Default Honda Civic 08 A/C compressor shut off

My A/C will turn on at idle, but as soon as I rev the engine above 1700 rpms it shuts off and doesn’t come back on. I had the freon replaced. They assured me there were no leaks or air pockets. What are my next steps?

Worn out A/C clutch or bad thermal sensor... common failures on the "K" series A/C compressors.

Are are you talking about the AC Clutch Compressor Relay, or something else?

True dat.

OP, it is not going to be something simple and cheap like an A/C relay. There is a slim possibility that your system is overcharged and your line pressures get too high off idle and thus, the system shuts down. I still think the logical problem is that the A/C compressor clutch itself is worn and slipping under load.

Wouldn't hurt to try replacing the relay. Simple $7 part, but I do agree it is likely the compressor clutch. Ran into the same problem recently.
