What is the recommended practice for maintaining air quality during duct installation?

Maintaining air quality during duct installation is crucial to ensure that the HVAC system operates efficiently and safely. The recommended practice of avoiding contamination from construction debris plays a significant role in this. When ducts are being installed, they can easily collect dust, dirt, and other particles from the construction environment. If these contaminants are not managed properly, they can be introduced into the air supply once the system is operational, potentially reducing indoor air quality and leading to health issues for occupants.

By focusing on preventing construction debris from entering the ductwork, technicians can help ensure that the ducts remain clean and the air that circulates through them is free from harmful particles and pollutants. This proactive approach not only protects the integrity of the HVAC system but also improves overall indoor air quality.

Other practices, such as using only metal ducts, choosing smaller duct sizes, or installing ducts after wall finishes, do not directly address the critical aspect of air quality during installation. While they may have their benefits in specific contexts, avoiding contamination during the installation process is paramount for maintaining clean air throughout the lifetime of the HVAC system.
