are you meaning a biger condensor? The job of the condensor is to condense or liquefy the high pressure or high temp. vapor from the compressor. If you used a bigger condensor more then what is adaquate for the system you will only make the ac not work at all or cause major problems. Why? Think how the condensor works. Its going to liquefy the high pressure vapor from a vapor) to a liquid form. Which the vapor of course starts from the top of the condensor and passes down through the condesor coils as it flows across the condensor coil fins, it changes to a high pressure warm liquid. This liquid goes from the bottom of the condensor through the line to the drier. The condensor is a heat exchanger! I don't see why his ac system wouldn't perform adaquate for this complete size of the system.
