We are in the process of deciding between two heating and cooling systems. Our house is 13 years old, 3000sq.ft. and the current furnace is chimney vented.
It is between the Infinity 96 system(96% AFUE) by Carrier with the 17 seer heat pump or a York Affintiy System (80% AFUE)with a 14 seer AC unit.
The price difference is about $800 more for the Infinity system. We live in the Philadelphia area. Any suggestions??
