So I'm dealing with a carrier package unit in which the compressor was already replaced for the same, exact reason of the pulsating noise that is coming out of the compressor ( which I will say along with the pulsating noise comes additional vibration and also raises concerns of pipes snapping. ) System runs properly and performs properly. System installed September 19, 2022. Compressor replaced May 23, 2023. Carrier tech support is not really assisting that well. Here are all of my readings. The only thing that has changed was me reclaiming charge as per tech supports instructions to obtain 21 superheat. At this rate, the technical support is going to send my video to the factory, which I'm assuming is the engineering department to try to figure out what is happening. Does anyone have any ideas or has encountered this before.?

I have the video of the surging noise I am referring to but I can't post it for site

Nvm engineering got back and stated the noise that wasn't there previously is normal operation. And we are just going to exchange this equipment at this point under dealer conditions.

That's a rotary compressor.

Superheat is too low, Txv?
