A vacuum pump is a necessary tool for an HVAC technician to have in order to perform a number of tasks. These jobs include recharging an air conditioner, checking for leaks in the system, and replacing refrigerant. Vacuum pumps work by lowering the pressure inside the system to achieve a near-vacuum state, which is essential for removing moisture and non-condensable gasses that can destroy an AC or refrigeration unit. There are several things to look for in a vacuum pump, including its performance and size. The first thing to check is the motor, which is responsible for powering the pump. Single-stage motors are the most common, but two-stage motors can provide more power and operate faster. Also, look for a vacuum gauge, which indicates the state of the system. Finally, you should look for intake fittings and an easily accessible oil plug to drain the system.
