Can this be done by a homeowner? Is this a sort of plug and play installation or is it more complex that should be done by an AC professional?

by asking the question before being electricuted you may have the right stuff obiwan.
Turn off all power, pull the disconnect and kill the breaker just for fun, The capacitor will hold a charge so don't touch the terminals. unscrew strap, look at wires, one post is com(common), one is fan, and one is herm(hermetic compressor). maybe use your camera phone here to note location of wires. touch each terminal to the other with a screw driver to discharge it (playing with electricity here careful) . Hook the wire to the same terminals on the new one , strap it in (if you cant use the same strap make sure the terminals will not touch any metal) power it up. if the motos are not over heated it should go.
Be good to your fellow man not nice there is a difference.

Ok, when the tech was here a few weeks ago he recommended that I replace my dual capacitors but he didnt tell me that they would fix my problem. Which is why I held off on doing it. But now its a few weeks later and my air conditioner constantly runs during the day and will not drop below 74 degrees. Power bill arrived yesterday and was over $200. In your opinions, would this problem be due to a problem with the dual capacitors? The problem a couple weeks ago was that my lines froze up. Had to defrost and the tech ended up only adding some freon. Said he couldnt find a leak.

That is what the problem was when it was repaired a few weeks ago. It started getting hot in the house and went out to the unit to notice ice on the line.
I replaced the filter then, so it is brand new (3 weeks old). For instance right now, the thermostat is set to 73 but yet it is 75 inside the house so the unit will just contstantly keep running.
The hvac tech now is telling me it is probably my dual capacitors that need to be replaced because he said they werent reading correct? I have heard elsewhere that dual capacitors are either good or bad, that there is no in between?
Please help for I cant afford $200 power bills throughout the summer, or $150 trip fees every time the tech shows up.
House is approx. 2,000 SF. Carrier AC unit. I dont know the tonnage or the seer of the unit for it is not written anywhere on the label. It is about a 15 year old unit. Here is the label...

The dual capacitor on your 1992, 2 1/2 ton, 10 seer, single phase condensor is not causing your ice. You probably have a refrigerant leak in your evaporator coil.
For $30 you can measure your cap to see how weak it is.

Thank you very much. How did you figure that out?
Found some new information tonight after going underneath the house. The sump pump that is used to pump out the water that the unit builds up was not working. Took off the cover to check the coils on the unit under the house and it was full of water. Coils are clean as could be. Used a shop vac to pump the water out. Got the sump pump working. Could this be a cause?
The tech that was here a few weeks ago used a meter such as that to measure the capacitors. Im not sure what they measured at but he said they were a little low and suggested replacement.

17 years with Carrier.
The CK in your model number tells me this is a 10 seer.
The 30 in the center of model number indicates 30,000 btu (2 1/2 ton)
The suffix 300 in the model number indicates 230 volt single phase (although your nomenclature also states this)
The first 4 digits in the serial number indicate week and year of manufacture.
