The outdoor unit is nice and quiet, it uses the scroll instead of bristol compressor.
The furnace has a better board on it so its improved over older models, how much, only time will tell for sure.
Make sure you get a humidistat for that vs blower.
York doesn't have the txv installed on the coil, the contractor has to install it himself. Thats the biggest complaint I have about them so far.
If you get the heatpump, the deforst board is also a duel fuel board, so you only need the bonnet sensor, and you got the best of both worlds.
