Is air duct cleaning worth it?

There are a few instances when cleaning your air duct is largely worth it. For example, according to the Environment Protection Agency, you may want to clean your ducts if:

• You notice visible mold growth
• There are rodents or insects inside of them 
• The ducts are severely clogged with dust and debris

You should also consider examining your heating and cooling system (HVAC) to ensure there aren’t any issues.

The National Air Duct Cleaners Association (NADCA) recommends getting your air ducts cleaned every three to five years, or every two to three years in regions where homeowners use their air conditioning and heater for many months of the year, while the EPA suggests homeowners have duct cleaning done as needed.
