Install in the shoulder seasons — spring or fall. Off-peak pricing is better, scheduling is flexible, and you are not making the decision under pressure during a heatwave.

It must come from a Manual J load calculation, not square footage alone. Oversized units short-cycle: they cool fast, shut off before dehumidifying, and leave the house cold and clammy while wearing out the compressor.
In hot climates with long cooling seasons, yes — the efficiency gain compounds over the season. In mild climates the payback period often exceeds the equipment life, and a mid-range unit is the better buy.
If it is of similar age, usually yes. The indoor coil and blower have to be matched to the outdoor unit for rated efficiency, and doing it in one visit costs far less than two separate installs.
