“We have 3 levels, each has it’s own central air system, but NONE are used. In order to cut costs over long term we’ve added separate room air conditioners/heat pumps (the ones that go through the walls) in the kids and guest bedrooms), and for the master we have installed a split level air system just for the master (all doors closed). ”
I can’t imagine this isn’t a massive part of the drain. Small room based units are horribly inefficient and in heat mode really drain.
Also, how many and how long are the lights on? Are they 60W lights or larger?
Okay, having read the rest of this thread, it’s a joke right? Many fridges, wife sets the heat to 78, AC to 65, leaves the fridge door cracked open…
Don’t underestimate the power drain by those big TVs in standby waiting for you to hit the remote on.
