When you are looking for a new air conditioner there are a few things that you want to keep your eyes open for. The first being the SEER (Seasonal Energy Efficient Ratio) ratings. This rating measures the machines ability to cool and how much electrical power is used in the process. An air conditioner that uses air ducts can have a rating of up to 21 while ductless and geothermal A/Cs, also known as a Panasonic mini-split, are able to get into the 30’s. This ultimately means that the higher the SEER rating the more energy and money you will end up saving in the long run.
The other type of rating is called EER (Energy Efficient Ratio) ratings. The difference between the EER and SEER rating systems is that EER has been used longer and it uses a formula that has constant temperatures. SEER, on the other hand, does have a formula that fluctuates based on the region and the temperature of the seasons. EER, however, is more focused on those who live in dry climates and high temperatures. This type of rating is also commonly used for engineering calculations.
Either way these ratings are a great point of reference for anyone who is shopping for a new A/C system. If you are looking for a system that is cheap up front then you are going to want to pay even more attention to these ratings. Because the higher the ratings, the more expensive the device can be. Even if the rating is only one number higher it can be $1,000 more expensive.
