Heating Terms and Definitions
AFUE, Annual Fuel Utilization Efficiency:
An efficiency rating for heating systems, based on a standard formula provided by ASHRAE (an industry association). The AFUE is helpful to homeowners avaluating systems because the AFUE rating represents the actual, season-long, average efficiency of the furnace, rather than just the peak-power efficiency.

Cooling Terms and Definitions
SEER, Seasonal Energy Efficiency Rating:
An efficiency rating for air conditioning systems, based on a standardized formula provided by the AHRI (an industry association). The formula creates a ratio of efficiency based on how much cooling output is provided (in BTU’s), compared to how much power is used to provide that cooling (averaged over the whole summer). The higher the SEER rating of a unit, the more energy efficient it is. As of January 2006, all residential air conditioners sold in the United States must have a SEER of at least 13. ENERGY STAR qualified Central Air Conditioners must have a SEER of at least 14. Read more at wikipedia….
Refrigerant:
A chemical that condenses from a vapor to liquid and, in the process, decreases in temperature.
