There is no standard answer for this question because duct cleaning depends on several factors, such as:
- The amount of pollution in your location
- The amount or vicinity of pollen in your location (some cities have an extremely high amount of pollen)
- Presence of pets in your home
- Do you have respiratory issues, like asthma, chronic bronchitis, cystic fibrosis, etc?
So, for example, if you or someone in your home is suffering from respiratory problems or you live in a city with a high pollen count, you should get your ducts cleaned at least once a year.
But the short answer would be “whenever the ducts get dirty”. If you suspect that your air ducts need cleaning, call us at (866) 725-2739, and our technicians will perform an inspection to determine whether your ducts have accumulated dirt.
