Signs You Need Air Duct Replacement

Our HVAC unit does a lot for us. We may not realize it, but they undergo severe wear and tear. Like everything we care about, our HVAC units also need regular maintenance and TLC. The last thing we want is our HVAC unit to stop working when we need it most, like on a scorching hot day. Has your HVAC unit been acting strange lately? Is it not performing as well as it used to? There could be a problem with the ductwork in your home.

What Is Ductwork

When we talk about ductwork, we refer to systems of pipes or ducts used to transport the air from the HVAC equipment through your home. Your ductwork is hidden away, so it may be difficult to know when something is wrong with it. However, there can be visible signs that something is deeply wrong with your ductwork. As time goes on, your ductwork may develop leaks. 30% of the energy used by your HVAC unit can be lost due to leaks in your ductwork. This puts more strain on your HVAC unit and uses more energy, costing you more monthly.

Signs That You Need Ductwork Replacement

If you want your HVAC unit to be with you for a long time, you may need to replace the ductwork. When you notice any of these signs, you should call an HVAC expert immediately. Continuous use of your HVAC unit might damage it further, costing you more at the end of the day.

Dirty Vents

There could be a filtration problem in your duct system. If you notice dust and dirt clogged up around your air vents. When your HVAC blows air, some dirt is left behind. Over time this builds up in the air vents of your HVAC system. Your HVAC unit has to work harder to overcome all this clogged-up dirt.


No HVAC unit is completely silent. It’s normal for there to be a slight noise when it’s on. However, if you notice unusual grinding or a loud metallic noise, then something is wrong.

Higher Electricity Costs

It’s normal for a little bit of air to escape through your ductwork. If your energy bill has risen significantly, too much air is being lost. This is a clear sign that your HVAC unit is working harder to make up for the lost air pressure and keep your home at a comfortable temperature.

Inconsistent Temperatures

If some rooms are cooler or warmer than other parts of your ductwork may be blocked or damaged. As soon as you notice these significant temperature differences, you should call an HVAC professional to fix this problem.

Low Air Pressure

If you stick your hand under the air vent of your HVAC units and you hardly feel any air blowing, this could be a sign of an air leak in your ductwork. Since most of the air escapes through the leaks in your ductwork, not much is released into your home.

Health Issues

Ductwork with leaks or damages can cause the air that flows through them to become contaminated. This can cause people in your home to suffer from severe allergies or respiratory problems. If you’re sneezing or coughing more than usual, contact a local professional immediately to make your home safe again.

Excess Dust

If you notice an increase in the dust in your home, your ducts may have holes or leaks, allowing debris to get in from outside and blow through the HVAC vents.

Terrible Odors

When there are uneven temperatures in your home, mold, and mildew can grow. You’ll be able to smell it in the air that blows from the veins of your HVAC units. This can also cause health problems and damage your furniture.

Replacing Air Filters More Often

Your HVAC filters should last at least two months. If it gets clogged up sooner, it could mean there is too much dirt and dust in your ductwork. This will cost you extra money to change filters more often.

Dusty HVAC Components

If the components inside your HVAC unit are dusty and dirty, it’s coming from your ductwork. This can severely strain your HVAC system and cause long-term damage. In the end, you’ll spend more money replacing it than you would have if you replaced your ductwork.

Old Ductwork

Your home could benefit from modern ductwork. If you installed your ductwork a few decades ago, it is likely damaged beyond repair. An air duct replacement is the best solution for this problem.
