Guys i replaced the expansion valve and now the problem seems to be gone. Pressures equalize slowly. Will let you know if problem comes back.
Really thank you for the support provided.

Remember that service valve caps must be intact to seal a system - check those !!! Checked this already. No issues with the valves or caps. I have some doubt about compressor itself as well. Because pressures equalize as soon as i turn off the system. Did some research in the internet and it was me...

Probably you are right. But then why couldnt we catch the leak with pressure test ? Tried with UV dye as well.
Can expansion valve leak from somewhere other than the connections?

You have a leak. It is undercharged, just a few days after service. I believe its supposed to blow cold air at those pressures. While AC is on with engine idle i have around 30 psi low side and 150 psi high side Should really measure such pressures at bout 2000 rpm. At 2000 rpm at 100F, I would exp...

You have a leak. It is undercharged, just a few days after service. They did a pressure test to find leaks and found nothing. Besides, static pressure and working pressures are very good as i mentioned. I believe its supposed to blow cold air at those pressures. Please correct me if im wrong. What ...

Guys, please help me with your expert opinions. My car is honda civic 2008. AC is not cooling. Static pressure is 100psi at 100 F temperature. While AC is on with engine idle i have around 30 psi low side and 150 psi high side and never cycles. When i turn off the AC, pressures equalize instantly ba...
