If you're wondering what a good EER rating for an A/C unit is, it is 8.5 and above. The higher the rating, the more efficient the A/C unit is. Also, consider looking for the ENERGY STAR label. It indicates that the A/C unit uses 10% less energy to operate.

Anyhoo, what dies EER mean?

Energy Efficiency Ratio (EER), also commonly expressed as Energy Efficiency Rating, gives you an insight about how much cooling capacity the unit provides from a specific amount of energy used. Every air conditioner is assigned with a specific EER.

Brief, is 9.5 EER good? The average EER rating of portable AC units is about 8.5. That means buying ones below EER 8.5 is not advisable and buying those above 8.5 is quite a smart move efficiency-wise. The most energy-efficient portable AC unit (Whynter Dual-Hose) has an EER rating of 11.2.

Anyways, how does EER compared to SEER?

EER rating is the calculation of the energy efficiency of an ac unit at one temperature, whereas, SEER is the measurement of the energy efficiency of an air conditioner of an entire season at different outside temperatures.

Is a higher EER rating better?

A room air conditioner's efficiency is measured by the energy efficiency ratio (EER). The EER is the ratio of the cooling capacity (in British thermal units [Btu] per hour) to the power input (in watts). The higher the EER rating, the more efficient the air conditioner.

What is a good energy efficiency rating for a window air conditioner?

EER rating = 12,000 BTU / 1,200 W = 10 Here are the benchmark efficiency levels for window air conditioners: EER below 9 = Low-efficiency window AC units. EER between 9 and 10 = Average-efficiency window AC units.

How do you use EER?

EER stands for Energy Efficiency Ratio. The EER rating for an air conditioner is calculated by dividing the BTU (British Thermal Units) rating by the wattage. For example, a 12,000-BTU air conditioner that uses 1,200 watts has an EER rating of 10 (12,000/1,200 = 10).

How much energy do I need per day?

How do I calculate my daily energy intake?

To determine your total daily calorie needs, multiply your BMR by the appropriate activity factor, as follows:
  • If you are sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2.
  • If you are lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375.
  • How do I choose a good air conditioner?

    Proper air conditioner sizing starts with determining the square footage of the room, by multiplying your floor's length by its width.
