I suspect that your air conditioning systems are not up to snuff.

The tiny little light on the thermostat that says emergency heat is the clue.

When that light comes on, you are basically turning on 6 or 7 hair dryers.

Straight glowing red wire heat is about 3 times more expensive than using a compressor to move heat.  (heat pump)

That light comes on during defrost  (unit in air conitioning (cooling) mode) for just a few minutes or

That light comes on during periods when the set temperature is more than 3 degrees below the actual temperature.

Look for long periods of that light on.  If so, time for a tune up of your A/C system(s).

My system never kicked in emergency heat at a balmy 68.
