As the others mentioned you'll need to insure that your heater ductwork and fan are up to the task, and you'll probably need to change out the control box at the heater. You'll also need to properly size your A/C compressor and A-coil based on house size, windows, insulation, etc. It's not rocket science, but there are some nuances to doing it right.
I've installed systems in a past life, but still hired someone this year to replace both units.

Not interested in doing it myself - just want to understand the system so that if I do decide to upgrade the house I know what I'm being sold.
