I am upgrading both upstairs and downstairs AC/Heat units in my house. Old units are both Train and are 17 years old and cost of repair vs. replacement seems to point towards replacement. Contractor recommended the following:
Upstairs (AC + Gas heater)
- XR15 with XV80 furnace
Downstairs (gas pack)
This is our primary residence and we are in NC (gets hot and humid in the summer). Do we have the right system here or do you recommend something else?
