My parents-in-law are thinking about getting A/C finally (?!).

They are trying to figure out what that will do to their electrical bill.

Here?s some stats:

Area: Littleton
Provider: Xcel
House: early 80?s construction, no vaulted ceilings; ~2100sqft
Current non-A/C summer electrical bill: ~$95

So, folks in that area with Xcel electricity and A/C, what?s your average monthly electric bill in the summer?

thanks!
