Will this unit replace model CPLE30-1A?

Because your old unit is 2.5 tons, a closer match would be GSZ140301. Also, we strongly recommend replacing your coil/air handler alongside your condenser. If those are also older models, then its likely they may be nearing the end of their life as well. Buying the full system altogether rather than just the individual units will save you a lot of money on installation and shipping/liftgate fees.

If you have any further questions, please call us and we will be happy to assist you.
