This!
I had a 1100 sq ft 2-storey townhouse - 8 years old, built terribly, every window had a draft, and furnace was not an efficient, likely cheapest one out. I always thought my bills were outragous.
Moved to a 4 level split built in '82, 2700 sq ft, solid house, new windows, new high efficiency furnace, and i'm paying more than half of what i was in my old location.
(disclosure - this is gas and power in one bill, but the same in both cases).
The new house also has A/C which we run in the summer.
Cheers
