If the system is being completely filled, a vacuum will have to be pulled on the system. If the system just needs to be topped off then a vacuum pull is not needed.
When changing out a compressor or condenser, you should pull a vacuum for at least 30 minutes to an hour, depending on the system's size and the amount of moisture present. The goal is to achieve a vacuum level of 500 microns or lower to effectively remove moisture and air. Using a vacuum gauge can help ensure that the system is adequately evacuated. Always follow manufacturer guidelines for specific requirements.

When the rubber sheet on a bell jar is pulled down, it creates a vacuum seal between the bell jar and the surface it is placed on. This vacuum seal allows for the removal of air from within the bell jar when connected to a vacuum pump, creating a vacuum environment inside the jar.
No, compressors are designed to increase pressure by reducing volume, not create a vacuum by removing air. To create a vacuum, a dedicated vacuum pump is required which operates by removing air from a closed system.
The compressor won't turn on because there could be aÊproblem with the air conditioning system. You need to vacuum the system.Ê
Changing you own home AC compressor or the whole condensing unit is not a typical do-it-your-self project. Many municipalities require a permit to do the work and there is a licence to purchase and handle refrigerant so we can protect our atmosphere. You will also need the proper tools and equipment like a vacuum pump, gages and a torch along with the ability to silver solder. If you are comfortable with that - have at it. I suggest you have a reputable contractor check it out first. It may not be the compressor at all. Repair may be as simple as replacing a relay or cleaning contactors and the contractor should warranty any parts he installs.
Remove the freon from the system. Disconnect the compressor belt, then remove the lines. Unbolt the compressor and remove it. Install the new compressor, connect the lines and belt. Pull a system vacuum, then fill with new freon.
