Are you sure it is on the other side.
Panels are usually wired like this except for some old panals like push a matics panels.
1 2
3 4
5 6
7 8
and so on
Line 1 or leg 1 is 145&8
Line 2 or leg 2 is 236&7
This is setup this way so when you put in a 2 pole breaker you get 208-230 volts AC.
Just because the furnace is on the right side & your TV is on the left does not mean they are on differant lines.
I do not know how much you know of electrical panels.
