I completed the installation of a new American Standard heating and cooling system, replacing the old unit. The project involved removing the outdated system and installing a modern, energy-efficient American Standard unit. I also installed new air filtration to improve indoor air quality and replaced the old air ducts with new ones to ensure optimal airflow throughout the space. The new system was carefully configured and tested to guarantee it operates efficiently and quietly. The project was completed with attention to detail and a commitment to enhancing the comfort and energy efficiency of the environment.
