Image for 5 Signs Your Ductwork Might Be Costing You Money

What are the signs that you need a duct inspection? Many factors contribute to your home’s energy efficiency, such as the performance of your HVAC system. What many people don’t think about, however, is their ductwork. The network of pathways circulating conditioned air throughout your home plays a significant role in keeping your energy bills low and your comfort levels high. However, if your ducts are damaged, outdated, or leaky, they could cost you quite a bit.

Here are five signs that your ductwork might cost you money and what you can do about it.

Uneven Temperatures Throughout the House

You need to have a duct inspection if you have uneven temperatures in your home. Have you noticed that the temperature doesn’t seem the same across your home? Maybe one room is always colder (or warmer) than another, even when your air conditioning is running. Inconsistent temperatures typically indicate airflow issues within the system caused by blockages, leaks, or disconnected ducts. If air can’t reach specific areas effectively, it forces your HVAC system to work even harder. This will not only cause your system to degrade faster but also cause your utility bills to rise.

Rising Energy Bills Without a Clear Cause

Did you get a recent energy bill that seemed higher than it should be? If you haven’t changed your thermostat settings or habits, then there is a good chance your ductwork could be the culprit. Leaky ducts allow conditioned air to escape into crawl spaces, attics, or even within walls, which means the air isn’t going where you need it. This forces your HVAC system to work harder to reach the desired temperatures in your living areas. To fix this issue, you need a professional to seal or repair your ducts. It will stop the energy loss and save you money.

Dusty or Musty Air Indoors

Does it seem like you’re seeing more dust inside your house? Or are you noticing a musty smell when your AC comes on? You need a duct inspection. If your ductwork is damaged or not sealed well, it can pull in dirt and dust. When that happens, it may bring in other contaminants from areas that are not air-conditioned. They will then circulate them throughout your home, worsening indoor air quality. On top of that, it forces your HVAC system to work even harder to keep your home comfortable and clean.

Noisy Operation

Are you being disrupted daily by rattling, whistling, or banging from your vents? Not only is this annoying, but it’s a sign that your ductwork might be poorly fitted or loose. This is not uncommon in older ductwork. It’s also possible that your ducts could have been improperly configured or are too small. This can cause inefficiency and create turbulence that leads to energy waste.

Your Home Is More Than 10 Years Old and Has Never Had a Duct Inspection

Ductwork does not last forever. Over time, the seals degrade, insulation breaks down, and joints loosen. This is especially common in humid climates like Florida. If more than a decade has passed since you got your ducts inspected, it’s time to have a professional come in and evaluate them. They will ensure everything is clean, sealed, and optimized for efficiency.

What You Can Do

If any of these signs occur in your home, it’s time to act. Don’t wait for a significant problem to come up. At Aztil Air, we offer duct inspections and advanced sealing solutions like Aeroseal, which targets leaks from the inside out. This can quickly and effectively improve your HVAC performance and comfort.
