SEER Rating Chart for Air Conditioners [Calculator]

Are you confused with SEER calculation for your AC? We are happy to help you.

SEER (Seasonal Energy Efficiency Ratio):

It illustrates to you how your air conditioner or heat pump is powerful. If the SEER rating is higher, your air conditioner uses less energy.

How much money can you save by improving your money in electricity? You’re not sure if you want to upgrade to 14 SEER or 25 SEER air conditioning. Do you want to know how much cooling needed for your home to reduce the bill?

Formula:

A SEER rating is a rate of cooling output of an air conditioner in a regular refrigerant season, which is divided by the watt-hour consumed energy.

How to find your SEER rating:

In most A / C units, SEER Ranking has a yellow sticker named “Energy Guide”. Find the starting digits of the model number. For example, if a model number beginning with 10AC, the air conditioner has a SEER rating of 10. The model number is available in the manufacturer’s label, the listed model, and serial number are listed.
