We have this house --
How long would one expect a house like this to go from 70F to 60F? We program the temp to be 70 during the day, drop to 69 at 10pm and then
60 at 10:30pm. At 7:30am it begins its climb to 69.I'm just trying guage whether or not a 70 to 60 drop is good or bad from 10pm to 7:30am, or 9.5 hours. The overnight lows are typically around 15 to 25F. I'm just trying to get a handle on whether I should look for air leaks, insulate better, etc.
