Hi - we live in Atlanta where it gets really hot in the summer and not too cold in the winter. We have two story house and need to replace the HVAC for the main level. We replaced the HVAC for the upstairs two years ago. Here are some details:
Our main level system is a Carrier that is 15 years old. It is a 2.5 ton A/C Unit with an 80K BTU furnace. I do not know the SEER Rating because it is so old.
Contractor 1 recommends a 3 ton Trane XR15 with matching coil and a XR80 Furnace. When asked about a Variable Speed furnace, this contractor said it is a waste of money to have in Atlanta.
Contractor 2 recommends a 2.5 ton Trane XR13 with matching coil and a XV80 Furnace. This contractor was insistent on us using the variable speed furnace and didn't want to give us a quote on the XR80.
Do any of the pros have an opinion of which one of these would be a better fit for our house?
