Seer And Hspf

When you are out to buy a heating or a cooling unit there are certain terms that you need to be aware of so that you do not end up making a wrong choice and making unnecessary expenses. SEER and HSPF are nothing but efficiency ratings of your heating and cooling unit. Every heating and cooling unit are assigned one of these ratings as per the U.S. Department of Energy. To put it simply, making an informed purchase is far better than buying something that you did not want to buy at all. Along with SEER and HSPF, AFUE is also another efficiency rating assigned to heating and cooling units.

Now let us have a detailed look at the meanings of SEER and HSPF rating.

SEER or the Seasonal Energy Efficiency Ratio is normally assigned to air conditioners but many manufacturers associate SEER with heat pump as well. Here it must be noted that SEER applies only to cooling so when you are purchasing Heat Pumps or Ductless Units you should look at HSPF or AFUE ratings for the best bargain. SEER is basically the total cooling output divided by the amount of electricity used during any given season. It is usually calculated in the period when the air conditioner is used like in late spring, summer or early fall. Another related efficiency rating related to SEER is the EER or the Energy Efficiency Ratio. It gives the energy efficiency of the unit throughout the year. However, the SEER rating is considered more accurate as most people do not operate their air conditioners during the winter season. As far as the efficiency of the air conditioners are concerned, higher the SEER rating more efficient is the unit. This is because it uses less energy and has lower impact on the environment. Nowadays, air conditioners have SEER ratings as high as 13. Hence, if you have a unit that has a lower SEER rating it is recommended that you upgrade to one that has a higher SEER rating. This way you will easily save on your monthly utility bills.

HSPF on the other hand stands for Heating Seasonal Performance Factor and it is mainly used to measure the heating efficiency of heat pumps and ductless heat pumps. However, sometimes it is also used to measure the overall heating and cooling efficiency of a system. HSPF is basically the amount of heat generated divided by the amount of electricity used that is calculated as an average of the heating season. To put it simply, HSPF is the opposite of SEER. Thus both these ratings are required to determine the efficiency of any compressed refrigerant system that offers both heating and cooling. As far as the efficiency of heating units are concerned, higher the HSPF rating more efficient is the system. This means with a higher HSPF rating heat pump you can make more energy savings. Earlier heat pumps did not come with a high HSPF rating but now you can buy a heat pump with a HSPF rating as high as 7.7. There are some heat pumps which have a HSPF rating as high as 10.

Thus, it is recommended that whenever you set out to buy an air conditioner or a heat pump you should be well aware of these terms and make an informed choice. Rather, you should purchase a unit that gives you gain in the long run.
