Shopping for a new air conditioner can be daunting, especially if it’s been more than 15 or 20 years since you last purchased an AC unit. Over that time, air conditioner technology has changed immensely, and the AC systems of today are smaller, quieter, faster, and more energy-efficient than ever before. BTUs and EERs are common measurements used today to define how energy-efficient an air conditioner is. To help you select the right unit for your home, here is a closer look at what these two important acronyms mean and how they will affect your energy bill.
A British thermal unit (BTU) is a precise measurement of the amount of heat necessary to raise the temperature of one pound of water one degree Fahrenheit. All air conditioners have a tested BTU rating. The higher the BTU rating, the more effectively the air conditioning unit will cool a large area of your home. Window air conditioners might be rated at 10,000 BTUs, while a typical 2,000-square-foot home might have a 60,000 BTU central air conditioning system. To accurately size an air conditioner for your home or apartment, contact your heating and air conditioning specialist.
The energy efficiency rating (EER) of a new air conditioner is a measurement of how efficiently it will cool down a room in relation to the amount of power it will consume. To determine a unit’s EER, its BTU rating is divided by the wattage the unit uses while operating. For example, if a 10,000-BTU air conditioner consumes 1,200 watts of electricity, it has an EER of 8.3. Higher EER numbers mean better energy efficiency and lower cooling costs.
