Signs of Clogged Air Ducts to Watch For

If you’ve been sneezing more often indoors, noticed strange smells when the AC kicks on, or seen your energy bills creep higher—your air ducts might be to blame. Understanding the signs of clogged air ducts can help you act before minor issues become costly repairs.
In Las Vegas, where dust, pollen, and desert debris are a constant battle, clean air ducts are essential to a healthy and efficient home. Here’s what to look out for—and how Cool Breeze NV LLC can help.
1. Excess Dust Around Vents and Surfaces
If your furniture seems dusty within days of cleaning, it’s not just the dry desert air. Dust buildup around your air vents is one of the most obvious signs of clogged air ducts. Dirty ducts push dust back into your home with every heating or cooling cycle.
🧼 Tip: Wipe down the area around your vents. If dust accumulates quickly, it's time for AC vent cleaning.
2. Rising Allergy or Asthma Symptoms
Clogged ducts can harbor allergens like pollen, pet dander, mold spores, and dust mites. If you or your family members are experiencing frequent coughing, sneezing, or itchy eyes indoors, it may be due to poor air quality caused by dirty ducts.
🩺 According to the EPA, air ducts should be cleaned every 3–5 years—or more frequently in areas with high dust and pollution levels like Las Vegas.
3. Musty or Moldy Odors When the AC Is Running
A strong, musty smell when your HVAC system is on could mean mold or mildew inside the ductwork. Las Vegas’s hot summers and occasional HVAC condensation create the perfect environment for microbial growth.

4. Uneven Airflow in Different Rooms
Do some rooms feel like saunas while others are freezing? Uneven airflow can indicate blockages or debris buildup in specific ducts, making it harder for air to reach certain parts of your home.
📉 A clogged duct forces your HVAC system to work harder, decreasing efficiency and increasing wear and tear on your equipment.
5. Unusual Noises in the Ducts
If your HVAC system is making strange whistling, banging, or rattling sounds, it could be due to airflow being restricted by debris, insulation particles, or even small objects lodged in the ducts.
🎧 These noises are often overlooked but are clear signals your ductwork needs professional attention.
6. High Energy Bills With No Explanation
When ducts are clogged, your system has to push harder to maintain your desired temperature—using more energy and increasing your monthly utility bills. If your usage hasn’t changed but your bill has, blocked ductwork could be the culprit.
💸 EnergyStar.gov reports that leaky or dirty ducts can reduce HVAC efficiency by up to 20%.
7. Signs of Rodents or Insects
If you hear scratching in the vents, notice droppings, or smell foul odors, you might be dealing with pests nesting in your ductwork. These infestations can lead to dangerous contamination and restricted airflow.
🛑 After a pest issue, professional duct cleaning is a must to remove allergens and bacteria.
8. Dryer Takes Too Long to Dry Clothes
While technically not part of your HVAC system, your dryer vent can also become clogged—especially in homes that haven't cleaned it in over a year. This poses a fire hazard and impacts energy use.

9. You Can’t Remember the Last Time They Were Cleaned
If it’s been 3–5 years (or longer!) since your last duct cleaning, you’re overdue. The desert climate of Nevada makes frequent cleanings more important than in other regions.
