We're interested in replacing our existing 14 year old, 4 ton heat pump and we have a couple of questions. We live in No. Virginia, in a single family home that is 1.5 stories with skylights and several sliding glass doors.
1. Should we have heat/loss measurements made on the house to determine if the unit is properly sized?
2. Which Carrier would be better, the Infinity 17 or the Performance 13? We have quotes for both. I understand that the Performance has a scroll compressor vs the two speed in the Infinity. Which might work better for our area of the country?
