Here I am, searching google for stores in my area that carry energy efficient air conditioners. Many are marked as energy efficient, even with a high rating, but suck up 15amps of electricity! Between 5-6,000 btu. Wow, that's amazing. Watch your electric bill soar with that.
Is the general populace really that unaware of this? There are much more efficient systems, but one has to do some serious legwork to find them.
