So now I'm learning that Nissan Leaf owners are also very intelligent!
The house isn't very big at all. Really, it's small. It's a 3 bedroom 2 bath, but I think it's no more than 1200 square feet. MAYBE 1500 square feet if you are pushing it.
However, like I've mentioned before, it is drafty. Ever since this issue with the electric bill, I have not made a peep of a complaint about the temp in the house. Most of the time I haven't even been there as I've been charging the Leaf after work.
The windows definitely need replacing, and like I've stated, something is going on with the heat as when it comes on, the house becomes unbearably hot even though the thermostat is set to 69. But then when the heat goes down, it gets chilly again.
As far as the average temps for this time of year, one thing I've had to get used to about Houston (as I'm a native New Yorker) is that it gets cold at night. So in the daytime it may hit 70 degrees, but at night the temp can drop to 35. So there's no way we can be in the house at night when it's 35 or 40 degrees outside, and not turn on the heat. But the AVERAGE may make it seem as though it's warmer overall than it has been.
