HVAC - AFUE & SEER

What does it mean?  In the heating and cooling systems have two different means of determining the efficiency between them.  To know what the efficiently of a boiler or furnace AFUE is used, which is the Annual Fuel Utilization Efficiency is the ratio of heat output.  For example a boiler or furnace of an AFUE of 95% means 95% of the energy in the fuel heats the home and 5% escapes through the exhaust.  On the cooling side is SEER which means Seasonal Energy Efficiency Ratio.  It is the ratio of cooling delivered by a system, measured in BTUs to the cost of electricity to run the system. The higher the SEER , the more efficient the system.  The minimum SEER for new units is 13.  This would be 25% more efficient then an older 10 SEER unit.  The higher the SEER you need to calculate how long it will take you to recoup the costs of the higher SEERs.  Feel free to contact me at: findit@LehighValleyRealty.com
