When you turn on the heat or air conditioner in your Stafford, Texas, home, forced air works its way through your ductwork before it flows into each room. However, dust, debris, and other contaminants come along for the ride. Fortunately, a thorough duct cleaning can eliminate poor air quality while delivering improved HVAC efficiency. If you’re not sure when to get your ducts cleaned, here are a few telltale signs to know when it’s time.


If you’ve noticed insects in your ductwork or can hear rodents scurrying through, it’s time for a duct cleaning. The droppings from both of these critters is a source of harmful bacteria that can waft into your home if not disposed of properly. Once the ducts are clean, it’s important to eliminate any infestations and block the places where animals can get into the ducts.

Excessive Dust and Debris

Not even the best air filter can keep out dust and debris, but if it’s getting a bit excessive, your ducts are overdue for a cleaning. Generally, you should clean the ducts every two to five years, and if it’s been longer than that, you’ll notice a thin layer of dust, especially near or on air registers. If you get the ducts cleaned and there’s still a significant amount of dust, a tuneup is the best way to pinpoint the problem.

Visible Bacteria and Mold Growth

Another way to tell if you need a duct cleaning is by a visual inspection of your ducts or air registers. Mold, bacteria, and viruses thrive in your air ducts, especially when warm air and moisture is present, and they spread rapidly when your HVAC system kicks into action. If you notice any of this growth, don’t wait too long before a duct cleaning.
