A/C starts cold but goes ambient

Hello I have a heat pump/ac unit that starts out nice n cold but will stop cooling in an hour. I cleaned the coils. Fans spinning and compressor running. I recently replaced the Capacitor and Relay. I had a HVAC guy I trust came out and charge it with a little Freon and put some lubricant in the system being he thought it might be the reverse valve sticking. I have a couple questions but, any input would be appreciated.

When the compressor goes bad or overheats does it just shut off?

Is there a way to just force the system to stay on cold only buying me some time to replace the unit next fall?

It's an old Lennox hp22-261-2p.

Thank you for your time.

Welcome to the forums.

Sure if you don't mind a possible compressor explosion.

You can't force something to work if it's defective !
You had a tech there.... he should have been able to tell you what the problem is.
