You can’t see inside your air ducts, but what’s building up in there could be affecting the air you breathe every day. Dust, allergens, pet hair, even bits of insulation or debris from past renovations—all of it can settle in your ductwork and quietly cycle through your home every time the system runs.
Dirty ducts can strain your HVAC system, lead to uneven temperatures, and cause odors or health symptoms that seem to come out of nowhere. If your home feels off lately and you can’t quite put your finger on why, your ducts might be part of the reason.
Let’s go over five of the most common clues that it’s time for a duct cleaning in Gresham, OR, and what to do next if you notice them.

Do Your Ducts Need Cleaning? Here’s How to Tell
1. Dust Buildup Around Vents and Registers
If you’re constantly dusting around the house and still finding buildup around vents and registers, it could be more than just a dusty week; it might be your ductwork. When ducts are filled with debris, dust can blow out through the vents and settle across your home.
A quick visual inspection is easy: if you see gray or black residue around vents, it’s worth having your system checked. Keeping filters changed regularly helps, but deep cleaning may be the real fix.
2. Unexplained Allergies or Respiratory Irritation
Do you or your family members experience more coughing, sneezing, or congestion when indoors? Dirty ducts can circulate allergens like pollen, pet dander, mold spores, and bacteria throughout the home.
If seasonal allergies seem to be lasting all year or symptoms get worse when the HVAC is running, it’s time to take a closer look. Clean ducts won’t cure allergies, but they can definitely reduce triggers in your home environment.
3. Musty or Stale Odors Coming from the Vents
A foul or musty smell wafting from your vents is often a sign of mold or mildew in the ductwork. Moisture can build up inside the system, especially in humid climates or if there’s a leak, creating the perfect breeding ground for unwanted odors.
If your home smells fine until the HVAC kicks on, don’t ignore it. A professional cleaning can remove the source of the smell and improve the air you breathe.
4. Uneven Airflow or Temperature Fluctuations
Noticing that one room is freezing while the next is stuffy and warm? Poor airflow is a common symptom of duct obstructions. Dust, pet hair, or construction debris inside the ducts can reduce efficiency and prevent consistent heating or cooling.
Your HVAC system might be in great shape, but if the ducts are clogged, it’s not performing as well as it should. Cleaning the ductwork helps restore proper airflow and system balance.
5. Recent Renovation or Past Pest Problem
Construction or remodeling can leave behind a surprising amount of dust and debris inside your ductwork, even if the space looks spotless. Likewise, any history of rodents or pests in the home may mean nesting material, droppings, or contaminants have made their way into the ducts.
If you’ve recently updated your home or dealt with pest control, schedule a duct inspection to make sure what’s in your walls isn’t blowing through your vents.
What to Do Next: Schedule a Professional Duct Inspection
If any of these signs sound familiar, it’s time to call in the pros. A professional duct inspection will confirm whether cleaning is needed and help prevent future issues.
Be sure to work with a reputable company that provides transparent pricing, proper equipment, and trained technicians, not someone offering a too-good-to-be-true deal.
