A new system would consist of a new airhandler (the inside unit which houses the evaporator coil, fan, expansion valve, etc. ) and the outside unit which houses the compressor, condenser coil, reversing valve, etc. This assumes that your line set (copper liquid and vapor lines) and thermostat are OK and compatible. Ideally, they will also evaluate your duct work and replace/repair any parts that are leaking or poorly installed. It would also be advisable for them to do a cooling load calculation on your house to ensure that the right sizes system (in terms of tons of cooling) is installed. The quality of the installation is usually more important than the choice of which brand of equipment. The incremental cost of better equipment is usually small and worth considering.
