So my compressor fried last summer and I recently installed a new compressor and receiver/drier. I attempted to charge it but it was extremely slow to take refrigerant. So I figured the expansion valve was clogged and replaced that. It still doesn't want to take a charge at anywhere near the speed it should and I am getting tired of this heat! Anybody want to point me towards the next item I should check for blockage?

Did you completely evacuate the system using a vacuum pump?

Are you trying to recharge the system with the "aerosol can" refrigerant? If so you'll never get the system to fully recharge. It might not even be enough to trigger the compressor clutch to engage. You'll need at least 2.5-3 lbs. of refrigerant for the whole system (R134 = low pressure side around 25-40 psi / high pressure side 230-250 psi).

They will fill it pretty damn close. I've done it before and there was no problem. The canned R134a will definitely fill the system with 2.5-3lb, and if you are not careful it will also easily overfill the system. There will just be some compressed air present. However, this is not a question of whether I'm using the correct filling procedure. Some part of the system is congested. I don't have any friends in the business and I'm certainly not going to go have refrigerant filled for some ridiculous price only to find that the system still isn't working correctly and that I have to empty and refill anyways. After I get the system working properly then I would get it vacuumed and filled legitimately. I'm sure you can understand that.
