· WHAT DOES "SEER" STAND FOR?

Seasonal Energy Efficiency Rating.  Efficiency ratings are like gas mileage - the higher the rating, the more efficient the product is.

· WHAT DOES AFUE STAND FOR?

Annual Fuel Utilization Efficiency.  This measure gauges heating fuel usage.  The Infinity 96 gas furnace receives up to 96.6% AFUE.

· WHAT DOES HSPF STAND FOR?

Heating Seasonal Performance Factor.  This measurement gauges the heating mode of heat pumps.  Most new units have ratings from 7.0 to 9.4.  The Infinity 17 heat pump receives up to 9.5 HSPF.

· WHAT IS ENERGY STAR?

Carrier Corporation has determined that certain products meet ENERGY STAR guidelines for energy efficiency.  Look for this logo on Carrier products.

· WHAT TYPES OF REFRIGERANT ARE AVAILABLE?

FREON

Freon-22 Refrigerant has been used in cooling systems since its debut in 1930.  However, the Clean Air Act of 1990 prohibits the production of Freon-22 based air conditioners and heat pumps by 2010, and Freon-22 production by 2020.  As Freon-22 production declines, its cost is predicted to rise.

PURON

Carrier was the first to introduce a new, non-ozone-depleting refrigerant called PURON - a full six years ahead of the competition - paving the way for the future.  PURON refrigerant is chlorine-free, so it doesn't damage the Earth's ozone layer.  And, as other refrigerants become less available, PURON refrigerant will be the refrigerant of choice for years to come.
