What is SEER? EER? HSPF?
Seasonal Energy Efficiency Ratio (SEER) is most commonly used to measure the efficiency of a central air conditioner. The higher the SEER, the more efficient the system. SEER measures how efficiently a cooling system will operate over an entire season. In technical terms, SEER is a measure of 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. This measure of efficiency is specific to the temperate climate in the middle of the U.S.
Energy Efficiency Ratio (EER) is a measure of how efficiently a cooling system will operate when the outdoor temperature is at a specific level (95 degrees F). The higher the EER, the more efficient the system. In technical terms, EER is the steady-state rate of heat energy removal (i.e. cooling capacity) by the product measured in Btu per hour divided by the steady-state rate of energy input to the product measured in watts. This ratio is expressed in Btu per hour/watt.
Both SEER and EER are included in the ENERGY STAR specification because each rating indicates the energy efficiency of the product under different conditions. The 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. The higher the HSPF, the more efficient the heat pump. In technical terms, HSPF 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.
Ductless heat pump facts
A ductless heat pump is a highly energy-efficient heating and cooling system that runs without the energy losses associated with the ductwork of a central forced-air system. As it doesn't require ducts to carry conditioned air, it is the preferred system for additions to your home, newer homes that only require a small space conditioning system or areas of your home that you wish to condition in zones.
Other benefits include:
- Ductless heat pumps use between 25 and 50 percent less energy to heat your home
- An ultra-quiet fan evenly circulates air, eliminating hot and cold spots
- Installation in your home is inexpensive, simple and quick, which makes for little or no disruption
- Ductless systems come standard with air conditioning, so you can get rid of window units
Air-source heat pump facts
An air-source heat pump is a high-efficiency heating and cooling system that can deliver between one-and-a-half and three times more heat energy to a home than the electrical energy it uses.
A less efficient panel of electric coils kicks in to provide additional indoor heating when outdoor temperatures fall below 40 degrees Fahrenheit, so it's generally not a preferred system for regions with sub-freezing winter temperatures.
TIP: The installation of a heat pump or air conditioner can sometimes cause a fluctuation in the power supply when your equipment starts. This may result in a visible flicker of the lighting in your home or your neighbors' homes.
To ensure that your heat pump installation does not have a negative effect on power quality, it's important to discuss this issue with your contractor. For additional assistance, call a PSE Customer Construction Services specialist at 1-888-321-7779.
