When Should Ductwork Be Replaced?

An Air Duct Being Replaced

While you may have a great heat pump or furnace in your home or business, it won't do you much good unless you have ductwork that is in excellent condition. Since the ductwork transports warm or cool air from room to room, having ductwork that is sagging, coming apart, or rusted and filled with holes can greatly impact your HVAC system's ability to perform as well as it should. If you've got ductwork that may have you wondering if it needs to be replaced, we've got the facts you should keep in mind when making your decision.

How Do I Know if My Air Ducts Need to be Replaced?

When you have air ductwork that you think needs to be replaced, there are some things you can look for that may confirm your suspicions. The most important is if you notice warm or cool air does not seem to be making its way around your home or business as well as it has in years past. Should this be happening, it could indicate your ductwork has come apart in some spots, leading to air leaks.


You may also want to consider having your air ducts replaced if they are getting on up there in age. In fact, if you have ductwork that is at least 15 years old, it may need to be repaired or replaced. For most ductwork, 20-25 years is a typical lifespan before parts of it or all of it will need to be replaced in your home or business.


If you are examining your ductwork and notice some rusted areas, especially where one section connects to another, this is usually a sign condensation has been forming on the metal during the summer, when the air conditioning system has been operating. Once the rust begins to eat holes in the metal, connections can break down and cause air leaks. Along with this, sections may start to sag and buckle, which will block airflow.

Poor Design and Rodent Damage

In some homes and businesses, especially those that are older, ductwork systems may have been poorly designed from the outset. If a system has numerous twists and turns, is not properly insulated, or has been prone to rodent damage over the years, this can lead to a variety of problems that have you needing a new ductwork system.

Is Replacing Ductwork Expensive?

When replacing ductwork in a home or business, we at Pro-Duct Cleaners take several factors into account before giving an estimate to our customers. The most important factor is the size of the home or business since this will determine how many linear feet of ductwork will be needed. Another important part is the complexity of the system itself, since older ductwork systems that may have been poorly designed may require rerouting to make them more efficient and practical. While we are always happy to give you a free estimate prior to beginning any job, research has shown the average cost to replace ductwork in a home or business typically ranges from just over $1,000 to perhaps $5,000 or more.

How Long Does it Take to Install Ductwork?

Just as it is when determining the cost of replacing ductwork, numerous factors are involved in how long it takes to install ductwork inside your home or business. For example, if you don't need the entire ductwork system replaced, the job may take no more than one day to complete. However, if an entirely new system needs to be installed, we recommend you allow two or three days for the project to be finished. Since we know you have a busy life to live each day, we always work with our customers to ensure we can install ductwork with as little disruption to their schedules as possible.

How Will I Benefit from New Ductwork?

Once our team here at Pro-Duct Cleaners has installed new ductwork at your home or business, you'll benefit in many ways. First, your energy bill should start to go down, since your HVAC system will be operating very efficiently. Next, you and everyone else in your home or business should be much more comfortable, since warm or cool air is flowing as it should from room to room. Last but not least, getting rid of those ductwork leaks means mold, dust, pollen, bacteria, and other allergens won't be able to contaminate the surrounding air you are breathing, meaning you won't have to worry about continuously sneezing, sniffling, and feeling less than your best.
