What do the terms SEER and HSPF mean?
• SEER, (Seasonal Energy Efficiency Ratio), is most commonly used to measure the efficiency of a central air conditioner or heat pump. It measures how efficiently a cooling system will operate over an entire season. The higher the SEER, the more efficient the air conditioner. As of January 2006, manufacturers are only allowed to produce units with a 13 SEER rating or higher. • HSPF, (Heating Seasonal Performance Factor), is the measurement used to rate the efficiency of the heating mode within your heat pump. As with SEER, the higher the rating the higher the efficiency. Most manufacturers offer heat pump ranging from 6.8 to 9.4 HSPF.
