The answer to 'how to clean air duct cleaning yourself' is that you can clean your air ducts yourself, but it's important to do it safely and effectively. Start by turning off the HVAC system and removing any visible debris or dust from the duct openings. Then, use a vacuum cleaner with a long hose attachment to suction out any remaining dust and debris from inside the ducts. For a deeper clean, you can also use a duct cleaning brush or compressed air to dislodge and remove built-up grime.
However, keep in mind that air duct cleaning can be a complex and potentially hazardous task, especially if you have extensive ductwork or encounter mold or other contaminants. In these cases, it's best to call in a professional air duct cleaning service to ensure the job is done properly and safely.
