Welcome to 2CarPros.
When you replaced the compressor, did you flush the system? Did you check what the high and low side pressures are?
To determine what could be the cause, we really need to know what the pressures are in the system. I am going to provide a link that shows how to evacuate and recharge the system using AC manifold gauges. Follow the link and let me know what pressures you are seeing and I will also need to know what the outside temperatutr is when checked.

Also, here is a link that explains how to replace a compressor. Read through it and see you missed anything.
