Should I Replace Ductwork When Replacing My AC?

June 28, 2024

If you’re planning to install a new AC unit, then you most certainly have a few thoughts going through your head. How can you choose the right system? Which HVAC installation company will you use?

An even more common question is, “Should I replace ductwork when replacing my AC?” We’ll cover all the details you need to know in this post.

Replacing Your Ductwork During AC Replacement Is Not Compulsory

If you’re already running the numbers and wondering if you truly need to replace your ductwork while getting a new air conditioner, pump the brakes. You don’t have to replace your ductwork when installing your new air conditioner.

Robust duct systems can last up to 30 years or more.  Air conditioners need replacing within 15 years. So, there’s a high probability that your ductwork can still serve you for another decade or more after your AC replacement.

Signs You Need to Replace Your Ductwork While Replacing Your Air Conditioner

You’ll need to include the cost of new ductwork in your calculations if any of the following applies in your situation.

Your Ductwork Is Already Too Old

Is your ductwork two or three decades old? Maybe you don’t even know when it was installed. In that case, you’ll likely need to replace it as well. Newer air conditioning systems are significantly different from older units from one or two decades ago. The ductwork requirements for both will reflect these differences.

An old, worn-out ductwork system may affect the performance and longevity of your new unit. Therefore, most HVAC technicians will recommend replacing everything at once.

Your Ductwork Is Too Big or Too Small

If you’re wondering, “Should I replace ductwork when replacing my AC?” you should ask yourself if the ductwork is the right size for the air conditioning unit you’re considering. In most cases, that’s a decision you’ll have to leave to experienced technicians who understand HVAC system sizing better than you do.

If the ductwork is the wrong size, you’ve handicapped your new air conditioner. Therefore, it’s more cost-effective to replace the ductwork instead.  

You Have Damaged or Corroded Ductwork

Even when the ductwork is still relatively new, it may have sustained some damage over the years. In that case, you may be better off replacing it while changing your air conditioning unit. Leaky or damaged ductwork could mean:

  • Mold and bacteria growth
  • Noisy AC operation
  • Cold spots instead of more even cooling
  • Higher energy bills

Your Ductwork Has Major Structural Issues

If your old ductwork was poorly designed, now is a good time to install a new system that’s the perfect fit for every part of your home.  Using poorly installed ductwork with your new AC could mean losing a significant chunk of any conditioned air.

What Is the Alternative to Ductwork Replacement?

The alternative to ductwork replacement is to clean the existing setup and fix any damages. However, repairs aren’t always cost-effective.

They were communicative and on time, explained everything that they would be doing to clean my HVAC ductwork, answered all of my questions, were honest about not being able to properly clean my dryer vent, and cleaned up after they were done.
