Hi All - Brand new install, approx 1800 sq feet over two stories, northeast MA. Have been quoted a Carrier condenser, 24APA536 and a Carrier coil, FV4CN003. I have two questions:

1. Are those two a good match for each other?
2. I have forced hot water baseboard, the coil quoted above will be in the attic, do I need to worry about cold migrating down from the attic through the ductwork during the winter? If so, is there a typical remedy?

Thanks for your input
