“Yes the total sf matters. Unless you have a large part of it closed off to HVAC you are paying to heat/cool 5500 sf.”
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). So we’re not heating/cooling entire floors, just rooms that have their system on.
How much would you all estimate are being drawn by systems in the “off” position (i.e. computers, big screen TVs, DVD players, DVRs, etc). Would it make “that big” a difference to unplug them instead?
