Your home's ductwork is the circulatory system of your HVAC. When ducts are old, damaged, or poorly designed, your comfort suffers—and so does your wallet. Arlington homeowners lose hundreds of dollars every year to leaky, inefficient ductwork that wastes conditioned air, drives up energy bills, and creates uneven temperatures throughout the home.
LEX Air Conditioning has been replacing ductwork in Arlington since 2004. We've seen it all: ducts crushed by attic storage, systems disconnected during remodels, decades-old flex duct that's deteriorated beyond repair, and improperly sized systems that never worked right from day one. Our duct replacement service isn't just about swapping old ducts for new ones—it's about designing a properly sized, sealed, and insulated system that delivers comfort to every room in your home.
Located just a short drive away in Plano at 901 Jupiter Rd, we provide Arlington with 25-35 minute response times for emergency repairs and same-day or next-day appointments for duct replacement consultations.

We install high-quality materials, seal every connection with mastic, and insulate to R-8 standards to maximize efficiency. When we're done, you'll notice the difference immediately: better airflow, more consistent temperatures, lower energy bills, and cleaner indoor air.

If your electric bills keep climbing despite consistent usage, leaky or uninsulated ducts are likely wasting conditioned air. Duct replacement typically pays for itself in 5-7 years through energy savings.
Hot and cold spots throughout your home indicate poor airflow, improperly sized ducts, or disconnected ductwork. Replacement ensures balanced comfort in every room.
Leaky ducts pull in attic dust, insulation particles, and allergens, distributing them throughout your home. New, sealed ducts dramatically improve indoor air quality.
Crushed, torn, or disconnected ductwork in your attic or crawlspace requires immediate replacement. Even small gaps can waste 20-30% of your conditioned air.
Older flex duct deteriorates over time, developing cracks, gaps, and insulation breakdown. If your ducts are 15+ years old, replacement is likely more cost-effective than ongoing repairs.
Mold growth inside ductwork poses serious health risks. If you smell musty odors when your HVAC runs, or see visible mold, replacement with properly sealed ducts is essential.
Professional installation from start to finish.
We begin with a thorough inspection of your existing ductwork, using thermal imaging and blower door testing to identify all leaks, disconnections, and efficiency issues. We measure airflow at each register and document problem areas with photos.
Using ACCA Manual D calculations, we design a properly sized duct system matched to your home's square footage, insulation, and HVAC capacity. This ensures balanced airflow and eliminates hot/cold spots.
Before any work begins, we provide a detailed written estimate covering all labor, materials, and disposal fees. No hidden costs, no surprises—just honest pricing from a family-owned business.
Our licensed technicians remove old ductwork, install new properly sized ducts, and seal every connection with mastic (not tape). We insulate to R-8 standards and secure all ducts to prevent sagging or disconnection.
After installation, we test airflow at every register, verify proper static pressure, and conduct a final blower door test to confirm the system is sealed and performing as designed.
All duct replacement work is backed by our satisfaction guarantee and manufacturer warranties on materials. We follow up after installation to ensure you're experiencing the comfort and efficiency improvements you deserve.
Transparent pricing with no hidden fees.
Duct replacement costs vary based on your home's size, attic accessibility, and ductwork complexity. Most Arlington homes fall into these ranges:

Yes. Homes with leaky or poorly insulated ductwork lose 20-40% of conditioned air. Professional duct replacement with properly sealed and insulated ducts typically reduces energy bills by 15-30%. Most homeowners see the investment pay for itself in 5-7 years through energy savings alone.
In most cases, yes. We access ductwork through your attic or crawlspace, avoiding interior walls and ceilings. Occasionally, register openings need minor adjustments for proper sizing, but we minimize any cosmetic impact and repair all access points professionally.
It depends on the condition of your existing ducts. We can often replace damaged sections while preserving functional ductwork. However, if your ducts are 15+ years old, have widespread leaks, or are improperly sized, full replacement is usually more cost-effective long-term.
We install both flexible and metal ductwork, depending on your home's needs. Flex duct is common for residential applications and offers excellent insulation when installed properly. Metal duct is more durable and often used for main trunk lines. We'll recommend the best option during your consultation.
