OK - you have a few start-up issues. Nobody is always perfect all the time. Especially if they have employees. <g>
But the bottom line is that you still did the right thing going with the heat pump instead of the propane.
My opinion is not a perfect substitute for actual engineering, but four tons of cooling doesn't seem all that far off the mark for a 2500 square foot house in the Carolinas.
And, even if it is oversized for cooling - look at the bright side: it will do a better job of heating.
The conventional view serves to protect us from the painful job of thinking.
Just for fun, let us know, how you like the warm air coming out of the vents and if your happy with a heat-pump,
