Hello,
In April I had my cAC compressor replaced and system recharged. It blew cold air for several month but now it no longer blows cold air and it sounds like the cluth is engaging and then disengaging and same thing over and over. Any ideas on what it may be? I check the Freon and it’s reading good.

Thanks in advance!

Symptom of low refrigerant or a plugged oriface tube.

Thank you! Gauges read Freon is good so must be the later.

I really appreciate it!

You read High And Low side or like most get cheapest low side only gauge and think the system is happy?
At what pressures when the compressor is on?
Because Plugged O-tube etc will try to push High Side gauge to the max and High Side Switch will shut off or compressor etc fails or burst.

Thank you for the info I didn’t check the high side as well.

Thanks again!
