It's the other way around. One unit of energy to remove three units of heat. The best starting point is the government mandated minimum SEER of 13. The Wiki article on SEER works this out. The money quote is: A SEER of 13 is approximately equivalent to an EER of 11, and a COP of 3.2, which means that 3.2 units of heat are removed from indoors per unit of energy used to run the air conditioner. That's the minimum. Anything higher than SEER 13 is proportionally more efficient. https://en.wikipedia.org/wiki/Seasonal_energy_efficiency_ratio https://en.wikipedia.org/wiki/Seasonal_energy_efficiency_rat...
