Thanks, everyone. These are exactly the kind of answers that I have been looking for. However, in reading them, I now have follow-up questions related to the heat pumps.

Can you explain more about the "heat strip" in the heat pump?

Is it something that can be added after purchase?

How does it work to help in the lower temperatures?

Does it serve like a radiant in a heater and the heat pump blows air across it to get the heat out of it?

Sorry for all the questions, but when we order our unit in the future (not sure when - house not sold yet), I'd like to make sure I've done as much right as I can.

Thanks again. You all are always so helpful.
