What is the first step in the MVAC service process?

Leak testing the system is the first step in the MVAC service process because it is crucial to ensure that there are no leaks in the air conditioning system before proceeding with any further repairs or maintenance. Identifying and addressing leaks at the outset helps to maintain the effectiveness of the service and prevents refrigerant loss, which can lead to poor cooling performance and contribute to environmental harm. If a leak is present, it needs to be fixed before any refrigerant is added or other service actions are taken. This proactive approach not only ensures compliance with environmental regulations but also prolongs the life of the system and enhances its operational efficiency.
