed sections, inadequate insulation, and poor design all contribute to wasted energy, hot and cold spots, and excessive dust. If your Frisco home has ducts that are 15+ years old or show visible damage, it's time for a professional evaluation.
LEX Air specializes in complete duct system replacement for Frisco homes of all sizes. Our licensed HVAC technicians perform thorough evaluations, design custom duct layouts optimized for your home's specific needs, and install high-quality, properly sealed ductwork that delivers consistent temperatures and lasting energy savings. We handle everything from attic duct replacement to full-home redesigns, using premium materials backed by our satisfaction guarantee.

If your heating and cooling costs have increased significantly without explanation, leaky or inefficient ductwork may be wasting 20-40% of your conditioned air.
Hot and cold spots throughout your home indicate poor duct design, crushed ducts, or disconnected sections that prevent proper air distribution.
Leaky ductwork pulls dust, insulation particles, and attic contaminants into your air supply, coating your home in dust no matter how often you clean.
Crushed, disconnected, or deteriorating ducts in your attic or crawlspace are clear indicators that replacement is needed to restore system performance.
Weak airflow from vents suggests undersized ducts, blockages, or excessive leakage that prevents your HVAC system from delivering adequate comfort.
Older ductwork lacks modern sealing standards, proper insulation, and efficient design—replacement brings your home up to current efficiency standards.

Local knowledge, proven results.
Frisco's rapid growth has created unique ductwork challenges. Many homes built during the early 2000s construction boom have ductwork installed quickly, often with minimal sealing or inadequate insulation. Add extreme Texas attic temperatures—often exceeding 150°F in summer—and you have premature duct failure and massive energy waste.
LEX Air has been serving Frisco homeowners since 2004, giving us firsthand experience with the specific duct issues common in this area. We understand which neighborhoods have older ductwork nearing replacement age and how to design duct systems that handle Frisco's climate extremes while delivering consistent comfort. Our team knows local building codes, optimal insulation levels, and the best materials for Texas conditions.
Located at 901 Jupiter Rd in Plano, we provide fast response times (typically 20-30 minutes) and personalized service from technicians who live in the same communities we serve.

Most service calls in Frisco receive a 20-30 minute response time from our Plano headquarters. For emergencies, we offer 24/7 service. Complete duct replacement projects typically take 1-3 days depending on home size and system complexity.
Typical duct replacement costs range from $3,500-$8,000 for most Frisco homes (1,500-2,500 sq ft), depending on home size, duct system complexity, materials chosen, and accessibility. We provide upfront, transparent pricing with flexible financing options available with approved credit.
Properly installed and maintained ductwork can last 15-25 years, but extreme attic temperatures in Texas—often exceeding 150°F—can accelerate deterioration. Flex duct insulation breaks down, connections loosen, and sealing fails over time. If your ducts are 15+ years old, professional evaluation is recommended.
Both have advantages. Flex duct is cost-effective, easier to install in tight spaces, and works well when properly installed and supported. Rigid metal duct is more durable, provides smoother airflow, and lasts longer but costs more. Our technicians will recommend the best option based on your home's layout, budget, and performance goals.
Yes. Old, leaky ductwork can waste 20-40% of your heated or cooled air, forcing your HVAC system to work harder and run longer. Properly sealed and insulated new ductwork eliminates this waste, often reducing energy bills by 15-30% while improving comfort and indoor air quality.
Yes. LEX holds HVAC license TACLA38788C. All technicians are fully licensed, insured, and background-checked. We've been serving Frisco since 2004.
Not always. If only certain sections are damaged or undersized, partial replacement may be an option. However, if your entire system is old, poorly designed, or has widespread issues, complete replacement provides the best long-term value. Our technicians will assess your specific situation and recommend the most cost-effective solution.
Duct sealing can address minor leaks and improve efficiency if the ductwork is relatively new and in good condition. Replacement is needed when ducts are crushed, disconnected, severely deteriorated, poorly designed, undersized, or over 15-20 years old. Our technicians perform thorough inspections and provide honest recommendations based on your system's condition.
