| What S.E.E.R to buy? Greater Operational Efficiency For every $100 spent to cool your home using a 10.0 SEER air conditioner, a 17.0 SEER air conditioner cost you approximately $59. Actual savings will depend on the efficiency or your current system compared to the efficiency of a new system. Replacing systems older than 15 years (6 or 8 SEER), could save you even more. |
Seasonal Energy Efficiency Ratio (SEER), is most commonly used to measure the
efficiency of a central air conditioner. It measures how efficiently a cooling system will
operate over an entire season. The higher the SEER, the more efficient the air
conditioner. Technically speaking, SEER is a measure of equipment the total cooling
of a central air conditioner or heat pump (in Btu) during the normal cooling season as
compared to the total electric energy input (in watt-hours) consumed during the same
period
Energy Efficiency Ratio (EER) is a measure of how efficiently a cooling system will
operate when the outdoor temperature is at a specific level (95F). In technical terms,
EER is the steady-state rate of heat energy removal (i.e. cooling capacity) by the
product measured in Btuh divided by the steady-state rate of energy input to the
product measured in watts. This ratio is expressed in Btuh/watt. The higher the EER,
the more efficient the air conditioner.
Both SEER and EER are included in the ENERGY STAR specification because each
rating indicates the energy efficiency of the product under different operating modes.
SEER rating more accurately reflects overall system efficiency on a seasonal basis
and EER reflects the system’s energy efficiency at peak day operations. Both ratings
are important when choosing a product.
Heat Seasonal Performance Factor (HSPF) is the most commonly used measure
of a heat pumps heating efficiency. It represents the total heating output of a heat pump
(including supplementary electric heat) during the normal heating season (in Btu) as
compared to the total electricity consumed (in watt-hours) during the same period.
HSPF is based on tests performed in accordance with AHRI 210/240 (formerly ARI
Standard 210/240)1.
