the past few nights, the temp drop down to the 30s/40s.. so far I have both systems running at around 68 deg. the ave usage is about 15 KWH per day.. The spike was about 1.5 KWH (fujistu 24k unit) when I turn up the heat. The outside unit is so quiet, It is barely noticeable.
Now I set the fujitsu unit to economy mode, which suppose to reduce the spike even more. It just takes longer to reach the set temp.
