Do you replace a bad capacitor for a central ac with the same size?

Typically a bad capacitor is a sign of a weakening Compressor in the unit. Rule of thumb: If the unit is 20+ years old, you would be putting a band aid on it by replacing the capacitor. If you decide to try and get by with an older system for a few more seasons, I recommend to put a new capacitor on the unit with a hard start system installed on the compressor. You can normally have this done for under $300.00. And back to your question; capacitors are sized depending on the size of the unit. Check your tonage of the unit and bring the capacitor with the correct tonage to a Parts house and they will make sure it is properly sized. Hope this helps.

Can you replace a capacitor that is smaller in size but same value?
If, by smaller in size, you mean physical size, then yes. You just need to keep the same capacitance and minimum voltage rating. Also, in a power supply filter application, you need to consider the maximum RMS current rating.
What are the Darwbacks of non-polar capacitor over polar capacitor?
A: Polarized capacitors can be smaller in size as compared to a non polarized in the same capacity
How do you know what size capacitor to get for a 2 ton central air unit?
It should say on the compressor and the fan motor labels.

What size capacitor?
Capacitors come in various sizes, your question is to non specific (capacitor for WHAT) for a detailed answer.
Is it OK to use an unpolarised capacitor in a circuit where there was originally a polarised one?
Well... Maybe yes, maybe no. It depends on two things. First, the physical size of the non-polarized capacitor may well be larger than the original size of the polarized capacitor, so it might not fit. Second, you have to consider the RMS current rating of the capacitor. Often, a polarized capacitor, such as an electrolytic capacitor, is intended to be used in a power supply, and is rated for a certain RMS current. A non-polarized capacitor, however, might not be rated for the same or higher RMS current, so it would not be able to handle the load.

How does the size of an electrolyte capacitor vary with its capacitance value?
A: Capacitance vary directly with the area applied the bigger the area the bigger the capacitor. There is another element that will increase the size that is the rating of the capacitor voltage since more material will have to be used to insulate the plates
What is the net force of a capacitor?
This question does not make sense. For what use, or what kind, even the size are all factors of a capacitor. Look up the definition of what a capacitor is and then ask a real question.
