What does SEER and AFUE mean?

SEER stands for “Seasonal Energy Efficiency Ratio”. Basically it tells you how efficiently it converts electricity to cooling comfort. The higher the SEER rating, the more efficient the system. By federal law all units must be a 10 SEER or higher. Coolray recommends having a Comfort Consultant to come to your home and perform a heat load calculation to insure the proper size unit is installed. This is a free service to our customers that may help you save money and increase your indoor comfort.

AFUE stands for “Annual Fuel Utilization Efficiency”. This rating tells you how much of your heating dollars are converted to heat energy put into your home and how much is lost up the flue pipe. Most older furnaces are 50% to 60% efficient. That means that for every dollar you spend for gas from your utility company, $.40 to $.50 cents are being sent up the flue pipe to the outdoors. Federal law mandates that all furnaces being produced today be at least 80% efficient. Coolray offers several different sizes of furnaces up to 96% efficient. That means that for every dollar you spend on gas from the utility company $.96 is converted to heat your home and only $.04 is sent out the flue pipe.

A Coolray Comfort Consultant can visit your home, perform a heat load calculation and recommend the proper system to keep you comfortable and save you money. In many cases homeowners have saved enough on their utility bills to more than cover the investment of a new comfort system.
