Seasonal energy efficiency ratio, or SEER, is a measurement used to rate the efficiency and performance of a heating pump or central air conditioner unit. The higher the SEER number, the more energy efficient the unit is and the more money you will save on your electric bill. Higher-rated heat pumps are also more expensive to purchase. SEER numbers typically range from 10 to 14, but some manufacturers have higher SEER ratings. Knowing what SEER number your unit is rated will help you evaluate an older heat pump and whether it would be worth replacing or repairing.
Look at the side of the heat pump for an energy sticker. The SEER rating should be listed on this label.

Locate the manual and look inside it for the SEER rating. It will most likely be listed on the first couple of pages or on the manual's cover.
Open the manufacturer's website. Type your heat pump model number into the site's search function. A description, including the SEER number, may result. A manual might also be available for download. The model should be listed on a sticker on the side of your heat pump and in your manual.
Call a local heat pump dealer and tell him your make and model number. You can also schedule an appointment. A representative will come out, evaluate your heat pump, inform you the SEER number and possibly recommend the best course of action if you are having heat pump issues.
