5 Signs You Need New Air Ducts

More than 90% of homes in the U.S. have air conditioning. In hot and humid climates like Florida, it's practically a necessity to have air conditioning. 

That said, we often take our HVAC systems for granted until something goes wrong. Strange noises and inefficient cooling are both symptoms of AC problems. 

But, they actually point to issues with your duct work and not your HVAC unit. Read on to learn how to spot the signs you need new air ducts so you can keep your home comfortable. 

1. A Surprise Spike in Energy Costs

If you live in a hot climate, you could expect as much as 27% of your energy bill to go towards air conditioning costs. But, that can fluctuate depending on the weather in your area and your temperature settings.  

That said, if you notice a sudden increase in your energy bill, that can point to a problem with your HVAC system. If your air ducts have a leak or a crack, the air conditioned air might not make it to your vents. That means your AC might not keep up with your thermostat. 

If your energy bill went up suddenly and you're not sure why, book an AC inspection with a technician.

2. The Ducts Are More Than 10 Years Old

With proper maintenance, air ducts can last for 10 or more years. Over time, it's normal for air duct materials to wear out. 

If you'd had your HVAC unit and air ducts for about 10 years, you should have them inspected. Your technician might suggest duct cleaning if they find dust or mold inside. They might also need to replace a few sections of ductwork.

3. Your HVAC System Has an Odor

If you notice musty or unusual odors while your HVAC system is running, that can point to an issue with your ducts. Mold and mildew thrive in dark and humid places, so it can be a problem if there's moisture in your ducts. 

A strange smell could also mean you have a crack or a hole in your ductwork. It's best to call in a technician to investigate. 

4. Your Ductwork Makes Strange Sounds

It's normal for your HVAC system to make a sound when it kicks on or turns off. But, banging or trembling noises aren't normal. 

Air duct sections are connected by plastic or fiberglass joints. As the joints wear out, the duct sections will make noise if they bang together when air passes through. 

It's a good idea to call a technician before your air ducts come apart. 

5. You Notice Dust Around the Vents

As air circulates through your HVAC system, the air filter removes dust and dirt. If you regularly replace the filter, you shouldn't see dust around your vents.

If you notice dust build-up, it could mean there's an issue with the ductwork. It's important to deal with this issue because dirt can make its way to the unit and damage the machinery.
