Energy Efficiency 101: Vocabulary

Let us decode a few words related to energy efficiency and explain how using these terms can help you get the system that matches you and your home, whether you are considering a new air conditioner or furnace.

First things first: We’ve noticed one trend across the board with these terms. The higher the number, the higher the efficiency. This typically will result in a larger energy savings for you, ultimately reducing cost.

AFUE Rating – This stands for the Annual Fuel Utilization Efficiency Rating. Why is this important? This tells you how efficient your furnace is, meaning how much fuel your furnace actually uses versus what percentage is wasted. This is helpful to know as the higher the number, the more money you are likely saving.

COP – This one means the Coefficient of Performance, and is used to measure your heat pump’s efficiency when it is in heating mode. Geothermal products tend to have this type of rating associated with them.

EER – Energy Efficiency Ratings are a source of interest for those with geothermal systems, air conditioners, or air source heat pumps. It measures cooling efficiency.

HSPF – This term deals with the efficiency of heat pumps while in heating mode. You want a high number, like with all of these figures. The industry required minimum for the Heating Seasonal Performance Factor presently is a 7.7

SEER – Defined as the measure of how the cooling process of air conditioners and heat pumps are rated, the Seasonal Energy Efficiency Ratio is another number that can help you be more efficient with your energy and help you save more money.

These elephants find their way to keep cool...learn the terms and find a way to keep cool for you!
