EFFICIENCY PAGE
THIS IS SOME KNOWLEDGE ABOUT EFFICIENCY RATIO'S FOR HEATING AND
AIR CONDITIONING EQUIPMENT IF YOUR IN THE MARKET FOR A NEW
SYSTEM.
YOU MAY CHECK FOR THE FOLLOWING:                                                       
*GAS HEATING (AFUE) ANNUAL FUEL UTILIZATION EFFICIENCY*
FURNACES MANUFACTURED BEFORE 1992 CAN HAVE (AFUE) RATINGS AS
LOW AS 60%. TODAY'S STANDARD FURNACES HAVE (AFUE) RATINGS OF 78%
TO 80% WHICH ARE CONSIDERED MID-EFFICIENT. FURNACES WITH (AFUE)
RATINGS OF 90% OR HIGHER ARE KNOWN AS HIGH EFFICIENT. THE (AFUE)
OF A FURNACE IS THE PERCENTAGE OF GAS USED TO HEAT YOUR HOME, SO
THE HIGHER THE BETTER. FOR EXAMPLE AN 80% EFFICIENT FURNACE
UTILIZES 80% OF IT GAS INTAKE TOWARDS HEATING YOUR HOME AND THE
OTHER 20% IS A WASTE. THE MAXIMUM EFFICIENT FURNACE AVAILABLE IS
ABOUT 96%.
*AIR CONDITIONING (SEER) SEASONAL ENERGY EFFICIENCY RATIO*
AIR CONDITIONERS MANUFACTURED PRIOR TO 1992 COULD HAVE A (SEER)
RATING AS LOW AS 6.0 .THE GOVERNMENT NOW HAS MANDATED A MINIMUM
(SEER) RATING OF 13.0 IN 2005 WHICH IS MORE EFFICIENT THAN WHAT MAY
BE COOLING YOUR HOME. HIGH EFFICIENT AIR CONDITIONERS WILL HAVE A
(SEER) RATING OF AT LEAST 13.0 OR HIGHER. THE MAXIMUM EFFICIENCY
AVAILABLE HAVE A (SEER) RATING OF ABOUT 18.0 .
*HEAT PUMP HEATING (HSPS) HEATING SEASONAL PERFORMANCE FACTOR*
HEAT PUMPS ALSO HAVE EFFICIENCY RATINGS. THE GOVERNMENT
MANDATED STANDARDS FOR HEAT PUMPS NOW TO AN EFFICIENCY RATING
OF ATLEAST 7.5 (HSPS). MOST HEATPUMPS MANUFACTURED BEFORE 1992
HAVE (HSPS) RATINGS OF 5.0 OR BELOW. TODAY A (HSPS) RATING OF 7.5 OR
HIGHER IS CONSIDERED "HIGH EFFICIENT". THE MAXIMUM EFFICIENCY
AVAILABLE HAVE A (HSPS) RATING OF ABOUT 11.5 .

*SO IN GENERAL THE HIGHER THE AFUE, SEER, AND HSPS RATING THE LESS
IT WILL COST (UTILITY WISE) FOR YOU TO OPERATE YOUR HEATING AND AIR
CONDITIONING SYSTEM. SEE THE CHARTS BELOW FOR MORE INFORMATION.*
