How often is it recommended to clean the ventilation systems in a home, and what factors can affect the need for this procedure? I am interested in this question to get recommendations on how to care for the ventilation in my home and keep it clean and safe.

I would also be interested in an answer to this question. I live in a pretty polluted area and cleaning the ventilation in my house would be good for me.

Some experts say that you should have your ventilation cleaned every 2-3 years. For me this is too long, I order duct cleaning from https://comfortclean.com/ every six months or once a year. I have animals and small children in my house, so I worry about the air in my house to be clean. Clean air in the house is the key to good health around the house. In addition, I would recommend duct cleaning to avoid fire safety problems in the home.
