Finishing 2nd story of cape code, HVAC advice
 
I'm soon to be working on the electrical/hvac of my unfinished 2nd story. The upstairs is 2 bedrooms and a bathroom, approximately 475 sq ft, so it isn't that big. I'm trying to figure out what the best options are considering the size:

*fit to use existing heat pump on first floor
*install new heat pump for second floor
*install baseboard and some other A/C system

****
I have a heat pump system on the first floor (Carrier 25HBR), how can I determine if it has enough "juice" to heat the upstairs as well? (IE what numbers do I need to run). If possible, I dont see a simple way to run the duct work upstairs, does anyone have an idea what it would cost for an HVAC pro to retrofit this?

***
Would baseboard heating be any more/less efficient than the heat pump? I would imagine all things being equal it would be better considering I can turn them down when not in use for specific rooms.

***
What would my options be for A/C if I did not opt for the entire heat pump system?

Thanks in advance!

If you use your current heat pump.
Your aux heat will need to come on sooner to heat the house.

how many rooms will you have upstairs?

I'm assuming the first floor system was sized for that floor when installed, if so I would not add any other load that system. Check it out for size, Oh that's right the ductwork that could be a problem.

Well let's see 2 bedrooms and a bath I would consider a two zone split mini heat pump system, just hang the indoor coils on the walls and run the connecting lines and electrical with a remote control thermostat.

Wa LA no duct work, nice and quite, and different system from first floor, and the best, separate controls for even temperature.

It will be 3 rooms. Thanks for advice, I've scheduled an estimate. Now at least I have some lingo to throw out there if the guy says I need a gold plated flux capacitor.

chazman sorry forgot the bathroom.

Watch out for the price of that gold plated flux capacitor.
