SEER which is expanded as Seasonal Energy Efficiency Rating is the rating that can help you calculate the energy efficiency ratio of your air conditioner. It is defined as ‘The unit cooling output during a typical season divided by the total electric energy input during the same period.’ So to know the energy efficiency rating of your air conditioner you are going to buy or have already bought, check its SEER rating. The higher the SEER rating the lesser will be the energy consumption. The cost of the unit is directly proportionate with the SEER rating, as the SEER rating increases the cost will also increase.
The units that are now available are with around 13 to 16 SEER rating. You can also find units that have a rating of as high as 20. An air conditioner with the rating of 13 SEER is the common and is comparatively cheaper. Since such units are affordable most of the people settle with a 13 SEER rated air conditioner. The US government has now put regulations for a minimum SEER rating of 13 for all air conditioners manufacture from now on. If you live in a warmer area where you experience heat four about 4 to 6 months and above then you need to go for a higher SEER rated unit so as to save money from your energy bill. If the usage is more then it will be worth investing in a high rated SEER air conditioners or else it is advised to settle with a SEER rating between 13 and 16.
