# How much energy does an air conditioner with an 9.7 EER save as opposed to a 10.7 EER?

A 10.7 EER units uses

E.E.R. was calculated by dividing an HVAC unit's rated cooling output (measured in BTUs per hour) by the unit's rated energy input (measured in watts of electricity), under particular input/output temperature, humidity, and condition conditions.

The percentage difference can be directly compared because, at the nominal rating conditions, this is comparable to the vehicle fuel "mpg" rating. The cost difference will vary depending on the actual climatic conditions and power costs.

In actuality, the value with the higher value consumes less energy!

To calculate the energy saved by upgrading from an air conditioner with a 9.7 EER to one with a 10.7 EER, you subtract the energy used by the higher EER unit from the energy used by the lower EER unit.

Given: EER1 = 9.7 EER2 = 10.7

Energy saved = (1 / EER1) - (1 / EER2)

Energy saved = (1 / 9.7) - (1 / 10.7) Energy saved ≈ 0.103 - 0.093 Energy saved ≈ 0.01

Therefore, the air conditioner with a 10.7 EER saves approximately 0.01 units of energy compared to the one with a 9.7 EER.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
