Understanding aircon: SEER and EER ratings explained

When shopping for a new air conditioning unit, you'll likely come across two important ratings: SEER and EER. These ratings are used to measure the efficiency and performance of air conditioning units, and they can help you make an informed decision when choosing the right system for your needs. Remember you should always get an air conditioning engineer to do your ac installation in your home.

What is SEER?

SEER stands for Seasonal Energy Efficiency Ratio. It is a measure of the cooling output of an air conditioning system over a typical cooling season, divided by the energy it consumes in watt-hours. Essentially, SEER is a measure of how efficiently an air conditioner uses electricity to cool your home.


The higher the SEER rating, the more efficient the system is at cooling your home. Most modern air conditioning systems have SEER ratings ranging from 13 to 25, with higher ratings indicating better energy efficiency.


What is EER?

EER stands for Energy Efficiency Ratio. It is a measure of an air conditioning system's cooling output in BTUs (British Thermal Units) per hour, divided by the energy it consumes in watt-hours. Unlike SEER, EER is measured at a constant temperature and humidity level, rather than over a full cooling season.


While SEER is a more comprehensive measure of efficiency, EER provides a more immediate snapshot of an air conditioning system's efficiency at a specific point in time.


Which rating is more important?

Both SEER and EER are important indicators of an air conditioning system's efficiency and performance. However, SEER is typically considered the more important of the two ratings, as it provides a more comprehensive measure of an air conditioning system's efficiency over a full cooling season.


In addition to SEER and EER ratings, there are other factors to consider when choosing an air conditioning system, such as the size of your home, your budget, and your specific cooling needs. A reputable HVAC contractor can help you navigate these considerations and choose the right air conditioning system for your home.


In conclusion, understanding SEER and EER ratings is crucial when shopping for a new air conditioning system. By choosing a system with a high SEER rating, you can ensure that you're getting a unit that is both efficient and cost-effective to operate, helping you stay cool and comfortable all summer long.
