Seasonal energy efficiency ratio

Seasonal energy efficiency ratio or SEER is a measure of how well an air conditioning unit cools a room over a period of time. This is important because using air conditioning units can be expensive and can have an impact on the environment.

Think about your mom's car - when she needs to go on a long trip, she checks how many miles per gallon the car gets. This tells her how much gas she needs to put in the car and how much it will cost. SEER is kind of like miles per gallon for air conditioning units.

When you turn on an air conditioner, it uses electricity to cool the room. The SEER rating tells you how much electricity the unit uses to cool the room. The higher the SEER rating, the more efficient the air conditioner is - it will use less electricity to cool the room.

SEER is measured over a whole season because the temperature and humidity can change throughout the year. This means that SEER takes into account how well an air conditioner is able to cool the room even when there are changes in weather.

To sum up, SEER is a number that measures how well an air conditioning unit cools a room while using the least amount of electricity. A higher SEER rating means a more efficient air conditioning unit that will help save money and the environment.
