Dust, mold, and other indoor allergens have a knack for getting trapped within your air ducts. Without cleaning them out, your indoor air quality can be seriously impacted. Many homeowners know to schedule annual maintenance appointments for their HVAC. But how often does a system’s air ducts need to be cleaned?
Air Duct Cleaning
The National Air Duct Cleaners Association (NADCA) typically recommends cleaning your ducts every three to five years.
Having a professional HVAC technician service your unit and your air ducts is the best way to keep your home healthy. This will ensure indoor allergens are completely removed, and that your ducts are operating efficiently.
If you or a family member suffers from asthma or allergies, you may want to stick to getting your ducts cleaned closer to the three-year mark.
Signs Your Ducts Need to Be Cleaned
Can’t recall the last time you got your vents cleaned? Then you’re probably thinking about scheduling an appointment to have the service completed relatively soon.
That being said, here are some of the signs that you should get your ducts cleaned:
You see dust exiting your supply registers when the air leaves the vents.
You suspect rodents or insects have infested your ductwork.
You notice mold growing in or on your ducts.
You see black debris outside your filter or vents.
You experience a stuffy nose or scratchy throat when your air is on.
The biggest sign that your ducts could benefit from cleaning is the presence of black debris. This is a sign that indoor pollutants have been recycled in your system and air supply.
Knowing this, the best time to schedule your appointment is:
When temperatures are cooler, or
If you are having a severe allergy flareup.
