EER VS. SEER: HOW DO THEY DIFFER FROM EACH OTHER?

Eer Vs. Seer: How They Differ From One Another

There are both Energy efficiency ratings EER and Seasonal energy efficiency rating SEER ratings to consider when considering air conditioning. Ratings play an integral role in choosing the right air conditioner for your office or home. EER vs. SEER are explained here briefly to help you know the importance of these ratings and to help you make an informed decision.

What’s EER?

Energy Efficiency Rating or EER measures the energy efficiency of your air conditioner at a specific temperature outdoors, such as 95 degrees Fahrenheit. The higher the rating, the more efficient the air conditioner. EER is determined by dividing the input of the electrical power measured in watts by the air conditioner’s capacity to cool using British Thermal Units or BTUs.

What’s SEER?

Seasonal Energy Efficiency Ratio or SEER is the proportion of the air conditioner’s ability to cool efficiently over the cooling season, comparing the unit’s energy via the Watt-hours. EER ratings are the calculation of the energy efficiency under a specific temperature. SEER is the measurement of the efficiency of the energy of the air conditioner during variable temperatures outdoors.

Which Rating Is More Important?

Both ratings have importance when considering an air conditioner. Different circumstances will require different ratings.

EER is the efficiency of the unit during peak cooling times as calculated at peak temperature.
SEER is the calculation of the efficiency of the energy of the unit at a variable outside temperature and will include both the highs and the lows of the cooling pattern of the home.

If your location exceeds 95 degrees Fahrenheit, you’ll want to consider the EER rating the most. If you have moderate temperatures and climates, then focus on the SEER ratings.

What’s The Highest EER Rating On An Air Conditioner Unit?

These will vary depending on the capacity of the unit. Seek out EER ratings that are in the range of 9.4 to 10.7 to ensure that you’re getting the best air conditioning unit for your needs.

Is A Higher EER Rating More Important?

The higher the EER rating the more efficient the air conditioning unit. However, these come with a higher price. Just remember that the performance of your air conditioning unit will far outweigh the price of the unit.

What’s A Good Energy Efficiency Rating?

You’ll want to look for an energy efficiency rating of at least 6.0 for your air conditioning unit. You’ll save a lot of money on your running cost if you have a higher EER rating.

Can I Trust A BTU Rating?

The BTU rating is high on some Air conditioning units. BTU ratings can’t always be trusted. Oftentimes the manufacturers will overstate the BTU ratings to sell more air conditioning units. Don’t consider just the BTU ratings when choosing your air conditioner.
