If you have started researching your air conditioner replacement you’ve probably noticed that HVAC has its own jargon and it can get confusing. If you want to get the most out of your research, there are some common terms you should know. A lot of them pertain to efficiency, which will help save you money. So when you’re researching an air conditioner replacement the team at Climate Zone wants to help you go into your research with the knowledge you need to make the best decision.


What is EER? EER is the energy-efficiency ratio and it measures how efficiently your system will work when the temperatures outdoors reach a certain level. The higher the rating, the higher the efficiency, the higher your savings.

ENERGY STAR® Certification

You’ve probably seen the ENERGY STAR logo on your appliances, but what does it actually mean? The Environmental Protection Agency and the Department of Energy created ENERGY STAR in 1992 as the international standard in energy-efficiency. ENERGY STAR products are good for the environment and your wallet. In order for an air conditioner to qualify as an ENERGY STAR product it goes through third party testing and must meet the requirements set up by the EPA. One of those requirements is that if a products costs more than a less efficient product, the consumer will recover that investment over time through savings on their energy bills. When the time comes for your air conditioner replacement, be on the lookout for the blue energy star logo.

SEER-Seasonal Energy Efficiency Ratio

SEER is an acronym for Seasonal Energy Efficiency Ratio and measures the energy efficiency of your air conditioner. The difference between a SEER and an EER rating is that a SEER rating takes into account the efficiency of your unit at different temperatures, or seasonally, as the name implies. It factors in the highs and lows of the temperature in your area. Again, just like the EER-rating, the higher the SEER-rating, the higher the energy efficiency.
