If the compressor fails, you can opt to have only the condenser replaced, leaving the indoor components in place. This costs less than a full AC replacement, but we rarely recommend it. Replacing the condenser alone risks a mismatched system that runs inefficiently, and it doesn't come with a new warranty.
