When Is It Time to Replace Your Ductwork?

Ducts can last up to 15-25 years, but by the 10- to 15-year mark, they often start to show signs of wear. Louisiana’s humidity and heat can speed up deterioration, leading to cracks, rust, or sagging flexible ducts.

You may need duct replacement if you notice:

  • Uneven temperatures between rooms
  • Constant dust or musty odors in your home
  • High utility bills despite normal HVAC use
  • Weak or inconsistent airflow
  • Visible damage, kinks, or disconnected sections in the attic or crawl space
  • Ductwork older than 15 years

If your ducts have extensive leaks, mold growth, or poor insulation, replacing them is often more cost-effective than frequent repairs.

Why Duct Replacement Makes a Difference

Replacing aging or inefficient ducts offers several benefits beyond just fixing comfort issues. Professionally designed and sealed ductwork can:

  • Improve energy efficiency: Prevent air loss and help your HVAC system run less often.
  • Enhance indoor air quality: Eliminate dust, allergens, and debris that collect in old ducts.
  • Ensure even comfort: Properly sized and routed ducts deliver consistent airflow throughout the home.
  • Reduce HVAC wear: Balanced airflow lowers strain on your system, helping it last longer.
  • Quiet operation: Modern duct systems minimize vibration and rattling for a quieter home.

If you’ve been scheduling frequent duct repairs, upgrading to a new system can save you money long-term and create a more comfortable living space.

Our Duct Replacement Process

At All In Heating & Air, we make the duct replacement process straightforward and stress-free. Every home is different, which is why our technicians take the time to assess your system’s needs before recommending a solution.

Here’s what you can expect:

  1. Comprehensive Inspection: We begin by examining your existing ducts for leaks, insulation quality, and airflow issues. This helps us determine whether you need partial or full duct replacement.
  2. Custom Duct Design: Using precise measurements, we design a duct system that matches your home’s size, layout, and HVAC capacity. Proper sizing prevents airflow problems and wasted energy.
  3. Professional Installation: Our team removes damaged or outdated ducts and installs new ones with tight seals and proper insulation. We use high-quality materials built to handle Slidell’s humid climate.
  4. Airflow Testing: Once installed, we test the system to ensure balanced airflow, efficient performance, and quiet operation throughout your home.
  5. Final Walkthrough: Before we leave, we review our work with you, explain what was replaced, and provide maintenance recommendations to keep your ducts in excellent condition.

Repair or Replace HVAC Ducts?

Homeowners often ask whether duct repair is enough or if full replacement is necessary. The answer depends on the condition of your current ductwork.

You may only need duct repair if:

  • Leaks are limited to a few joints or connections.
  • The duct layout is sound, but certain sections are loose or disconnected.

Replacement is recommended when:

  • Ducts are corroded, moldy, or severely crushed.
  • There are multiple leaks throughout the system.
  • The design restricts airflow or causes uneven heating and cooling.

At All In Heating & Air, we’ll always recommend the most cost-effective option for your home. Our goal is to help you get long-term comfort and value from your HVAC system.

Frequently Asked Questions

How long does duct replacement take?

Most duct replacement projects take one to two days, depending on your home’s layout and system size. Larger or more complex systems may take longer if sections are difficult to access. Our team provides an accurate timeline before work begins.

Can I replace only part of my duct system?

Yes. If only a few sections are damaged or undersized, partial duct replacement may be the best solution. Our technicians will assess your system to determine whether a targeted repair or full replacement makes the most sense for your comfort and budget.

Will new ductwork improve my air quality?

Absolutely. Old or leaking ducts can pull dust, allergens, and contaminants from attics or crawl spaces into your airflow. Replacing damaged ductwork helps eliminate these pollutants, keeping your home’s air cleaner and healthier.
