Quick answer
A condenser replacement swaps the outdoor unit, which contains the compressor, condenser coil and fan. It works when the indoor air handler is young enough and a matched condenser exists for it. In Miami the new unit must be anchored to Florida wind-load code and, near the coast, should have corrosion-resistant coil protection.

Condensers fail in Miami for three main reasons: salt air corroding the coil, compressors wearing out after years of heavy run hours, and storm damage from flooding or flying debris. When the rest of the system is sound, replacing just the outdoor unit can be the right call.
The key word is matched. A condenser and air handler are rated and warrantied as a pair, and a mismatch costs efficiency and can void coverage. We confirm the indoor unit's model, size and refrigerant, then select a condenser that forms a certified matched combination with it. If the air handler is old or uses R-22, we price a full system instead.
Outside, the details matter as much as the equipment. The pad has to be level and sound, the unit anchored with rated tie-downs, the line set flushed or replaced, and the electrical disconnect and surge protection in good shape.
