An Introduction to Air Ducts

Understanding Ductwork 

Even though summer is the time when home and business owners are very appreciative of their air conditioners, most don’t understand much about how the system works. Every air conditioning system is tailor-made for the home or business that it cools, and a huge part of designing an effective central air cooling system is the ductwork. Air ducts transport heated or cooled air around the home in every central air system. But, most often, ductwork is tucked away from view in an attic, behind walls, or the ceiling. This means that most homeowners don’t understand much about them. 

With summer ending and kids heading back to school, now is the perfect time to learn about air ducts in a cooling system. Understanding how long air ducts last and the signs that repairs or cleaning are needed can help homeowners better care for their HVAC systems. Here is some important information to help homeowners with their air ducts. 

How Long Does Ductwork Last? 

One of the biggest misconceptions about air ducts is how long they last. While air conditioners tend to last about 15 to 20 years, most people simply replace the air conditioner and don’t give a second thought to the air ducts. But most high-quality air ducts are only expected to last slightly longer than an air conditioner. When air ducts get too old, they can become damaged and inefficient and can harbor dust and bacteria, so it’s important that air ducts are replaced as needed. 

The material used is the most significant factor in determining the life expectancy of air ducts. Different materials age differently, so it is entirely possible that certain sections of ductwork will need replacement at different times. However, generally, they should be replaced after they are over 15 years old or when they become too damaged.  

Signs That Air Duct Repair Is Needed 

Air ducts can be the source of major inefficiencies in a cooling system. When air ducts fail and are damaged, they can waste a ton of money on monthly energy bills. Repairing ducts when needed can improve the HVAC system’s energy efficiency and lower costs. Here are some of the signs that air duct repair may be necessary: 

• Spiking utility bills
• Inadequate cooling power or airflow
• Hot and cold spots in the home
• Longer cooling cycles
• Poor indoor air quality 

How to Tell When Air Ducts Are Dirty 

Dirty air ducts have a significant impact on air quality and health. Periodic cleaning of air ducts can improve indoor air quality, reduce the negative health effects of poor indoor air quality, and help ductwork last longer. Some of the signs that the ductwork is dirty and air duct cleaning is needed are: 

• Foul odors
• Allergy symptoms
• Worsened asthma symptoms
• Excessive dust around the home and on flat surfaces
• Dust or mold and mildew accumulation on supply or return vents
