How Often Should You Clean Your Air Ducts?
The National Air Duct Cleaning Association recommends having your ducts professionally cleaned at least once every three to five years.
Sometimes your air ducts will need to be cleaned more frequently if you suspect mold may be in the vents. Or if you’ve recently had a pest problem.
Ventilation systems are often the biggest culprit in poor indoor air quality.
If your HVAC has been operating for some time without attention, it could be circulating odors, dust and other contaminates.
