The answer to 'which is better air duct or' is that both air ducts and professional cleaning have their advantages, and the best choice depends on your specific situation and needs. Air ducts are essential for distributing heated or cooled air throughout your home, but they can accumulate dust, debris, and even mold over time. Professional duct cleaning can improve air quality, increase HVAC efficiency, and extend the life of your system.
On the other hand, regular maintenance and cleaning of your air ducts may not be necessary for all homes. If you don't have any noticeable issues with air quality or HVAC performance, a professional cleaning may not be required. However, if you have concerns about indoor air quality, allergies, or your HVAC system's efficiency, then a professional duct cleaning service can be a worthwhile investment.
