Some don't have that capacity.

That's a double capacitor for both the fan and compressor. The 5mfd is for the fan and the 45mfd section is for the compressor. Lightning blows those things out all the time. The 5/45 may work OK until you can get the proper replacement but get a 440volt rated capacitor instead. The higher voltage rating will hold up longer than the lower voltage 370volt cap. There is a real problem in the HVAC industry with Chinese manufactured capacitors that don't hold up and don't meet voltage/mfd ratings and have a high failure rate. There are websites that sell American made capacitors that have become popular albeit much more expensive. ^_^

Usually compressors make a distinctive noise. You can also check the amp draw. But for now, I'd suggest to replace the capacitor. Fairly inexpensive item and a common culprit. Finding one on Sunday? Only if some HVAC company near you is willing to sell you one. Might need to wait till Monday.

Sure. The fan has to carry the heat away. With poor air flow, it's not going to do much cooling.

You should be able to tell the sound of the compressor motor from the hum of the contactor/relay. Also, normally the pressure line is warm, the suction line cold, at the unit. With it underperforming, the difference will be less, but I would still think you'd feel some difference. From the description, sure sounds like it's a bad cap.
