I'm renting a 2200 Sqft house in Houston. It's new construction with nice double pane windows and decent insullation. I just got my electricity bill for December and it's $500.. I've had larger homes and never paid over $200 in Houston, and I wasn't even home for a week in December.

The bill shows 3000 kWh usage which is equivilent to running over 40 100W light bulbs 24/7 for the whole month. (I am pretty conservative on ussage, keeping lights and fans etc off most of the time)

I keep the thermosdat set on a modest 68 (on from 4:30pm to 7:30 AM - Off during the day time) and December was not a cold month here.
When the heater kicks on our lites dim slightly, and it seems to me that something isn't quite right with the unit, the wiring, or the breaker box.

It is running off two 60 amp breakers and up in the attic one of the power supply lines is slighty warm and the other isn't. I assume one is supplying the aux heater. Is this correct?

Should I get someone out to look at the unit? Is there some checks I can make? I'm fairly handy with some HVAC background.

The unit is aprox 7 years old.

Eye carumba.. Yeah a buddy of mine was up in my attic a few months ago and said I had a heat pump. I believed him because he sells AC units..

So what was the give away that there isn't a heat pump?

I'm thinking about getting a few more space heaters to get me through the rest of the mildly cold days here. 20kw is rediculous.

With 20 KW of strip heat. you often have 2 power supplies. The one provides power for the blower motor, control system, and teh first 10 KW of strip heat.
the other power feed supplies the second 10 KW of strip heat.

The first wires has roughly 45 amps being drawn on it.
the second one when the second set of 10 KW is on, will have roughly 41 amps drawn on it.
