Why investing in new ductwork makes sense for Plano homes.
New, properly sealed ductwork eliminates the 20-40% energy waste common with old, leaky systems. Most homeowners see immediate reductions in their monthly utility bills—savings that pay for the investment over time.
Properly designed and installed ductwork distributes conditioned air evenly throughout your home, eliminating hot and cold spots. Every room reaches the temperature you set on the thermostat.
Sealed ducts prevent attic dust, insulation fibers, and outdoor pollutants from entering your air supply. This means cleaner air for your family and fewer allergens circulating through your home.
When your ductwork is efficient, your heating and cooling equipment doesn't have to work as hard. This reduces wear and tear, extending the life of your furnace, air conditioner, and air handler.
Modern, efficient ductwork is an attractive feature for potential buyers. It demonstrates proper home maintenance and reduces concerns about future HVAC expenses.
Old, damaged ducts often create whistling, rattling, or banging noises. New ductwork installed to proper specifications operates quietly and efficiently.
Transparent pricing with options to fit your budget.
The cost of duct replacement varies based on your home's size, the extent of replacement needed, and the type of materials used. At LEX Air Conditioning, we believe in upfront, honest pricing—no surprises, no hidden fees.

Understanding your options for long-lasting performance.
Flexible duct is the most common choice for residential duct replacement in Plano. This lightweight, insulated tubing is cost-effective, easy to install in tight spaces, and provides excellent thermal insulation when properly installed. We typically use R-6 or R-8 insulated flex duct for supply ducts in Texas attics. The key to flexible duct performance is proper support—sagging ducts restrict airflow and reduce efficiency. Our technicians install flexible ductwork with proper support straps every four feet to maintain smooth airflow and prevent energy loss.
Sheet metal ductwork offers the longest lifespan and best airflow characteristics. Galvanized steel ducts are extremely durable, won't sag over time, and provide smooth interior surfaces for optimal air movement. Metal ducts are ideal for main trunk lines and situations where maximum airflow and longevity are priorities. We wrap metal ducts with insulation to prevent condensation and improve energy efficiency. While metal ductwork costs more upfront than flexible options, many homeowners choose it for its superior performance and decades-long lifespan.
Ductboard consists of rigid fiberglass insulation panels formed into rectangular ducts. This material provides built-in insulation and is often used for return air systems. Ductboard is quieter than metal and provides good thermal performance. However, it's less durable than metal and can be damaged by moisture. We recommend ductboard for return air plenums and in climate-controlled spaces, but typically avoid it in unconditioned attics where Texas heat and humidity can cause deterioration over time.
For most Plano homes, we recommend a combination approach: insulated flexible duct (R-8) for supply branches, sheet metal main trunks with external insulation, and either ductboard or metal for return air systems. This balanced approach provides excellent performance, durability, and value. During your consultation, we'll assess your specific situation and recommend the best materials for your home's layout, HVAC system, and budget. Every home is different, and we tailor our recommendations to your unique needs.
Issues we frequently discover during inspections.
One of the most common problems we find in Plano attics is disconnected ductwork. Temperature fluctuations, poor installation, and age can cause duct connections to separate. When supply ducts disconnect, conditioned air pours directly into your attic instead of reaching your rooms. This wastes tremendous energy and makes your HVAC system work much harder to maintain comfort. We've seen cases where 30-40% of a home's conditioned air was being lost to disconnected ducts.
Many older Plano homes have ductwork with insufficient insulation—or insulation that has deteriorated over time. Texas attics regularly reach 140-150°F in summer. Without proper insulation (R-6 minimum, R-8 preferred), your cool air heats up significantly before reaching your rooms. Similarly, in winter, warm air loses heat to the cold attic. Proper duct insulation is essential for energy efficiency in our climate. When we replace ductwork, we ensure every section meets or exceeds current insulation standards.
Improperly sized ductwork is surprisingly common, especially in older homes or homes where HVAC systems have been replaced without redesigning the duct system. Undersized ducts restrict airflow, causing some rooms to be uncomfortable while making your system work harder. Oversized ducts reduce air velocity, allowing more heat transfer and potentially causing uncomfortable temperature swings. Professional duct design using Manual D calculations ensures your new ductwork is properly sized for your specific HVAC equipment and home layout.
Even ducts that appear intact often have significant air leakage at connections and joints. Studies show that typical residential duct systems lose 20-40% of conditioned air through leaks. Modern duct replacement addresses this with proper sealing methods: mastic sealant on all joints, sealed boot connections at registers, and properly installed duct collars. We test for leakage after installation to verify your new duct system is truly efficient.

How to protect your investment and maximize efficiency.
The single most important thing you can do for your new duct system is change your air filter regularly. A clogged filter restricts airflow, forcing your HVAC system to work harder and potentially damaging your new ductwork through excessive static pressure. We recommend checking your filter monthly and changing it at least every 90 days—more often if you have pets, allergies, or during heavy-use seasons. Quality pleated filters provide better filtration without restricting airflow, protecting both your equipment and your new ducts.
Schedule professional HVAC maintenance at least once per year. During maintenance visits, our technicians inspect your ductwork, check for any developing issues, clean your system components, and ensure optimal performance. Regular maintenance catches small problems before they become expensive repairs and helps your new duct system last for decades. We offer maintenance plans that include priority service, discounts on repairs, and comprehensive system inspections to protect your investment.
After duct replacement, you should notice improved comfort and lower energy bills. Monitor your utility bills to track energy savings. If you notice any rooms becoming uncomfortable again, unusual noises, or increased dust, contact us promptly. Early detection prevents minor issues from becoming major problems. Your new duct system should provide consistent, efficient performance for 15-20+ years with proper care.
After severe storms or extreme weather events, consider having your attic inspected. While your new ductwork is robust, severe weather can occasionally cause unexpected damage. A quick inspection provides peace of mind and catches any issues immediately. If you notice any water stains on your ceiling or unusual HVAC performance after a storm, contact us right away.
