Does this mean my A/C compressor is on its way out?

[SyberTiger]

I know I have a very small leak in the a/c system but to keep it going a bit longer before I make repairs I've been recharging the system by adding as needed. I'm guessing from the manifold gauges that the high pressure reading is telling me the compressor is on its way out as it doesn't appear to be able to get the high pressure side up.

From what I could tell, when I took these pictures the refrigerant level was likely near the right amount. You can see my ambient temperature reading and humidity reading below. The chart at the bottom tells me my high pressure side should have been closer to 200 psi.

If you have experience with the a/c system I'd like to hear your thoughts on this.

I don't. But I can state that, your chart is based on a new, 100% good as they get, compressor. Compressors lose efficiency with wear and tear. Plus, in your case, you only think the charge quantity was adequate; it may not have been. I agree, though, your "high-side" pressure is low, but why, it's not possible to say.

Generally, a small leak continuing for a considerable length of time, while being replenished from time to time, will display itself as an oily-looking spot. Have you been unable to see such evidence. If the leak is internal to the plenum, perhaps the evaporator core having a leak, it would not be visible. One common leak point is the compressor shaft seal. imp
