Which would save us more money? Help!
After just two weeks in our 1897 home, my husband and I are having discussions about how we can more easily regulate the temperatures between the first and second floors (as well as our utility bills). For example, it's currently 70 degrees on the first floor, but even with the AC running, it's still 77 in the baby's room.
The windows are all original to the house. Would we be better off replacing all of them or putting in a dual zone AC/heat system? We're concerned about bills, but also about managing to keep everything comfortable on both floors. Are there any other options?
I've never lived in such an old home, so I feel totally clueless. Help!
