Final answer:
An effective air conditioning system installation begins with a proper assessment of the building requirements, which is essential for optimal and efficient performance.
Step-by-step explanation:
An efficient and trouble-free air conditioning system installation is more likely if the installation starts with a proper assessment of the building requirements. The correct answer to the question is option 1. Assessing a building's requirements involves analyzing various factors such as building layout, room sizes, the direction the building faces, and potential heat-generating appliances, which can impact the performance of the installed air conditioning system. Consulting experts and using the appropriate technology can mitigate negative consequences such as environmental damage, excessive energy use, and noise issues. For instance, the introduction of harmful gasses used in early air conditioning systems led to ozone layer damage, but advancements in technology have allowed for the development of more eco-friendly alternatives. Therefore, starting with an informed and calculated approach ensures the air conditioning system operates optimally and efficiently.
