Question AC not providing cold air

I have a 16 years old outdoor Trane HVAC not providing cold air. I replaced both the Capacitor and the Contactor and still no cold air coming out from the vents. Any suggestions before I call the technician??? Thanks

The condenser is two parts..... the fan and the compressor. Are they both running ??

Thanks Pete, Not sure how do I know if the compressor running. The fans are spinning and air coming out of the vents in the house

You usually can't miss the sound of the compressor and it makes it's own rumble. If it's running..... the larger insulated copper refrigerant line will be ice cold.

Thanks for the response Pete. None of the pipes is cold so I assume it is the compressor. What's the best solution for that?

It could be a defective compressor or compressor wiring. I don't consider working on the compressor wiring a DIY project. Great care needs to be taken working around a suspect compressor.
