Takes forever for the cold air to come out?

Hello, have you checked the refrigerant pressures? If you do not have a manifold gauge set, I would not bother using the simple low-side gauges you get from the store. A manifold set can be relatively inexpensive but maybe not worth the investment depending on your use. Sometimes an evacuation & recharge A/C service will improve the performance, which is essentially an oil change for the system. It sounds like to me the compressor may be having a hard time getting the lubrication it needs.

From what you described it could be low on Freon or over charged, both can cause it to not cool quickly. An A/C pressure check can help determine if it has this issue. We need to check the high and low side pressures when it first starts and then again when after it's cold.

If you can get a manifold gauge set to look at both high and low side pressures, this will help me better determine where to proceed.
