Your ducts are an important part of your heating and cooling units and are crucial in delivering heated or cooled air to your living space. However, over time it may become dirty, clogged with debris, and unable to perform optimally. When this happens, investing in replacing it is much needed for your HVAC units to continue working properly.
If you aren't sure if your ductwork needs to be serviced, then you are in luck, as this blog entails ten reasons why replacing old ductwork is a good idea.
But before we cover why replacing old ductwork is a good idea, let's look at what they do, how long they typically last, the cost to replace air ducts, and the common signs it is the best time to invest in the service.

What are ductworks?

Air ducts are tubes that carry heated or cooled air throughout your living space. They connect to your heating or cooling units and circulate air from vents in different rooms of your house.

How do air ducts work?

They are typically made up of metal or plastic, and they use a series of fans and other mechanical components to draw air into the tube, push it through to your home’s vents, and then exhaust it back into your heating or cooling units. They allow them to deliver clean, efficient air to every room in your house while keeping the temperature constant.

How long does ductwork last?

Ductwork may last anywhere from 10-40 years, depending on various factors, including what material they are made from and how well they are maintained. Wondering, "should ductwork be replaced after 20 years?" Generally, replacing them is a good idea if they show signs of wear and tear.

How often should you invest in replacing your ductwork?

So how often should air ducts be replaced? There is no definitive answer to how often to replace ductwork, as it depends on several factors. Some key considerations for when to replace ductwork include the age and condition, whether you have experienced any problems with leaks or airflow restrictions, and your overall HVAC usage patterns. Generally speaking, it is a good idea to invest in regular inspections and maintenance services so that you may identify any issues early on before they start causing problems.

Signs You Need to Replacing Your Ductwork

Several signs indicate the best time when to replace air ducts, and these include the following:
  • Leaks coming from the pipes
  • Loose or disconnected ducts
  • It doesn’t extend fully through the house
  • Have visible cracks and holes
  • Excess dust, mold, or moisture on your property
  • Poor air quality or strong odors in your house
If you are experiencing any of these, it is time to consider replacing them. Replacing your ducting will provide numerous benefits, so let's look at some of them now.

Benefits of Replacing Your Ductwork

Now that we know more about ducts in general, let's take a look at the top 10 reasons why replacing them may be a good idea:
1. Improved Air Quality
One of the primary benefits of replacing your ductwork is that it improves the air quality in your property. Old or damaged ones may leak and accumulate dust, pollen, and other allergens inside your living space, triggering asthma and allergy symptoms. Also, mold and mildew may grow in damp ducts, leading to poor quality.
2. Enhanced HVAC Efficiency
Another benefit of replacing your ducting is enhancing your heating and AC units' efficiency. If they are not properly sealed or insulated, it may cause your HVAC units to work harder than necessary to maintain a comfortable temperature in your house. And this will lead to higher energy bills and shortened lifespan for your HVAC.
3. Reduced Pest Infestation
Another advantage of replacing your ducting is that it helps reduce the risk of pest infestation. Pests such as rodents and insects are attracted to damp and dark places, making them an ideal environment to nest. By replacing them, you may help to deter pests from making their way into your property.
4. Reduced Energy Bills
Another benefit of replacing your ductwork is that it helps reduce your energy bills. Leaky or damaged ducts may cause your heating and cooling units to work harder than they need to, leading to higher energy bills. Investing in replacing your ductwork will help seal up any leaks and ensure that your heating and cooling operate as efficiently as possible.
5. Reduced Allergies
If you or someone in your family suffers from allergies, replacing your ductwork helps reduce their symptoms. As mentioned above, dust and other allergens may build up inside over time and circulate throughout your living space when the furnace or AC unit is turned on. You may remove these allergens from your property and reduce allergy symptoms by replacing your ducting.
6. Fewer Repairs Over Time
You may avoid costly repairs by replacing your old system with a new one. Not properly sealed or insulated may cause major problems for your HVAC units, including decreased efficiency and shortened lifespan. By investing in a new one now, you may be able to avoid expensive repairs down the road.
7. Increased Home Value
Another benefit of replacing your old system is that it could increase the value of your living space. If you plan to sell your property, potential buyers will be impressed by updated features like new ones. Energy-efficient homes are becoming increasingly popular, so updating them could make your living space more attractive to buyers looking for an eco-friendly option.
8. Improved Comfort Levels in Your Home
It could be the best time for the service if you’re constantly adjusting the thermostat to achieve a comfortable temperature in your house. Ducts that are not properly sealed or insulated causes hot or cold spots throughout your house, making it difficult to maintain a consistent temperature. Investing in a new one means enjoying a more comfortable property without constantly adjusting the thermostat.
9. Quieter Operation Of Your HVAC System
If your heating and AC units are noisy, it could be due to old or damaged ductwork. When it is not properly sealed, it allows air leaks, creating a whistling sound. Additionally, if there is any damage to the parts, it causes banging or rattling noises. You may help reduce noise levels from your HVAC by replacing old or damaged ones.

10. Better Airflow Throughout Your Home

If you’ve noticed reduced airflow from your vents, replacing old ones is a good idea. Over time, dirt and debris may build up in it, restricting airflow and making it difficult for your HVAC units to operate efficiently. In some cases, blockages in pipes also occur, preventing airflow altogether. Replacing them helps ensure that proper airflow is restored throughout your entire living space.
So for the million-dollar question, "is replacing ductwork worth it," the answer is YES. Replacing your old ones offers many benefits for you and your property, including improved comfort levels, reduced energy costs, and an increased resale value.

Generally speaking, the ductwork replacement costs may range anywhere from several hundred dollars to several thousand dollars or more, depending on the size and complexity of your house.
