Air Ducts: Your HVAC’s Lifeline to Efficiency

Like the relationship between your lungs and fresh air, your air ducts play an important role in the efficiency of your HVAC system. As we breathe, our lungs expand and contract, allowing oxygen to flow throughout our body. If something becomes constricted or inflamed, you can expect to have shortness of breath among other circulation issues. Similarly, if you have dirty ductwork that has never been proactively cleaned, you can expect your HVAC system to become inflamed. This can result in poor performance, high energy bills or usage, and recurrent repairs.

  • Does your HVAC system efficiency rely on clean and properly maintained air ducts? Yes, it does!
  • Can homeowners do anything to prevent build-up and system failure? Absolutely!

Read below to find out why your HVAC system deserves to have a clean space to process and create a breathable environment for your home.

Your HVAC’s Lifespan

Resources show that the average HVAC system will survive for roughly ten to twenty-five years. This appliance purchase is one of the largest that homeowners will make, so it’s imperative that you take responsible steps to take care of it.

The dexterity of your HVAC system relies on the factors of your environment. If you live in an area with higher humidity levels, you know that your HVAC will be working hard to dehumidify your air. However, if you notice a sudden change in the humidity inside your home, your air ducts might be due for cleaning. As the system pulls in air and circulates it throughout the ductwork and filters, it brings in outside irritants such as dust, debris, and pet hair. Over time, this can build up and create a tighter space for air to flow through. This will affect not only the input of your HVAC but more importantly, the output (AKA- the air you breathe!).

Hand in Hand

When you hear the words “energy” and “efficiency” a few things might come to mind, but you might not fully understand the direct correlation between your dirty air ducts and your HVAC’s efficiency levels. As the system struggles to work past the buildup of debris and other materials, it creates stress on your HVAC’s ability to heat and cool properly. This might cause the system to overheat and quit working altogether. When this happens, you might hear your AC system turn on and off frequently as it trips and stutters to keep running. According to Carter Comforts, the top three reasons for HVAC overheating lies within dirty and clogged air filters, refrigerant leaks, and dirty coils. This increase in energy usage ultimately boils down to your monthly energy bill. Some coastal states such as Hawaii see an average of a two hundred dollar bill every month!

To Repair or Replace?

As discussed above, replacing your HVAC is one of the largest appliance purchases you will have as a homeowner. When purchasing a new home, ensuring the HVAC is thoroughly inspected could save you thousands of dollars. Regardless of the HVAC system’s age, having proper maintenance done will be key to preventing issues and fixing small malfunctions before it’s too late. Just like the dust builds up on your ceiling fans, you might be able to get away with forgetting to clean your air ducts or change filters for a couple of months, or sometimes even years. However, by doing this you are introducing the buildup of debris and moisture which can cause mold growth or other bacterial implications on your health.

The numbers can be large. Depending on the size of your home, the quality of the air ducts, and the damage done to your HVAC, you might be looking at anywhere from five to eleven thousand dollars to fully replace your system. Some sources even recommend you taking out a bank loan to cover this cost… imagine what you could do if you had that extra money laying around instead of having to replace your HVAC unit!

“I don’t have five to eleven thousand dollars lying around.”

Makes sense– most people don’t! If you did, you would probably want to spend it on a trip or a loved one, not your air ducts, right? Fortunately, there are direct correlations between properly maintaining the health of your air ducts and the function of your HVAC.

For starters, make sure you are replacing your air filter on a regular basis, going no longer than every three months. Anytime you have a water leak, excess moisture, or notice your system turning on and off too frequently, you should consider scheduling a cleaning. Perhaps most important, consider having your air ducts maintained by a professional company. The National Air Duct Cleaners Association is an excellent source for knowing how to contact the right, qualified people for the job. A professional can properly clean out your ductwork and thoroughly check for anything that might be amiss, while educating you for future issues to be aware of. When your system is clean, it will require less energy to run. Not only does this lower your monthly energy bill but it will also put less strain on your HVAC system. When your air ducts are clean, your HVAC can function properly, and you can breathe worry-free!
