A/C blowing hot air

Good afternoon,

Can you see the compressor engage when you turn the A/C on?

Do you have a set of gauges to give me the high and low side Freon pressures both with the engine off and with it running? I need to verify this first to be sure the system is working.

It could also be a blend door but we need to verify the Freon side first.
