When gauge readings indicate pressure after 5 minutes in a ac system after vacuum What is next?

If gauge readings indicate pressure in the AC system after holding a vacuum for 5 minutes, it suggests that there may be a leak or that moisture has entered the system. The next step is to perform a leak check using a soap solution or electronic leak detector to identify any leaks. If no leaks are found, proceed to recheck the vacuum level and ensure it meets the manufacturer's specifications before recharging the system with refrigerant.
