Your heating and cooling ductwork can become damaged which will result in energy being lost and cost you hundreds of dollars a year. If you’re seeing an increase in energy use but aren’t using additional appliances, you may have damage to your air duct system.

However, there are fixes for damaged ductwork that will help prevent more problems and save you money. In this article, you’ll learn how to know it’s time to replace your ductwork and why good air duct systems are important.

How Good Heating and Cooling Ductwork Is Necessary

Your heating and cooling ductwork is an essential part of your HVAC system. This component circulates air through the air ducts and pushes it out through your vents and throughout your home.


Two issues caused by damage in your ductwork system, such as holes, poor duct connection, and leaks, are low air pressure and higher-than-normal energy bills. It can also create issues with your health and well-being.

Mildew and mold can accumulate inside your air ducts and are then pushed through the vents to you. This can cause serious illness when these toxic particles are breathed in.

When your heating and cooling system ductwork is free from any issues you will be able to notice the benefits almost instantly. Your system will have higher air pressure, better circulation, free from dangerous materials, and the system’s lifespan will greatly increase.

How Do You Know Your Ductwork Needs To Be Replaced?

Ductwork should be replaced for various reasons. Here are some ways to know if a ductwork replacement is the right thing for your HVAC system.

Your HVAC System Makes Strange Noises

If you’re hearing noises coming from your HVAC system that are out of its normal operating sounds, it may be time for a replacement. A hole may be present in your ductwork if you hear loud noises when air begins flowing through the air ducts. Vibrating or rattling sounds can signal that there is a damaged joint.

Your Energy Bill Has Gone Up

When your HVAC system is working harder than normal or is straining to heat or cool a room it will use up more energy. This will cause your energy bill to increase. Damage to the ductwork will create this problem when there is a leak or hole in the system.

Your Home Has Hot And Cold Spots

When there is damage to your heating and cooling ductwork it can create some areas of your home to remain hotter or colder than other parts. This is the result of air leaving the air ducts before it has a chance to properly circulate through your duct system and flow into the space you are cooling down or heating up.

Dust Is Accumulating In Your Home

Damaged ductwork in your HVAC system will allow dust to enter into your home from outside through leaks and holes. If you’re noticing there seems to be a lot more dust accumulating in your home, ductwork damage may be the culprit.

You’re Smelling Mold Or Mildew

Toxic materials like mold or mildew can build up in your ductwork. This is usually the result of temperatures fluctuating and allowing condensation to collect in the ducts. It can also be caused by poorly connected and insulated ducts. These harmful materials can pose a threat to you and your family’s health.

More Pests Than Usual

Pesky creatures such as rodents, bugs, and spiders can get into your home through holes and leaks in your air ducts. Because they will be able to enter your home with ease an infestation may occur. This can cause further issues such as blockages.

Air Vents Have Built Up Dirt & Debris

If you see dirt, pet hair, lint, and dust built up around your air vents it is because the air has become dirty. Damage to your ductwork like holes and leaks will create this problem in your home.

Ductwork Is Old

Heating and cooling ductwork is designed to last about 10-15 years. But as your home gets older so does your ductwork system. If your home is older than the typical lifespan of ductwork, you should consider a replacement because it will be more vulnerable to holes and leaks forming.

How You Can Fix Your Ductwork

If you’ve decided that it’s time for a ductwork replacement and you’re ready to get it fixed, consider the next steps to remedy this problem on your own.

Clean your air ducts, seal them, and then insulate the ductwork. These few steps will allow you to fix the holes and leaks in your air duct system. An inspection done by a professional after you’ve taken care of the big problems will allow you to find any other potential problem areas.
