I may be confused here but I keep seeing American websites speak of units that are around 10-12 EER, yet in Australia we are meant to have some of the strictest requirements in relation to energy efficient a/c units our minimum EER over on average is around 2.9 EER. Surely I must be overlooking something here as the US units can't be that much more efficient !!

Please help??
